Drought and root herbivory interact to alter the response of above-ground parasitoids to aphid infested plants and associated plant volatile signals. [PDF]

open access: yesPLoS ONE, 2013
Multitrophic interactions are likely to be altered by climate change but there is little empirical evidence relating the responses of herbivores and parasitoids to abiotic factors.

Microgastrinae (Hymenoptera: Braconidae) parasitizing Epirrita autumnata (Lepidoptera: Geometridae) larvae in Fennoscandia with description of Cotesia autumnatae Shaw, sp. n. [PDF]

open access: yes, 2013
The microgastrine subset of hymenopteran parasitoids of the geometrid Epirrita autumnata is investigated in Fennoscandia. Ecology, including population dynamics, of the moth has been intensively studied in northern and mountainous Finland, Norway and ...

Infochemical use and dietary specialization in parasitoids: a meta‐analysis

open access: yesEcology and Evolution, 2017
Many parasitoid species use olfactory cues to locate their hosts. In tritrophic systems, parasitoids of herbivores can exploit the chemical blends emitted by plants in reaction to herbivore‐induced damage, known as herbivore‐induced plant volatiles ...

Attack and Success of Native and Exotic Parasitoids on Eggs of Halyomorpha halys in Three Maryland Habitats

open access: yesPLoS ONE, 2016
Egg parasitoids of the exotic invasive brown marmorated stink bug, Halyomorpha halys (Stål), were investigated using lab-reared fresh (live) and frozen (killed) lab-reared sentinel egg masses deployed for 72h on foliage in three habitats—woods, orchard ...

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

“Tremble, pests”: Insect natural enemy‐induced changes in pests before attack and their implications for biological control

open access: yesNew Plant Protection, EarlyView.
Abstract Insect natural enemies, encompassing predators and parasitoids, serve as vital regulators of pest populations and architects of ecosystem balance. Most studies on natural enemies have focused on understanding the mechanisms by which these insects eliminate pests after an attack.

Regulatory mechanisms of reproduction in locusts and grasshoppers

open access: yesNew Plant Protection, EarlyView.
Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.
