| 摘 要： | １５℃和－２０℃的低温对山楂叶螨和李始叶螨的致死率分别为９４．７％、９６．０％和６９．３％、７４．７％，有极显著差异（Ｐ＜０．０１）；而－２５℃和－３０℃的低温对两种螨和同一种螨的致死率无显著性差异；高温对两种螨的影响也无显著性差异

| Abstract: | The lethal rates of Tetrangchus viennensis and Eogeprangchus Cruri at 15℃, and 20℃were 94.7 % and 96.0 %, respectively. The differences showed remarkable significant ( P <0.01). However, the lethal rates of two mites at -25℃ and -30℃didn't exist significantly difference. So did with the high temperatures (30℃, 35℃, and 40℃). |
