我们知道一切动物,植物,甚至于人的许多生理活动,在一昼夜间是有节律的、周期性地变化着的。例如:很多植物的叶子在白天伸展,夜间闭合,人的体温有24小时的周期升降等等。我们联系到生物的昼夜间生理变化周期,探索一下茶树害虫在昼夜间对农药的敏感性和抗性的变化,可以为适时施农药提供依据。为此,我们用茶尺蠖(我场主要的,且已产生抗药性的茶叶害虫)作了试验。农药采用我场常用农药80%敌敌畏试验分二次进行,一次是第一代一龄幼虫;另
We know that many of the physical activities of all animals, plants, and even humans are rhythmic and cyclical throughout the day and night. For example: a lot of plant leaves in the daytime stretching, closed at night, the body temperature of 24-hour cycle movements and so on. We relate to the biophysical cycle of diurnal physiology, and explore the changes of sensitivity and resistance of tea tree pests to pesticides during the day and night, which can provide the basis for timely application of pesticides. For this reason, we tested with tea scallops (my main, pest-resistant tea plant pests). Pesticides using my field commonly used pesticides 80% dichlorvos test sub-two times, once the first-generation first-instar larvae; the other
