棉铃虫 Heliothis armigera(Hubner)是北方棉区的重要害虫,准确的预测预报是综合防治的关键。在成虫诱测方面,当前主要是根据杨树枝把、黑光灯和田间查卵、检查发育进度,根据虫态历期进行预报。这种诱测成虫的方法,比较复杂费力。自1986年引用棉铃虫性信息素(E 型)用于二、三代棉铃虫的测报中,与杨树枝把,黑光灯相比,具有灵敏度高,选择性强,蛾峰明显,使用方便等优点。为了研究棉铃虫性信息素在鲁北棉区测报中的使用价值,于1986年开始,到1988年连续进行三年棉铃虫性信息素在田间诱蛾的试验,今将三年的试验情况和结果总结如下:
Heliothis armigera (Hubner) is an important pest in northern cotton area. Accurate forecasting and forecasting is the key to comprehensive prevention and control. In adult induction, the current main is based on poplar branches, black light and field ovulation, check the progress of development, according to the worm state of the forecast period. This method of inducing adults, more complicated and laborious. Since the introduction of the bollworm sex pheromone (E type) in 1986 for the second and third generations of bollworm, it has the advantages of high sensitivity, strong selectivity, obvious moth peak and easy to use compared with the poplar branches and black light . In order to study the use value of cotton bollworm sex pheromone in the report of the Lubei cotton area, from 1986 to 1988, the sex pheromone of cotton bollworm was tested for three consecutive years in the field. Now the three-year trial and The results are summarized as follows:
