柑橘木虱是柑橘黄龙病的唯一自然传播媒介,因此大面积范围内严格防除柑橘木虱是防治黄龙病最重要的措施。当前柑橘进入秋梢抽梢期,柑橘木虱卵、若虫的发生盛期与柑橘抽梢期相适应。根据近期植保部门对广西部分柑橘园木虱监测的情况发现,各果园柑橘木虱发生差异较大,木虱发生面广,一些失管或管理不当的橘园木虱虫量仍较高。管理正常的果园一般有成虫0.1~0.2头/百梢,若虫0.5~0.8头/百 Citrus psylla is the only natural transmission medium for citrus Huanglongbing. Therefore, strict control of citrus psylla over a large area is the most important measure to prevent and cure Huanglonglong. The current citrus into the autumn shoots shoots, citrus psylla eggs, nymphs occurrence peak and citrus shoots phase adaptation. According to recent plant protection departments of citrus orchards in Guangxi monitoring of psyllids found that the citrus psyllid in different orchards occurred in large differences, a wide range of occurrence of psylla, some tube failure or mismanagement of Orangery lice population is still high. Normally managed orchards generally have adult 0.1 ~ 0.2 / 100, nymphs 0.5 ~ 0.8 / 100
