摘要：

We evaluated the influence of prior ovipositional experience on host selection in four solitary parasitoids. Aphidius ervi Haliday, A. pisivorus Smith, A. smithi Sharma & Subba Rao, and Praon pequodorum Viereck (Hymenoptera: Aphidiidae). When provided simultaneously with equal numbers of two species of aphids, Acyrthosiphon pisum (Harris) and Macrosiphum creelii Davis (Homoptera: Aphididae), all four parasitoids showed a moderate to strong preference for A. pisum. This preference did not increase after sampling, except in P. pequodorum. Learning did not alter host selection behavior in A. ervi and P. pequodorum. However, females of A. pisivorus conditioned on A. pisum selected fewer M. creelii than unconditioned wasps and wasps conditioned on M. creelii. It is suggested that prior ovipositional experience influences a parasitoid's expectations of the kinds of hosts available, but it does not alter the (innate) rank order of hosts.
