苌楚鸠蝠蛾ＰｈａｓｓｕｓａｃｔｉｎｉｄｉａｅＹａｎｇｅｔＷａｎｇ是福建近年来严重为害猕猴桃的一种新的蛀干害虫．我们于１９８４－１９８９年在建宁县猕猴桃试验站进行研究。该虫一年一代，以卵在树兜的地面越冬，幼虫为害猕猴桃植株韧皮部和髓部，外部形成虫屑包，内部形成蛀道，阻滞养分和水分的正常输送，轻者枝叶发黄，重者风折枯死。除选用抗虫品种外，采用２．５％溴氰菊脂１：５０００液灌注；９０％敌百虫晶体１：２００制成毒泥塞虫孔；凡士林加敌敌畏环涂阻止幼虫上树；细铁丝钩杀幼虫、捕捉刚羽化成虫等综合防治措施，效果良好。
PhassusactinidiaeYangetWang is a new stem borer that has been severely damaged by kiwifruit in Fujian in recent years. We conducted a study at the Kiwi Experimental Station of Jianning County from 1984 to 1989. The worm a year, with eggs in the tree pocket winter, the larvae damage kiwifruit plant phloem and pulp, the external formation of worm meal package, the internal formation of tunnels, blocking the normal transport of nutrients and moisture, light yellow leaves, Heavy wind died. In addition to the selection of insect-resistant varieties, the use of 2.5% deltamethrin 1: 5000 liquid perfusion; 90% trichlorfon crystal 1: 200 made of toxic sludge hole worm; Vaseline plus dichlorvos ring to prevent larvae on the tree; fine Wire hook to kill larvae, catching the emergence of adult insects and other integrated control measures, the effect is good.
