Although reproductive strategies can be influenced by a variety of intrinsic and extrinsic
factors, life history theory provides a rigorous framework for explaining variation in …

Environmental stress in newly-emerged adult insects can have dramatic consequences on
their life traits (eg, dispersion, survival and reproduction) as adults. For instance, insects …

Glucocorticoids circulating in breeding birds during egg production accumulate within eggs,
and may provide a potent form of maternal effect on offspring phenotype. However, whether …

The terminal investment hypothesis proposes that decreased expectation of future
reproduction (eg, arising from a threat to survival) should precipitate increased investment in …

Infections with potentially lethal pathogens may negatively affect an individual's lifespan and
decrease its reproductive value. The terminal investment hypothesis predicts that individuals …

The dynamic terminal investment threshold model posits that the propensity of an individual
to terminally invest in response to an immediate survival threat, such as an infection …

Chlorantraniliprole is a diamide insecticide that has been widely used against lepidopteran
pests. However, the actions of this compound on non-targeted insect pests such as the …

Variable spring temperatures may expose developing insects to sublethal conditions,

Nutritional geometry has advanced our understanding of how macronutrients (eg, proteins
and carbohydrates) influence the expression of life history traits and their corresponding …

Nuptial food gifts are an integral feature of the mating systems of a wide variety of insects. A
pervasive feature of the majority of these gifts is that they afford the male direct access to the …
