苹果红蜘蛛在北方果区发生普遍,危害日益严重,已成为果树生产上的重要害虫之一。由于其发生代数多、繁殖力强、发育速度快,长期使用单一药剂易产生抗药性,而且红蜘蛛还对不同药剂产生了不同程度的交互抗性,更增加了药剂防治难度。为寻求防治苹果红蜘蛛的高效药剂,我们在西安市长安区进行了10.5%阿维菌素·哒螨灵乳油防治苹果红蜘蛛田间药效试验。
Apple red spiders occur in the northern fruit area common, increasingly serious harm, has become one of the important pests in the production of fruit trees. Because of its occurrence of many generations, strong fertility, rapid development, long-term use of a single drug easy to produce resistance, but also for different spider mites have different degrees of interactive resistance, but also increased the difficulty of drug control. In order to seek effective pesticides to control apple red spider, we conducted a field efficacy trial of 10.5% abamectin-pyridaben in the prevention and cure of apple red spider in Chang’an District, Xi’an.
