| 摘 要： | 苹果黄色叶螨(EOTERANYCHUS SP.)是我省三州和其它苹果产区的一种重要害螨。本试验测定了四种不同温度下的有效积温和发育起点温,得到了苹果黄色叶螨各虫态及全世代的有效积温(K)和发育起点温常数(C)及理论预测式(N)。经结合雅安地区气象资料推算验证与实际发生代数(8—9)基本相等。

| Abstract: | The apple yellow mite Eotetranyghus sp. is one of the important pests of apple tree in three autonomous districts of Sichuan Province and spread widely over many other apple yielding areas. This experiment contains: estimating threshold for devement(C), effective thermal constant(K) and its theoretical mathematical formula(N) under four various temperature conditions. The results are consistent with the real generation numbers(8—9 genrations) developed in Yaan. |
