为了探索烟青虫的性引诱作用,我们于1979年烟青虫发生期间,采用笼关活雌蛾水盆诱捕器在本所试验田进行了诱捕雄蛾的反复试验,试验自7月10号开始至9月1号结束,历时51天,共投放活雌蛾37头(102盆次)共诱捕雄蛾925头,平均每头雌蛾诱获25头,发蛾盛期每头雌蛾最高诱捕量为333头,其中一日最高诱捕量为164头。活雌蛾的性诱力平均可使用7.6天,最多可达11天。在本试验中我们发现:1、雄蛾被雌蛾引诱,呈“Z”字型逆风飞向雌蛾被捕。2、晚11时至次日3时是雄蛾趋向诱盆被捕的有效时间,0—3时诱获量最大,占总诱捕
In order to explore the sexual attraction of tobacco budworm, we conducted a trial of trapping male moths in our experimental field during the period of tobacco budworm in 1979 with the cage trap of female moths hanging in the cage, starting from July 10 to September 9 A total of 37 live moths (102 pots) were killed. A total of 925 male moths were trapped, with an average of 25 moths per female. Moths had the highest trapping rate per female moth 333 heads, of which one day the maximum amount of trapping 164 head. The average female sexual attractant can be used for 7.6 days, up to 11 days. In this experiment we found: 1, male moths were lured by female moths, was “Z” shaped headwind flew to the female moth arrested. 2, from 11 pm to 3 pm the next day was the effective time for male moths to get caught in the basin, 0-3 was the largest, accounted for the total trapping
