| 摘 要： | 两年一代落叶松毛虫的防治是个新课题。为更有效的控制其危害，寻找新的杀虫剂势在必行。合力灵是一种新有机磷杀虫剂。经对落叶松毛虫的毒力测定和室内外的药效测定得出：１．５％和３．０％的合力灵制剂对５龄以下落叶志虫幼虫有良好的防治效果，７２ｈ杀虫死亡率分别为９４．６％和９７．３％。１．５％合力灵对４龄叶松毛虫幼虫的致死中量为３２．３０ｍｇ／ｋｇ。研究表明合力灵在防治两年一代落叶松毛虫幼虫上大有前途，可以在

| Abstract: | Heliling is a new organic phosphorus pesticide. Its toxicity assay was made on Dendrolimus superans that completes 1 generation in 2 years in the forest area of Inner Mongolia. 1.5% and 3% of Heliling chemical were used to control the larvae of 4th instar or younger. The mortality at 72 h was 94.6% and 97% respectively. The LD50 of 1.5% Heliling against the 4th instar was 32.30 mg. It was suggested that the chemical could be put into practical use for controlling the larvae of D. Superans having 1 generation in 2 years. |
