【摘要】 绿色威雷是一种触破式微胶囊杀虫剂。于2001年4月在讷河市保安林场对该杀虫剂防治落叶松毛虫(Dendrolimus superans T.)进行了药效试验。在越冬幼虫上树之前,分别用150,250,350,和450倍药液喷洒落叶松树干,喷洒长度(高度)为1.0, 2.5, 5.5 m。防治结果表明,喷洒150,250,350倍药液取得较为理想的防治效果(幼虫死亡率达97%),450倍液的防治效果为70%幼虫死亡率。绿色威雷杀虫剂可以用作春季防治落叶松毛虫越冬幼虫的一种有效的杀虫剂。推荐使用350倍液和1m的喷洒长度。表1参5。更多还原

【Abstract】 Luseweilei is an easily-bursted microcapsule insecticide. A test of effectiveness of the insecticide to control the larvae of Dendrolimus superans T. was carried out in larch forest in Baoan Forest Farm of Nehe City, Heilongjiang Province, in April 2001. The solutions of different concentrations (1:150, 1:250, 1:350, and 1:450 Luseweilei : water) were sprayed on the larch trunk before the overwintering larvae climbing on trees and the spraying lengths (height) designed were 1.0, 2.5, and 3.5 m high from ground. The control result showed that spraying 150-, 250-, and 350-fold solutions of the insecticide all produced a good control result, with a mortality rate of 97%, but the 450-fold solution only produced 70% mortality. It is concluded that this insecticide can be used as a kind of good insecticide to control the overwintering larvae of D. superans in spring. Spraying 350-fold solution of easy-burst microcapsule insecticide and one meter spraying length are recommended for the future application..更多还原
