摘要
比较研究了不同产地硅藻土对主要储粮害虫(玉米象、谷蠹、锯谷盗、锈赤扁谷盗)的杀虫效果。结果表明,1号硅藻土(产于浙江省嵊州市)对玉米象、锈赤扁谷盗、谷蠹、锯谷盗均有显著的毒杀效果,处理后5 d,杀虫效果可达100%,与对照硅藻土(普粮泰)无明显差异;2号硅藻土(产于吉林省长白县)除对玉米象无明显毒杀作用外,对其它三种害虫的杀虫效果在96%左右。实验说明不同产地的硅藻土对储粮害虫的杀虫效果有明显差异。
Insecticidal effects of diatomaceous earth from different places on major stored grain insects （Sitophius zeamais, Rhizopertha dominica, Oryzaephilus surinamensis, Cryptolestes ferrugineus ） were evaluated. The results showed that diatomaceous earth from Shengzhou in Zhejiang Province （trade name： Puliangtai） had significant toxicity to four insects mentioned above, its control efficiency was 100% on the 5th day after treatment. Diatomaceous earth from Changbai in Jilin Province, had significant toxicity to other three insects except S. zeamais, and its efficiency was about 96%. It was concluded that insecticidal effects of diatomaceous earth from different places on stored grain insects were different obviously.
