摘　　要：本试验观察了Ｓｔｅｉｎｅｒｎｅｍａｃａｒｐｏｃａｐｓａｅ线虫的两个品系Ａｇｒｉｏｔａｓ（Ａ２４）和Ｂｅｉｊｉｎｇ不同浓度及不同的施药方法对光肩星天牛、杨十斑吉丁虫幼虫的防治效果。田间试验表明：对光肩星天牛，Ｂｅｉｊｉｎｇ品系的作用效果优于Ａ２４品系，以注射浓度７５００条／ｍｌ为佳，幼虫孔减退率达８６．４％。对杨十斑吉丁虫，Ａ２４品系最优浓度为１００００条／ｍｌ，Ｂｅｉｊｉｎｇ品系最优浓度为５０００条／ｍｌ，两个品系的防治效果没有显著差异，从经济成本考虑，可选择Ｂｅｉｊｉｎｇ品系，活幼虫孔减退率可达到６６．７％。t Effects of 2 strains of Steinernema Carpocapsae, Agriotas (A24) and Beijing ,on control of Anopiophora glaripennis (Motsch.) and Melanophila Decastigma Fabr. were observed under different concentrations and different application methods. The field test shows that the effect of Beijing was higher than that of A24 on control of Anopiophora glaripennis (Motsch.). The best treatment was injection at a concentration of 7500 nematode/ml and the reduction rate of young insect holes was 86.4%. For control of Melanophila decastigma Fabr. the optimum treatments were 10000 nematode of A24/ml and 5000 nematode of Beijing/ml and there was no difference between the effects of 2 strains.Considering the economic cost Beijing may be chosen and the reduction rate of live young insect holes can reach 66.7%.
