抗性的历史节肢动物对农药抗性的历史,通常从1908年梨圆蚧(Quadraspidiotus perniciosus)对石灰-硫磺的抗性观察算起,尽管在这之前,在文献上已经有过下列的报道:关于苹果蠹蛾(Laspeyresia pomonella)防治上的错误教训,在经一、二年后,变得更明显了。在内布拉斯加州实验站附近以及种植者之间,尽管按照通常的施用方法进行防治,却造成很多困难。大幼虫不取食但轻易地蛀入苹果内,把苹果咬碎后排出来,小幼虫可能也是如此,这就为防治造成较大的困难。在加利福尼亚州能很容易杀死梨圆蚧的各种洗涤剂,在大西洋沿岸各州却变得出奇地无效。就是这些东部的梨圆蚧,在若干方面正在改变着它们自己的生活史和生活习性。
The history of resistant arthropods to pesticides has historically been characterized by lime-sulfur resistance observed in 1908 by Quadraspidiotus perniciosus, although prior literature has reported the following: Lessons learned about the prevention and treatment of Laspeyresia pomonella became more pronounced in one or two years. Near Nebraska’s experimental station and between growers, despite the usual methods of application, there are many difficulties. Large larvae do not eat but easily moth into the apples, the apple crushed after the discharge, small larvae may be the case, which makes the prevention of greater difficulties. The various detergents in California that can easily kill pest, have become surprisingly ineffective in the states of the Atlantic. It is these eastern pear scales, which in some ways are changing their own life history and habits.
