Reevaluation of the value of autoparasitoids in biological control. [PDF]
PLoS ONE, 2011 Autoparasitoids with the capacity of consuming primary parasitoids that share the same hosts to produce males are analogous to intraguild predators. The use of autoparasitoids in biological control programs is a controversial matter because there is ...

Primary and secondary sex ratios in a gregarious parasitoid with local mate competition [PDF]
Behavioral Ecology, 2012 Sex allocation is one of the most productive domains of behavioral ecology and has led to a sophisticated understanding of factors influencing an organism’s reproductive decisions. The production of strongly female-biased sex ratios, with low between group variance, is selected for when single mothers produce groups of sibmating progeny.

Differing success of defense strategies in two parasitoid wasps in protecting their pupae against a secondary hyperparasitoid [PDF]
, 2011 During their larval development, endoparasitoids are known to dispose of host resources in several different ways. Some parasitoid wasps consume most or all tissues of the host, whereas others consume a small fraction of host resources and either ensure ...

Intraguild Predation of Hippodamia variegata on Aphid Mummies in Cotton Field
Insects, 2023 Intraguild predation among arthropod predators in agricultural ecosystems may have a negative impact on biological control. At present, there are few direct reports on trophic relationships among participants of predation in field groups.
