齐齐哈尔半干旱地区虫情测报灯诱集昆虫试验

Experiment for Trapping Insects by Pests Forecasting Lamp in Semiarid Regions of Qiqihar

通过在齐齐哈尔半干旱地区使用自动虫情灯诱集昆虫试验,结果表明,在试验区,鳞翅目、双翅目和同翅目昆虫占绝对优势;诱集到的昆虫中,森林害虫和农业害虫占较大比例,其中草地螟(Loxostege sticticalis Linne)数量最多,3年中共诱集到17 500头,占总诱集数量的31.15%;诱集害虫的同时也诱集到一些益虫,但数量不足以影响生态平衡。因此,使用自动虫情测报灯具有良好的害虫诱集效果。

Experiment for trapping insects by automatic pests forecasting lamp in semiarid regions of Qiqihar were conducted. Result shows that.. Lepidoptera, Diptera and Homopterans are dominant; among trapped insects, forest pests ＆ agricultural pests accounted for a large proportion,among which Loxostege sticticalis have the largest number. The total number of traps are 17,500 in three years,accounting for 31. 15% of all numbers of trapping ; while trapping pests some beneficial insects were also trapped;but the number is not sufficient to affect ecological balance. Therefore, the use of automatic pests forecasting lamps has optimal pest trapping effect.
