金川雪梨名闻全国,国际市场亦有崇高声誉。但自1973年遭黄粉蚜Aphanostigmajakusuiense(Kishida)毁灭性为害后,梨果严重减产,品质变坏不耐贮藏,外贸被迫停止,内销不受欢迎,迫切需要防治。 梨黄粉蚜的资料极少,仅1929年日本田边中一对其形态学有过较详研究,生物学、生态学及防治等都有不少问题。 1974、1975和1978年,我所对黄粉蚜生物学作了观察,报道于后供参考。
Jinchuan Sydney famous throughout the country, the international market also has a high reputation. However, since the devastating damage caused by Aphanostigmajakusuiense (Kishida) in 1973 by the yellow aphid Aphanostigmajakusuiense (Kishida), the pears have been seriously reduced in yield and their quality has become impatient for storage. Foreign trade has been stopped and the domestic market is unpopular. There is an urgent need for prevention and treatment. Pear yellow powdery aphid very few information, only in Japan in 1929 Tanabe had a more detailed study of its morphology, biology, ecology and prevention and so have many problems. 1974, 1975 and 1978, I observed the biology of yellow aphid, reported for reference.
