对柑桔黑刺粉虱的生活习性、发生规律、有效积温、天敌种类和药剂防治等进行了比较系统的研究。该虫在广东一般1年发生5代,第1代成虫出现于3月份,11月中下旬以后若虫和蛹开始越冬;发育起点温度为11.01℃,完成1个世代所需有效积温为791.27日度。天敌主要有红点唇瓢虫、草蛉、蜘蛛、捕食螨以及刺粉虱黑蜂、黄色跳小蜂等。药剂试验表明,氧化乐果、水胺硫磷、速扑杀等药剂单用时效果不理想,但氧化乐果和水胺硫磷混配后效果有所提高,如果与机油乳剂配合使用,则效果更好,可达到90.93％,复配剂B[40％氧化乐果(0.32)+40％水胺硫磷(0.48)+4.5％高效氯氰菊酯(0.15)+增效剂(0.05)]的防效最好,达97.71％,是目前防治柑桔黑刺粉虱最好的药剂之一。
The life habit, regularity, effective accumulated temperature, natural enemies and control of citrus blackfly whitefly were systematically studied. The insects occurred in Guangdong for 1 year generally 5 generations, the first generation of adults appeared in March, nymphs and pupae in late November after the beginning of winter; developmental starting temperature of 11.01 ℃, completed a generation required effective accumulated temperature of 791.27 . Natural enemies mainly red-spotted ladybugs, scabies, spiders, predators mites and whiteflies black bees, yellow jumping bees and so on. Pharmacy tests showed that omethoate, isocarbophos, speed culling and other agents alone with less than ideal results, but omethoate and methamidophron mixed effect has improved, if used in combination with the oil emulsion, the effect Better, 90.93%, and B [40% omethoate (0.32) + 40% acetoside (0.48) + 4.5% beta-cypermethrin (0.15) + synergist (0.05)] Best, up to 97.71%, is one of the best agents to prevent and cure citrus whitefly.
