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.

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 ...

Host Searching by Egg Parasitoids: Exploitation of Host Chemical Cues

open access: yes, 2010
Insect parasitoids are considered “keystone species” in many ecosystems in terms of biodiversity, ecological impact and economic importance (Vinson 1985, LaSalle and Gauld 1993, Hawkins et al. 1999).

Saltbush-associated Asphondylia species (Diptera: Cecidomyiidae) in the Mediterranean Basin and their chalcidoid parasitoids (Hymenoptera: Chalcidoidea) [PDF]

open access: yes, 2014
Numerous species of gall midges (Diptera: Cecidomyiidae) have been recorded from saltbush (Chenopodiaceae: Atriplex) around the world but only 11 of them belong to the large cecidomyiid genus Asphondylia. Of these, two species were de-scribed in the late

parasitoids [PDF]

open access: yes, 2021
Molecular identification is increasingly used to speed up biodiversity surveys and laboratory experiments. However, many groups of organisms cannot be reliably identified using standard databases such as GenBank or BOLD due to lack of sequenced voucher ...

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

PARASITOIDS AND HYPERPARASITOIDS OF APHELINIDS (HYMENOPTERA: APHELINIDAE) ASSOCIATED WITH ARMORED SCALE, SOFT SCALE INSECTS (HEMIPTERA: COCCOIDEA) AND WHITEFLIES ( HEMIPTERA: ALYERODOIDEA) ON OLIVE IN EGYPT [PDF]

open access: yesJournal of Plant Protection and Pathology, 2015
Aphelinids (Hymenoptera : Aphelinidae) are  the most important  parasitoids of, armored scale, soft scale insects ( Hemiptera: Coccoidea )   and whiteflies ( Hemiptera: Alyerodoidea).

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

open access: yesBiological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

An exotic parasitoid provides an invasional lifeline for native parasitoids

open access: yesEcology and Evolution, 2016
AbstractThe introduction of an exotic species may alter food webs within the ecosystem and significantly affect the biodiversity of indigenous species at different trophic levels. It has been postulated that recent introduction of the brown marmorated stinkbug (Halyomorpha halys (Stål)) represents an evolutionary trap for native parasitoids, as they ...
