Effects of Abiotic Factors on HIPV‐Mediated Interactions between Plants and Parasitoids

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
In contrast to constitutively emitted plant volatiles (PV), herbivore‐induced plant volatiles (HIPV) are specifically emitted by plants when afflicted with herbivores. HIPV can be perceived by parasitoids and predators which parasitize or prey on the respective herbivores, including parasitic hymenoptera.

Chemical Ecology of Egg Parasitoids Associated with True Bugs

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Parasitoids representing some 15 families of Hymenoptera develop in insect eggs; three of these families, Platygastridae (= Scelionidae), Mymaridae, and Encyrtidae, are associated with Heteroptera. Several species of heteropteran egg parasitoids are or may be important for biological pest control.
