Learning of an olfactory stimulus associated with a host microhabitat by Exeristes roborator

Abstract: Females of the polyphagous, ectoparasitoid, Exeristes roborator (F.) (Hymenoptera: Ichneumonidae), learned an olfactory stimulus associated with an artificial host microhabitat in the laboratory. In a two‐choice olfactometer, females previously given hosts only in association with one stimulus showed a greater tendency to visit exclusively, and spend time in, chambers containing a source of that stimulus, than control females. Learning of olfactory cues could act in conjunction with learning of visual cues to … Show more

“…The completeness of information is considered of primary importance for female parasitic wasps in order to evaluate the profitability of its environment (Vet et al 1998). This notion is also in accordance with the above-mentioned results for E. roborator, which also only received the negative experience (Wardle and Borden 1989). It is safe to conclude that C. marginiventris' innate response is not affected by an unrewarding response, but it remains possible that increased preference for an odor after a positive experience can be neutralized by an unrewarding experience with the same odor.…”

“…This ectoparasitoid shows no decrease in responsiveness after several exposures to highly attractive apple scent without encountering hosts (Wardle and Borden 1989). However, the behavior of C. marginiventris seems to contrast with that of other parasitoids.…”

“…Both host and host habitat characteristics can be learned when a parasitoid has a contact experience with host, host products, or host plants (Turlings et al, 1989;Lewis and Tumlinson, 1988;Hérard et al, 1988;Lewis et al, 1991;Kester and Barbosa, 1991;Cortesero and Monge, 1994) or oviposition experiences (Vet, 1983;Wardle and Borden, 1989;De Jong and Kaiser, 1991;Wä ckers and Lewis, 1994). Such learning experiences allow parasitoids to adapt to spatial and temporal variations in host availability.…”

“…Many behavioural and ecological data regarding E. roborator are available from biological control studies targeting the species as the controlling agent of the European corn borer Pyrausta nubilalis (Hübner, 1796) (Baker & Jones 1934), the honeycomb moth Galleria melonella Linnaeus, 1758 (Wardle & Borden 1989), the pink bollworm Pectinophora gossypiella (Saunders, 1844), the potato tuber moth Phthorimaea operculella (Zeller, 1873) (Thompson 1975) and the weevil Larinus sturnus Schaller, 1783 (Zwölfer 1974).…”
