玉米三点斑叶蝉发生及防治的研究

Study on the Occurrence and Control of Corn Threespotted Leafhopper

玉米三点斑叶蝉ＺｙｇｉｎａｓａｌｉｎａＭｉｔ．是新疆近几年严重发生的一种玉米害虫．在新疆一年发生３代，成虫在冬麦田及田边、渠边、果园、林带的禾本科杂草上越冬．翌年４月出蜇危害小麦、玉米．在玉米嗽叭口期投放３％呋喃丹颗粒剂．每公顷２２．５ｋｇ，或２０％火扫利乳油１５００倍液喷雾可控制危害．

A destructive insect, Corn Threeespotted leafhopper Erythroneuraspisne is newly occurred in nothern regions of Xinjiang. The pest develops three generations annually,survies the winter in the adult chiefly on winter wheat and other grass weeds. When warm,spring weather arrives, the adults firstly damage winter wheat and spring wheat, migrate corn in May or Jane, and then back again to winter wheat in fall.It is the most efficient to apply 3 percent Carbofuran granules control at the rate of 22.5 kg/hm2 on the whorl stage corn. In the meantime, it can control first-generation corn bores.
