Four types of laboratory populations of the bean weevil (Acanthoscelides obtectus) have been developed to study the effects of density-dependent and age-specific selection. These populations have been selected at high (K) and low larval densities (r) as well as for reproduction early (Y) and late (O) in life. The results presented here suggest that the r-(More)
Relationship of superoxide dismutase and catalase activities and aging were tested using bean weevil lines selected for postponed senescence. The beetles of different age (young and old) and mating status (virgin and mated) from the extended longevity lines were compared with their counterparts derived from the short-lived lines for activities of SOD and(More)
We investigated the additive, dominance and epistatic genetic effects underlying differentiation in oviposition preference between two populations of the seed beetle Acanthoscelides obtectus evolved in the laboratory for 102 generations on bean and chickpea seeds. We reared and tested females on each of two host legumes. The populations differed in mean(More)
In this study we examined the direct and correlated responses for fast and slow preadult development time in three laboratory populations of the bean weevil (Acanthoscelides obtectus). The first population ("base," B) has experienced laboratory conditions for more than 10 years; the second ("young," Y) and the third ("old," O) populations were selected for(More)
