摘　　要： 分别采用浸卵法、浸渍法和浸叶法测定了22、25、28、31和34℃下吡虫啉对B型烟粉虱Bemisia tabaci B-biotype不同虫态的控制效果。结果表明,随着温度的升高,吡虫啉对B型烟粉虱不同虫态的控制效果也逐渐上升,当温度上升至34℃时,60mg/L浓度药液处理下卵、低龄若虫、高龄若虫及成虫死亡率分别较22℃时升高了20.89%、33.52%、33.37%及17.86%。因此,温度提高对吡虫啉防治B型烟粉虱起到了正面效应。 The effects of imidacloprid on the different stages of Bemisia tabaci B - biotype at the temperatures of 22℃, 25℃, 28℃, 31℃ and 34℃ were detected using the dipping egg, impregnation and dipping leaf methods. The results showed that the control effects of imidacloprid on the different stages of B. tabaci gradually increased with the increasing of temperature, and the 60 mg/L imidacloprid treatment was the most evident. Besides, compared with the treatment of 22℃ and 34℃, the control effects of 60 mg/L imidacloprid on B. tabaci eggs, low - instar nymphs, high - instar nymphs and adults rose by 20. 89%, 33.52%, 33.37% and 17.86% respectively. Consequently, the increasing of temperature has positive effect on the control of B. tabaci by imidacloprid.
