性诱是近年来推广的一项治虫新技术.去年春,我们首次在吐鲁进行性诱杀春尺蠖的试验,初获成效.一、性诱器的制作一种方法是:将窗纱剪成6.5×11厘米的小块,卷成手指粗细的管,接缝勾牢,一端用小块纱盖封口,一端以纸卷塞住,即成小纱笼.然后,到春尺蠖严重发生处,在树干及树缝中捕捉雌峨,每笼5—10头,再将其架在有小棍支撑的碗上.碗中盛水,水中加一点洗衣粉或草木灰,这样即成纱笼式诱扑器,用来诱扑雌蛾.也可将火柴盒戳成许多小孔代替小纱笼.也可直接把雌蛾用大头针钉在高粱秆上,然后架在水碗上,但诱扑效果稍差.
Sex trapping is a new pest control technology promoted in recent years. Last spring, we conducted the first sexual trapping in Tulu spring prickly heat test, the initial success. One, sex traps produced a method is: the screen cut 6.5 × 11 cm small pieces, rolled into the thickness of the fingers of the tube, the joints seized, one end sealed with a small yarn cover, one end of the paper roll plug, that is, a small sarong. And tree seams to capture the herons, each cage 5 to 10 head, and then its stand in a small stick support bowl on bowl water, add a little detergent or ash in the water, Used to lure female moth.Also can be poked into a lot of small holes in the box instead of a small yarn cage.At the same time, the female moths can also be pinned directly on the sorghum stalks, and then racked on the water bowl, but the effect is less effective.
