通过在枣林中的系统调查与试验研究,明确了枣镰翅小卷蛾(AncylissafivaLiu)成虫趋向其性信息素的行为及利用性信息素诱捕成虫的时辰节律;大面积诱杀对枣林中这种害虫种群的控制作用。应用性信息素引诱枣镰翅小卷蛾成虫有两个高峰期,第1个在4:00~6:00,其累计诱杀率为37%~76%,第2个在18:00~22:00,其累计诱杀率为15%左右。性信息素引诱不仅影响成虫的求偶及交配行为,同时也干扰了成虫的取食、扩散与隐蔽情况下的飞行活动。大面积枣林中诱杀防治试验结果表明,诱杀区与对照区比较,有效卵的减退率为685%~852%。
Through the systematic investigation and experimental study in jujube forest, the behavior of AncylissafivaLiu adult towards pheromone and the hourly rhythm of pheromone trapping adults were clarified. Control of pests and species. Applied pheromone trap juvenile Sclenella larvae adults have two peak, the first 4:00 ~ 6:00, the cumulative trapping rate was 37% to 76%, the second at 18:00 to 22 : 00, the cumulative trapping rate of about 15%. Sex pheromone seduction not only affects the courtship and mate behavior of adult adults, but also interferes with the flight activities of adult worms in the situations of feeding, spreading and concealment. The results of the trapping and controlling experiments on jujube in large area showed that compared with the control area, the rate of effective egg drop was 685% ~ 852%.
