The behavioural responses of parasitic wasps to chemical cues from their hosts and host plants are known to be affected by genetic and environmental components. In a previous study of the codling moth ectoparasitoid Hyssopus pallidus, we found that the response of adult parasitoids to the frass of their host caterpillars depended on a learning process involving plant cues. In the present study, we investigated how and when learning takes place. A series of experiments was conducted involving exposure of parasitoids to fruit cues at different developmental stages. While parasitoids were not able to learn the fruit cues in the adult stage, exposure to fruit odour at early preimaginal stages significantly increased the adult response to frass from fruit-fed caterpillars. The olfactory memory persisted through metamorphosis, with a retention time of 14 days. Preimaginal learning was not confined to fruit cues but was also demonstrated for a host-and fruit-independent cue, menthol. Parasitoids exposed to menthol odour at the egg and larval stages no longer showed negative responses as adults. Sensitization to fruit cues and habituation to menthol are considered to be the mechanisms involved. This study provides evidence of true preimaginal learning of olfactory cues in a parasitic wasp.

“…Several Cotesia species can innately respond to the host-infested plant volatiles and learn to associate the induced volatiles with a host (Cotesia marginiventris, Turlings et al, 1993;Cotesia glomerata, Geervliet et al, 1998). Fujiwara et al (2000b) previously reported that C. kariyai changed their innate preference between two blends of volatiles emitted from different plant species infested with the host larvae through preference learning. However, detailed understanding of the ability for learning this wasp remains elusive.…”

The ability to learn plant volatiles in Cotesia kariyai females was examined by wind tunnel bioassays. Searching experience on a host‐infested corn plant increased subsequent flight responses of females to the infested plant. Females experiencing host by‐products together with the volatiles extracted from infested leaves one time showed an increased response. However, such behavioral changes were not observed in females which experienced only the host by‐products or the volatiles. Thus, the increased response is considered to be preference learning. Multiple experiences of C. kariyai with host by‐products together with the volatiles did not increase their flight response to the volatiles. Furthermore, this learned response gradually decreased within 2 days. These behavioral modifications based on experience would be advantageous for C. kariyai to locate their polyphagous hosts efficiently.

“…This acquired feeding inhibition implies that in a patch containing superior sugars such as glucose, sucrose or fructose, parasitoids rapidly give up the lesser quality food in favor of foraging for the nutritionally superior sugars. Similarly, parasitoids effectively discriminate between hosts in and among patches containing different qualities of hosts, and they change host acceptance based on previous experience (Papaj and Vet, 1990;Poolman Simons et al, 1992;Geervliet et al, 1998;Duan and Messing, 1999;Fujiwara et al, 2000). Surprisingly, also in the case of fructose we see a pronounced reduction in feeding time following exposure to glucose or sucrose; this phenomenon was consistently observed in multiple experiments and with both colonies of M. croceipes.…”

We examined gustatory responses of the larval parasitoid Microplitis croceipes to determine whether the adults discriminate among common sugars, including fructose, glucose, maltose and sucrose, found in plants. When given single sugar solutions of sucrose, glucose, fructose and maltose at concentrations of 0.008-2.0 mol l −1 , the estimated concentrations at which 50% of wasps initiated feeding ranged between 0.054 and 0.085 mol l −1 for sucrose, glucose and fructose, which was significantly lower than for maltose. Wasps showed a strong decrease in feeding time for maltose or fructose following a brief exposure to other sugars, suggesting that wasps can distinguish maltose and fructose from the other sugars tested. The higher acceptance threshold and short feeding time in the case of maltose appears adaptive in light of the relatively poor nutritional quality of the sugar in the longevity trial. The pronounced feeding inhibition seen for fructose following exposure to other sugars is not linked with lower nutritional performance. This feeding inhibition was even seen in wasps that had fed on glucose at the lowest acceptance threshold (0.031 mol l ) and persisted for 24 h. This study is the first to show feeding inhibition of otherwise phagostimulant sugars such as maltose and fructose after gustatory stimulation on other sugars.
