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％。 In this study, we observed the control effect of Agriotas (A24) and Beijing different concentrations and different application methods of Steinernemacarpocapsae nematode on Larvae Anoplophora and Populus simonii larvae. Field experiments showed that the effect of Atractylodes japonica and Beijing strains was better than that of A24 strain, with an injection concentration of 7500 / ml, and the larvae hole reduction rate was 86.4%. The optimum concentration of A14 strain was 10000 per ml for Beijing ten locusts, and the optimal concentration for Beijing strain was 5000 per ml. There was no significant difference in the control effect between the two strains. Considering the economic cost, Beijing strains could be selected, Live larvae hole reduction rate can reach 66.7%.
