Abstract:

Soybean production in sub-Saharan Africa (SSA) has been increasing in recent years in part due to the efforts of several national and international research agencies, including the Soybean Innovation Laboratory (SIL). SIL’s mission to increase utilization and production of soybean in SSA has led to several facets of research including cultivar development to increase yield through the Pan-African Soybean Variety Trials (PATs). Several abiotic and biotic stresses can decrease yield, including pathogens and pests that attack seed. While evaluating seed lots from 32 PAT locations, we identified bruchids and/or bruchid-damaged seed in nine locations in four countries (Cameroon, Malawi, Mozambique, and Rwanda). The most severe damage and infestation was recorded in Bwanje, Malawi, with 28 of the 40 seed lots infested. Seed damage ranged from 0.6 to 100% among the 28 infested seed lots. Adult bruchids discovered at the Bwanje location were identified as Callosobruchus chinensis, or the Chinese bruchid. No adults were found in other locations. Bruchids are a destructive storage pest of legumes, and monitoring the different species attacking soybean will help researchers and producers understand the potential threat of bruchids to soybean production in SSA as well as help implement the best management practices.

Abstract:

AbstractUscana lariophaga Steffan is an egg parasitoid of bruchid species in West Africa. The hosts are Callosobrucbus maculatus (Fabricius) and Bruchidius atrolineatus Pic, insect pests of stored cowpea. Experiments were carried out to study the selection between hosts of different ages and of different species in choice and no-choice situations. Results were obtained through parasitization studies and by direct behavioural observations. A description of the parasitization behaviour of Uscana lariophaga is given. At 30°C, C. maculatus eggs of 0–2 day old are readily accepted for parasitization, but in a choice situation the 0 day old eggs are preferred. Of the older eggs only those of 3 days old are parasitized but significantly less than those of 0–2 days. At 30°C, B. atrolineatus eggs older than 24 hours are significantly less parasitized than younger eggs also in the no-choice situation. When eggs are older than one day, the time needed for penetrating the egg increases with host age. Both bruchid species are suitable hosts for U. lariophaga. In a choice situation B. atrolineatus is the preferred host and especially so when U. lariophaga has been reared on this species. However, in a no-choice situation the highest rate of successful parasitization is obtained on hosts of the species from which they have been reared. The higher parasitization rate of C. maculatus in the field in Niger can be explained by the difference in the susceptible period between the two host species.

Abstract:

The search for reducing risks associated with the use of chemicals has necessitated use of pest control using plant products. Neem is perhaps one of the most useful medicinal plant in the tropics. Each part of the tree has huge insecticidal property. Apart from the chemistry of the neem compounds, considerable progress has been achieved regarding the biological activity and insecticidal uses of neem. It is now considered as a valuable source of unique natural product for botanical insecticides against various pests. Farmers in tropical countries commonly used its leaves, seed kernels and its oil in various forms. Neem is utilized in form of powders, extracts or as an emulsifiable oil. Researches had shown that neem consists of pesticidal ingredients called triterpenes (limonoids). Trials conducted on the effect of neem products revealed secondary metabolites affect metabolic processes that include feeding and oviposition deterrence; metamorphosis inhibition, protein synthesis, changes in biological fitness, impaired sexual communication and chitin synthesis. Azadirachtin in particular interferes with chemoreception and exerts direct negative effects on many insect tissues such as muscles and digestive epithelial cells as well as insect mortality. Neem derived biopesticides are cheap, available in all ecological zone, posed no hazard to applicator and the environment as it is biodegradable. Insects such as Aphids, African migratory locust, legume pod-borer, coreid bugs and storage insect pests such as cowpea seed bruchid were controlled using neem. Sustainable insect pest control can be achieved with the use of neem based biopesticides.

Abstract:

The over dependence and continues use of synthetic insecticides to control storage pests have been associated with several demerits. This study was conducted to evaluate the insecticidal effect of peppermint (Mentha piperita) leaf powder on Callosobruchus maculatus. The peppermint plant was sourced locally and the C. maculatus were cultured to obtain the adult Bruchids. The peppermint was washed, dried under ambient temperature and pulverized. Complete Randomized Design was adopted for this trial with three replications of six treatment dosages of 2.5, 5.0, 7.5, 10.0, 12.5 and 0.0 g respectively of the plant material. The trial lasted for four weeks. High Bruchids mortality was observed after treatment with Mentha piperita leaf powder extract. Phytochemical screening of the test plant revealed presence of flavonoids, tannins, saponins, carbohydrates and cardiac glycosides. Descriptive statistic and analysis of variance (ANOVA) were used to analyze the data. Means (p≤0.05) were separated using Duncan Multiple Range Test (DMRT). Dosage rate and mean mortality values at the various doses were statistically significant after 48, 72 and 96 hours. The mortality could be attributed to high presence flavonoid in the Mentha piperita leaf powder. The results suggest that the leaf of peppermint has insecticidal property against adult C. maculatus. However, further trials are required to investigate effective dosage rates for other stored grains and to isolate and characterize the active flavonoids contained in the plant.

Abstract:

This work reviews the historical and current pest risks and research concerning seed storage in the Czech Republic (CR). Stored seed pests (i.e. animals causing injuries to the germ and endosperm) represent a high risk of economic damage due to the high value of seeds coupled with long-term seed storage in small storage units (e.g., boxes, satchels). Rodents represent a significant risk to all types of seeds, especially seeds stored in piles or bags. Mites, psocids, and moths are the main pests of stored grass and vegetable seeds: mites can decrease seed germinability by 52% and psocids caused 9.7% seed weight loss in broken wheat kernels after 3 months of infestation under laboratory conditions. Although beetles (Sitophilus sp., Tribolium sp., Oryzaephilus sp.) and moths (Plodia sp.) are common pests of grain seeds (e.g., wheat, barley, maize), two serious seed pests, Sitotroga cereallela and S. zemays, are rare in the CR. Bruchus pisorum is a common pest of pea seeds, while other Bruchids are rare in the Czech legume seed stores. Currently, the control of seed pests is becoming difficult because the efficient pesticides (e.g., methylbromide, dichlorvos, drinking anticoagulant rodent baits) for seed protection have been lost without the development of adequate substitutes. New research on seed protection in the CR using biological control (mite predators Cheyletus sp.), low pressure, modified atmospheres, and hydrogen cyanide is overviewed.

Abstract:

Adzuki bean bruchid (Callosobruchus chinensis) is a significant pest of soybean in Uganda. To sustainably manage this pest, utilization of resistant soybean varieties is the key solution. Development of resistant varieties needs knowledge on modes of inheritance which is crucial in selection of parent materials. To identify parents, a study was initiated to determine the gene action and mode of inheritance of resistance to bruchids in soybean. Nine parental lines were crossed in a full-diallel at Makerere University Agricultural Institute, Uganda. The generated F1s were advanced to F2 and seeds were evaluated for response to bruchid infestation in a randomised complete block design. Ten seeds were infested with 10 randomly selected unsexed 1-3 day old bruchids. Genotypes showed significant differences in seed weight loss (swl), adult bruchid emergence (ABE) and Dobie susceptibility index (DSI) indicating that these parameters could be used to screen genotypes in genetic analysis. Mean squares of general combining ability (GCA) were significant (P < 0.05) for swl, DSI and number of ABE from the F2 seeds indicating additive gene action. Susceptibility parameters ABE and DSI showed significant specific combining ability (SCA) indicating non-additive gene action. Resistance was influenced by maternal effects indicating that direction of the cross was important. Genotypes S-Line 9.2 and S-Line 13.2A showed negative significant GCA effects for at least two of the susceptibility parameters indicating that they were the best parents for bruchid resistance breeding. The study established that additive, non additive and maternal effects governed the gene expression in soybean resistance to bruchids.

Abstract:

Stored-product pests in the family Bruchidae of Coleoptera represent important pests affecting legume seeds. The lentil weevil, Bruchus lentis Froelich (Coleoptera: Chrysomelidae: Bruchinae) is one of the major lentil pests in Iran and in the world. The economic losses caused by this pest on lentil grow up to 40%. Synthetic pesticides are currently the chosen method to protect stored grain from insect damage. However, their widespread use has led to the development of pest strains resistant to insecticides and pest resurgence. In recent years, nonchemical methods, including biological agents are considered safe methods to control the stored grain pests. Positive characteristics of entomopathogenic nematodes as biological control factors of arthropod pests, introduce them as an appropriate option for controlling the integrated pest management of lentil weevil. In the present study, an isolate of entomopathogenic nematode, Steinernema feltiae, isolated from soils around Yasouj and based on morphological traits and morphometric data were identified. Adult insects of lentil weevil were exposed to concentrations of 0; 500; 1,000; 2,000 and 3,000 infective juvenile/ml of distilled water at different temperatures (20, 23, 26 and 29 °C). Insects were placed on filter paper impregnated with 1 ml of nematode suspension in Petri dishes for three days. Mortality of the insects was recorded every 24 hours. The highest mortality was recorded after 72 hours, which represented 79.40%, at the concentration of 3,000 infective juvenile at 26 °C.

Abstract:

AbstractDry grain legume seeds possessing αAI-1, an α-amylase inhibitor from common bean (Phaseolus vulgaris), under the control of a cotyledon-specific promoter have been shown to be highly resistant to several important bruchid pest species. One transgenic chickpea and four cowpea lines expressing αAI-1, their respective controls, as well as nine conventional chickpea cultivars were assessed for their resistance to the bruchids Acanthoscelides obtectus (Say), Callosobruchus chinensis L. and Callosobruchus maculatus F. All transgenic lines were highly resistant to both Callosobruchus species. A. obtectus, known to be tolerant to αAI-1, was able to develop in all transgenic lines. While the cotyledons of all non-transgenic cultivars were highly susceptible to all bruchids, C. chinensis and C. maculatus larvae suffered from significantly increased mortality rates inside transgenic seeds. The main factor responsible for the partial resistance in the non-transgenic cultivars was deduced to reside in the seed coat. The αAI-1 present in seeds of transgenic chickpea and cowpea lines significantly increases their resistance to two important bruchid pest species (C. chinensis and C. maculatus) essentially to immunity. To control αAI-1 tolerant bruchid species such as A. obtectus and to avoid the development of resistance to αAI-1, varieties carrying this transgene should be protected with additional control measures.

Abstract:

The use of bio-pesticides has proven to be successful approach in controlling agricultural insect pests. Study was conducted in the Laboratory of the Department of Crop Protection, Faculty of Agriculture, Bayero University, Kano to study the Biology of Bruchus baudni on treated Senegalia senegal seeds. Seed oils and leaf powders of K. senegalensis and M. oleifera at three concentrations each, a chemical insecticide (Aluminum phosphide as standard check) and a control were laid out in a Completely Randomized Design (CRD) and replicated three times. Data collected were oviposition, egg hatchability and developmental stages. The results indicated significant reduction in the number of eggs laid (1% and 1.38%) and hatchability (0.00% and 0.57%) on both seed oil and leaf powder treatments, respectively; however, the control recorded the highest eggs laid (99.9%) and number of emerged B. baudni (99.2%). The present findings showed that seeds and leaves of mahogany and moringa were effective as protectant against some of the development stages of B. baudni. Therefore, based on the present results, mahogany and moringa seeds and leaves could be explored to replace the synthetic insecticides in the management of B. baudni especially as components of integrated pest management strategy.

AbstractSouth American Trichogrammatidae are poorly known. In this paper we describe a new species of Trichogramma and two new species of Uscana from Chile. The Trichogramma species belongs to the perkinsi group and parasitizes the eggs of Rhyacionia buoliana (Lepidoptera: Tortricidae). One Uscana species belongs to the senex group (new name proposed for the B group) and parasitizes eggs of Pseudopachymerina spinipes (Coleoptera: Bruchidae), and the other Uscana species belongs to the fumipennis group (new name proposed for the C group) and parasitizes eggs of Bruchus pisorum (Coleoptera: Bruchidae). These new species might be useful in biological control, especially against R. buoliana and B. pisorum, important pests of pines and peas, respectively, in Chile.

Oviposition Deterrence of Bean Weevil, Callosobruchus chinensis L.(Coleoptera: Bruchidae) Treated with Ten Plant Extracts. Pest and Diseases attack agricultural products not only in the field but also in storehouse. Their attack causes decreasing both quantity and quality of stored materials. One of important stored product insect pests is Callosobruchus chinensis L. (Coleoptera: Bruchidae). Till now the effective strategy to control this insect pest is chemical control by using synthetic insecticides. The improper use synthetic insecticides causes some undesirable effects, so alternative strategist should be searched to controls insect pests in storehouse. One of the alternatives is by using plant materials as insect pests control agent. The aim of this study was to find out the oviposition deterrence of C. chinensis treated with ten plant which were extracted with methanol, hexane and ether. Oviposition deterrence was evaluated by choice and no-choice methods at 1,3 and 5% of extract concentration. Extract of Acorus calamus (methanol), A.calamus (hexane), A. calamus (ether), Illicium verum (ether), Pogostemon calbin (hexane), P. cablin (ether), Vetiveria zizanioides (hexane), and V. zizanioides (ether) were able to deter ovipostion activity of C. chinensis by more than 90% of deterrence. Further study should be conducted to isolate and identify the active compound and to make botanical insecticide formulation for practical use as a commercial product.

Abstract:

AbstractA number of insect species infest human households and stored foods and products, leading to their designation as pests. Until recently, little was known about the factors driving the evolution of pests that feed on stored dry foods. Here, I review the effects of changes in climate and species interactions on the evolution and ecology of beetles that feed on dried seeds/grains. My review focuses on evidence that the host utilization by part of the species in the subfamily Bruchinae (Chrysomelidae) is a preadaptation for utilizing stored dry seeds and grains, thus leading to their status as a pest. These and other stored product pest beetles retain a higher percentage of water in their body, relative to the water content of their diet, than beetles that feed on fresh crops. I review the studies that have documented adaptation, acclimation and polyphenetic response to high temperatures and desiccation and/or made direct comparisons between these traits between developmental stages, populations and among higher taxonomic groups. Finally, I review evidence for the effects of environmental change on insect host-parasitoid and competitor assemblages.

Abstract:

Survey were undertaken in five zones of Oromiya and Amhara regional states, Ethiopia from February to March 2018 to investigate farmers’ status, knowledge, major chickpea production constraints and insect pest management practices of chickpea. The survey involved 293 randomly taken farmers, who are interviewed using a semi-structured questionnaire. Chickpea insect pests were considered as the main, among production constraints of chickpea by most of the interviewed farmers in Ethiopia. The majority of the farmers’ responded that Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is the most prevalent insect pests of chickpea under field condition and Callosobruchus chinensis (L.) (Coleoptera: Bruchidae) in storage. Development Agents (DAs) were the top pest advisory service providers in the current study. A conventional insecticide (namely; Lambda-cyhalotrin and Dimethoate) for the control of H. armigera was the most commonly used pest management methods. Moreover, Two times insecticide applications per cropping season were the most frequent, deployed by most of the interviewed farmers followed by cultural pest management practices. Use of biological control and resistant chickpea varieties against major insect pests were low to negligible in the current survey study in the area. The majority of the farmers began control decision when H. armigera larval stages were smaller and they did not consider larval number per chickpea plant for the decision. These results will be used to formulate future effective and sustainable integrated pest management (IPM) in chickpea for Ethiopian farmers emphasizing ecologically and economically-based approaches.

We have confirmed here that the seeds of the common bean (Phaseolus vulgaris, L.) do not support development of the bruchid Callosobruchus maculatus (F.), a pest of cowpea [Vigna unguiculata (L.) Walp] seeds. Analysis of the testa (seed coat) of the bean suggested that neither thickness nor the levels of compounds such as tannic acid, tannins, or HCN are important for the resistance. On the other hand, we have found that phaseolin (vicilin-like 7S storage globulin), detected in the testa by Western blotting and N-terminal amino acid sequencing, is detrimental to the development of C. maculatus. As for the case of other previously studied legume seeds (Canavalia ensiformis and Phaseolus lunatus) we suggest that the presence of vicilin-like proteins in the testa of P. vulgaris may have had a significant role in the evolutionary adaptation of bruchids to the seeds of leguminous plants.

Abstract:

Abstract Essential oil from Allium sativum was isolated and investigated for its repellent, insecticidal, ovipositional and egg hatching inhibition activities against pulse beetle, Callosobruchus chinensis (Coleoptera: Bruchidae). A. sativum essential oil repelled bruchid adults at a very low concentration in choice oviposition assay. A. sativum essential oil caused both fumigant and contact toxicity in C. chinensis adults in a concentration dependent manner. Oviposition potency of C. chinensis adults was reduced significantly when sublethal concentrations of A. sativum essential oil were applied by fumigation and contact method. In chronic toxic-ity assay, A. sativum essential oil reduced F1 progeny emergence, damage and weight loss in seeds. Findings of the present study suggest that A. sativum essential oil can be useful as promising agent in insect pest management programme.

Abstract:

The adzuki bean weevil Callosobruchus chinensis is the main pest of mungbean especially during seed storage. Mungbean generally has low yield and is susceptible to main pests. Ricebean (Vigna umbellata (Thunb.) Ohwi & Ohashi) has superior characters such as the high pod number per plant and resistance to many pests. The interspecific hybridization was conducted to combine the superior characters of mungbean and ricebean. The objectives of this research were to evaluate resistance of hybrids of interspecific hybridization between mungbean and ricebean to C. chinensis and to determine pattern of resistant inheritance. Evaluation of resistance to this pest was conducted in bottles by placing 200 hybrid seeds and then 20 C. chinensis adults were introduced into the bottle covered by dense cheese cloth. The bottles were arranged in a completely ramdomized design with three replications. The treatment consisted of eight hybrids and six parents. The results showed that the resistance of the test hybrids to C. chinensis was different among cross combinations. Hybrids of crossing between mungbean Merak variety and yellow ricebean as well as Vima variety and red ricebean were moderately resistant, while the others were resistant. There was resistance improvement of hybrids to C. chinensis. The resistance of the hybrids to C. chinensis was controlled by single gene with partially dominance gene action.

AbstractDevelopment and reproductive success of the solitary egg parasitoid Uscana lariophaga Steffan were examined after development in eggs of the bruchid storage pest Callosobruchus maculatus Fabricius reared at either low or high densities on cowpea seeds and laid at day 1 and 4 of maternal life. Both bruchid larval competition and maternal age negatively affected egg size, but the latter more than the former. Uscana lariophaga reared in small hosts developed slower, were smaller and produced fewer eggs compared to parasitoids reared in large hosts. Fecundity of the parasitoid was heavily influenced by host egg size. This was reflected in the values for the intrinsic rate of increase of U. lariophaga, which differed for wasps that developed in host eggs laid by bruchid females of different age. Wasps allocated marginally more female offspring to larger hosts.

Abstract:

Storage pests remain one of the main problems in storage. The pest attacks occur not only in the field, but also in storage. Control should be done to maintain the quality of storedproducts. The environmentally friendly measures should be implemented to avoid negative impacts to the environment and human being. The objective of this research was to study the mortality and oviposition deterrence caused by powder and oil of six plant species against Callosobruchus sp. (Coleoptera: Bruchidae). Flowers of Eugenia aromatica, roots of Vetiveria zizanioides, leaves of Pogostemon cablin, seeds of Ricinus communis, seeds of Foeniculum vulgare, and stems of Cymbopogon citratus were air-dried and milled to yield powder. Oil of six plant species were purchased from local market. Oviposition deterrent bioassay was conducted by no-choice method for both powder and oil, while mortality bioassay was conducted by topical application and residual methods for plant oil only. Several plant species showed high biological activity to Callosobruchus sp. Powder of E. aromatica and oil of V. zizanioides caused high oviposition deterrence, while oil of V. zizanioides and E. aromatica caused high mortality.

Abstract:

AbstractBruchid pests such as Callosobruchus chinensis (Linnaeus) endanger stored legume seeds throughout the tropical belt. The chemical composition of the headspace volatiles from healthy and fourth instar larvae-infested cowpea seeds were identified, characterized, and compared using gas chromatography–mass spectrometry. Y-tube olfactometer bioassays were performed to evaluate the effect of these chemicals on the orientation of conspecific adult females. Analysis of volatiles released from healthy and infested seeds revealed qualitative differences for three out of the 17 compounds identified. Dimethyl disulphide, isobutenyl methyl ketone and methyl trisulphide were found only in the blend emitted from infested but not from healthy seeds. Quantitative differences were apparent for tridecane which was released in larger amounts from infested seeds. While volatiles collected from healthy seeds were attractive to female bruchids, volatiles collected from infested seeds were repellent. To test the hypothesis that the qualitative differences in the chemical composition found may be due to insect-derived components, the volatiles from frass and fourth instar larvae combined were analysed. These volatiles contained both of the sulphides emitted from infested seed but not from healthy seeds. Although a limited induction of volatiles from cowpea seeds cannot be excluded, it is postulated that behavioural differences of the female weevils are largely due to insect-derived semiochemicals. The potential use of such semiochemicals as part of an integrated pest management strategy is discussed.

Abstract:

Pea (Pisum sativum L.) is an important leguminous plant worldwide, in which pests trigger significant damage every year. One of the most important pest is pea weevil (Bruchus pisorum, L) which causes covert damage in crops. In the present study, our aim was to obtain precise information pertaining to the extent and the nature of damage in pea caused by B. pisorum by means of non-invasive imaging methods. The infested pea samples were analysed by an infrared thermometer and a bioluminescence plant imaging system as well as a computer tomograph under laboratory conditions. The calculated weight of organic matter destroyed by the developing larvae was 36.46%. The changing of RGB (red, blue, green) codes obtained through thermal imaging and the CPS (counts per second) values originating from bioluminescence imaging in infested samples were statistically verifiable. According to our CT assay, the damage caused by B. pisorum changed the tissue density, volume and shape of the pea seeds by the end of the development of the pest. The results of thermal and bioluminescence imaging contribute to a better understanding of the internal chemical processes and the CT analysis helps to understand the alteration trends of the inner structure of seeds caused by this pest.

Abstract:

Callosobruchus chinensis is one of the major insect pest of chickpea and other stored legume which is known to cause significant yield loss both quantitatively and qualitatively. This investigation was done to study the efficacy of leaf powders of basil (Ocimu basilica L.) and neem (Azadirachta indica), cow dung ash and Malathion dust against bruchid on two chickpea varieties namely Desi (local) and Habru (improved Kabuli). Levels of infestation, weight loss, germination capacity (delete) and germination of the seeds were evaluated monthly up to six months. In the bruchid infested treatment (control), hundred seeds weight, seed germination decreased through time while levels of infestation and weight loss increased. All the tested locally available treatments (cow dung ash, leaf powder of neem and leaf powder of basil) were found to be effective in reducing the damage inflicted by bruchid compared to the control. Malathion dust was observed to be the most effective of all treatment in this study. However, looking in to the side effects of synthetic pesticides, we suggest that the locally available plant powders and cow dung ash which is cheap, ecologically friendly and non-hazardous to human health can play an important role in protection of chickpea during storage against invasion by bruchid.

Abstract:

Pea (Pisum sativum L.) is a valuable grain legume crop, the seeds of which are used for human food and fodder. The seeds are consumed in a mature or green state. The priorities of the peas as a crop are the following: it is a legume, which enriches the soil with nitrogen; peas are the best possible precursor - clears the areas early; non-particular to soil and growing conditions; high protein content crop. However, the growing process of this crop could be worse by various pests that lead to product quality decay or they could even destroy the pea production. Economically important pests in field cultivation of peas are: pea aphid (Acyrthosyphon pisum Harris), pea weevil (Bruchus pisi L.) and pea moths (Laspeyresia nigricana Step. and Laspeyresia dorsana L.). Field experiments on pea variety Paldin were conducted at the Maritsa Vegetable Crops Research Institute, Plovdiv to determine the effectiveness of different plant protection products against a natural background of pest infestation. The biological activity of the insecticides Deca EC 50 ml/da (a. i. deltamethrin), Oasis 5 EC 25 ml/da (a. i. esfenvalerate), Piretro Natura 75 ml/da (a. i. pyrethrins), Neem Azal T/C 0.3% (a. i. azadirachtin), Naturalis 100 ml/da (a. i.

Abstract:

Adverse effects caused by synthetic pesticides have increased interest in plant-derived insecticidal compounds, in particular essential oils, as a more compatible and ecofriendly alternative for pest control of economic importance. For this reason, the essential oil isolated from leaves and shoots of Drimys winteri (J.R. Forster & G. Forster)—also named canelo (CEO)—was investigated for its chemical profile and insecticidal action against Acanthoscelides obtectus (Say)—one of the most important post-harvest pests of dry beans in the world—and Aegorhinus superciliosus (Guérin)—a significant pest of fruit trees in Chile. The analysis by gas chromatography, paired with mass spectrometry (GC/MS) determined 56 compounds, corresponding to 92.28% of the detected compounds. Elemol (13.54%), γ-eudesmol (11.42%), β-eudesmol (8.49%), α-eudesmol (6.39%), α-pinene (7.92%) and β-pinene (5.17%) were the most abundant. Regarding the bioactivity of the CEO, the results demonstrated toxicological effects against A. obtectus. A concentration of 158.3 µL L−1 had a mortality rate of 94% after 24 h exposure. The LC50 and LC90 values at 24 h were 60.1 and 163.0 µL L−1. Moreover, behavioral bioassays showed a repellent effect against A. superciliosus with a dose of one microliter of CEO. Both sexes of the raspberry weevil stayed for very short times in the treated area with the oil (<0.8 min), showing a homogeneous repellency in the species. The overall data suggest that canelo leaves and shoots essential oil has an insecticide effect and is worth exploring to better understand the synergistic relationship between the compounds present in the essential oil.

Callosobruchus maculatus (F.) is a very serious pest of cow pea in storage in Nigeria and many other oountries (Singh, 1977; Tindall, 1983). Damaged seeds are riddled with emergence holes, defaced with egg covers and have reduced viability. Heavy attack causes severe powdering and weight loss. In Nigeria, about 30–60% loss in cow pea is attributed to infestation and damage by bruchid beetles over a 3- to 6-month storage period, of which over 90% is caused by C. maculatus alone (Caswell, 1981).

Abstract Dioscorea sansibarensis bulbils are well known for their toxicity and medicinal applications. In this study, the attraction and mortality of the Phaseolus vulgaris weevil (Bruchus chinensis) caused by Dioscorea sansibarensis bulbil oil was examined in a Completely Randomized Design experiment using a Y-tube olfactometer on a laboratory bench. Statistical analysis at P < 0.05 showed 10 µL had an attraction of 42.67%. In the case of mortality, the results showed that Phaseolus vulgaris seeds treated with 40 µL of the bulbil oil had a harmonic mean of 55.8% mortality of the weevil population, which was higher than with 10 µL of Actellic 50 EC. GC-MS analysis identified 17 compounds in the bulbil oil, the main constituents of which were 2- pentanone, 4-hydroxy-4-methyl- (17.8%), phenol, 4-ethyl- (11.41%), hexadecanoic acid, methyl ester (11.05%), phenol (7.35%), 9-octadecenoic acid, (E)- (7.2%) and phenol, 4-ethyl-2-methoxy- (7.14%). Attraction by bulbil oil may have been due to the presence of phenolic compounds, and mortality may have been due to hexadecanoic acid, methyl ester and 9-octadecenoic acid, (E)-. Attractants are used for the surveillance and detection of an infestation in stored products. The added advantage of the bulbil oil to cause mortality makes Dioscorea sansibarensis bulbil oil useful in the formulation of a botanical pesticide in stored pest management.

Abstract:

ABSTRACT Bean weevil [Acanthoscelides obtectus Say (Coleoptera: Bruchidae)] is considered the main storage pest of the bean crop. Its control is performed mainly by chemical treatment, which has potential to cause resistance in pests, as well as environmental contamination. This study aimed at evaluating the insecticidal and repellent effect of Salvia officinalis L. essential oil against bean weevil. The doses used for the insecticidal test were: 0 L t-1, 0.5 L t-1, 1.0 L t-1, 1.5 L t-1, 2.5 L t-1 and 5.0 L t-1 of bean grains. For the mortality test, the experimental design was completely randomized, in a 6 × 7 (dose × time) factorial scheme, with five replications. The number of dead insects was counted at 2, 6, 12, 24, 48, 72 and 96 h after the insect introduction. The repellency test was conducted in arenas, under a completely randomized design, using the same doses applied to evaluate the insecticidal effect. Counts were performed 24 h after the introduction of insects. The insecticidal effect of the S. officinalis essential oil on A. obtectus resulted in mortality rates higher than 95 %, after 6 h of insect introduction, for all doses tested. Repellency effect was also detected for all doses tested.

Two types of pea seeds were observed: apparently healthy seeds and seeds damaged by the activity of a weevil (Coleoptera, Bruchidae). At least two-fifths of all finds have apparently been infested most probably by pea weevil (Bruchus pisorum L.), one of the most important pea pests worldwide, especially in medium-moist and dry climates, such as Southern Europe and Australia. A large amount of infested pea seeds indicates a developed pea production on small plots, strongly indicating that cultivating this ancient pulse crop must have been well-rooted in field conditions. Previous DNA analyses of charred pea placed the ancient Hissar pea at an intermediate position between extantly cultivated pea (P. sativum L. subsp. sativum var. sativum) and a wild, winter hardy, 'tall' pea (P. sativum subsp. elatius (Steven ex M. Bieb.) Asch. et Graebn.). Based on an assumption of its late harvest time and combined with pea weevil life cycle stage in charred seeds, it was possible to estimate the season during which the seeds were carbonized, namely, the second half of July or the first days of August at the latest. Older, final weevil instars were predominant before seed carbonization. The pea infestation rate at Hissar is one of the highest noted among pulses in the Old World and the highest among peas, so far.
