摘要
凹缘菱纹叶蝉是枣疯病的一种重要媒介昆虫。在河北省石家庄市西部山区,该虫一年发生4代。从9月中旬到11月上旬,第4代成虫大多数直接从枣树飞往油松和侧柏上越冬。第2年4月中旬,越冬成虫从松、柏树飞往桑树和构树上繁殖1代。5月下旬到6月上旬,第1代成虫飞到枣树上繁殖3代。在田间用几种农药防治,灭扫利(Methrin)的效果最显著。
Hishimonus sellatus Uhler is one of the major vectors of jujube witche's broom disease. The author studied it's migration and control measures from 1986 to 1989. This pest has four generations per year in the west mountains of Shijiazhuang, Hebei Province., Most adults of the 4th generation migrate directly from jujube to pine (Pinus tabulaeformis Carr.) or orborvitae (Platycladus orientalis Franco) nearby from the middle of September to October every year to overwinter there. After winter, the surviving images begin to migrate to the white mulberry (Moras alba L.) and common papermlberry (Broussonetia papyrifera Vent) on about 20th April next year, and they reproduce one generation there. Then, they migrate to jujube and reproduce three generations from the end of May to the beginning of June. Experiments show that Meothrin is remarkbly effective for controlling this pest.
