Abstract

Abstract:

Wikstroemia chamedaphne was investigated for its acarocidal activity against Tetranychus viennensis, a serious pest of many crops including apple trees in China. Its active constitutes were extracted,separated and purified. The results indicated that the extraction of petroleum ether from WCME (Wikstroemia chamaedaphne methanol extract) appeared a strong acarocidal activity. The adjusted mortalities of egg,larva and female mite were 74.48%,100.00% and 100.00% respectively, while the LC_(50) values were 2.106 2、0.304 1 and 0.771 6 mg·mL^-1 respectively.

Key words: Wikstroemia chamedaphne, Tetranychus viennensis, extract, purify
