摘要: Mungbean, Vigna radiata (L.) Wilczek, a preferred host plant of Apolygus lucorum (Meyer-Dur) (Hemiptera: Miridae), is used in China as a trap crop for this pest in cotton fields. Little is known, though, about the relationship between adult oviposition preference and offspring performance of A. lucorum on mungbean. In this study, we compared the oviposition preference of A. lucorum on mungbean versus cotton plants in both open-field plots and field cages. Field-plot experiments demonstrated that the population density of first instar nymphs of A. lucorum and the ratio of first instar nymphs to adults were significantly higher on mungbean than on cotton. Choice and no-choice cage experiments revealed that the number of eggs laid on mungbean was significantly higher than on cotton. We also compared adult longevity and fecundity, as well as offspring survival and development on these two host plants. We found that A. lucorum adult females survived longer and laid more eggs on mungbean than on cotton (P < 0.05). Mungbean also promoted higher rates of development than did cotton (P < 0.05), but did not affect nymphal survival (P > 0.05). In summary, the preference of A. lucorum adults for mungbean is consistent with both adult and nymphal performance. This study furthers the understanding of the relationship between the polyphagous species A. lucorum and its host plants, which will help improve trap-cropping strategies for the control of A. lucorum that are based on the use of mungbean.
