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:
Bruchid pests are of considerable economic importance, infesting legume seeds and pods in fields and stores, predominately in the semi-arid tropics. One of the foremost bruchid pests"Callosobruchus maculatus is a niche generalist in that it can infest seeds whilst within pods or when loose. It exhibits a much greater degree of polyphagy than its wild relatives, perhaps partly due to behavioural plasticity. As their larvae are restricted to a single seed, resources available for growth are directly related to egg distribution by the ovipositing female. Host selection is a complex process and involves host finding, recognition (which may occur before or after contact with the plant), and host acceptance which is manifested as contact inspection behaviour and culminates in oviposition. Numerous factors influence these processes including the nature of host chemistry and the presence of conspecific epideictic pheromones. The purpose of this study was to investigate the factors which modulate the tendency to oviposit and oviposition behaviour itself. 2 The oviposition behaviour of newly emerged beetles was recorded on several seeds that vary in their attractiveness as hosts. The behavioural repertoire and the stereotypical sequences that characterise the acceptance or rejection of a host were recorded on pristine and egg laden seeds. These sequences were used to construct flow charts of transitions between the most common behaviours. Several indicators of a host's acceptahility were identified and quantified, including the duration of selected key behaviours. The combination of behaviours exhibited, their position in the transitional matrix and their respective durations, indicated the relative acceptability of the host seeds studied, and provided information on how the different sense organs have complementary roles in the process of host acceptance. This demonstrated that the perception of primary host and conspecific stimuli which influence host acceptance is undertaken by the palps and., to a lesser extent, by the antennae. The study of oviposition behaviour in conjunction with studies on the course of oviposition over extended periods on real and artificial hosts provided the tools by which the chemical bases of host acceptance could be investigated. Host seed extracts were screened for their ability to influence behaviour, and some of the active components were identified as a number of commonly occurring fatty acids. These same fatty acids have been shown to stimulate egg laying, and in different proportions and concentrations, to deter oviposition both as components of a conspecific oviposition deterrent pheromone, and as components of vegetable oils added to stored seeds as a protectant

Abstract:
In common bean (Phaseolus vulgaris), the main seed storage pests are the bruchid beetles. Damage done to the seed by the larvae has a large impact on seed quality and yield. Arcelin (ARC), phytohaemagglutinin (PHA), and α-amylase inhibitor (α-AI) are linked seed storage proteins that form the APA locus on chromosome Pv04 and are associated with resistance. A major breeding objective is to introduce bruchid resistance into common bean from a resistant tepary genotype, G40199, by introgressing the resistant APA locus into susceptible common bean backgrounds. Here we developed a molecular marker that tracks the introgression. A set of PCR primers to the α-amylase inhibitor locus amplified a DNA fragment that showed a 45 base pair insertion in the middle of a lectin Leg_b domain. This enhanced locus characterization and insertion/deletion marker may preclude the need for bruchid resistance screening early in the breeding.

Abstract:
Phaseolus vulgaris (common bean) is an important source of protein for human and animal consumption. Economic losses post-harvest in storage are primarily due to the bruchid beetles Acanthoscelides obtectus (Bean Weevil) and Zabrotes subfasciatus (Mexican Bean Weevil). Wild-lines exhibiting resistance to these two species have been found and the mechanisms of resistance to each species are investigated. The mechanisms of resistance to the two species are found to be multiple, and different for each species. In the case of Z. subfasciatus, the presence of a novel storage protein and absence of the conventional storage protein constitutes the primary mechanism. The novel protein ("arcelin") is antimetabolic when included in artificial diets. In vitro digestibility studies indicate that it is indigestible to Z. subfasciatus larval gut proteases, and since arcelin constitutes the major protein of the seed the larvae starve. Arcelin has a similar amino- acid sequence to PHA. Also present is WBAI, a highly specific inhibitor of larval amylase of the two bruchid pests Z. subfasciatus and Callosobruchus maculatus, whilst having virtually no inhibitory activity on the mammalian amylase, nor on other insect, bacterial nor fungal enzymes. WBAI is similar in gross structure to the conventional amylase inhibitor obtainable from RKB (commercial P. vulgaris), and both are also immunologically similar to PHA. Both of these mechanisms are suitable for incorporation into commercial seed, and the former has already been tested, using meal from seeds, in feeding trials using rats, confirming absence of mammalian toxicity. Resistance to A. obtectus damage is accompanied by reduced starch content, and high content of an acidic polysaccharide (whose structure has not been elucidated). No protein cause for resistance was found. Inheritance of resistance to A. obtectus is recessive. Since the factor responsible for resistance is not a primary gene product and is expressed recessively, this factor is unsuitable for incorporation into breeding lines to be used for developing commercial cultivars.
