impacts the morphology, physiology, reproduction, and lifespan of the insectTrypanosomatids are protozoan parasites that infect thousands of globally dispersed hosts, potentially affecting their physiology. Several species of trypanosomatids are commonly found in phytophagous insects.is a gut-restricted ...

Abstract Most theoretical models of the evolution of life histories have incorporated the fundamental assumption that costly activities such as growth, repair and reproduction are to some extent mutually exclusive (e.g., Williams 1966, Gadgil and Bossert 1970, Schaeffer 1974, Charlesworth 1980). This...
Ours is the first reported evidence of a lifespan/diet breadth trade-off at the interspecific level among insects, and it confirms the findings of a previous study in which the degree of habitat specialisation among arthropods was inversely related to proxy measures of the degree of search time...
Lifespan is often linked to an organism’s reproductive strategy. R-selected species (like insects) reproduce quickly and in large numbers, prioritizing rapid growth and reproduction over longevity. In contrast, K-selected species (like whales) invest more in fewer offspring, ensuring their survival...

Males and females have different routes to successful reproduction, resulting in sex differences in lifespan and age-specific allocation of reproductive effort. The trade-off between current and future reproduction is often resolved differently by males and females, and both sexes can be constrained in...
At least eight genetic forms of thely- tokous parthenogenesis have been described, haplodiploidy is dominant in solitary and social Hymenoptera, hermaphroditism in scale insects, androgenesis is widespread in stick insects, and no less than four variations of hybridogenesis have been reported in ...
