摘要:

 【Objective】 The objective of the current study was to explore some biological control methods against Plutella xylostella (L.). 【Method】 The efficiency of extracts taken from 10 different plants (belonging to families meliaceae, annonaceae, sapindaceae and primulaceae) in preventing the oviposition in Plutella xylostella (L.) adults have been observed under laboratory conditions. 【Result】 The average oviposition deterrent rates of Plutella xylostella (L.). adults treated for 48 hour with extracts of Melia sinica, Toona sinensis (leaf),Annona squamosa, A. terapetala and Lysimachia foenum-graecum were 86.21, 94.69, 97.92, 98.91 and 100.00%, respectively. 【Conclusion】 Five plants, viz., Melia sinica, Toona sinensis (leaf),Annona squamosa, A. terapetala and Lysimachia foenum-graecum were found to have the best control effects on oviposition of Plutella xylostella  ( L.) adults, and they have broad application prospects and exploration potential as biological control agents against vegetable pests.
