They are potential sources ofstickies and their chemical nature; classification and deposits mechanism of stickies as well as harmfullness from stickies; methods forquantiative characterization and qualitative analysis of stickies; mechanical control methods for stickies; chemical methods for stickiescontrol; stickies control programme in paper mills and future trends in stickies research studies.展开更多
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...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。展开更多
