摘要
【目的】为掌握平和琯溪蜜柚锈壁虱发生规律,了解其消长因素,总结研究防控对策,以科学指导综合防治工作。【方法】采取定点观察法、巡回踏查法、抽样法对琯溪蜜柚锈壁虱发生世代、发生盛期、生活习性等进行调查、观察。【结果】锈壁虱在平和县一年发生20~24代,世代重叠,繁殖力特别强。生活周期短,平均一代历期10~19 d。成螨、若螨在当年生夏、秋梢的腋芽内,以及病虫等因素引起的卷叶内越冬。翌年3月,当气温上升到15℃左右时,越冬成螨开始活动。4月迁移至果实危害。温度23~32℃,相对湿度70%~80%最适宜。4—10月发生盛期。【意义】研究将为平和县及其周边地区蜜柚锈壁虱的有效防控提供技术帮助。
[Purpose]In order to master the occurrence law of Guanxi honey pomelo rusting ticks,to understand its growth and decline factors,to summarize the research control countermeasures,to guide the Comprehensive Control Work Scientifically.[Method]The generation,flourishing period and living habits of Guanxi Honey Pomelo were investigated and observed by fixed-point observation,roving and sampling.[Result]The rust mite occurs in 20-24 generations a year in Pinghe County,with overlapping generations and high fecundity.Short Life Cycle,average generation duration 10-19 days.The adults and NYMPHS overwinter in the axillary buds of the summer and autumn shoots of the same year,and in the rolled leaves caused by diseases and insects.In March of the following year,when the temperature rose to about 15℃,the overwintering adult mites began to move.April migration to fruit hazards.The optimum temperature is about 23-32℃and the relative humidity is between 70%-80%.April-october peak.[Significance]The study will provide technical assistance for the effective control of rust mite grandis var.citrinopileatus in Pinghe County and its surrounding areas.
