桔全爪螨是四川柑桔上的重要害虫,每年3月上旬开始为害,3—4月为害严重,春秋季出现几次螨口高峰。越冬基数大,春季3、4月份温度较高(周平均最高温25℃),适宜的日照和相对湿度。天敌较少,以及正值桔树发芽抽梢期等是形成春季第一次螨口高峰的主要条件。测报时应分析这几种生态因素的综合影响,使桔全爪螨在螨口高峰形成之前及时得到控制。
Citrus red mite is an important pest on Sichuan citrus, beginning damage in early March each year, March-April serious damage, several times in spring and autumn mite mouth peak. The overwintering base is large, and the spring temperatures are higher in March and April (the highest average temperature is 25 ℃ in the week), suitable sunshine and relative humidity. Less natural enemies, and the positive value of orange budding shoots are the first time in spring mite mouth peak of the main conditions. The report should be analyzed when the combined effects of these several ecological factors, so that the full-mite mite mouth peak time before the timely control.
