摘　　要：竹卵圆蝽天敌有7种,以卵期黑卵蜂寄生为主。竹卵圆蝽卵的寄生率,7月上旬为5％,以后逐渐增高,8月上旬高达76％以上。竹卵圆蝽的防治,可用药液喷雾或用50％甲胺磷竹杆基部打孔注射(每竹1.5—2.0ml),效果达90％;用黄油加机油1∶1,加1％农药于毛竹基部涂油环15cm,效果90％以上。Hippota dorsalis has seven natural enemies, most of which are preying ones. In its egg stage there are two species belonging to Telenomus spp. with rather high parasitic rate. The mean parasitic rate of early layed eggs is 5.17%, but after one month natural propagation, it can raise to 76.50%.The control methods are as follows:a. To spray 10 000-time liquid of Decis emulsion with a concentration of 2.5%, or 1 500-time liquid of Phenthoate with a concentration of 50%, the mortality of nymph will be over 93%.b. To inject 1.5-2.0ml of Methamidophos with a concentration of 50% into the base of bamboo culms, the mortality can be 90%.c. To spread a 15 cm ring on the base of bamboo culm with mixed oil composed by calcic lubricating oil, engine oil, and pesticide, the proportion of mixture should be 1:1:0.01,for preventing nymph to climb up to the bamboo culm and get food so that it will be dead of starvation, and the effect can be 90%.
