广西番石榴园桔小实蝇综合防治研究

[目的]探索广西南宁地区桔小实蝇的为害特点、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）。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实施后,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整体策略提供了依据。
