摘要
经1988-1991年研究表明,浙江桔区为害柑桔的蚜虫类有5种,棉蚜Aphis gossypii(Gloved已上升为主要的优势种群,占平均数的58.6％,这在我国还是新纪录。其次是桔蚜Toxoptera citricidus(Kirkaldy).和绣线菊蚜A.citricola(van der Goot)。近年,我国柑桔新梢有蚜率可达70％以上,并以混合种群的形式发生;春夏是主要为害期,其次是夏秋季。一般春梢比秋梢重,幼龄树、肥水条件好和靠近村落的桔园受害较重。好年冬(Marshal)、万灵(Lannate)、叶蝉散(Isoprocarb)等对该类害虫有较好的防治效果。
Five species of aphids were found through the survey of aphids attacking citrus plants in Zhejiangin 1988-1991. The succession of the predominant citrus aphids were observed and Aphis gossypii Glover has become the predominant species, which took 58. 6% of average in Zhejiang citrus orchards, and created an new record in China. Toxoptera citricidus (Kirkaldy) and A. citricola van der Coot occured secondly. The attacking of citrus aphids was very endangering in recent years. More than 70% new citrus shoots were damaged by the aphies, and several species of aphid were damaged by the same time. Their feeding that harmed the new shoots in spring was much more serious than that in autumn. This phenomenon differs from that in other provinces in South China. Usually the young trees, well-cultivated trees and the trees near villages were more seriously damaged by the aphids. Pesticides, such as, Marshal, Lannate and Isoprocarb have been selected for the controlling citrus aphids.
