亚洲玉米螟(Ostrinia furnacalis)是我县玉米上常发性害虫,常年发生14万亩左右,约占播种面积的51%,严重影响玉米的产量,且近几年其发生有上升趋势。为搞玉米螟的测报和防治,我站自1986—1991年进行了玉米螟性诱剂亦即性信息素的诱蛾和测报研究,表现出简单易行,诱蛾效果好,能准确反应出蛾量消长情况,现将6年研究结果,总结如下:一、材料和方法1.性诱剂来源:为江苏金坛激素研究所合成并制成以聚乙稀为载体的空心管,由省植保站提供;2.诱捕器制作:用盆口直径为30cm、深
Ostrinia furnacalis, an insect pest on maize in our county, has a perennial pest of about 140,000 mu, accounting for about 51% of the sown area, seriously affecting the yield of maize and its occurrence has been on the rise in recent years. In order to test the corn borer and its prevention and control, from 1986 to 1991, I conducted a study on the trapping and reporting of the sex pheromone of the female corn borer, which is simple and easy to be carried out and has the effect of attracting moths accurately and accurately Moth quantity and growth, now 6 years of research results, summarized as follows: I. Materials and methods 1. Sex Attractant Source: Jiangsu Jintan Institute of hormone synthesis and made of polyethylene as a hollow tube carrier by the provincial Plant protection station to provide; 2 trap production: with a basin diameter of 30cm, deep
