近年来,我区从河南、山东、河北和山西等省引进不少红枣苗,现枣树已大量结实。但由于检疫不严,梨园蚧随引种苗木传了进来,并在阿克苏、莎车、库尔勒、伊犁等地滋生蔓延,危害日趋严重。据1981年在温宿扎木台试验站调查,结实枣树中有蚧株率达56.7％,严重受害株占32.4％。由于梨园蚧长期附在枣树的枝、梢、果实上刺吸汁液,致使枝梢干枯、树势衰弱,结实量大减(减少3/4—4/5),严重受害树枣实无食用价值的占44—62％,能勉强食用的风味也欠佳。1981—1982年,我们在扎木台试验站定株对梨园蚧进行了化学防治、生物防治及人工刮治试验,结果如下:
In recent years, my district from Henan, Shandong, Hebei and Shanxi Province introduced a lot of jujube seedlings, Jujube is now a large number of strong. However, due to the lack of inspection and quarantine, Pear Scale came with seedlings introduced and spread in Aksu, Shache, Korla and Ili areas, causing more serious damage. According to a survey conducted in Wusuzuo Station in 1981, there were 56.7% strains of jujube in jujube trees and 32.4% of severely damaged strains. Pear long-term attached to the jujube pear branches, shoots, fruit sucking sucking juice, resulting in dry branches, shrubs weak, substantial reduction (reduced 3 / 4-4 / 5), seriously harmed tree jujube without food The value of 44-62%, can barely eat the flavor is also poor. In 1981-1982, we carried out chemical control, biological control and manual scraping test on pear scale in Kuzamta test station. The results are as follows:
