摘要
为掌握杏芽瘿在新疆哈密市对杏树的危害,于2020—2022年对哈密市杏芽瘿的害螨种类、发生规律和发生分布情况进行了调查。结果表明,造成杏芽瘿的致害生物为梅下毛瘿螨Acalitus phloeocoptes (Nalepa),该螨主要以成螨在活杏芽内越冬,3月下旬至9月持续为害杏树,4—6月为其危害高峰。2022年杏芽瘿在哈密市伊州区的18个乡镇(街道)的杏树上均有不同程度的发生,2021年平均瘿瘤株率为68.64%,螨害指数为21.75,发生最重的天山乡瘿瘤株率高达90%,螨害指数为31.65。针对近几年该螨害进一步扩散蔓延的趋势,提出应通过加强杏树栽培管理,结合药剂防治的方法进行及时防治。
To understand the damage of apricot bud gall in Hami,the species,occurrence dynamics,and distribution of harmful mites in apricot bud gall were investigated and analyzed from^(2)020 to 2022.The results showed that Acalitus phloeocoptes(Nalepa)was the pathogenic organism that caused apricot bud gall in Hami.The mite mainly overwintered in living apricot buds as adult mites and continued to damage apricot trees from late March to September.The damage peak was from April to June.According to the investigation,apricot bud galls occurred in 18 towns(streets)of Yizhou District in 2022.In 2021,68.64%of the apricot trees surveyed were found to have bud gall,with an average mite damage index of 21.75.Tianshan township was the most severely damaged area with a diseased plant rate of 90%and a mite damage index of 31.65.Given the trend of further spread of mite damage in recent years,it is suggested that the management should be strengthened and combined with the method of chemical control for timely prevention and control.
