红铃虫性引诱剂(高斯、海克)和红铃虫粗提物,均对红铃虫雄蛾有很高的引诱活性。1976年在第二代红铃虫发蛾期间,我们发现棉小造桥虫Anamis flava Fabricius粗提物也能引诱红铃虫雄蛾,经过大面积诱捕和小区对比试验,说明这种粗提物的效果相当于化学合成性引诱剂和红铃虫粗提物。具体作法是:把从棉田树枝把上诱到的棉小造桥虫雌蛾(不分交配和未交配)剪下腹部末端、用有机溶剂浸渍抽提、将

Red bollworm sex attractants (Gaussian, Heike) and pink bollworm crude extract, are highly attractive to male pink moth Annals activity. In 1976, during the second generation of Helicoverpa armigera, we found that the Anamis flava Fabricius crude extract could also induce the male pink moth, after large-area trapping and community comparative experiments, indicating that this crude extract The effect is equivalent to chemical synthesis attractant and pink bollworm crude extract. The specific approach is: the cotton from the branches of the tree to lure cotton bridge female moths (regardless of mating and unpaired) cut the abdomen end, impregnated with organic solvent extraction, will
