Analytical model to predict the number of parasitoids that should be released to control diamondback moth larvae in greenhouses

Abstract

When using parasitoids in biological control programs, it is important to understand the number of parasitoids required for release to maintain pest population under economic injury levels. Here, we developed an analytical model to estimate the number, and apply the model to a system involving crucifer plants (Brassica rapa), diamondback moth [Plutella xylostella (L.) (Lepidoptera: Plutellidae)] (DBM) larvae, and the parasitoids Cotesia vestalis (Haliday) (Hymenoptera: Braconidae). To evaluate the calculated number of C. vestalis for release, we conducted the evaluation of our previously reported study by Abe et al. © 2011 Taylor & Francis.
