Assumptions about mating structure have been important in the development of sex ratio theory. Fisher's theory frequency dependent selection for equality, and Charnov's allocation when host quality varies, assume panmixis, whereas Hamilton's local mate competition assumes occurs only at natal patch. An group organisms stimulating theory, its empirical testing, parasitoid Hymenoptera. These exhibit many life history variations possess a mechanism by which females can adaptively control their...
Many animals avoid attack from predators through toxicity or the emission of repellent chemicals. Defensive mimicry has evolved in many species to deceive shared predators, for instance colouration and other morphological adaptations, but hardly ever seems involve multi-trait similarities. Here we report on a wingless parasitoid wasp that exhibits full spectrum traits mimicing ants affording protection against ground-dwelling (wolf spiders). In body size, morphology movement Gelis agilis...
The existence of spiteful behaviors remains controversial. Spiteful are those that harmful to both the actor and recipient, they represent one four fundamental types social behavior (alongside selfishness, altruism, mutual benefit). It has generally been assumed conditions required for spite evolve too restrictive, so is unlikely be important. This idea challenged in recent years, with realization localized competition can relax evolve. Here we develop a theoretical model prime candidate...
Abstract. Atypical of the parasitoid Hymenoptera, female Goniozus nephantidis Muesebeck remain with offspring until they pupate. This behaviour will only have evolved if consequent reduction in fecundity is outweighed by fitness returns. G.nephantidis competes for hosts conspecific and non‐conspecific parasitoids. The effectiveness at deterring superparasitism multiparasitism tested. Brood survivorships were compared when Bracon hebetor Say intrude on mother present absent different...
Host plant identity and host chemistry have often been shown to influence finding acceptance by natural enemies but comparatively less attention has paid the tritrophic effects of on other enemy fitness correlates, such as survivorship, clutch size, body sex ratio. Such studies are central understanding both selective impact plants well potential for reciprocal traits. We examined in a system consisting three apiaceous ( Pastinaca sativa , Heracleum sphondylium H. mantegazzianum ), parsnip...
Abstract Selfish interests usually preclude resource sharing, but under some conditions collective actions enhance per capita gains. Such Allee effects underlay early explanations of social evolution current understanding focusses on kin selection (inclusive fitness). We find an effect that explains unusual quasisociality (cooperative brood care) among parasitoid wasps without invoking or precluding effects. In Sclerodermus harmandi , individual females produce most offspring when exploiting...
Extremely female-biased sex ratios of parasitoid wasps in multiple-foundress groups challenges evolutionary theory which predicts diminishing bias as foundress numbers increase. Recent based on cooperation has achieved qualitative rather than quantitative success explaining among parasitoids the genus Sclerodermus. Here, we develop an explanation, expanding local mate competition, observation that male production seems dominated by some foundresses within groups. Two ratio effects arise from...
The release of biological control agents has been an important means controlling invasive species for over 150 years. While these releases have led to the sustainable 250 pest and weed worldwide, a minority caused environmental harm. A growing recognition risks focus on risk assessment beginning in 1990s along with precipitous decline releases. this new greatly improved safety control, it came at cost lost opportunities solve problems associated species. framework that incorporates benefits...
