山东济阳厉年蝼蛄为害很严重。采用六六六毒饵防治,在施药后的第二天早晨,发现地上有很多死蝼蛄,但效果却不很显著。经过济阳县农业技术推广站和农民仔细研究的结果,发现死蝼蛄在太阳下晒到上午10点左右,就开始复活,到中午12点完全恢复活动力,重新逃到地下。如施药后第二天阴雨,蝼蛄就不会再复活。因此,发动群众在施药后第二天早晨检去死蝼蛄。这样,杀虫效果就很显著。蝼蛄中毒后复活的情况说明了六六六的毒理作用。因为六六六通过昆虫的表皮、消化器官、气孔进入体内,温度愈高进入的速度愈快,昆虫中毒亦较快。但昆虫中毒后进入昏迷状态,并没有真死,而进行着生理解毒作用,温度愈高解毒作用就进行得愈快,也就是复活的机会愈高,杀虫率愈低。所以施药时温度较高使昆虫较易中毒,中毒后温度降低使昆虫不易从中毒状态中恢复过来,可以获得除虫的最大效果。
Shandong Jiyang Li 蝼 蛄 damage is very serious. Six hundred sixty-six poison bait prevention and treatment, in the morning after the application of the next day, found that there are many dead grubs, but the effect is not very significant. After Jiyang County Agricultural Technology Promotion Station and farmers carefully studied the results and found dead in the sun sundial drying around 10 o’clock in the morning, began to revive, to 12 o’clock fully restored activity, to escape to the ground again. If the next rainy day after application, the 蝼 蛄 will not be revived. Therefore, the masses were mobilized to die in the morning after the pesticide application. In this way, insecticidal effect is very significant. After the poisoning, the situation of resurrection shows the toxic effects of 666. Because BHC through the insect’s epidermis, digestive organs, stomata into the body, the higher the temperature into the faster, insect poisoning is also faster. However, insects into a coma after poisoning, and not real death, and conduct a detoxification, the higher the temperature detoxification carried out faster, that is, the higher the chance of resurrection, the lower the insecticidal rate. Therefore, when spraying high temperature so that insects more susceptible to poisoning, reducing the temperature after poisoning so insects not easy to recover from the poisoning state, you can get the maximum effect of pest control.
