云霄县杨桃果园橘小实蝇的发生动态及防控

Test on the dynamics of Bactrocera dorsalis Hendel in Averrhoa carambola L.orchards of Yunxiao County and its control

调查了云霄县杨桃园橘小实蝇种群的发生动态及不同防治试验方法,并探讨了其防控配套技术。结果表明,4种不同防治方法存在极显著差异,防控效果由高至低分别为:性诱防治+套袋>套袋>化学防治>性诱防治。实践表明,性诱防治+果实套袋能有效防控橘小实蝇发生为害,该配套技术值得推广。

Dynamics of Baccrocera dorsalis Hendel population in Averrhoa carambola L. orchards of Yunxiao County and its different control methods were investigated, and the concerned technology was explored. The results showed that there was an extremely sig- nificant difference between 4 methods of control. The effects of control were as follows according to the sequence from high to low. Sex pheromone ＋ fruit bags 〉 bags 〉 chemicals 〉 sex pheromone. In practice it was proved that sex pheromone ＋ fruit bags could ef- fectively control the damages caused by B. dorsa//s and this series of technology is worth popularization.
