Contrasting effects of climate warming on hosts and parasitoids: insights from Rocky Mountain aspen leaf miners and their parasitoids

open access: yes
Funding: This work was supported by a National Science Foundation postdoctoral fellowship to AAS (DBI-1807694), and a grant from MPG North to HAW & AAS.Because temperature has pervasive effects on biological rates, climate warming may alter the outcomes ...

Parasitoid speciation and diversification

open access: yesCurrent Opinion in Insect Science
Parasitoid wasps may well be the most species-rich animal group on Earth, and host-parasitoid interactions may thereby be one of the most common types of species interactions. Understanding the major mechanisms underlying diversification in parasitoids should be a high priority, not the least in order to predict consequences from high extinction rates ...

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

TACHINID PARASITOIDS: ARE THEY KOINOBIONTS?

open access: yes, 2009
Parasitoids have been divided by Askew and Shaw (1986) into koinobionts and idiobionts, on the basis of whether they allow their host to be mobile and continue developing after oviposition (koinobionts) or paralyze or kill the host before the egg hatches

Maize landraces recruit egg and larval parasitoids in response to egg deposition by a herbivore

open access: yes, 2011
Natural enemies respond to herbivore-induced plant volatiles (HIPVs), but an often overlooked aspect is that there may be genotypic variation in these 'indirect' plant defence traits within plant species.

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

open access: yesJournal of Animal Ecology, EarlyView.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

Natural enemies associated to aphids in peach orchards in Araucária, Paraná, Brazil Inimigos naturais associados a afídeos em pomares de pessegueiros em Araucária, Estado do Paraná, Brasil

open access: yesBrazilian Journal of Biology, 2012
Natural enemies of the Class Insecta are important agents in the balance of aphid populations and an alternative to using insecticides to control these insects.

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

The effect of the aphid sex pheromone on the aphid Myzus persicae and its parasitoid Aphidius colemani

open access: yes, 2012
Aphids remain an enormous threat to the sustainability of crops in glasshouse and field environments around the world. It is known that the aphid sex pheromone is used as a kairomone by its natural enemies, such as parasitoids. The focus of this research

The influence of aphids and honeydew on the leaving rate of searching aphid parasitoids from wheat plants

open access: yes, 1992
Dispersal cages were used to investigate the effects of aphids and treatment with artificial honeydew on the leaving rate of searching females of the parasitoid Aphidius rhopalosiphi from groups of wheat plants. Parasitoids which flew away from groups of
