Towards a general perspective on life-history evolution and diversification in parasitoid wasps

摘要: In attempting to explain the marked interspecific variation evident in many components of life-history parasitoid wasps, biologists have sought identify general predictors suites ‘important’ traits. Two currently use are: (1) mode larval development relation future host growth and [no further (= idiobiosis) versus continued koinobiosis)]; (2) ovigeny index (the degree which lifetime potential complement eggs is mature at start adult life females). These been postulated share several correlates, an earlier comparative analysis showed be associated. questions are thus posed: variables actually common both idio/koinobiosis index, responsible for link between these two axes diversity? Through analyses a database traits 133 wasp species, four correlates out 11 we investigated shown account association predictors: relative level resource investment per egg (degree yolk richness, lower koinobionts), pre-adult lifespan (longer female (shorter maximum load (larger koinobionts). Our findings pave way full integration dichotomous hypothesis with hypothesis, provide holistic perspective on diversity evolution.
