Full textAbstract:
Banana weevil, Cosmopolites sordidus (Germar), and striped weevil, Metamasius hemipterus (Linnaeus), are pests of global importance in banana cultivation that are traditionally controlled using synthetic insecticides. Plastic traps offer an alternative method to managing these weevils. However, the effectiveness of artisanal traps, considering color, odor, position, and their influence on trapping efficacy, has been largely neglected. Here, we assessed artisanal plastic traps for capturing banana weevils, testing two trap colors (yellow and brown), two positions (horizontal and vertical), and five types of attractants: pineapple; pineapple combined with molasses; pseudostem; pseudostem combined with molasses; and the pheromone Cosmolure in Ecuadorian banana fields. Under controlled conditions, trap color and position did not significantly influence the preference for C. sordidus and M. hemipterus (P<0.05). Field bioassays revealed significant differences in the capture of C. sordidus based on trap position and odor attractants. While trap position did not affect the capture of M. hemipterus, the choice of attractant influenced insect capture rates. Cosmolure was the most effective attractant for capturing banana weevils, whereas pineapple baits attracted the highest number of stripped weevils. Over 10 days, the number of captured insects decreased for both weevils across different attractants. Our findings highlight the potential of artisanal plastic traps as a valuable tool for the integrated pest management (IPM) of C. sordidus and M. hemipterus in banana plantations.

<strong>ABSTRACT</strong> In Kolhapur G-9 and Deshi varieties of banana Musa sp. are widely cultivated and attacked by weevils <em>Cosmopolitis sordidus</em> Germer and <em>Odoiporus longicollis</em> Oliver (Curculionidae : Coleoptera). The occurrence of <em>O. longicollis</em> on above said banana varieties was high from the months of June, September, October, April and May. More or less same trend of occurrence was shown by <em>C. sordidus</em>. G-9 variety was more susceptible to weevil attack than Deshi variety. Under laboratory conditions (27±1oC, 75-80% R.H. and 12 hr photoperiod), life cycle from egg to adult was completed with 32 days and 38 days on G-9 variety by <em>C. sordidus</em> and <em>O. longicollis</em> respectively. Sexes of both species were polygamous and mated at day and night in <em>O. longicollis</em> and at night in <em>C. sordidus</em>. The dispersal rate of <em>O. longicollis</em> was greater than <em>C. sordidus</em>. The wind velocity probably has less impact on dispersal on <em>C. sordidus</em> than <em>O. longicollis</em>. Collection and destruction of weevils, use of noninfected suckers for planting and use of 0.2 % dieldrin spray controlled the weevils at large extent. <em>Metarrhizium</em> sp. and Histerid beetles have also caused mortalities in larvae of weevils. <strong> Key words</strong>: Banana weevils, biology, ecology, control. <strong>REFERENCES</strong> Visalakshi, A., Nair, G.M., Beevi, S.N. and Amma, A.M.K.

Full textAbstract:
The pest status of Cosmopolites sordidus has been related to farm sanitation, environmental conditions and local weevil biotypes. This study was to confirm the inherent fecundity of endemic weevils, soil moisture effect and planting material health status that may contribute to weevil behaviour. Adult banana weevils were confined to plantain rhizomes, which were then subjected to four soil moisture regimens for 65 days. In another experiment to measure potential fecundity, weevils collected from the farmer&rsquo;s field were dissected to determine the internal egg follicles. Planting material with different initial weevil egg infestations on the pseudostem were confined below insect screening net in growing pots. Larva damage and stage populations were determined after 22 weeks. The results showed that weevils confined to plants under moisture stress had higher corm damage than irrigated and vigorously growing plants. A lower number of weevils were associated with plants under moisture stress than vigorously growing plants. The maximum number of mature egg follicles present in the ovaries of female weevils was 17. In general, the mean number of mature egg follicles was 4 per female adult weevil. Infested planting material with initial estimated number of 0.3 eggs per sucker resulted in 2.3 adult emergence and &asymp; 34% corm cross section damage after 154 days. The potential egg follicles albeit slow weevil population build-up reiterates the k-selected nature of the banana weevil. The egg follicles in adult female ovaries were high and comparable with weevils in other banana growing regions. The default health status of planting material was confirmed to be a contributing factor to weevil build-up in confinement. Soil moisture increased weevil survival but the improved plant vigour compensated for weevil damage.

Full textAbstract:
Artificial diets rapidly establish the effectiveness of chemical-based control strategies. Diets permit preliminary evaluation of active compounds, study in-vitro larval growth cycles that are usually inaccessible and produce uniform large consistent numbers of insects as needed. With no known artificial diet, banana weevils, have always been reared on field-collected banana rhizome (corm). This study, therefore, developed and examined the effect of commercial diet recipes fortified with susceptible banana corm powder on weevil growth and development. Subsequently, corm powders from different banana cultivars were also evaluated for weevil performance. Successful laboratory rearing of the weevils to adult stage on diet was achieved in 48 days compared to 36 days in the natural banana stem. The difference in weevil larvae performance reared different corm powder, presented a novel screening method for banana genotypes. For example genotypes, Culcatta-4 (AA), Cavendish (AAA) and Kayinja (ABB) showed 0-35% of adult emergences compared to 65% in susceptible genotypes. The diet developed can be used to perform rapid bioassay experimentation to screen potential candidate proteins or molecules for a transgenic approach. It has also shown potential for rapid screening of genotypes for resistance. Keywords: Resistant banana, Laboratory weevil rearing, Resistance screening.

The project is carried out in business partner Blue Garden Farm in Tanjung Jati, VII Koto Talago Village, Guguak District, and Regency of Lima Puluh Kota. The location has the potential to develop agriculture and animal husbandry. One of the many agricultural sectors in the region is bananas. People usually only use this fruit while others are wasted. In response to the above problems, a solution to the development and utilization of banana weevil to prepare IMO (Indigenous Microorganisms) was given. IMO is a group of microorganisms derived from natural ingredients that can accelerate the organic composting process. The carbohydrate content of banana weevils is relatively high, 66.2%, which will trigger the development of microorganisms during the fermentation process in the IMO producing process. It aimed to increase the economic value of banana weevil, providing another alternative for farmers to improve agricultural quality. This program used an empowerment method with several approaches, namely learning methods and mentoring with a team in solving problems. An evaluation was carried out to determine the knowledge of farmers' ability about the technology for producing IMO banana weevil. In this community service activity, farmers have made and produced MOL banana weevil. They have been used as a decomposer to manufacture liquid organic fertilizer/bio urine.

Full textAbstract:
Understanding of ecological interactions is necessary for the application of biological control. Banana is the second most produced fruit worldwide and the banana weevil (Cosmopolites sordidus) is the most important pest of banana and plantain. Its biological control remains challenging because of the robustness and cryptic behaviour of the adult and the hidden development of larval stages. Researchers therefore tend to favour conservation biological control of this pest. The commonly used methods for measuring the effects of natural enemies on the regulation of this pest focus on invertebrates and may underestimate the role of vertebrates on biological control. Using cameras, we recorded the predation of sentinel adult weevils in banana plots in La Réunion island that differed in weevil infestation levels and in animal biodiversity. To facilitate image analysis, we used background subtraction to isolate moving parts of image sequences and thus detect predators and predation events. Our cameras recorded only vertebrates as predators of adult banana weevils. The most important predator appeared to be the Asian shrew (Suncus murinus), which was responsible for 67% of the predation events. Other predators included the house mouse (Mus musculus), the oriental garden lizard (Calotes versicolor), and the guttural toad (Sclerophrys gutturalis). The exact time of predation events were determined from the images metadata. It was thus possible to identify predator foraging periods that coincided with activity of adult weevils. Our results confirm that images provide useful information for biological and ecological studies. Along with other recent studies, our results suggest that the role of vertebrates in biological control may be underestimated. Based on these results, we advocate for several management implications such as the installation of hedges, grasslands, and ponds to favour these vertebrate predators of the banana weevil, possibly also favouring other vertebrate and invertebrate natural enemies.

Organic Waste Management and its utilization. The aim of organic waste management and the use of banana hump liquid organic fertilizer is to reduce agricultural waste and increase its benefits in the agricultural cycle for the community in Lembang Burasia. With this program, the community can find out how to make liquid organic fertilizer by utilizing waste and materials found around the community. These activities include (1) socializing the use of banana weevils to become POC; (2) Training on how to make POC from banana tubers; (3) making banana tubers into POC; (4) application of the use of banana weevils as POC. This activity can run well in accordance with the planning and objectives of the activity. The implementation of this activity received support from both the head of Lembang and local residents, which was indicated by their involvement in implementing the activity. The results of this activity have also provided special skills for local residents who have been directly involved in the process of making banana weevil POC.

Full textAbstract:
Banana weevil (Cosmopolites sordidus, Germar) is a major pest in East African Highland Banana. The influence of crop nutritional status on weevil damage is poorly understood. Nutrient availability affects the nutritional quality of plants for weevils and may affect weevil damage. Here, we evaluate the effect of insecticides alone and in combination with fertilisers (N, P, K and Si) on weevil damage using data from two experiments in central and southwest Uganda. In the first experiment, we varied chlorpyrifos and application rates of N, P and K. In the second experiment, we varied the application rates of K and Si. Treatment effects were analysed using generalised linear mixed models with a negative binomial distribution. In the first experiment, chlorpyrifos reduced and N increased weevil damage, while P and K had no significant effect. In the K or Si application rates reduced weevil damage compared with the control. We conclude that the combined application of chlorpyrifos with K and Si fertilisers can contribute to weevil damage control on sites with low nutrient availability and should form part of integrated weevil management in bananas. Future studies should assess how much reduction in insecticide use is possible in EAHB with judicious input rates.

Full textAbstract:
Banana weevil (Cosmopolites sordidus) is the most devastating pest of banana and plantain worldwide, yet current control measures are neither effective, sustainable, nor environmentally sound, and no resistant farmer-preferred cultivars are known to date. In this paper, we examined the ability to induce RNA interference (RNAi) in the banana weevil via feeding. We first developed an agar- and banana corm (rhizome) flour-based artificial diet in a multi-well plate setup that allowed the banana weevils to complete their life cycle from egg through the larval instars to the pupal stage in an average period of 53 days. Adults emerged about 20 days later. The artificial diet allowed the tunneling and burrowing habits of the larvae and successful metamorphosis up to adult eclosion. Adding dsRNA for laccase2 to the artificial diet resulted in albino phenotypes, confirming gene-silencing. Finally, C. sordidus was fed with dsRNA against a selection of essential target genes: snf7, rps13, mad1, vha-a, vha-d, and lgl for a period of 45 days. 100% mortality within 9–16 days was realized with dssnf7, dsrps13, and dsmad1 at 200 ng/mL artificial diet, and this corresponded to a strong reduction in gene expression. Feeding the dsRNA targeting the two vha genes resulted in 100% mortality after about 3–4 weeks, while treatment with dslgl resulted in no mortality above the dsgfp-control and the water-control. Our results have implications for the development of RNAi approaches for managing important crop pests, in that banana weevils can be controlled based on the silencing of essential target genes as snf7, rps13, and mad1. They also highlight the need for research into the development of RNAi for banana protection, eventually the engineering of host-induced gene-silencing (HIGS) cultivars, given the high RNAi efficacy and its species-specific mode of action, adding the RNAi approach to the armory of integrated pest management (IPM).

Banana germplasm with 17 different accessions for resistance were screened against banana stem weevil, Odoiporous longicollis in Koduru region of Kadapa district (Andhra Pradesh). All the accessions had infestation of stem weevil but with varying percent infestation. The 17 accessions of germplasm had weevil infestation ranging from 10.0–100 percent in 2012 with maximum infestation of 100 percent in red banana (AAA genome) followed by Bontha selection-88.88 % (ABB), Karpuravalli-84.60% (AAB) and Ellakibale-64.7% (AB) and the lowest was inSugandhalu-10.00% (AAB). In the year 2013, the infestation was in the range of 13.00-90.40% and with respect to infestation levels in different accessions, and the trend remained same as the earlier year wherein the highest infestation was recorded in red banana-90.40% followed by Bontha selection with the damage of 83.50 %, Karpuravalli (79.80%), Ellakibale (70.00%) and least in Sugandhalu-13.0% (AAB). There was no correlation between number of adults observed and percent damage and similarly no relation can be drawn between percent infestation and height of oviposition, This implies that the infestation caused by the weevils varied in different genotypes and also this information will be further helpful in selecting the resistant germplasms for future.

The banana pseudostem weevil (BPW), Odoiporus longicollis (Oliver), is one of the most destructive pests of bananas that is seriously affecting the yield and quality of bananas. We isolated pathogens from banana pseudostem weevils in Xishuangbanna and Dongchuan, Yunnan, China, and explored their biological characteristics. The pathogenicity of the strains was verified through laboratory and greenhouse inoculation experiments. The results showed that four strains of fungi were identified and confirmed as Beauveria caledonica (Bc) via ITS-rDNA sequencing. Optimal in vitro culture conditions were found to be a photoperiod of 24 h light, 25 °C temperature, and 18 days on potato dextrose agar (PDA) medium with insect meal. Under these conditions, the Cs-1 strain achieved a colony diameter of 65.17 ± 0.74 mm and spore production of 1.24 × 108 cfu/cm2. The Cs-1 strain had the shortest lethal time (LT50) of 9.36 days at an inoculum of 1.00 × 109 cfu/mL, with a lethality of 86.67% after 20 days. The Cs-3 strain showed 77.78% lethality at 1.00 × 108 cfu/mL after 20 days. Despite variations in virulence, lethality did not correlate with major cuticle-degrading enzymes. The Cs-3 strain demonstrated effective biocontrol in greenhouse tests. Banana plants suffered significant damage without Bc-treated BPW, while the treated plantlets thrived. The mortality rate reached 82.78% after 35 days. This study marks the first identification of these entomopathogenic fungi (EPF) in Yunnan, China, highlighting B. caledonica’s potential for biocontrol application.

Abstract The banana weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) is an economically important insect pest of bananas. It causes up to 100% yield losses and substantial lifespan reduction in bananas. Advances in genomics, proteomics, and sequencing technologies have provided powerful pathways to genotyping disastrous pests such as C. sordidus. However, such technologies are often not available to the majority of rural subtropical African banana growers and pest control managers. This study was therefore motivated by the need to create cheap and easily accessible C. sordidus genotyping methods that could be deployed by banana pest control managers to the benefit of C. sordidus control programs in the tropics where such advanced technologies are not readily accessible. We used an in-house C. sordidus transcriptome from the an-ongoing study from which we mined an array of simple sequence repeat (SSR) markers. Of these, six highly polymorphic transcriptome-derived SSR markers were used to successfully genotype within and among banana weevil population genetic diversity of 12 C. sordidus populations collected from four banana-growing agro-ecological zones (AEZs) in Uganda. The developed transcriptome-derived SSR markers can be used by researchers in population genetics for characterization of the C. sordidus and identification of new genes that are linked to traits of particular interest. The significant genetic diversity revealed in C. sordidus provides pertinent information for integrated pest management strategies.

Fungal Volatile Organic Compounds (VOCs) repel banana black weevil (BW), Cosmopolites sordidus (Germar, 1824), the key-pest of banana [Musa sp. (Linnaeus, 1753)]. The entomopathogens Beauveria bassiana (Bb1TS11) and Metarhizium robertsii (Mr4TS04) were isolated from banana plantation soils using an insect bait. Bb1TS11 and Mr4TS04 were pathogenic to BW adults. Bb1TS11, Bb203 (from infected palm weevils), Mr4TS04 and the nematophagous fungus Pochonia clamydosporia (Pc123), were tested for VOCs production. VOCs were identified by Gas Chromatography/Mass Spectrometry–Solid-Phase Micro Extraction (GC/MS-SPME). GC/MS-SPME identified a total of 97 VOCs in all strains tested. Seven VOCs (styrene, benzothiazole, camphor, borneol, 1,3-dimethoxy-benzene, 1-octen-3-ol and 3-cyclohepten-1-one) were selected for their abundance or previous record as insect repellents. BW-starved adults in the dark showed the highest mobility to banana corm in olfactometry bioassays. 3-cyclohepten-1-one (C7), produced by all fungal strains, is the best BW repellent (p < 0.05), followed by 1,3-dimethoxy-benzene (C5). The rest of the VOCs have a milder repellency to BW. Styrene (C1) and benzothiazole (C2) (known to repel palm weevil) block the attraction of banana corm and BW pheromone to BW adults in bioassays. Therefore, VOCs from biocontrol fungi can be used in future studies for the biomanagement of BW in the field.

AbstractThe banana stem weevil, Odoiporus longicollis Olivier (Coleoptera: Curculionidae), is an important economic insect pest of bananas throughout the world. In this study, several important volatile substances were analysed to develop a semiochemical-based trapping technique for the control of O. longicollis. Electroantennogram responses of both sexes were associated with electroantennogram-active compounds (1-hexanol, 1-heptanol, cis-3-Nonen-1-ol, methyl jasmonate, and terpenoids such as (–)-linalool, (+)-(1R)-α-pinene, (–)-(1S)-α-pinene, and 1,8-cineole) and then were analysed using a Y-tube olfactometer. The results revealed that only methyl jasmonate and 1-hexanol elicited strong behavioural responses in O. longicollis. These two semiochemicals and the host plant extract were evaluated individually and in a mixture for their efficiencies in attracting O. longicollis in order to develop a semiochemical-based trapping technique. The methyl jasmonate + host plant extract and 1-hexanol + host plant extract mixtures captured more weevils (> 3.5 times) than the host plant extract alone did in both high- and low-altitude regions. The captured weevils were female-dominated, with a mean sex ratio of 1:1.29 (males:females). This is the first report on the use of methyl jasmonate or 1-hexanol and the host plant extract as a potential attractant in mass trapping and managing O. longicollis.

AbstractAn important step towards developing a successful integrated pest management (IPM) programme for the control of banana pseudostem weevil, Odoiporus longicollis (Olivier), a serious pest of banana in India, is the study of the population structure of the pest. In the present study, the genetic variation among 30 individual weevils of O.longicollis collected from six different locations was assessed by analysing the primary nucleotide sequences of the rDNA ITS1 and ITS2 regions. AMOVA, Mantel test, and the maximum likelihood trees of the haplotypes failed to reveal any phylogeographic structuring, which was confirmed by haplotype analysis and genetic differentiation estimates. The results indicate that the locations are not differentiated, i.e. there is gene flow between the locations. The star-shaped networks revealed a signature of demographic expansion that was confirmed by the different demographic tests. These results provide important information, which is essential for the development of suitable strategies for the control of this banana pest, as well as management of its resistance to insecticides.

Biotic constraints cause major crop losses and, hence, food insecurity in sub-Saharan Africa. This study documented the popularity, production constraints, pests and diseases, farmers’ perceptions on the severity of biotic constraints and the impact of related crop losses on household food security for the key root, tuber and banana (RTB) crops (cassava, potato, sweetpotato and banana). Farmer interviews were conducted in 2014 covering 811 households in Rwanda and Burundi. Farmers were asked to list their RTB crop production constraints, name insect pests and diseases of RTB crops, estimate crop loss due to pests and diseases, and mention if their household experienced any form of food insecurity due to pests and diseases. Cutworms and late blight in potato, banana weevils and banana Xanthomonas wilt in banana, cassava whitefly and cassava mosaic disease in cassava, sweetpotato weevils, and sweetpotato virus disease in sweetpotato were the most predominant pests and diseases reported. Crop losses due to pests and diseases for sweetpotato, banana, potato and cassava were estimated at 26%, 29%, 33%, and 36%, respectively, in Rwanda and 37%, 48%, 38%, and 37% in Burundi. Pests and diseases reduce the profitability of RTB crops, threaten food security, and constitute a disincentive for investment. Sustainable and affordable integrated pest management packages need to be developed.

Gunung Agung is a village in the Terusan Nunyai District, Central Lampung Regency, Lampung Province, Indonesia, with social diversity and cultural richness produced by its bustling community. Gunung Agung Village has geographical conditions that support the agricultural sector. The farmland covering a large village area is planted with various crops, especially cassava and sugarcane. The topography and fertile soil create good opportunities for productive agriculture. Cassava and sugarcane are local food sources and have significant economic potential for village communities. One effort to increase agricultural yields can be made by improving cultivation systems, such as implementing sustainable organic farming methods using liquid organic fertilizer. Fertilizer from organic and inorganic materials is used to increase soil fertility. Through community service activities, additional knowledge regarding liquid organic fertilizers, especially those produced from local microorganisms (MOL) banana weevils, is conveyed through various methods such as socialization and training in making banana weevil MOL. Thus, the people of Gunung Agung village can develop their understanding of increasing crop yields by utilizing liquid organic fertilizer based on banana hump MOL which can be obtained easily.

Banana weevil is a pest with a great impact on banana production in the world. The objective of this study was to evaluate the pathogenicity of the Kenyan entomopathogenic nematodes (EPNs) of genus Steinernema against the weevil Cosmopolites sordidus (Germar) under laboratory conditions. Adult weevils were trapped from banana fields in Maragua, Central Kenya and larvae extracted from the infested banana rhizomes. The adults were treated with three Kenyan EPNs Steinernema weiseri, Steinernema yirgalemense and the new Steinernema spp and with Steinernema carpocapsae ALL strain as a standard and plain distilled water as a control in five replicates. The treatments were 500ijs, 750ijs and 1000ijs per adult on petri dishes and 1000ijs, 3000ijs and 5000ijs per adult on pseudo-stems. The treatments for larvae in petri dishes were 300ijs, 400ijs and 500ijs. The adults were not susceptible to all the nematodes at all doses and preparations while larvae were highly susceptible to the four test EPNs at all concentrations. There was a significant difference at P<0.05 in the mortality of larvae between nematode Steinernema carpocapsae and Steinernema weiseri. A significant difference was observed between nematode Steinernema carpocapsae and Steinernema yirgalemense. There was also a significant difference between the new Steinernema spp and Steinernema weiseri and finally in the two nematodes the new Steinernema spp and Steinernema yirgalemense. All the test nematodes caused over 90 % larval mortality within 48 hours. The mean percent mortality of larva increased with nematode concentration for all the test nematodes. The results indicated that the four test EPNs significantly (P<0.05) caused high mortality within 24-48 hrs. The findings indicate that the banana weevil larvae are susceptible to the local entomopathogenic nematodes and potentially useful in the management of the banana weevil. It is however recommended that more research be conducted on the formulation and application technology to enhance their effectiveness in the field.

The banana weevil, Cosmopolites sordidus, is the most important pest of banana in the world. The effect of the pheromone releasing measure, a kind of ecological control method, was investigated over 2 years in Nanbao Farm, Lingao county, Hainan, China. The pheromone used was Cosmolure+, a commercially available C. sordidus aggregation pheromone. There were 3 treatments, including 0, 5 and 10 pheromone traps/ha. Pheromone lures were changed monthly at which time the traps were moved to a different location within the stand. There were no significant differences in mean catches of C. sordidus per trap in the most of the investigation period except September 2009. Meanwhile, there was no significant difference in plant damage between the pheromone treatment of 5 traps/ha and 10 traps/ha. The results also showed that the relationship between the mean number of weevils caught per month and average rainfall was not significant. Possible reasons for the 5 traps/ha efficacy in this study are discussed.

Gapoktan Tani Makmur is an association of farmer groups in Kartoharjo Village. The main product of Gapoktan is semi-organic fertilizer, namely organic NPK super granule with the trademark was ASLI (Alami Subur Lestari Indonesia). The problem faced is that Gapoktan is very dependent on factory microbes that were no longer produced in Purbalingga. There are many potential sources of beneficial local microorganisms, one of which comes from banana weevils. The purpose of this study was to describe the level of adoption and to analyze the factors that influence the adoption rate as the basis for the design of education about the manufacture of banana weevil MOL in Gapoktan Tani Makmur. Also, to determine the implementation, evaluate education based on the level of adoption and the factors that influence it. The method used is a quantitative approach with a survey method for data collection. The sampling technique uses random cluster sampling. The results showed that the measurement of the adoption rate before counseling was in the very high category of 82.9%, with the regression line equation Y = -2.695 + 0.124X1 - 0.558X2 + 2.182X3 + 1.958X4, with a determination coefficient of 0.829 or 82.9% . It means that the variable age (X1), an education level (X2), attitude towards change (X2), and courage at risk (X2) simultaneously affect the innovation adoption variable (Y) by 82.9%.

South Lampung Regency is one of the largest banana producers in Lampung province. One of the districts that is the largest banana-producing industrial center in South Lampung Regency is Sumur Village, Ketapang District. Sumur Village has good banana plantation potential, but utilization into processed products has not been carried out optimally. Usually bananas are directly sold to the market in a raw state. This can cause a lack of development of residents' creativity in utilizing resources and cause the economic value obtained by the community in the village to be less than optimal. Based on these problems, the PKM PisanGaul team held assistance in processing bananas into banana chips, banana brownies, banana ice cream, banana heart nugets and crackers from pisanng weevils, The mentoring activities carried out aim to open new insights of the community and also build an entrepreneurial spirit. The target of this community service is mothers in Sumur Village. In the implementation of this activity using two methods, namely socialization and training methods. After the training program was carried out, PKM partner participants consisting of PKK mothers and the general public of Sumur Village, had begun to be skilled in carrying out banana plant processing techniques into derivative products. So based on the Community Service activities that have been carried out with the title Pisangaul Lampung Digital Innovation of Agrosociopreneurship based on the utilization of the potential of banana plants in Sumur Village as a typical souvenir center of Lampung, it can be concluded that this training activity can: Improve the knowledge and skills of PKK mothers and the general public of Sumur Village in the field of processing and utilizing banana plants into various derivative products that have high selling value. Not only that, in this activity, direct sales of training products have also been carried out to several tourist attractions in the area and also through social media (Instagram) and websites that we have developed previously so that products processed by the people of Sumur Village are expected to be known by all people in Indonesia.

Dispersal of propagules of a pathogen has remarkable effects on the development of epidemics. Previous studies suggested that insect pests play a role in the development of Fusarium wilt (FW) epidemics in banana fields. We provided complementary evidence for the involvement of two insect pests of banana, the weevil borer (Cosmopolites sordidus L., WB) and the false weevil borer (Metamasius hemipterus L., FWB), in the dispersal of Fusarium oxysporum f. sp. cubense (Foc) using a comparative epidemiology approach under field conditions. Two banana plots located in a field with historical records of FW epidemics were used; one was managed with Beauveria bassiana to reduce the population of weevils, and the other was left without B. bassiana applications. The number of WB and FWB was monitored biweekly and the FW incidence was quantified bimonthly during two years. The population of WB and the incidence (6.7%) of FW in the plot managed with B. bassiana were lower than in the plot left unmanaged (13%). The monomolecular model best fitted the FW disease progress data, and as expected, the average estimated disease progress rate was lower in the plot managed with the entomopathogenic fungus (r = 0.002) compared to the unmanaged plot (r = 0.006). Aggregation of FW was higher in the field with WB management. WB affected the spatial and temporal dynamics of FW epidemics under field conditions. Management of the insects may reduce yield loss due to FW.

One of them is banana consumers who want a variety of good preparations, processed bananas themselves as well as processed bananas and stems. Almost in many areas banana trees can thrive well, including in the Village of Tenajar, Kertasemaya District, Indramayu Regency. Some of the social institutions that work on banana cultivation are farmer groups, farmer cooperatives, and other social institutions such as Islamic boarding schools. One of the pesantren that has a banana cultivation business is the Syubbanul Yaum Islamic Boarding School. The banana farming which is run by the pesantren community has been running for almost five years with a total of 20 members consisting of the board and parents of the santri guardians through the pesantren economic institution. This PKM activity is carried out for one year starting with the sequence of activities, namely; Socialization of activities, Training on fruit processing, weevils of organik fertilizers, Training on e-commerce-based financial management and marketing, Assistance to facilitate the establishment of professional and sustainable business institutions, Institutional assistance for guarantee the sustainability of PKM activities and evaluation as an effort to improve the methods and programs implemented. The results of the PKM activities have had a positive impact on the assisted communities, namely the increase in the community's ability to use banana weevils as material for making organik fertilizers. In addition, the community also has expertise in creating online marketing content, namely the availability of community groups in marketing processed banana products, namely banana chips with a market-worthy gasket concept. Through this competency, it provides benefits for increasing the willingness of the community to entrepreneurship in banana processing and has an economic impact, namely increasing the quantity of sales.

Full textAbstract:
East Africa highland bananas ( Musa sp., AAA- EA HB) are an important starchy food and cash crop in Uganda and the Great Lakes region of East Africa. Widespread reports of declining yields in Uganda since the 1930s and the low yields today do raise serious sustainability and food security concerns , especially as food demand increases with a population growth rate of 3.2% per annum . In addition, increasing urbanization continues to increase pressure on the banana system s, with bunches and leaves increasingly transported from rural areas to urban centres, leading to the continued loss of nutrients especially potassium. Actual yields on many smallholder banana farms (5 − 20 Mg ha − 1 yr − 1 FW ) in Uganda are far below the estimated potential yield (100 Mg ha − 1 FW ). Farmers cite soil fertility decline, pests ( banana weevils and nematodes) and moisture stress as the major factors responsible for yield decline. In response, several organic and mineral fertilization experiments have been carried out at research stations and in farmers’ fields in Uganda since the 1950s . Researchers have mostly reported responses to organic fertilizers, no or poor responses to Mg and P fertilization with some responses to K and N fertilization , but with yields that are far below the estimated potential . Although pests are controlled in so me trials, researchers have often failed to embrace a systems approach , quite often leaving out factors, such as moisture stress and soil physical conditions that affect the responses to fertilization . The government of Uganda in the National Development Plan 2010/11−2014/15 targets increased agricultural productivity for key staple crops like bananas in alleviating poverty in rural areas and ensuring national food security. In order to set proper banana research priorities to benefit farmers in Uganda , the objectives of this study were : to review past research aimed at reducing banana production constraints , identify opportunities and challenges facing the banana sector and put forward new research perspectives .

Full textAbstract:
The plantain banana weevil, Cosmopolites sordidus is one of the major constraints to the production of Musa spp globally, resulting in severe damages or even total crop failures. Laboratory testing with 4 different concentrations of the entomophagous fungus Beauveria bassiana (strain ACCC30108) revealed that fungal concentration as well as time (days after treatment, DAT) had significant impacts on adult weevil mortalities (P<0.05). Two high treatment concentrations used in this study (i.e.3mg/ml or 3x107 spores/ml and 2mg/ml or 2x107 spores/ml respectively) yielded similar results of between 4-92% mortalities of the weevil, but with LT50 of 26DAT and 28DAT respectively. The lower concentration (1mg/ml or 1x107 spores/ml and the control i.e. 0mg/ml or distilled water) on the other hand, respectively yielded 4-68%, with LT50 36DAT; and a paltry 4% mortality by end of trials i.e. 40DAT; suggesting that lower concentrations were insufficient to cause substantial weevil mortalities. Cadavers of dead weevils showed some white mycelial mass, visible only at intersegmental areas initially, but later covering the entire body, indicative of fungal (B. bassiana) cause of death. The study has confirmed B. bassiana as a possible biological control agent for management of this key pest. Follow-up tests in the field would ultimately reveal/confirm its true potential in this quest for a suitable, effective and environmentally-friendly biocontrol agent for sustainable management of this key pest.

The need for rice from year to year continues to increase due to the growing population of Indonesia, but this is not balanced with sufficient rice production. This is what makes it difficult for Indonesia to be self-sufficient in food so that efforts are needed to increase rice production nationally so that domestic rice needs are met. This panel aims to see the effectiveness of long soaking of rice seeds in MOL banana weevil on vegetative growth and yield of Ciherang variety rice plants. The research was conducted in November 2021 – March 2022 on open land of BPP Caringin, Legok District, Tangerang Regency. The study was conducted using the Randomized Complete Group Design (RKLT) method consisting of 5 treatments, namely control (without soaking MOL banana weevil), soaking rice seeds for 6 hours, 12 hours, 18 hours, and soaking for 24 hours. Each treatment was repeated 5 times so that there were 25 experimental units. Each experimental unit consists of three plants, the number of plants to be studied is 75 plants. Soaking seeds in MOL banana weevil for 24 hours gives the best results for the growth and production of Ciherang rice plants.

Full textAbstract:
The first encounter with Dr. Analyn A. Cabras occurred during an online conference hosted by Davao Oriental State University (DORSU) in 2023, streamed live on Facebook. Her passion for research on Pachyrhynchini weevils was immediately evident. Before formally meeting her, we—Daven and Graden—were plant hobbyists, drawn to the native flora of forested areas, unusual ornamental plants, and carnivorous species. Although our acquaintance with Dr. Cabras spanned just over a year, she became both a mentor and a friend. At her university laboratory, she entrusted us with taxonomic tasks, provided specimens for examination, and guided us meticulously. Her enthusiasm was palpable, especially when encountering specimens exhibiting unique evolutionary traits. She marveled at the intricate details, fostering our curiosity and deepening our appreciation for the field. Many of the beetles we photographed were common weevil species, often classified as agricultural pests in banana plantations and vegetable farms. Yet, Dr. Cabras never discouraged our enthusiasm. Instead, she reinforced the value of our observations, ensuring that each discovery—however seemingly mundane—contributed to a broader scientific narrative. In this paper, we recount our experiences as mentees of the late Dr. Cabras at DORSU. We hope to offer readers insight into her brilliance as a scientist, her generosity as a mentor, and her inspiring presence. Her pioneering research on Pachyrhynchini weevils has yielded groundbreaking discoveries in Philippine entomology, leaving a legacy that will resonate for generations to come.

Chemical insecticides have been commonly used against the black weevil, Cosmopolites sordidus, in banana plantations which caused huge economic and agricultural losses. Despite their benefits, pesticides can be hazardous to both humans and the environment. Intensive research in substituting chemical insecticides with biological control agents have been driven. The biological and molecular characteristics of ten strains of Metarhizium spp, isolated from dead weevils, collected in banana plantation in Côte d'Ivoire were studied. The study aims to identify the species of Metarhizium sp. The biological and molecular characteristics namely: length and width of the spores, colour of aerial mycelium as well as its variation over time, colour on the setback of the box, production of the diffusible pigment and the analysis of the region ITS (Internal Transcribed Spacer) were evaluated. The colonies presented at first a flat white mycelium cottony or fluffy appearance on which the spores formed small islets. After 21 days of incubation at 32°C. in the dark, the mycelium takes on the periphery a greenish coloration with a powdery appearance. The relief is fairly flat. The spores are ellipsoid in shape of 3 μm in length and 1 μm. The amplification by ITS-DNA PCR generated a specific fragment of 550 bp. The analysis of the ITS region of the sequences of these ten (10) isolates showed maximal correspondence with different strains of M. anisopliae and Metarhizium pinghaense.

This paper analyzes farmers’ perceptions regarding the consumption and production attributes of new banana hybrids in Uganda. The data were collected from a sample of 454 farmers. Following descriptive statistics and a factor analysis, a zero-inflated poisson (ZIP) regression model was estimated to understand the effect of farmers’ perceptions and other factors on the likelihood of adopting the new hybrids. The results show that, compared to a local variety (Mbwazirume), four of the hybrids are preferred in terms of production attributes but regarded as inferior with respect to consumption characteristics. Resistance to nematodes, tolerance to weevils and high performance in good seasons in terms of bunch size mainly explain early-stage adoption of the hybrid banana varieties. Hybrid M9 is regarded as having a relatively good performance with respect to most of the production and consumption characteristics. In collaboration with extension agents, variety M9 could be disseminated to a wider farming community that targets larger households, younger farmers and farmers with relatively large sizes of land.

In the health sector, the use of polyurethane (PU) as a basic material for medical devices still causes problems related to local and systemic infections. One of the most appropriate ways to overcome this problem is to synthesize PU biopolymer with titanium dioxide (TiO2) nanoparticles. The use of nano-shaped materials in this synthesis has many advantages, including being easier to synthesize and being antibacterial. Meanwhile, starch is the result of isolation from banana weevils, where banana weevils are agricultural waste that has not been utilized properly. Particle size and the use of agricultural waste are a form of modification and innovation in PU synthesis, as well as a novelty in the development of this research. In PU synthesis, several characterization techniques are carried out, including polymer tests, namely strain and stress, functional group analysis using (Fourier Transform Infra-Red), and antibacterial tests. Based on the results of the FTIR test analysis, it show that at a wave number of 1724.36 cm-1, the N-H functional group is visible, and the absorption of urethane and TiO2 groups is in the range of 513.07 cm-1. The mechanical properties test shows the strain (28.92 - 21.88% GL) and young's modulus in the interval (5.484-3.268 MPa). The antibacterial test showed that the inhibitory power of test samples A1 and A4 with diameters of 8 mm and 8 mm proved to be very effective in killing E. Coli bacteria, while test samples A1¹, A2¹, A3¹, and A4 were not able to kill E. Coli bacteria. S. Aureus. bacteria. The characterization results show that PU biopolymer can be used as a basic material for making bacterial decontaminant medical devices.

Entomopathogenic fungi were isolated parasitizing coffee borer beetle (Hypothenemus hampei Ferrari) and banana weevils (Cosmopolites sordidus Germar) in different parts of the island of Puerto Rico to be identified and examined for their pathogenicity on pepper weevil (Anthonomus eugenii Cano). Fungi were isolated and purified in acidulated potato dextroseagar (PDA) in the laboratory of the Plant Disease Clinic at the Agricultural Experiment Station, Juana Díaz. Seven fungal isolates were obtained from the municipality of Comerío, and one from the municipality of Adjuntas. Morphology, DNA sequences of different genetic regions of interest, and microsatellites were used for identification of fungal isolates. Two of the eight isolates were identified as Beauveria bassiana, three as Beauveria caledonica, two as Paecilomyces fumosorosea and one as Paecilomyces lilacinum. Pathogenicity tests were conducted in vitro using conidia suspension (1 x 106 conidia/mL). Insects were inoculated by immersion (10 sec) in the conidia suspension. Daily mortality data was taken (TL50, TL90) and the mean of the treatments were determined. All the fungal species were pathogenic to A. eugenii. The most effective treatments were: P. fumosorosea (Pae1) and B. bassiana (Bb1 & Bb3) with TL50 of 2.39, 2.53 and 2.56 days, respectively, while TL50 for the control was 6.56. A 100% mortality for treatments occurred between the fourth and sixth day compared to control, which reached it in 12 days. These isolates have the potential to be used on an integrated management program for the control of the pepper weevil.

Full textAbstract:
AbstractChlordecone (CD; Kepone™) is a carcinogenic organochlorine insecticide with neurological, reproductive, and developmental toxicity that was widely used in the French West Indies (FWI) from 1973 to 1993 to fight banana weevils. Although CD has not been used there for more than 25 years, it still persists in the environment and has polluted the waterways and soil of current and older banana fields. Today, human exposure to CD in the FWI mainly arises from consuming contaminated foodstuffs. The aims of this study were to develop a physiologically based pharmacokinetic (PBPK) model in the rat and extrapolate it to humans based on available pharmacokinetic data in the literature. A comparison of simulations using the rat model with published experimental datasets showed reasonable predictability for single and repetitive doses, and, thus, it was extrapolated to humans. The human PBPK model, which has seven compartments, is able to simulate the blood concentrations of CD in human populations and estimate the corresponding external dose using the reverse dosimetry approach. The human PBPK model will make it possible to improve quantitative health risk assessments for CD contamination and reassess the current chronic toxicological reference values to protect the FWI population.

Full textAbstract:
This study aimed to assess the level of infestation of plantain bananas by the black weevil <em>Cosmopolites sordidus</em> across three cultivars in the Kisangani region. The cultivars studied were ‘Libanga likale’ (Musa AAB of the false horn type), ‘Litete’ (Musa AAB of the French type), and ‘Lokusu’ (Musa AAB of the true horn type). The study focused on the rate of attack, the average number of adult individuals per plant, and the severity of the attack. The results indicated that all cultivars were susceptible but significantly different from one another regarding the rate of infestation and the number of adult Cosmopolites per infested plant (P < 0.05). The extent of damage varied with the bulb diameter of the infested subjects. The cultivar ‘Litete’ was the most affected, with an infestation rate of 77.5%, hosting an average of 164 adult Cosmopolites per infested plant. Within the same cultivar, plants with a small bulb diameter (16-24 cm) were the most sensitive. These findings suggest that the vigour of the bulb influences the level of infestation of plantain bananas.
