柑橘大实蝇诱杀方法研究及防治效果初步评估

Study on bait trapping methods for controlling Bactrocera minax and preliminary evaluation on their controlling effects

通过对柑橘大实蝇诱捕器悬挂高度及悬挂方位的效果比较,结果表明,诱捕器在树冠中层悬挂最为合适,与悬挂高度无关;诱捕器在阴面或者平地北面效果最好,阳面最差。诱杀柑橘大实蝇的合适配方为5%橙汁+5%水解蛋白+5%酒或5%红糖液+5%橙汁+5%水解蛋白。在柑橘大实蝇不同防治方法中,结合防治效果、成本及生态影响评估结果表明,诱杀方法最为合适。

Field experiments were conducted on evaluating the effects of different baiting methods for controlling Bactrocera minax. Results indicated that the height of baiting devices had no correlation with their effects, the locality of devices had significant correlation with their effects. The proper locality of baiting device was in the middle of tree canopy. Trapping effects were better when the device was put on shadowy side or the north of fiat land than on the sunny side. The proper prescription of bait was 5% orange juice ＋ 5% hydrolyzed protein ＋ 5% alcohol or 5% brown sugar solution ＋ 5% orange juice ＋ 5% hydrolyzed protein. Taking into account of effects, costs and ecological impacts, baiting was the best methods in controlling Bactrocera minax.
