Abstract:
The process of palm oil culture is influenced by various factors, one of which is the pest and disease factors. Generally the problem of farmers differentiating pests and diseases, this is dyed most of the farmers lack information and rely on the experience of other farmers to overcome the existing pest and disease problems. In handling pests and diseases, it is necessary to have a farmer consilant who is able to diagnose pests and diseases on oil palm trees. In this study, an expert system for diagnosing pests and diseases in palm tree plants, as well as providing various solutions for pests or diseases. The method used in this expert system is the Certainty Fators method. Certainty Method The factors was chosen because this method is suitable in the process of determining the identification of pests and diseases and the result of this application is the percentage of the system. The percentage is influenced by the CF value obtained from the system, the percentage of expert system consultations is taken from the highest yield as an alternative to other pests or diseases that attack oil palm tree crops.

Abstract:
Parasitoids play an important role in controlling pests, including pests of oil palm. To maximize biological control technique using parasitoids, interactions between pests and parasitoids need to be studied. This research aimed to study parasitoid diversity and host-parasitoid interaction in oil palm plantation with the different management system. The field research was conducted in oil palm plantation own by smallholder and company (PT Humusindo) in Jambi. Sampling insects was conducted by collecting pests (parasitoid host) on oil palm trees with age of four years old. Eggs, larvae, and pupae of the pests were taken directly by hand then reared in the laboratory to know their parasitoids. Pests and parasitoids emerged were identified up to morphospecies or species level. A total of 176 lepidopteran pests consisting of 15 morphospecies and 6 families, and 650 parasitoids consisting of 21 morphospecies and 12 families have been collected. Nine morphospecies of pests from 25 individuals were found in smallholder plantation and 14 morphospecies of pests from 151 individuals in company plantation. Eight morphospecies of 26 parasitoids were found in smallholder plantations and 8 morphospecies of 624 parasitoids in the company plantation. The interaction structure between pests and parasitoids is more complex in the company plantation than in smallholder plantations. Family Braconidae and Ichneumonidae are the most parasitoids found and associated with nettle caterpillars. The different of the management system of oil palm plantation did not affect the diversity and abundance of pests as well as their parasitoids in oil palm plantations.

Abstract:
The natural habitat of the oil palm comprises very wet and relatively dry niches in the lowland rain forest in West and Central Africa. The domestication of the oil palm started with the extraction of fruits from wild forest resources. When forests were cleared for shifting cultivation, oil palms were not felled and in the subsequent regeneration period they obtained a favourable position resulting in semi-wild palm groves. Thinning of groves gave rise to semi-permanent or permanent intercropping systems of palms and food crops. After the transfer of oil palm to SE Asia in the 19th century, a mono-crop oil palm evolved. Its success was based on a favourable climate, breeding, improved cultivation and processing practices and the absence of major pests and diseases. The high-yielding production systems are sustainable at high input levels and pollution can be kept within acceptable limits. Oil yields and production costs compare favourably to those from other oil crops. The domestication of oil palm for oil yield so far can be considered as a success story. Physiological studies indicate that there is still considerable scope for further increase in yield. The adaptation of oil palm to new environments will continue and produce diversification puts new demands on domestication. This paper reviews the different stages in the domestication process especially adaptation to plantation agriculture, the simultaneous genetic improvement, and the prospects of reaching full yield potential in different environments.

Abstract:
Ants are social insects which widespread and play many important roles in an ecosystem. Myopopone castanea ants are a predator for the pre-adult stage of pest Oryctes rhinoceros which is one of the important pests in oil palm plantations. At the oil palm plantations, M. castanea and pre-mature stadia from pests O. rhinoceros live on decaying palm oil stems. This study aimed to explore the presence and the microhabitat characteristics of M. castanea ant in oil palm plantation so that mass rearing of M. castanea ants can be carried out in the laboratory to support the natural enemy augmentation program in biological control of O. rhinoceros pest. The exploration of ant nests was carried out in two plantation locations: smallholder oil palm plantations in Tanah Merah sub-district, Binjai Selatan Subdistrict, Binjai and PTPN 2 and PTPN 4 in Deli Serdang and Serdang Bedagai districts, North Sumatra Province. The results showed that the colonies of M. castanea in both of plantations vary greatly in the size of the number and stage of the ant development stage. Average of abiotic factors in the microhabitat of M. castanea ants in PTPN plantation (t = 29.7 0C, Rh = 70%, pH = 6.03 and C / N ratio = 66.18%), while for smallholder plantation (t = 29.1 0C, Rh = 70.9%, pH = 6.39 and C / N ratio = 69.01%). A suitable abiotic environment will support life and mass rearing of M. castanea ant colonies.

Abstract:
Jambi Province is a producer of palm oil as a mainstay of commodities. However, the limited insight of farmers in Jambi to oil palm pests and diseases affects oil palm productivity. Meanwhile, knowing the types of pests and diseases in oil palm requires an expert, but access restrictions are a problem. This study offers a diagnosis of oil palm disease using the most popular concept in the field of artificial intelligence today. This method is deep learning. Various recent studies using CNN, say the results of image recognition accuracy are very good. The data used in this study came from oil palm image data from the Jambi Provincial Plantation Office. After the oil palm disease image data is trained, the training data model will be stored for the process of testing the oil palm disease diagnosis. The test evaluation is stored as a configuration matrix. So that it can be assessed how successful the system is to diagnose diseases in oil palm plants. From the testing, there were 2490 images of oil palm labeled with 11 disease categories. The highest accuracy results were 0.89 and the lowest was 0.83, and the average accuracy was 0.87. This shows that the results of the classification of oil palm images with CNN are quite good. These results can indicate the development of an automatic and mobile oil palm disease classification system to help farmers.

Abstract:
Three field experiments were conducted to find out the efficacy of neem products against the damage of rhinoceros beetle to coconut palm and termite damage to coconut palm and plaited leaves. The application of cither neem seed powder + sand (1:2) or neem seed kernel powder + sand (1:2) @ 150 g mixture per palm in the bases of three leaf axils in the crown, were found more effective against rhinoceros damage. Spraying of neem oil 5% or neem seed kernel extract 20% from the base and up to, 2 m height on the truck protected the palm from termites. Spraying with copper sulphate 1% and‑then neem oil 5% or copper sulphate 1% and then neem seed kernel extract 20% on plaited coconut leaves was found efficacious in protecting plaited coconut leaves for more than six months even when the plaited leaves were kept on the bare ground having persistent live termite colony throughout the year.

Abstract:
The leaf miner (Coelaenomenodera elaeidis) is a major pest of the oil palm. It breaks out in epidemic proportions periodically, resulting in severe leaf defoliation and consequently low fresh fruit bunch (FFA) yield. This study analyses temperature, rainfall, relative humidity, and leaf miner abundance records sampled in oil palm fields between 1976 and 1980 in the main station of the Nigerian Institute for Oil Palm Research (NIFOR). Data for temperature, rainfall, and relative humidity were obtained from NIFOR meteorological station. Mathematical relationships between the insect stages (larva, pupa, and adult) and weather factors (rainfall and temperature) were developed indicating that pest predictions can be made for different leaf miner stages using their corresponding model equations giving specific values for rainfall and temperature. Variations in the seasonal patterns of temperature and rainfall are of major significance as a cue to timing leaf miner abundance and would help in making better decisions regarding where farmer action can target pest control interventions, thereby contributing to ensure food security. The need for continuous monitoring has great potential for detection and control of insect pests in oil palm growing areas.

O óleo de palma destaca-se por ser a principal fonte alimentícia de óleo vegetal liderando a produção mundial seguido da soja. Devido à escassez de estudos básicos para manejo de desfolhadores em palma de óleo, este trabalho objetivou avaliar a resposta fisiológica das plantas sob desfolha e efeito da desfolha na produção, bem como determinar o nível de dano econômico. Esse trabalho mostrou que a injúria artificial com tesoura e natural por lagartas de B. sophorae não resultou em efeitos no processo fisiológico das folhas remanescentes em mudas de híbrido interespecífico (Elaeis guineensis Jacq. X Elaeis oleifera [Kunth, Cortés]) e, provavelmente, as plantas responderam com mecanismos compensatórios evitando assim interromper seus processos fisiológicos evitando a perda de água, mantendo seu processo autotrófico nos tecidos remanescentes. Os resultados mostraram ainda que a desfolha ocasionada pelas lagartas e a mecânica não apresentaram diferenças e que injúrias mecânicas podem ser usadas em estudos de desfolha simulada. Com isso, justificou-se o uso de desfolha artificial para estudar seu efeito sobre a produção. Paralelamente, obteve-se o consumo de área foliar total para larvas de Opsiphanes invirae Hübner, que foi de 286,064 cm2. O nível de dano econômico foi 5,14 e 2,98 lagartas por folha utilizando o produto Dipel® WP e SC, respectivamente para dados de perdas acumuladas em dois anos. Considerando apenas a injúria artificial obtida nas condições da Agropalma, o NDE utilizando Dipel® WP e SC foi de 3,72 e 2,15 lagartas por folha, respectivamente. Os valores atualmente adotados empiricamente para tomada de decisão pelas empresas são superiores aos valores encontrados nesse estudo, mostrando que devem ser revistos.
Palm oil is notable for being the main food source of vegetable oil leading the world production followed by soybeans. Due to the shortage of basic studies for management of palm oil defoliators, this study aimed to evaluate the physiological response of plants under defoliation and effect of defoliation on the production, as well as to determine economic injury level. This work showed that the artificial injury using scissors and natural using B. sophorae larvae did not result in effects to the physiological process of the remaining leaves in interspecific hybrid seedlings (Elaeis guineensis Jacq. X Elaeis oleifera [Kunth, Cortés]) and, probably, the plants responded with compensatory mechanisms avoiding interruption of the physiological processes preventing the loss of water, keeping the autotrophic process in the remaining tissues. The results also showed that the defoliation either caused by the larvae or by scissors did not show differences and mechanical injuries can be used in simulated defoliation studies. Thus, this justified the use of artificial defoliation to study its effect on production. At the same time, the consumption of total leaf area was obtained for Opsiphanes invirae Hübner larvae, which was 286.064 cm2 and the level of economic damage to this species in oil palm. The economic injury level was 5.14 and 2.98 larvae per leaf using the product Dipel® WP and SC, respectively, using two-year loss data. Considering only the artificial injury obtained at Agropalma, the economic injury level using Dipel® WP and SC was 3.72 and 2.15 larvae per leaf, respectively. The current values empirically adopted for decision making by companies are higher than the values found in this study, showing that they must be reviewed.

Abstract:
La lutte contre les rongeurs est souvent un enjeu majeur dans les agroécosystèmes. Nous avons conduit une étude comparative dans des plantations de palmiers à huile dans les provinces de Riau et de Bangka en Indonésie. Dans les deux zones, des chouettes ont été introduites pour la lutte contre les rats ; toutefois, à Riau les rats sont maintenus à des niveaux de population acceptables sans recours au raticide, tandis qu’à Bangka les dégâts des rats sont très importants et l’usage de raticide intensif. Nous avons comparé ce deux systèmes en terme d’abondance et/ou de régime alimentaire de deux prédateurs, chouettes et petits carnivores. D’après nos résultats, les petits carnivores sont beaucoup plus abondants dans les plantations à Riau qu’à Bangka, et le chat léopard (Prionailurus bengalensis) est absent à Bangka tandis que cette espèce domine à Riau. Nos résultats suggèrent également que la prédation sur les rats par les chouettes et les petits carnivores serait moindre à Bangka qu’à Riau. D’une manière générale, cette étude confirme l’hypothèse selon laquelle les petits carnivores, notamment les chats léopard, joueraient un rôle important dans la lutte contre les rats en palmeraies. Par ailleurs, nous avons analysé la distribution spatiale des petits carnivores en plantation. Nos résultats suggèrent que, bien que l’habitat palmeraie soit largement utilisé la nuit par certains petits carnivores comme le chat leopard, qui y trouve une abondante ressource alimentaire, la plupart des espèces sont dépendantes de la forêt. Les gestionnaires des palmeraies devraient adapter leurs pratiques, afin de favoriser les petits carnivores dans une perspective de lutte contre les rats
Rodent pest control is often a major issue in agroecosystems. We conducted a 3-year comparative study (2010-2012) in oil palm plantations in Riau and Bangka provinces, in Indonesia: in both areas barn owls have been introduced for rat control, and were at least as abundant in Bangka plantations than in Riau, but in Riau rat populations have been maintained at an acceptable level without the use of rodenticide, whereas in Bangka intensive rodenticide applications did not prevent high levels of rat damage. We compared these two contrasting systems in terms of predator community (barn owls and small carnivores) abundance and/or diet. We found that small carnivores were much more abundant in Riau plantations than in Bangka, and that the leopard cat (Prionailurus bengalensis) was the dominant species in Riau while absent from Bangka. Our results on diet suggested that rat prey intake from barn owls and from the small carnivore community would be less in Bangka plantations than in Riau. Broadly, our results suggest that small carnivores, notably the leopard cat, play an important role in rodent control. In addition, we investigated spatial distribution of small carnivores within the oil palm habitat. Our results support the hypothesis that, although the oil palm may be habitable for some small carnivore species such as the leopard cat, where they supposedly forage at night, most species still need forest for their survival in oil palm landscapes. Oil palm plantations managers should adapt agricultural practices and land-use to enhance small carnivores, with the view to improve rodent control

A presente pesquisa teve por objetivos estabelecer uma metodologia para criação de O. invirae e identificar genótipos de palma de óleo que apresentem fontes de resistência a esse inseto, nas categorias por não preferência para alimentação, antibiose e tolerância, sendo esta última baseada na produtividade após simulação de desfolha nas plantas. Os experimentos foram conduzidos em laboratório, exceto o teste de tolerância, o qual foi em condições de campo. Para a metodologia de criação, as lagartas foram criadas individualmente em placas de Petri até o quarto ínstar e posteriormente transferidas para recipientes maiores onde permaneceram até a emergência dos adultos. Foram utilizados 5 genótipos de palma de óleo para os testes de não preferência para alimentação, antibiose e tolerância, quais sejam: Deli x LaMe tratamento testemunha, Compacta x Ekona; Deli x Ekona; Compacta x Nigéria e Compacta x Ghana. Os testes com e sem chance de escolha, foram realizados com lagartas de O. invirae recém-eclodidas e com 12 dias de idade. Foram avaliados o consumo e a atratividade a 1, 3, 5, 10, 15 e 30 minutos e 1, 2, 6, 12, 24, 48 e 72 horas, após a liberação dos insetos. No teste de antibiose, as lagartas de O. invirae foram alimentadas com folíolos dos cinco genótipos até o final da fase larval. No teste de tolerância, os genótipos foram submetidos a desfolha simulada, ou seja, 0%, 25%, 50%, 75% e 100%. Avaliando a produção por 14 meses após a desfolha. O ciclo de vida desde o ovo até a emergência do adulto de O. invirae se completou em 64,59 dias. No teste com chance de escolha, os genótipos mais atrativos foram Compacta x Ekona e Compacta x Ghana, enquanto que o Compacta x Nigéria foi o menos atrativo e menos consumido nos dois testes com lagartas recém-eclodidas. No teste sem chance de escolha com lagartas de 12 dias de idade o tratamento Deli x LaMe foi o menos consumido, o Compacta x Ghana, foi o mais consumido em teste com e sem chance de escolha. No entanto no teste de antibiose foram verificados maiores efeitos dos genótipos estudados nas viabilidades do quinto ínstar larval, no período total da fase larval e fase pupal. No teste de tolerância, os genótipos Deli x LaMe e Compacta x Ekona apresentaram os melhores resultados de produtividade. O genótipo Compacta x Nigéria apresenta resistência do tipo não preferência para alimentação a lagartas recém-eclodidas de O. invirae; o genótipo Deli x LaMe apresenta resistência na categoria antibiose e os genótipos mais tolerantes a desfolha simulada são Deli x Lame, Compacta x Ekona e Compacta x Nigéria.
This research aimed to establish a methodology for creating O. invirae and identify genotypes palm oil presenting this insect resistance sources in the categories by not feeding preference, antibiosis and tolerance, the latter being based on productivity simulation after defoliation in plants. The experiments were conducted in the laboratory, but the tolerance test, which was under field conditions. For the creation of methodology, the caterpillars were reared individually in Petri dishes until the fourth instar and then transferred to larger containers where they remained until the emergence of adults. 5 oil palm genotypes were used for the test no preference for food, antibiosis and tolerance, which are: Deli x Lame control treatment, Compact x Ekona; Deli x Ekona; Compact x Nigeria and Compact x Ghana. The tests with and without choice, were carried out with crawler O. invirae newly hatched and 12 days old. They were evaluated consumption and attractiveness to 1, 3, 5, 10, 15 and 30 minutes and 1, 2, 6, 12, 24, 48 and 72 hours after the release of the insects. In antibiosis test, Crawler O. invirae were fed leaflets of the five genotypes by the end of the larval stage. In the tolerance test, the genotypes were simulated peeling, is, 0%, 25%, 50%, 75% and 100%. Evaluating production for 14 months after defoliation. The life cycle from egg to the emergence of O. invirae adult was completed in 64.59 days. In the test free choice, the most attractive genotypes were Compacta x Ekona and Compact x Ghana, while the Compact x Nigeria was the least attractive and least consumed in both tests with newly hatched caterpillars. In the test no choice with caterpillars 12 days old the Deli x Lame treatment was the least consumed, Compact x Ghana, was the most consumed in test and no choice. However the antibiosis test were observed greater effects of the genotypes studied the viability of the fifth instar larvae, the total period of the larval and pupal stage. In the tolerance test, the Deli x Lame and Compact x Ekona genotypes showed the best productivity results. The Compact x Nigeria genotype is resistant type no preference for feeding the newly hatched larvae of O. invirae; the Deli x Lame genotype presents resistance in antibiose category and the most tolerant genotypes simulated defoliation are Delhi x Lame, Compact x Ekona and Compact x Nigeria.

The African palm or oil palm (Elaeis guineensis Jacq.) is a plant of African origin and considered the major industrialized activity in humid areas, similar in Amazon area. The expansion of oil palm, especially in northern region of Brazil, has presented more phytosanitary problems, including the caterpillars defoliating Brassolis sophorae L. Opsiphanes invirae Hübner (Lepidoptera: Nymphalidae) and borers-of-strain Eupalamides cyparissias cyparissias (Fabricius) (Lepidoptera: Castniidae), weeds and more frequent in the State of Pará. This study aimed to evaluate the potential Trichospilus diatraeae Cherian & Margabandhu (Hymenoptera: Eulophidae) in pupae of O. invirae, B. sophorae and E. cyparissias cyparissias under laboratory conditions. This research was conducted in the laboratory of Plant Complex Agropalma in Thailand city, southeast of Pará State in a room temperature of 25 ± 2 ºC, relative humidity of 70 ± 10% and photophase of 12 hours. The potential of parasitism and progeny production of T. diatraeae in pupae of three species of lepidopteran pests on the cultivation of oil palm, showed that this parasitoid was parasite and progeny produced in pupae of defoliating B. sophorae and O. invirae. The second study was evaluated the reproductive features of T. diatraeae in defoliating species of oil palm (B. sophorae and O. invirae). Results showing that the rate of parasitism and progeny emergence of T. diatraeae pupae was similar in both species. The life cycle of T. diatraeae was lower in pupae of O. invirae (21.50 ± 0.42 days) than in B. sophorae (27.60 ± 1.80 days), but the amount of progeny (669.00 ± 89.62) and dead immature (217.13 ± 58.18) were higher in B. sophorae than in O. invirae (447.83 ± 51.52 and 13.50 ± 5.23), respectively. The sex ratio, longevity of females and males of T. diatraeae were similar in both species were tested. In the third study, the influence of T. diatraeae female age with 12-24, 24- 48, 48-72 and 72 to 96 hours of life was assessed in the reproductive performance of parasitoids in pupae of B. sophorae. Female ages did not affect on parasitism rate of T. diatraeae in B. sophorae pupae, but the emergence of progeny was higher in pupae parasitized by females with 48 to 72 and 72 to 96 hours (70 and 60%) than those parasitized by females between 12 and 24 and 24 to 48 hours old with 20 and 20 %, respectively. The age of T. diatraeae affected on fecundity, the number of dead immature and sex ratio of offspring in pupae of B. sophorae. However, the age of females did not affect on the life cycle of the progeny of T. diatraeae with range from 20.0 ± 1.0 days and 23.0 ± 0.0 days, respectively. Different densities did not affect on parasitism of female T. diatraeae, but the rate of emergence and progeny were higher at 30:1 and 20:1 female/host immature parasitoid and the numbers of deaths were lower in density (1:1, 10:1, 20:1 and 30:1 females/host). The period from egg to adult offspring of T. diatraeae was similar at the different densities of females of this parasitoid. The sex ratio of offspring emerged was the lower density with 10:1 female/host. Females and males of T. diatraeae emerged from the pupae parasitized of B. sophorae were larger (body length) at densities of 20:1 and 30:1 and the head capsules of females were higher at 30:1, 20:1 and 40:1 female/host, with similar values in males. Trichospilus diatraeae was parasite and produced progeny in pupae of B. sophorae and O. invirae, but pupae of B. sophorae were more suitable for producing larger number of offspring of this parasitoid. The best period of reproductive females of T. diatraeae parasitoid in pupae of B. sophorae was between 48 to 96 hours of life at a density of 20 or 30 females/host that provides the highest rates of parasitism, emergence and larger individuals of this parasitoid. The parasitoid T. diatraeae has been good potential to control lepidopteran defoliator pests of oil palm.
O dendezeiro ou palma africana (Elaeis guineensis, Jacq.) é uma planta de origem africana e considerada a principal atividade agroindustrial em regiões tropicais úmidas, semelhantes às da Amazônia. A expansão da dendeicultura, em especial na região Norte do Brasil, tem apresentado mais problemas fitossanitários, incluindo as lagartas desfolhadoras Brassolis sophorae L., Opsiphanes invirae Hübner (Lepidoptera: Nymphalidae) e a broqueadora-da-estirpe Eupalamides cyparissias cyparissias (Fabricius) (Lepidoptera: Castniidae), mais daninhas e freqüentes no Estado do Pará. Esse estudo teve por objetivo avaliar o potencial de Trichospilus diatraeae Cherian & Margabandhu (Hymenoptera: Eulophidae) em pupas de O. invirae, B. sophorae e E. cyparissias cyparissias em laboratório. Esta pesquisa foi realizada no laboratório de Fitossanidade do Complexo Agropalma no município de Tailândia, sudeste do Estado do Pará em sala climatizada à temperatura de 25 ± 2 ºC, umidade relativa de 70 ± 10 % e fotofase de 12 horas. O potencial de parasitismo e produção de descendentes de T. diatraeae em pupas de três espécies de lepidópteros daninhos ao cultivo do dendezeiro, mostrou que esse parasitóide parasita e produz progênie, em pupas das desfolhadoras B. sophorae e O. invirae. O segundo estudo avaliou os aspectos reprodutivos de T. diatraeae nas espécies desfolhadoras do dendê (B. sophorae e O. invirae) mostrando que a taxa de parasitismo e emergência da progênie de T. diatraeae foi semelhante em pupas de ambas as espécies. O ciclo de vida de T. diatraeae foi menor em pupas de O. invirae (21,50 ± 0,42 dias) que nas de B. sophorae (27,60 ± 1,80 dias), mas a quantidade de progênie (669,00 ± 89,62) e imaturos mortos 217,13 ± 58,18 foi maior em B. sophorae que em O. invirae (447,83 ± 51,52 e 13,50 ± 5,23), respectivamente. A razão sexual, longevidade de fêmeas e machos de T. diatraeae emergidos foram semelhantes em ambas as espécies dos lepidópteros-praga. No terceiro estudo, a influência da idade de fêmeas de T. diatraeae com 12 a 24, 24 a 48, 48 a 72 e 72 a 96 horas de vida foi avaliada, no desempenho reprodutivo desse parasitóide em pupas de B. sophorae. A idade de fêmeas não afetou a taxa de parasitismo de T. diatraeae em pupas de B. sophorae, porém a emergência da progênie foi maior em pupas parasitadas por fêmeas com 48 a 72 e 72 a 96 horas (70 e 60%) em relação aquelas parasitadas por fêmeas com 12 a 24 e 24 a 48 horas de idade (20 e 20%), respectivamente. A idade de T. diatraeae afetou, também, a fecundidade, o número de imaturos mortos e a razão sexual da progênie em pupas de B. sophorae. No entanto, a idade de fêmeas não afetou o ciclo de vida da progênie de T. diatraeae que variou de 20,0 ± 1,0 dias a 23,0 ± 0,0 dias, respectivamente. As diferentes densidades não afetaram o parasitismo de fêmeas de T. diatraeae, mas a taxa de emergência e a progênie foram maiores nas densidades de 30:1 e 20:1 fêmeas/hospedeiro e a quantidade de imaturos mortos foram menores nas densidades (1:1, 10:1, 20:1 e 30:1 fêmeas/hospedeiro). O período de ovo a adulto da progênie de T. diatraeae foi semelhante nas diferentes densidades de fêmeas desse parasitóide. A razão sexual da progênie emergida foi menor na densidade de 10:1 fêmeas/hospedeiro. Fêmeas e machos de T. diatraeae, emergidos de pupas de B. sophorae parasitadas foram maiores (comprimento do corpo) nas densidades de 20:1 e 30:1 e as cápsulas cefálicas de fêmeas foram maiores nas densidades de 30:1, 20:1 e 40:1 fêmeas/hospedeiro, com valores semelhantes em machos. Portanto, Trichospilus diatraeae parasita e produz progênie em pupas de B. sophorae e O. invirae, mas aquelas pupas de B. sophorae são mais adequadas por produzir maior número de descendentes desse parasitóide. O melhor período reprodutivo de fêmeas de T. diatraeae parasitando pupas de B. sophorae foi entre 48 a 96 horas de vida na com densidade de 20 ou 30 fêmeas/hospedeiro que proporciona maiores taxas de parasitismo, emergência e maior tamanho de indivíduos desse parasitóide. O parasitóide T. diatraeae apresenta potencial para controlar lepidópteros desfolhadores do dendê.

Abstract:
Biomass is an important new energy source because it is indigenous to every part of the world, inexpensive and renewable. Malaysia's ability to produce and consistently export a large quantity of high quality palm oil has made it one of the major vegetable oil exporters in the world. By-products and waste from the palm oil mills are generated in significant amounts and mainly consist of empty fruit bunches, oil palm stone, oil palm shell, palm kernel cake and palm oil mill effluent. Some of this waste is currently used as fuel for boilers with low energy efficiency, as a soil conditioner, or in furniture making. There is a significant interest in recovering energy from oil palm shells and extensive research has been carried out in this area in other studies. However, research on energy production from oil palm stone (OPS) and palm kernel cake (PKC) is very limited. Waste from the oil palm industry, especially OPS and PKC, is abundant and could help to meet the energy demand if properly managed. The main objective of this PhD study was to investigate the main characteristics of the thermo-chemical conversion of OPS and PKC. A series of combustion and pyrolysis tests were carried out using OPS and PKC as the raw materials in fixed bed and pilot-scale fluidised bed reactors. In addition, the FLIC modelling code was used to predict key parameters including theoretical solid temperature and gas composition, and to validate the experimental results from fixed bed combustion tests. Pelletisation was also carried out on PKC due to the loose nature and small size of the particles. In the series of pyrolysis tests using OPS and PKC carried out in a fixed bed reactor, the effects of heating rate at the temperature of 700°C on the yields and properties of the pyrolysis products were investigated. The calorific values of the chars obtained from the OPS and PKC were approximately 28 MJ/kg. The properties of the chars produced were similar to bituminous coal in terms of their calorific value and carbon content. The pyrolysis liquids obtained from the OPS and PKC had calorific values of 21-38 MJ/kg. The pyrolysis liquids obtained from OPS were in the form of a homogeneous liquid, whilst that derived from PKC contained more than half as an aqueous fraction. The results from the fixed bed combustion tests showed that the burning rates increased with an increase in the air flow rate. In addition, results from the FLIC code used to simulate the fixed bed combustion of the oil palm stone showed good agreement with the experimental data in terms of predicting the dynamic temperature profiles along the bed height and the flue gas composition. The effect of primary air flowrate and initial bed temperature were the main parameters investigated in the pilot-scale fluidised bed combustion tests. Both the internal temperature and the surface temperature were found to decrease as the primary air flowrate increased. In all tests CO emissions were less than 0.2%. The emissions of SO2 and HCl ranged from 0.02 ppm to 0.05 ppm, significantly below the levels set by legislation. Stable combustion was observed at a bed temperature of 950°C. The most abundant elements found in the ash were Al, Ca, Fe, K, Mg, Mn, P, S and Si. The variables explored in the pelletisation of PKC were pressure, temperature, fuel moisture content and the effect of binders, which all had significant effects on density and tensile strength. The most favourable conditions for pellet production were found to be a pressure of 9338 psi/64.38 MPa, a temperature of 80-100°C and a fuel moisture content of 7.9%. These pellets had densities of 1184-1226 kg/m3 and tensile strengths of 930-1007 kPa. Adding small amounts of caustic soda (1.5-2.0wt %) to the PKC under these conditions increased the tensile strength to 3055 kPa, whereas starch additives were not found to be effective binders.

Abstract:
With a rapidly growing world population, the demand for palm oil is increasing. In 2010, palm oil accounted for 36.5% of the world's vegetable oil production and it is projected to be the leading vegetable oil in the world by 2016. The Malaysian palm oil industry is committed to delivering sustainable palm oil products to its customers. This is being achieved through the establishment of a roadmap identifying strategies and action plans that are priorities for 2009 to 2020. These include the implementation of IS014001 (Environment Management Systems), since 2004, and IS014040 (Life Cycle Assessment), since 2006. The implementation of carbon footprint labelling is currently being carried out as part of continuous improvements for the delivery of sustainable palm oil. The aim of this research was to investigate tools and methods that might be used in the delivery of sustainable Malaysian palm oil. Interviews based on a semi- structured questionnaire were used to identify current practices in the Malaysian palm oil industry. Results from the interviews highlighted the importance of IS014001 and IS014040 implementations in the delivery of sustainable palm oil. Case studies related to IS014001 and IS014040 were used to derive stakeholder needs for sustainable palm oil. These informed the creation of a supply network map that was used to visualisethe Malaysian palm oil industry and the extent of current IS014001 and IS014040 implementations. It was found that neither IS014001 nor ISO 14040 were implemented across the whole supply network. The supply network map was used to frame simulations of parts of the Malaysian palm oil industry system, namely, the plantation, mill and mill-refinery. Early results indicated that computer simulations could be a valuable tool that would complement existing methods such as Environmental Management Systems and Life Cycle Assessment. Simulation models could be populated with real-world data and used to inform policies for Malaysian palm oil production. For better traceability of decision making, considerations would need to be given to the identification of system boundaries, simulation parameters related to stakeholder needs, the capture of operating environments, and risks and uncertainties in the validation of models.

Abstract:
Oil palm (Elaeis guineensis) is of strategic importance to the Ghanaian economy. It is the second most important industrial crop after cocoa and is used widely in local food preparation as well as in industrial processing. In spite of its importance, however, oil palm has consistently underperformed since the early twentieth century. This paper conducts a value chain analysis of the crop, foregrounding the political economy factors that shape the performance of the sector. It draws on a combination of in-depth interviews conducted in March 2020 with a variety of value chain actors and a review of the secondary literature. Additionally, between late May and early June 2020, twelve further interviews were conducted as part of a rapid market survey to assess the impact of the COVID-19 pandemic on the value chain.
