梨蝽象是我国北方梨树上的主要害虫之一,在国內分布于辽宁、河北、山东、山西等省,本省以辽西最重,主要为害梨树、梨果。受害的梨树,新梢发育不良,果实畸形,严重时整棵梨树枯死。此虫在过去很少有人研究与报导,果农又缺少好的防治方法。我們于1953年曾进行过它的生活史习性观察与药剂防治試驗,簡述于后。 Pear like as one of the main pests on the northern pear tree in China, located in Liaoning, Hebei, Shandong, Shanxi and other provinces, the province to Liaoxi the heaviest, the main damage pear, pear fruit.
