黄斑长翅卷蛾性信息素测报与诱捕作用研究

Effect of Forecasting and Trapping of Sex Pheromone in Acleris Fimbriana (Lepidoptera: Tortricidae)

黄斑长翅卷蛾是我国北方果园的重要害虫。研究了利用性信息素在桃园与苹果园对第一代夏型黄斑长翅卷蛾的预测预报及诱捕作用,结果表明,在桃园和苹果园其诱捕数量与田间成虫羽化规律及雄虫的羽化动态表现一致,在桃园和苹果园诱捕量与雄虫羽化数相关系数分别达0.968和0.982。测报结果还表明,黄斑卷叶蛾第一代成虫羽化高峰期在桃园比苹果园早,因此利用性信息素测报与防治黄斑长翅卷蛾在果园的无公害治理中具有良好前景。

<Abstrcat> The yellow tortrix,Acleris fimbriana is an economically important orchard insect in northern Chinese.Forecasting and trapping effects of sex pheromone for the 1^(st) generation summer-biotype adults were studied in peach and apple orchard. The results showed that the dynamic rule of trapping adults was the same with those of eclosion adults and eclosion males in the field. The positive correlation coefficient were 0.968 and 0.982 between numbers of trapping and eclosion males in peach and apple orchards, individually. The result indicated that eclosion peak time of adults were earlier in peach orchard than apple orchard. The sex pheromone could be regarded as an effective method for forecasting and controlling the yellow tortrix.
