| 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、谷蠢、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.

| Abstract: | 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 thr... |
