Abstract: The oviposition repellency of the alcohol extracts from 50 species of non-preferable plants and azadirachtin against citrus red mite (Panonychus citri) was determined using laboratory bioassays.In choice tests,the extracts from 42 of the 50 plant species and 1% azadirachtin (2000@) significantly reduced oviposition 1d after treatment.The repellency effect of the extracts from the 42 plant species was better than that of azadirachtin.Mikania micrantha extract had the best result,with an Interference Index of Population Control (IIPC) of 0.087 1 d after treatment,and significantly reduced oviposition for 9 d,while the extracts from Sesbania cannabina,Allium tuberosum,Paederia scandens,Duranta erecta and Dicranopteris pedata also had good effects,with an oviposition repellency of over 70% 1 d after treatment,and significantly reduced oviposition for 4~6 d.The effect became weaker as time went on.None of the extracts showed significant oviposition attraction.

Key words: Extract of non-preferable plant, Panonychus citri, Oviposition repellency
