, 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

Hyperparasitoids use herbivore-induced plant volatiles to locate their parasitoid host.
PLoS Biology, 2012 Plants respond to herbivory with the emission of induced plant volatiles. These volatiles may attract parasitic wasps (parasitoids) that attack the herbivores. Although in this sense the emission of volatiles has been hypothesized to be beneficial to the

Assessing Predator Activity on Clay Models in Response to Common Insecticides in Turfgrass
Entomologia Experimentalis et Applicata, EarlyView.Insecticides exhibited clear but time‐dependent effects on predatory activity, as reflected by impression types and density on clay models in turfgrass. Certain insecticides (bifenthrin, and in some cases acephate + imidacloprid, imidacloprid, chlorantraniliprole, and tetraniliprole) reduced total impressions shortly after application and again later ...

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

Entomologia Experimentalis et Applicata, EarlyView.Female parasitoids can lower competitive costs by detecting rival‐species cues on shared host fruits (host habitats). We compared native Doryctobracon areolatus and introduced Diachasmimorpha longicaudata on guava fruits infested with Anastrepha fraterculus.

Florida Entomologist, 2012 ABSTRACT Numerous cases of associations of encyrtid wasps with ants have already been reported. In the majority of these cases, however, wasps are associated only indirectly with ants (interference associations) through primary parasitism of the trophobionts (Coccoidea), which are exploited and protected by ants.

Larval parasitoids and pathogens of the groundnut leaf miner, Aproaerema modicella (Lep.: Gelechiidae), in India [PDF]
, 1992 Natural enemies of the groundnut leaf miner,Aproaerema modicella (Deventer), were studied at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) located near Hyderabad in peninsular India.

Ecological Entomology, EarlyView.Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.
