Efficacy of dodder vine extract as seed protectant against pulse beetle, Callosobruchus chinensis (Coleoptera: Bruchidae)
The experiment was conducted to find out the efficacy of dodder vine extract as seed protectant against pulse beetle, Callosobruchus chinensis on gram seed in the laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during the period of February to May, 2009. The concentrations of dodder vine extract were 5, 2 and 1% respectively. Efficacies of these treatm...
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 کاملEfficacy of Cinnamon and Citronella Oil Vapours in the Control of Callosobruchus chinensis L. in Bulk Stored Green Gram
Efficacy of Cinnamon bark oil vapour (Cinnamomam verum Presl.) and Citronella oil vapour (Cymbopogon nardus L.) were evaluated for the control of infestations of Callosobruchus chinensis L in bulk stored green gram. Both oils were used at 5ml and 10ml/5kg of seeds in 3L plastic baskets. Oviposition and damaged seeds were detected for up to two months of period. At the end of the storage period,...
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 کاملSex-specific genetic variances in life-history and morphological traits of the seed beetle Callosobruchus maculatus
Knowledge of heritability and genetic correlations are of central importance in the study of adaptive trait evolution and genetic constraints. We use a paternal half-sib-full-sib breeding design to investigate the genetic architecture of three life-history and morphological traits in the seed beetle, Callosobruchus maculatus. Heritability was significant for all traits under observation and gen...
