枣树丰产措施之一是枣树开花后于主干进行环剥。但在环剥后,常有昆虫在愈伤组织内潜蛀为害,影响枣树营养液的输导和伤口愈合,当年减产15～20％,如不及时防治,数年后可造成树体死亡。经过1990～1991年的观察研究,现已明确,这是中国枣树新害虫——皮暗斑螟(Europhera batanyensis Caradja)为害所致。该虫隶属于鳞翅目(Lepidoptera),螟蛾科(Pyralidae),斑螟亚科(Phycitinae)。 该种昆虫于1939年由Caradja定名,但其寄主一直不明。我们对该虫的研究,填补了为 One of the measures for jujube tree yielding is that the jujube is girdled on the trunk after flowering. However, after girdling, insect insects often infestation in the callus damage, affecting jujube nutrition fluid conduction and wound healing, then cut 15 to 20%, if not timely control, can cause tree death after a few years . After 1990-1991 observation and study, it has been clear that this is the Chinese jujube new insect pest - Cootfish (Europhera batanyensis Caradja) damage caused. The insects belong to the family Lepidoptera, Pyralidae, Phycitinae. The insect was named after Caradja in 1939, but its host remains unknown. Our research on this bug fills it up
