Abstract:

Bruchid beetles are economically important pests of grain legumes. Their medium to high level infestation is being controlled with insecticide. This study investigated the effects of environmental factors such as temperature, toxicant concentration, food and bruchid geographical strain on malathion tolerance in Callosobruchus species (c. maculatus, C. chinensis and C. rhodesianus). There were variations in insecticide tolerance among the species and C. maculatus which is the most widely spread and known showed the highest tolerance. Geographical origin had a pronounced impact on the response o

Abstract:

Male-female coevolution is at the heart of biology. It is responsible for much of the diversity we see in behaviour and morphology, and it is thought to be an important engine of speciation. The pattern of intersexual coevolution is well established in many taxa, yet understanding of the processes responsible for male-female coevolution remains incomplete. By studying interspecific variation within a closely related group of species, we can gain important information about how traits and behaviours have evolved. In the work done for this thesis, we studied a group of seed beetle species. Our r

Abstract:

Common bean (Phaseolus vulgaris L.) is world’s most important grain legume for human consumption and the crop is grown annually on more than 14 million hectares. Drought stress limits common bean production worldwide. Understanding drought resistance mechanisms and identifying key plant traits may help to select the superior performers of crop under drought stress. Storage insect attacks on stored beans are also known to be substantial all over the world. Understanding the resistance mechanisms to bruchid weevils and identifying resistant genes can help to develop resistant varieties. Particip

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 in
