通过两年的田间试验，明确了棉铃虫（ＨｅｌｉｃｏｖｅｒｐａａｒｍｉｇｅｒａＨ．）性诱剂可大量诱杀棉铃虫雄成虫，每枚诱芯越冬代可诱３３头，一代３７０头，二代９２头，三代５６１头；可使田间落卵量减少８．６％～３１．３％，卵孵化率降低１．２％～８；２％，虫口密度降低１９．０％～４５．７％。本文还优选出了较好的棉铃虫性诱剂型号和比较了棉铃虫性诱剂与高压汞灯的防效。 Through two years of field experiments, it was clear that Helicoverpa armigera sexual attractants could induce large numbers of male adults of Helicoverpa armigera, each of which attracted 33 heads, 370 heads of generation, 92 of the second generation and 561 of the third generation. Can reduce the amount of eggs shed in the field 8.6% ~ 31.3%, egg hatching rate decreased 1.2% ~ 8; 2%, population density decreased 19.0% ~ 45.7%. In this paper, we also give a better model of cotton bollworm sex attractant and compare the control efficacy of the cotton bollworm sex attractant and high pressure mercury lamp.
