在28℃以下,桃蚜的发育历期随温度的升高而缩短;当温度达到30℃时,其发育历期延长。在25℃恒温条件下。成虫寿命平均为 7.38d,单雌产若蚜数平均为 38.29头;在日平均温度为21.29℃的自然变温条件下。成虫寿命平均为11.95 d,单雌产若蚜数平均为52.05头。若虫的发育起点温度为7.96℃,有效积温为81.48日℃。药剂防治结果表明,5%蚜虱净乳油2 000倍液、 0.6%虫螨光乳油 1000倍液和 2 000倍液、 20%绿保素乳油 1000倍液的防治效果最好,施药后3d的校正死亡率都在90%以上;40%乐果乳油1500倍液和50%抗蚜威可湿性粉剂2000倍液的防治效果较差、施药后3d的校正死亡率只有65%左右。
At 28 ℃, the developmental duration of Myzus persicae decreased with the increase of temperature. When the temperature reached 30 ℃, the developmental duration of Myzus persicae was prolonged. At 25 ℃ constant temperature conditions. The average life span of adults was 7.38 days, and the average number of aphids was 38.29. The average daily temperature was 21.29 ℃. The average life expectancy of adults was 11.95 days, and the average number of aphids per head was 52.05. Nymph development starting temperature of 7.96 ℃, the effective accumulated temperature of 81.48 ℃. The results showed that the control effect of the 5% imidacloprid EC 2000 times, 0.6% mite mite EC 1000 times and 2000 times, 20% After 3 days, the corrected mortalities were above 90%. The control effect of 40% dimethoate 1500 times and 50% pirimicarb WP 2000 was poor. The corrected mortality rate after 3d was only 65% .
