Dynamics of Insects and Their Facultative Defensive Endosymbiotic Bacteria: A Simulation Model. [PDF]
Aphids host endosymbionts protect them against attacks from parasitoids, leading to potential reduction in the efficacy of biological control against these crop pests. We developed a Monte Carlo simulation model to examine changes in levels of endosymbiont infection in an insect population in the presence of parasitoids attacking them over several ...

The success of a habitat specialist biological control agent in the face of disturbance
Natural enemies that can use multiple habitats are thought to better withstand disturbances in agricultural systems than natural enemies that are habitat specialists.

Aphidius ervi venom regulates Buchnera contribution to host nutritional suitability
The association between the pea aphid, Acyrthosiphon pisum (Harris) (Homoptera: Aphididae), and the endophagous parasitoid wasp Aphidius ervi Haliday (Hymenoptera: Braconidae) offers a unique model system for studying the molecular mechanisms underlying the complex interactions between the parasitoid, its host and the associated primary symbiont. Here,

The effects of parasitisation by Aphidius ervi on the feeding behaviour of the aphid Acyrthosiphon pisum were studied. There was progressive increase in the time devoted to xylem ingestion (G waveform) and concomitant decrease in time devoted to phloem ...

Two new aphid parasitoids (Hymenoptera, Braconidae, Aphidiinae) from field crops of South America [PDF]
During two seasons of field sampling in crop fields in Argentina, a total of 2,276 Aphidiinae specimens were collected using Malaise traps positioned in maize, soybean, and wheat fields.

Occurrences of pea aphids and their natural enemies (syrphids, mummies caused by entomopathogenic fungi Beauveria sp. and by the parasitic wasp Aphidius ervi) were compared in monocultures and mixtures of field peas and spring cereals in three seasons ...

Aphid symbionts and endogenous resistance traits mediate competition between rival parasitoids. [PDF]
Insects use endogenous mechanisms and infection with protective symbionts to thwart attacks from natural enemies. Defenses that target specific enemies, however, potentially mediate competition between rivals and thereby impact community composition ...
