黄板诱杀及与烟剂配合应用防治南美斑潜蝇试验研究

Control Effect on Fly Liriomyza huidobrenisis Utilizing Yellow Plastic Boards and Combining the Boards with Smoke Agent

采用黄板诱杀及黄板诱杀与烟剂配合使用防治南美斑潜蝇的试验结果表明,番茄和茄子大棚悬挂黄板600~750张/hm2对南美斑潜蝇的防效:番茄的虫株率防效、虫口防效和叶面积防效分别达82.06%、89.67%和91.17%以上;茄子的防效分别为79.61%、83.82%和87.62%以上。悬挂黄板675张/hm2并配合应用10%烟熏死烟剂7500g/hm2对番茄、茄子大棚南美斑潜蝇的虫口防效分别为97.04%、95.76%。

Field trials for controlling the fly Liriomyza huidobrenisis Blanchard by utilizing yellow plastic boards withthe scale of 600～750 sheets/hm^2 were done in tomato and eggplant greenhouse.The results showed that the control effect of investing plant ratio, that of pest population and that of leaf area reached 82.06%, 89.67% as well as 91.17% in tomato greenhouse, and 79.61%, 83.82% as well as 87.62% in eggplant greenhouse, respectively. The control effects on the fly reached 97.04% and 95.76% respectively when the dosage of 7 500 g/hm^2 10% Yanxunsi smoke agent was combined to apply with hanging yellow plastic boards 675 sheets/hm^2 in greenhouse.
