新诱剂对柑橘大实蝇成虫的诱杀效果

Effects of New Lures on Control of Adult Chinese Citrus Fly

为了探讨新诱剂对柑橘大实蝇的防治效果,研究设计了地面覆草以及添加红糖等辅助措施,对比分析了新诱剂与果瑞特的诱杀效果和经济成本。结果表明,新诱剂对柑橘大实蝇的诱杀效果显著优于果瑞特,其橘园的虫果率仅为果瑞特处理的22.9%,扣除成本后,经济效益比果瑞特处理高209元/667m2;在地面自然长草的橘园,新诱剂的诱杀效果较好,其虫果率比地面没有长草的橘园的虫果率低39.57个百分点;在地面少草的橘园,红糖能显著提高其对柑橘大实蝇的诱杀率,其虫果率比不添加红糖的处理低18.45个百分点。

This study investigated and compared the effectiveness of new lures against Great on the control of adult Chinese citrus fly（Tetradacus cirri Chen）. The results showed that the controlling effect of new lures was better than Great. The rate of affected fruit in thenew lure treated orchards was only 22.9% of the Great treated orchards. The effect of new lures was better in orchards with grass cover,which had 39.57% lower affected fruit rate than in no grass orchards. Use of brown sugar in no grass orchards could significantly improvethe effects the new lures, resulting in 18.45% reduction of affected fi＇uit.
