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...

fauna of the the aphid parasitoids at southern parts of the zagros submountains, and their host associations have been investigated. a total of 24 parasitoid species were identified in association with 30 aphids on 36 host plant species, representing more than 80 tritrophic associations (parasitoid-aphid-plant). aphidius avenae haliday is newly reported from iran. generally, the area of souther...

The tea aphid ( Toxoptera aurantii Boyer de Fonscolombe) is an important plant pest insect worldwide. parasitoid wasp, Aphelinus sp., one of the most natural enemies in China. Unfortunately, sp. alone cannot effectively control outbreaks under conditions. In this study, 27 volatile compounds from aphid-injured shoots, flowers, sex pheromones, or body rinses were selected and tested Y-tube olfac...

Endosymbiotic bacteria in the genus Wolbachia have been linked to several types of reproductive parasitism, which enhance their own transmission, while their direct effects on the host vary from beneficial to neutral or detrimental. Here, we report negative effects of infection on immunity-related traits of Drosophila simulans and the parasitoid wasp Leptopilina heterotoma. Infected D. simulans...

Millions of years of co-evolution have driven parasites to display very complex and exquisite strategies to manipulate the behaviour of their hosts. However, although parasite-induced behavioural manipulation is a widespread phenomenon, the underlying neuronal mechanisms are only now beginning to be deciphered. Here, we review recent advancements in the study of the mechanisms by which parasito...

Combining a variety of large-scale, data-intensive techniques, a recent study has unraveled the neural pathways involved in Drosophila larval escape from a parasitoid wasp invasion.

Aprostocetus exertus La Salle (Hymenoptera: Eulophidae: Tetrastichinae) is described as a parasitoid of the invasive Erythrina Gall Wasp, Quadrastichus erythrinae Kim (Hymenoptera: Eulophidae: Tetrastichinae). The description is based on material originally collected in Tanzania and South Africa. This species is described because of its potential as a biological control agent against the Erythr...

Objective: In this study the efficacy of two agent of this biological control agent of corn stem borer in corn fields compared with common synthetic insecticides Endosolfan to find a suitable alternative for chemical control of pests in corn fields. Methods: In order to evaluate the efficiency of biocontrol agents of corn stem borer ,Ostrinia nubilalis, experiment was conducted in a ra...

Parasitoid diversity in terrestrial ecosystems is enormous. However, ecological processes underpinning their evolutionary diversification in association with other trophic groups are still unclear. Specialisation and interdependencies among chalcid wasps that reproduce on Ficus presents an opportunity to investigate the ecology of a multi-trophic system that includes parasitoids. Here we estima...
