摘要
为了研究新疆玛纳斯河流域棉蚜的抗药性现状,利用吡虫啉、吡蚜酮、阿维菌素、高效氯氰菊酯和高效氯氟氰菊酯5种杀虫剂对新疆玛纳斯河流域的122团、143团、145团、147团、新湖农场等5个试验点的棉蚜(Aphis gossypii Glover)种群采用FAO推荐的浸渍法进行了抗性测定,并与敏感棉蚜的测定结果进行比较。结果表明,玛纳斯河流域棉蚜种群对高效氯氰菊酯的抗性倍数为4.54～9.04,对高效氯氟氰菊酯抗性倍数为8.56～9.07,对吡虫啉的抗性倍数为2.32～3.6,对吡蚜酮的抗性倍数为1.37～1.57、对阿维菌素的抗性倍数为1.12～1.31,表明利用菊酯类农药防治棉蚜可能加快棉蚜产生抗药性。
To study the resistance status of aphid from the Manas River,the resistance of Aphis gossypii collected from five locations of Manas River Basin,including 122 farm,143 farm,145 farm,147 farm,Xinhu farm to imidacloprid,pymetrozine,abamectin,beta-cypermethrin,lambda-cyhalothrin were determined for the dipping method recommended by FAO.The results indicated that the resistance of aphid populations from the Manas River basin to beta-cypermethrin was 4.54-9.04 fold,to lambda-cyhalothrin was 8.56-9.07 fold,the imidacloprid was 2.32-3.6 fold,the pymetrozine was 1.37-1.57 fold,to abamectin was 1.12-1.31.The use of pyrethroid pesticides to control aphid may accelerate the development of resistance.
