Habitat fragmentation may interrupt trophic interactions if herbivores and their specific parasitoids respond differently to decreasing connectivity of populations. Theoretical models predict that species at higher trophic levels are more negatively affected by isolation than lower trophic level species. By combining ecological data with genetic information from microsatellite markers we tested...
Baculoviruses may interact with parasitoids in the same host. A previous study has shown that infection of larvae with Spodoptera litura nucleopolyhedrovirus (SpltNPV) was deleterious to the survival and development of Meteorus pulchricornis (Wesmael) (Hymenoptera: Braconidae). In this paper, the interactions between M. pulchricornis and Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) ...
Background and purpose: One of the most popular methods to control the synanthropic flies is using parasitoid wasps. The aim of this study was to estimate the experimental parasitism rates of pupae of Musca domestica, Lucilia sericata, and Sarcophaga heamorrhoidalis by parasitoid wasps, including Nasonia vitripennis, Spalangia nigroaenea, and Pachycrepoideus vindemmiae. Materials and methods: ...
In order to study the parasitoid flies of Sunn pest in Isfahan, this research was conducted during the years 1997-1998. The results indicated that the dominant species of parasitoid fly is Phasia subcoleoptrata L. This species has two generations per year and over winters as pupae in soil under the shrubs of aestivation and hibernation places of Sunn pest and remains there until the following s...
Insect parasitoids have evolved symbiotic interactions with several viruses and thousands of parasitoid species established mutualistic associations polydnaviruses (PDVs). While PDVs often been described as virulence factors allowing development immature inside their herbivore hosts, there is increasing awareness that can affect plant–insect interactions. We review recent literature showing alt...
Crop pests are a permanent threat to horticultural production. Several control methods recommended for their control, including biological control. This method based on the use of natural enemies is not well established. The objective this study was assess diversity and abundance crop pests. A survey crops associated with carried out 144 fields in southern Senegal measure various pests, determi...
Behavioral tactics play a crucial role in the evolution of species and are likely to be found in host-parasitoid interactions where host quality may differ between host developmental stages. We investigated foraging decisions, parasitism and related fitness in a gregarious ectoparasitoid, Sclerodermus harmandi in relation to two distinct host developmental stages: larvae and pupae. Two colonies...
