摘要
杨始叶螨Ｅｏｔｅｔｒａｎｙｃｈｕｓｐｏｐｕｌｉ（Ｋｏｃｈ）是危害杨、柳科植物的重要害螨。研究结果表明，该螨以受精雌成螨滞育，为长日照（１３ｈ／ｄ以上）发育，短日照（１１ｈ／ｄ）滞育型；临界光照时间为１２ｈ／ｄ左右；光周期感应螨态为幼螨→第一若螨→第二若螨的连续２个发育阶段。在相同短日照（１０ｈ／ｄ）下，较低温度（２１℃以下）促进滞育，较高温度（２５℃）抑制滞育。
The present paper deals with diapause of Eotetranychus populi (Koch).The results show that E.populi expresses diapause with fertile female adults,and it grows under long light (above 13 hours light per day) and produces diapause under short light (below 11 hours light per day). The threshold of photoperiod inducing diapause is at 12 hours light.The larva,protonymph are sensitive to photoperioodic changes,but the adults and eggs are not.Lower temperature (below 21℃) promotes the incidence of diapause and higher temprature (above 25℃) restrains it when they are subject under the photoperiod of 10 hours per day.
