Storage at low temperature is a valuable method for increasing the shelf-life of natural
enemies such as insect parasitoids. Cold storage is usually performed under sub-optimal …

The diverse ecology of parasitoids is shaped by extrinsic competition, ie, exploitative or
interference competition among adult females and males for hosts and mates. Adult females …

The trade-off between the need to obtain new knowledge and the need to use that
knowledge to improve performance is one of the most basic trade-offs in nature, and optimal …

Abstract The neuromodulator serotonin (5-HT) has been implicated in a variety of functions
that involve patience or impulse control. Many of these effects are consistent with a long …

Studies of the fitness consequences of behavioral types often focus on isolated behaviors
and ignore potential across-context correlations that may affect fitness. This approach leads …

As most parasitoids are time limited, they usually die before they have laid all their eggs. In
such cases, optimal foraging theory predicts that female parasitoids will adopt behavioral …

We used a computer game to examine three aspects of patch-leaving decisions in humans:
how well do humans perform compared to the optimal policy, can they adjust their behaviour …

Ectotherm organisms are known to be plastic in their responses to temperature. Individuals
developing at low temperatures usually achieve a larger body size through a lower growth …

Foraging for food is an integral part of animal survival. In small insects and invertebrates,
multisensory information and optimized locomotion strategies are used to effectively forage …

In this chapter, we consider practical aspects of the foraging behaviour of insect natural
enemies in its widest sense (so wide that we even include a few examples concerning non …
