An exotic parasitoid provides an invasional lifeline for native parasitoids
The results of experiments examining the interspecific interactions between a native European egg parasitoid, Trissolcus cultratus, and an Asian parasitoid, Trissolcus japonicus (a candidate for the biological control of Halyomorpha halys), showed that the native species can act as facultative hyperparasitoid of the exotic one.

Prospects of herbivore egg‐killing plant defenses for sustainable crop protection
Exploiting egg‐killing defense traits should be promising to reduce crop losses in future. However, little is known on the mechanisms and on the genetic basis of egg‐killing traits. In our review article, we address three main topics: (1) the phylogeny and ubiquity of plants expressing insect egg‐killing defenses, (2) mechanisms underlying and to be ...

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

Testing the habituation assumption underlying models of parasitoid foraging behavior [PDF]
Background Habituation, a form of non-associative learning, has several well-defined characteristics that apply to a wide range of physiological and behavioral responses in many organisms.

Chemical Ecology of Egg Parasitoids Associated with True Bugs
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.

Parasitoid's performance is subject to parasitism decisions influenced by host quality and parasitoid's age. We evaluated parasitism, emergence, and the progeny sex ratio proportions of Telenomus podisi (Ashmead), Trissolcus urichi (Crawford), and Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae) females of different age attacking Piezodorus

Floral nectar is a sugar‐rich resource which is essential for covering the energetic and nutritional requirements of adult parasitoids. Recent research has shown that floral nectar is ubiquitously colonized by microbes, however how nectar‐inhabiting microbes affect parasitoid performance is poorly investigated.

The scutellerid shield bug, Deroplax silphoides (Thun.) (Hemiptera: Scutelleridae), is a new recorded insect species (in Egypt) attacking the ornamental plant, Dodonaea viscosa (L.). The bug feeds by sucking sap from flowers and green seeds of this plant

Insect–microbe interactions and their influence on organisms and ecosystems
Insect‐symbiont interactions can have a variety of impacts on organisms and the ecosystem. These multitrophic interactions can result in differential attraction of beneficial insects or natural enemies. Additinoally, these interactions can influence plant and/or soil health as well as microbiome composition.

Oviposition fluids from adult wasps mediate interspecific competition between parasitoid larvae
Interspecific competition between parasitoid larvae sharing a host is often thought to be resolved by physical combat. We show that injected oviposition fluids also mediate interspecific larval competition. We demonstrate that venom and calyx fluid from a solitary parasitoid can inhibit the development of a gregarious competitor, even in the absence of
