不同诱源对梨小食心虫引诱效果的研究

采用多种引诱剂对桃园梨小食心虫的防治进行研究,结果表明,性信息素对梨小食心虫的防治效果优于糖醋酒液、果汁、频振灯和黑光灯。比较5个厂家性诱芯结果表明,E厂家诱芯诱捕效果最好,日诱捕量可达(172.3±10.2)头;B,C,D厂家诱芯差异不显著,且B厂家诱芯稳定性较差;A厂家诱芯诱捕效果最差。2枚诱芯诱捕量强于1枚诱芯,是1枚诱芯的1.98倍。并讨论了几种诱源的诱效原因及其应用潜力。

Study on the Effects of Several Attractants to Gapholitha molesta

Oriental Fruit Moth, Gapholitha molesta, which is one of the major pests of fruit trees. Several attraetants were tested at peach orchard in Taigu County, Shanxi Province. The results shows that the sex pheromone of oriental fruit moth has the best control effect, much better than mixtures of sugar-acetic acid-ethanol, fruit juice, vibration frequency light and blacklight light. Comparison of sex pheromone cores provided by 5 manufacturers, the results indicates that E trapping amount is up to 172.3 ＋ 10.2 and has the best attracting effect. B, C and D products show no significant difference. During the test, B core has poor stability, A core gets the worst trapping effect, and 2-core trapping amount is higher than 1-core, is 1.98 times of one core. Finally, we discussed reasons of the effect of several induced sources and their applications potentiality.
