我国自60年代应用磷化氢熏蒸储粮害虫以来,已发现部分害虫产生了抗性。为了提高杀虫效果,我们曾于1977～1979年采用气调条件下低浓度磷化氢熏蒸杀虫效果的研究。前两年主要在郊县粮库进行籼谷杀虫效果的试验,后一年主要在市区粮库开展籼米杀虫效果的研究。气调条件下低浓度磷化氢熏蒸杀虫法,是指把
Since the application of phosphine in China in the 60s to fumigate stored grain pests, some pests have been found to be resistant. In order to improve the insecticidal effect, we used 1977 ~ 1979 under the atmosphere conditions of low concentration of phosphine fumigation insecticidal effect of the study. The first two years mainly in the counties grain banks to test the insecticidal effect of indica rice, the year after mainly in the urban grain storage indica rice insecticidal effect. Atmospheric conditions of low concentrations of phosphine fumigation Insecticidal law, refers to the
