防治大蜂螨的关键,在于药剂的有效使用方法比对大蜂螨的毒性更重要。1)便于使用;2)对污染蜂蜜的程度要小;3)在蜂群内药剂能广泛接触到大蜂螨。这些都是在药剂防除大蜂螨时所需要遵循的原则。我们在本次试验中注意了以上三点。材料和方法室内试验在做药效处理之前,将从蜂群中收集成蜂身上的大蜂螨。试验用药是马拉硫磷原液(99％),其中水解产物甲醇可忽略不计。用适量蒸馏水稀释,经浸泡法和
The key to the prevention and control of bee mites lies in that the effective use of medicaments is more important than the toxicity to beetles. 1) Easy to use; 2) To a lesser degree of contamination of honey; 3) In large swarms, large doses of bee mites can be exposed to chemicals in bees. These are the principles to be followed when using pesticides to control aphids. We note the above three points in this experiment. MATERIALS AND METHODS In-house trials were collected from bee colonies to bee mites prior to pharmacodynamics. The test medication was a malathion solution (99%) with negligible methanol hydrolysates. Diluted with an appropriate amount of distilled water, by soaking and
