八种杀虫剂对大豆田蚜虫室内杀伤力和对天敌毒性测定

TESTS OF EIGHT INSECTICIDES EFFECT ON THREE BEAN APHIDS AND THEIR TOXICITY TO NATURAL ENEMIES OF APHIDS

蚜虫既是大豆的主要害虫之一,又是大豆病毒病的重要传播介体。每年因蚜虫的直接为害和其传播大豆花叶病毒所造成的损失十分严重。因此,测定有关杀虫剂对蚜虫的防治及其对天敌的毒性,合理用药,保护天敌,达到既控制蚜害又减轻大豆花叶病毒(SMV)流行,具有重要的实践意义。笔者测定了八种杀虫剂对危害大豆的三种蚜虫的杀伤效果和对二类天敌的毒性,从中选择出了适宜的药剂。
