柑橘木虱诱捕器诱捕效果试验

Trial on trapping effect of the Diaphorina citri trappers

研究黄板信息素诱捕器不同悬挂高度与悬挂方位对柑橘木虱诱集效果的影响,结果表明:诱捕器悬挂在树冠中层(1.5 m)诱集的虫量最多,其次为树冠下层(0.8 m),树冠上层(2.0m)诱集效果最差;诱捕器悬挂在树冠北面诱集的虫量最多,其次为树冠西面和树冠南面,树冠东面诱集效果最差。

Effects of controlling pests of Diaphorina citri by the yellow plate pheromone trappers with different hanging heights and positions were comparatively studied. The results showed that the most amount of Diaphorina citri was trapped when trapper hanged at the middle of the canopy （ 1.5 m high）, followed by hanged at the lower of the canopy （0.8 m high）, and the worst effect at the upper of the canopy （2.0 m high）. Among different positions, the best trapping effect was achieved when hanged at the north of the canopy, then the west and south, and the worst effect at the east of the canopy.
