摘要
为筛选出更加有效的杀螨植物,采用玻片浸渍法测定了20种植物的乙醇提取物对桔全爪螨的生物活性,结果表明,石椒草、臭灵丹、香茶菜和葎草对桔全爪螨有明显的触杀作用,LC50分别为0.9241、0.9827、0.9905、1.0196 mg.mL-1。这4种植物的杀卵活性测定表明,石椒草具有显著的杀卵作用,0.008 g.mL-1杀卵率达91.87%,其杀卵LC50为1.7032 mg.mL-1。
The bioactivities of ethanol extracts from twenty plants against Panonychus citri were measured in the laboratory with the glass plate dipping to find the strongest acaricidal plant.The results demostrated that Boenninghausenia sessilicarpa,Laggera pterodont,Humulus scanden and Rabdosia of ethanol extracts,of which LC50 were 0.9241,0.9827,0.9905 and 1.0196 mg·mL-1,respectively.The extracts of B.sessilicarpa possessed significantly ovicidal activity four extracts,of which LC50 was 1.7032 mg·mL^-1.
