Bt rice does not disrupt the host-searching behavior of the parasitoid Cotesia chilonis
We determined whether plant volatiles help explain why Cotesia chilonis (a parasitoid of the target pest Chilo suppressalis) is less abundant in Bt than in non-Bt rice fields. Olfactometer studies revealed that C. chilonis females responded similarly to undamaged Bt and non-Bt rice plants. Parasitoids preferred rice plants damaged by 3(rd)-instar larvae of C. suppressalis, but did not different...
متن کاملApparent Acquired Resistance by a Weevil to Its Parasitoid Is Influenced by Host Plant
Field parasitism rates of the Argentine stem weevil Listronotus bonariensis (Kuschel; Coleoptera: Curculionidae) by Microctonus hyperodae Loan (Hymenoptera: Braconidae) are known to vary according to different host Lolium species that also differ in ploidy. To further investigate this, a laboratory study was conducted to examine parasitism rates on tetraploid Italian Lolium multiflorum, diploid...
متن کاملGenetic Diversity and Host Alternation of the Egg Parasitoid Ooencyrtus pityocampae between the Pine Processionary Moth and the Caper Bug
The increased use of molecular tools for species identification in recent decades revealed that each of many apparently generalist parasitoids are actually a complex of morphologically similar congeners, most of which have a rather narrow host range. Ooencyrtus pityocampae (OP), an important egg parasitoid of the pine processionary moth (PPM), is considered a generalist parasitoid. OP emerges f...
متن کاملA host-parasitoid interaction with Allee effects on the host
We explore the addition of Allee effects to single-species discrete-time models with overcompensatory density dependence. When the intrinsic growth rate of the population, r , is large, the population bifurcates into chaos. The population goes extinct if r is either below a threshold level or very large. The model is then used to study host–parasitoid interactions with and without Allee effects...
متن کاملHost-Parasitoid Systems with Predation-Driven Allee effects in Host
4 Allee effects and parasitism are common biological phenomena observed in nature, which are believed to have significant impacts in ecological conservation programs. In this article, we investigate the population dynamics of host-parasitoid systems with Allee effects induced by predation satiation in host to study the effects of Allee effects and parasitism as well as the timing of parasite’s ...
