1发生规律与特点 适温干旱是螨类猖獗发生的重要因素,气温12℃左右时螨类虫口开始增长;16℃时成倍增长,20℃以上盛发,28℃以上时会受到抑制;相对湿度60%~70%最宜,暴雨对螨类有较大的冲刷作用。螨类世代历期短,在发生盛期,完成一个世代需14 ~16天?
1 occurring laws and characteristics of moderate temperature and drought is an important factor mite rampant occurs when the temperature around 12 mites mite population began to grow; doubled at 16 ℃, more than 20 ℃ Sheng, more than 28 ℃ will be inhibited; Relative Humidity 60% ~ 70% optimum, heavy rain on the mites have a larger scouring effect. Mite generations of short duration, in the peak period, the completion of a generation to be 14 to 16 days?
