为了探索棉铃虫的性引诱作用,1975年棉铃虫第四、五代发生期间,我们在潜江县三江公社三江大队进行了雌蛾诱杀雄蛾的反复试验,在53天内投放雌蛾171头(319盆次),共诱获雄蛾2,029头,平均每头诱获11.85头。第四、五代发蛾高峰期,每盆次诱蛾量均在20头以上,单盆最高一日的诱蛾量达59头。在试验中我们发现: 1.凌晨3—5时雄蛾趋向诱盆最多,诱获量最大,上半夜和天亮以后则无雄蛾投盆。 2.雌蛾羽化后3—4天,对雄蛾的引诱力最大。 3.每台诱捕器以雌蛾2—3头较为适宜。用量增
In order to explore the sexual attraction of cotton bollworm, during the fourth and fifth generations of the cotton bollworm in 1975, we conducted repeated tests on male moths to kill and kill male moths at the Sanjiang Brigade of Sanjiang Commune, Qianjiang County. 171 female moths (319 A total of 2,029 male moths were obtained, with an average of 11.85 individuals per head. In the fourth and fifth generation of hair moths, the amount of moths in each pot was more than 20, and the maximum amount of moths in single pot was 59. In the experiment we found: 1. 3-5 o’clock male moths tend to induce the most, the largest amount of seizures, the middle of the night and after dawn, no male moths cast pots. Females 3-4 days after eclosion, the largest attraction for male moths. 3. Each trap to females 2-3 head more appropriate. Increased use
