Intraguild predation among biological-control agents: theory and evidence
TLDR
The ability to develop successful programs of biological control will be enhanced by field studies that address the complexity of trophic interactions occurring in agroecosystems, and it is hypothesize that IGP by predators is particularly likely to influence the efficacy of Biological control.
Adult feeding and lifetime reproductive success in the parasitoid Aphytis melinus
TLDR
The availability of a sugar‐rich food interacts strongly with host feeding in influencing longevity and fecundity and has a strong direct effect on egg resorption.
Sex Ratios and Multifaceted Parental Investment
TLDR
Simple models are developed that predict that a greater availability of resources used for provisions will lead to an increase in the amount provisioned per offspring and an increased in the numerical or biomass proportion of females produced.
Higher-order predators and the regulation of insect herbivore populations.

TLDR
The hypothesis that higher-order predators may constrain the top-down control of herbivore populations is evaluated and manipulative field experiments will be especially valuable in furthering the understanding of their roles in arthropod communities.
Influence of intraguild predation among generalist insect predators on the suppression of an herbivore population
TLDR
It is concluded that intraguild predation in this system is wide-spread and has potentially important influences on the population dynamics of a key herbivore.
AN EVOLUTIONARY ARGUMENT FOR EGG LIMITATION

TLDR
Simple models are constructed that predict that egg limitation will be a common component of parasitoid life histories, and which question has not been posed, is whether egg limitation is a plausible outcome of the evolutionary process.
Intraguild interactions in aphid parasitoids
TLDR
It is concluded that intraguild interactions have a primary effect in driving fluctuations in aphid parasitoid populations and can substantially alter the effectiveness of aphid Parasitoids as biological‐control agents.
Egg load as a major source of variability in insect foraging and oviposition behavior
TLDR
It is suggested that insects adjust their foraging and oviposition behavior in response to their perceived risk of becoming egg limited, and is therefore particularly amenable to analysis with optimization models.
