苹果小吉丁虫（ＡｇｒｉｌｕｓｍａｌｉＭａｔｓｕｍｕｒａ）属鞘翅目，吉丁虫科。其幼虫可在果树皮下蛀食，导致果树减产、绝收和死亡。该虫一直是我省检疫对象，８０年代初，只有民和、循化两县的６个乡（镇）偶有发生。今年，全省各苹果产区大面积普遍发生，且为害严重... Apple small jilin bug (AgrilusmaliMatsumura) is Coleoptera, Jibinidae. Its larvae can be eaten under the fruit tree skin, resulting in reduced fruit yield, yield and death. The insect has always been the object of quarantine in our province. In the early 1980s, only 6 towns (towns) of Minhe and Xunhua counties occasionally occurred. This year, the apple-growing areas across the province have been widespread and severely damaged.
