[目的]探索广西南宁地区桔小实蝇的为害与发生规律及综合防治方法。[方法]在番石榴园采用定点系统调查法,以实蝇引诱剂为材料对桔小实蝇成虫发生动态进行调查;研究诱蝇剂、果实套袋、清园捡拾落果、适时喷药等方法对该虫害的防治效果。[结果]桔小实蝇在广西南宁有2个为害高峰期(5～6月、8～9月)。通过诱蝇剂诱杀雄虫、适时喷药、套袋、清园捡拾落果等综合防治措施,番石榴园的虫口密度大幅下降。2008年6月桔小实蝇为害高峰期,科研基地番石榴为害率仅为6.67%～7.33%,而对照区为90.53%～98.00%,防治效果显著。[结论]研究结果不仅初步挽回了番石榴产量的损失,也为在该地区制定防治桔小实蝇的总体策略提供了依据。
[Objective] The research aimed to explore the damage, occurrence and comprehensive prevention and cure of Trichosanthes flies in Nanning, Guangxi. [Method] The investigation on the dynamics of adult adults of Drosophila melanogaster was carried out in the guava garden using the method of fixed-point systematic investigation and the fruit flies attractant as the material. The pest control effect. [Result] There were 2 peak times of damaging fruit fly in Nanning, Guangxi (May - June, August - September). Through the lure of trapping insecticides tracheids, timely spraying, bagging, picking up and falling garden and other integrated control measures, guava garden pest population density dropped significantly. In June 2008, the damage rate of guinea-pig fruit flies was only 6.67% -7.33% in the research base while that in the control area was 90.53% -98.00%. The control effect was remarkable. [Conclusion] The results not only initially restored the loss of the yield of guava, but also provided the basis for formulating the overall strategy of preventing and controlling the fruit fly of the fruit fly in the region.
