Nymphal and adult performance of Apolygus lucorum (Hemiptera: Miridae) on a preferred host plant, mungbean Vigna radiata

摘要: Mungbean, Vigna radiata (L.) Wilczek, a preferred host plant of Apolygus lucorum (Meyer-Dur) (Hemiptera: Miridae), is used in China as trap crop for this pest cotton fields. Little known, though, about the relationship between adult oviposition preference and offspring performance A. on mungbean. In study, we compared mungbean versus plants both open-field plots field cages. Field-plot experiments demonstrated that population density first instar nymphs ratio to adults were significantly higher than cotton. Choice no-choice cage revealed number eggs laid was We also longevity fecundity, well survival development these two plants. found females survived longer more (P   0.05). summary, consistent with nymphal performance. This study furthers understanding polyphagous species its plants, which will help improve trap-cropping strategies control are based use
