| description | Parasitoids searching for polyphagous herbivores can find their hosts in a variety of habitats.
Under this scenario, chemical cues from the host habitat (not related to the host) represent
poor indicators of host location. Hence, it is unlikely that naïve females show a strong
response to host habitat cues, which would become important only if the parasitoids learn to
associate such cues to the host presence. This concept does not consider that habitats can
vary in profitability or host nutritional quality, which according to the optimal foraging theory
and the preference-performance hypothesis (respectively) could shape the way in which
parasitoids make use of chemical cues from the host habitat. We assessed innate preference
in the fruit fly parasitoid Diachasmimorpha longicaudata among chemical cues from
four host habitats (apple, fig, orange and peach) using a Y-tube olfactometer. Contrary to
what was predicted, we found a hierarchic pattern of preference. The parasitism rate realized
on these fruit species and the weight of the host correlates positively, to some extent,
with the preference pattern, whereas preference did not correlate with survival and fecundity
of the progeny. As expected for a parasitoid foraging for generalist hosts, habitat preference
changed markedly depending on their previous experience and the abundance of hosts.
These findings suggest that the pattern of preference for host habitats is attributable to differences
in encounter rate and host quality. Host habitat preference seems to be, however,
quite plastic and easily modified according to the information obtained during foraging. |
