Can Preference for Oviposition Sites Initiate Reproductive Isolation in Callosobruchus maculatus?
Theory has identified a variety of evolutionary processes that may lead to speciation. Our study includes selection experiments using different host plants and test key predictions concerning models of speciation based on host plant choice, such as the evolution of host use (preference and performance) and assortative mating. This study shows that after only ten generations of selection on diff...
متن کاملGenetic architecture of population differences in oviposition behaviour of the seed beetle Callosobruchus maculatus.
Few studies have examined the genetic architecture of population differences in behaviour and its implications for population differentiation and adaptation. Even fewer have examined whether differences in genetic architecture depend on the environment in which organisms are reared or tested. We examined the genetic basis of differences in oviposition preference and egg dispersion between Asian...
متن کاملOviposition decisions in the seed beetle, Callosobruchus maculatus (Coleoptera: Bruchidae): effects of seed size on superparasitism
The seed parasite Callosobruchus maculatus generally disperses eggs uniformly among seeds. We used cowpeas (Vigna unguiculata) of two class sizes (large and small) to test predictions based on a simple resource threshold model that females will distribute eggs among seeds in a manner that maximizes the amount of resources allocated to each offspring. When females were presented with multiple se...
متن کاملDeterrent activity of plant lectins on cowpea weevil Callosobruchus maculatus (F.) oviposition.
A set of 14 plant lectins was screened in a binary choice bioassay for inhibitory activity on cowpea weevil Callosobruchus maculatus (F.) oviposition. Coating of chickpea seeds (Cicer arietinum L.) with a 0.05% (w/v) solution of plant lectins caused a significant reduction in egg laying. Control experiments with heat inactivated lectin and BSA indicated that the observed deterrent effects are s...
متن کاملEvaluation of some plant products for their oviposition deterrent properties against the Callosobruchus maculatus (F.) on Chik pea seeds
Investigated six plant extracts viz.,, kaner leaf extract (Nerium indicum), khejri leaf extract (Prosopis cineraria), neem leaf extract (Azadirachta indica), safeda leaf extract (Eucalyptus globulus), tomato leaf extract (Lycopersicum esculentum) and mustard seed extract (Brassica compestris) and four plant powders viz.,, black pepper powder (Piper nigrum), garlic clove powder (Allium sativum),...
