Expression differences in Aphidius ervi (Hymenoptera: Braconidae) females reared on different aphid host species
The molecular mechanisms that allow generalist parasitoids to exploit many, often very distinct hosts are practically unknown. The wasp Aphidius ervi, a generalist koinobiont parasitoid of aphids, was introduced from Europe into Chile in the late 1970s to control agriculturally important aphid species. A recent study showed significant differences in host preference and host acceptance (infecti...

متن کاملMorphological variation of Aphidius ervi Haliday (Hymenoptera: Braconidae) associated with different aphid hosts
BACKGROUND Parasitoids are frequently used in biological control due to the fact that they are considered host specific and highly efficient at attacking their hosts. As they spend a significant part of their life cycle within their hosts, feeding habits and life history of their host can promote specialization via host-race formation (sequential radiation). The specialized host races from diff...
متن کاملOlfactory conditioning in mate searching by the parasitoid Aphidius ervi (Hymenoptera: Braconidae).
Despite the fact that insect learning capacity has been broadly demonstrated, the role that this process plays during mate searching has been scarcely explored. We studied whether the sexual behaviour of a male parasitic wasp can be conditioned to the odours from two alternative host plant complexes (HPCs) present during its first copulation. The experimental subjects were newly emerged males o...
متن کاملGreenhouse Trials of Aphidius Colemani (hymenoptera: Braconidae) Banker Plants for Control of Aphids (hemiptera: Aphididae) in Greenhouse Spring Floral Crops
Banker plants with Aphidius colemani Viereck were tested in greenhouses in Massachusetts and New York for control of cotton aphid Aphis gossypii Glover, and green peach aphid Myzus persicae (Sulzer) on 2 spring flower crops, pansies ( Viola tricolor hortensis ) and Marguerite daisies ( Argyranthemum hybrid). Banker plants consisted of pots of barley plants infested with the bird cherry-oat aphi...
