吹棉蚧,增殖快,大量吸取树液,并诱发烟煤病,影响光合作用进行。在虫口密度较大时,树势衰弱,叶落枝枯,产量下降,受害严重时,常致全株枯死。吹棉蚧虫体有蜡质保护,虫卵包藏在雌成虫尾部的棉状卵囊里,因而对药物有较强的抵抗力,用一般药物防治效果不够理想。用松脂合剂防治效果虽好,但配制施用技术烦杂,易生药害。江西南丰蜜柑园艺场和南丰县柑桔试验站职工,去年5月中旬用合成洗衣粉100倍液喷布试验,5天后即见雌虫卵囊硬化变脆,幼虫全身变白而死。喷液前蚂蚁成群上下,喷液后即不再见
Blow cotton scale, rapid proliferation, a large number of draw sap, and induced bituminous coal disease, affecting photosynthesis. Insect population density, the tree weak, leaves fall dead, yield decline, severe damage, often cause the whole plant died. Cotton wool insects have wax protection, insect eggs hidden in the tail of the female adult cotton-like oocysts, so the drug has a strong resistance, with general drug control effect is not ideal. Rosin mixture with the prevention and treatment effect is good, but the preparation of complex application of complex technology, prone to injury. Jiangxi Nanfeng citrus horticultural field and staff of Nanfeng County citrus test station, in mid-May last year with synthetic detergent 100 times liquid spray test, 5 days after the female oocysts sclerosis hardened, larvae white and died. Ants before spraying fluid up and down, no longer see after the spray
