茶橙瘿螨是我国茶树的主要害虫之一。本文旨在公布浙江余杭、浙江农大茶园5年中关于其种群消长、丛内分布以及田间分布型方面的调查结果。五天一次的调查表明:5、6月间为发生盛期,形成全年第一个,也是最显著的高峰;其后因气候不同可有0至3个次高峰或小高峰。因而,主要对夏茶生产构成严重威胁,其次是秋茶。气温以平均18～25℃左右最为适宜,长期在27℃以上对其不利,将影响7、8月间第二个高峰的出现,甚至影响整个下半年的螨口。一般,大雨尤其是暴风雨明显降低螨口数量。雨量小、雨日多,时晴时雨,则有利其发生。具暴发性,条件适宜时螨口可在10天之内增长数
Tea orange scabies mites is one of the main pests of our country tea tree. The purpose of this paper is to publish the results of surveys on the population growth and distribution and field distribution in Yuhang, Zhejiang Province, Zhejiang Province. The five-day survey shows that May and June are peak periods and the first and most significant peak of the year, followed by 0 to 3 sub-peaks or small peaks due to different climates. Thus, the main threat to summer tea production poses a serious threat, followed by autumn tea. The average temperature of 18 ~ 25 ℃ is the most appropriate, long-term at 27 ℃ above its adverse, will affect the second peak in July and August appeared, and even affect the second half of the mite mouth. In general, heavy rains, especially storms, significantly reduce the number of mites. Small rainfall, rainy days, sunny when the rain, it is conducive to its occurrence. With outbreaks, conditions suitable mite mouth can be increased within 10 days number
