Identification of biologically relevant compounds in aboveground and belowground induced volatile blends [PDF]

, 2010
Plants under attack by aboveground herbivores emit complex blends of volatile organic compounds (VOCs). Specific compounds in these blends are used by parasitic wasps to find their hosts.

Mechanical interaction of the egg parasitoid Anastatus bifasciatus (Hymenoptera: Eupelmidae) with artificial substrates and its host egg [PDF]

, 2022
Egg parasitoids play an important role in biological control of pest species attacking and killing their hosts at an early stage of their development. During the antagonistic coevolution with their hosts, egg parasitoids have developed a great ability to

Host Sex Discrimination by an Egg Parasitoid on Brassica Leaves

Journal of Chemical Ecology, 2011
Egg parasitoids are able to find their hosts by exploiting their chemical footprints as host location cues. In nature, the apolar epicuticular wax layer of plants that consists of several classes of hydrocarbons serves as the substrate that retains these contact kairomones. However, experiments on chemical footprints generally have used filter paper as

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

Pest Management Science, EarlyView.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, EarlyView.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Encapsulation and Self-Superparasitism of Pseudapanteles dignus (Muesebeck) (Hymenoptera: Braconidae), a Parasitoid of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). [PDF]

PLoS ONE, 2016
Endoparasitoids can be killed by host encapsulation, a cellular-mediated host immunological response against parasitism that involves hemocytes aggregation.
