Resource quality affects restlessness in the parasitoid wasp Nasonia vitripennis
Optimal foraging theory, specifically the marginal value theorem, predicts quicker leaving (shorter residence time) from poorer patches. One proximal mechanism for achieving the leaving is that exposure to lower-quality resources may trigger increased restlessness (proportion of time in locomotion). Which aspects of host quality, if any, affect restlessness was examined in females of the parasi...
متن کاملSib-mating does not lead to facultative sex ratio adjustment in the parasitoid wasp, Nasonia vitripennis
Sex ratio theory predicts that in haplodiploid species, females should lay a relatively more female-biased offspring sex ratio when they mate with a sibling compared with when they mate with a non-relative. This is because in haplodiploids, inbreeding leads to females having greater relatedness to daughters relative to sons. This prediction has only been tested in the parasitoid wasp Nasonia vi...
متن کاملSex ratios under asymmetrical local mate competition in the parasitoid wasp Nasonia vitripennis
Sex ratio theory has proved remarkably useful in testing the adaptive nature of animal behavior. A particularly productive area in this respect is Hamilton’s theory of local mate competition (LMC), which has been extended in numerous directions to include greater biological realism, allowing more detailed tests in specific organisms. We have presented one such extension, termed asymmetrical LMC...
متن کاملInformation use in space and time: sex allocation behaviour in the parasitoid wasp Nasonia vitripennis.
Behavioural decisions require the appropriate use of relevant information about the environment. However, individuals may have imperfect information, imposing a constraint on adaptive behaviour. We explored how information use influences the sex allocation behaviour of the parasitoid wasp Nasonia vitripennis in response to local mate competition. Optimal sex ratios under local mate competition ...
متن کاملReproductive strategies under multiparasitism in natural populations of the parasitoid wasp Nasonia (Hymenoptera).
Parasitoid Nasonia wasps adjust their progeny sex ratio to the presence of conspecifics to optimize their fitness. Another trait under female control is the induction of offspring diapause. We analysed progeny sex ratios and the proportion of diapausing offspring of individual Nasonia females in host patches parasitized by two species, Nasonia vitripennis and Nasonia giraulti, in North American...
