1974—76年观察,日平均温度在13.18—24.89℃时茶半跗线螨一年发生20代。日平均温度在10.7—33.9℃时一年发生30代。发育历期:卵1—8天;幼螨1—10天,雌成螨产卵前期1—6天;全世代3—4天。其发育阶段,经过卵、幼螨、成螨三个阶段。每雌螨产卵平均40粒以上,雌成螨寿命20天以上。日平均温度在22.7—24.43℃时发生最盛。当日平均温度下降到10℃以下,雌成螨即于茶芽鳞片叶柄缝穴处越冬。翌年日平均温度上升至10℃以上
1974-1966 observed that the average daily temperature at 13.18-24.89 ℃ when the tea halophyte mites occur 20 generations a year. The average daily temperature at 10.7-33.9 ℃ occur 30 times a year. Developmental period: eggs 1-8 days; larvae 1-10 days, female adult mites oviposition 1-6 days; all generations 3-4 days. Its developmental stage, after eggs, larvae, mites into three stages. An average of 40 eggs per female mite spawning, female adult mites live more than 20 days. Daily average temperature occurs at 22.7-24.43 ℃ when the peak. On the day the average temperature dropped below 10 ℃, female adult mites in the tea bud petiole seams point overwintering. The following year the average daily temperature rose to above 10 ℃
