| 摘 要： | 通过对甘肃省陇南山区1992~2005年小麦红蜘蛛发生情况和气象资料对比分析得出:危害陇南山区麦类的红蜘蛛主要有麦圆红蜘蛛和麦长腿红蜘蛛,其危害期由南向北主要发生在2~4月,每年发生面积约66 666.7 hm2,造成小麦减产10%左右。小麦红蜘蛛发生程度与上年9月至当年3月的逐月气温呈正相关,与该时段降水量呈显著的反相关;而与4~8月的逐月气温呈负相关,与该时段降水量呈正相关。

| Abstract: | By using wheat red mites data and meteorological data in Longnan mountainous area of Gansu Province from 1992 to 2005,the wheat red mites appearing circs are investigated and analyzed.The main results are as follows: There are two main kinds of wheat red mites there,namely Penthaleus major(duges) and Petrobia latens(mullen),which appeared mainly from February to April each year.Because of wheat red mite's harm,wheat yield is reduced about 10% in the area of 66 670 hm2 each year.There is a positive correlation between the wheat red mite probability and monthly mean temperature from September to March,but for precipitation during that period it presented remarkable negative correlation,with respect to the period from April to August,there is a negative correlation for monthly mean temperature but positive correlation for precipitation.Finally the prediction model of wheat red mites appearing in Longnan mountainous area is established in terms of agricultural meteorology,and the probability of accuracy is 100% in 2006 and 2007's operation predictions. |
