由于害虫抗药性问题的出现,使化学防治面临严峻的考验,目前急待解决以下问题:1、进一步考虑药剂使用过程中的安全操作。2、控制残留物污染。3、防止害虫抗药性产生。上述方面已经成为防治人员必须首先考虑的问题。我国储粮害虫防治工作,过去二十多年之所以卓有成效,其主要手段是采取化学防治。但是,由于抗药性、污染等问题出现。目前保粮人员开始寻求新的防治途径,例如:利用低温、缺氧储存,辐射杀虫、昆虫激素等等。这些方法无疑将为我国储粮害虫防治工作开辟日益广阔的途径。但是,
Due to the emergence of pest resistance problems, chemical prevention and control is facing a severe test. At present, the following problems are urgently needed to be solved: 1. Further consideration should be given to the safe operation during the use of pharmaceuticals. 2, control residue contamination. 3, to prevent pest resistance. The above aspects have become the first issues that prevention and control personnel must consider. The prevention and control of stored grain pests in our country over the past two decades have been fruitful. The main measure is to take chemical prevention and control. However, due to resistance, pollution and other issues arise. At present, food security personnel are beginning to seek new ways of prevention and control, for example: the use of low temperature, hypoxic storage, radiation insecticides, insect hormones and so on. These methods will undoubtedly open up an increasingly broad channel for pest control of stored grain in our country. but,
