昆虫病原线虫对鞭角华扁叶蜂致死能力的测定

Infectivity of Chinolyda flagellicornis by Steinernema

选用斯氏线虫科的 ８ 个品系对鞭角华扁叶蜂幼虫致死能力测定结果表明， Ａ２４和 Ｄ－ ４－ ３ 品系对该叶蜂幼虫具有较强的致死能力。室内沙接法试验，３ 天后校正致死率可达 ７０％和 ６５１％ ；并用 Ａ２４品系在林间喷雾防治树上幼虫，２ 天后校正致死率达 ６８８％ 。

This paper reports the results of the tests in infectivity of the Steinernema spp. nematodes to Chinolyda flagellicornis . The results have shown that D-4-3 and A 24 the highest infectivity among the eight strains of Steinernema spp. at laborotory and field. The corrected mortality of the larvae was from 70% and 65 1% in a laboratory. When the larvae of C. flagellicornis was controlled by spraying in forests, the corrected mortality of the larvae was 68.8% after 2 days.
