近年来,吹绵蚧在我县部分柑桔产区有发展趋势。此虫增殖快,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。吹绵蚧虫体有蜡质保护,虫卵包藏在雌成虫尾部的绵状卵囊里,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。我场职工今年五月中旬喷布一次100倍的合成洗衣粉液,五天后检查,即见雌虫卵 In recent years, blowing cotton wool in my county part of the citrus growing areas have trends. The worm proliferated rapidly, 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. Pacomas lanceolata wax body protection, the eggs stored in the female adult worm-like oocysts in the tail, so the drug has a strong resistance, with the 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. I field workers sprayed in mid-May this year, a 100-fold synthetic detergent solution, five days after the inspection, that is, female eggs
