| 1 | The Prevention and Elimination of Insects in Storage of wheat Grains by Gamma Irradiation显示文摘This article deals with radiation sensitivity and lethal dose on the main cereal insects such as:Oryzaephilus Surinamensis Linnaeus(OSL),Sitophilus Oryzae Linnaeus(SOL),Rhizopertha Dominica Fabricius(RDF)and Tribolium Castaneum Herbst(TCH)in China.The experiments showed that there was a difference in radiation sensitivity.Among four insects species,OSL had the least tolerance;the second was RDF;the next was SOL and TCH had the biggest tolerance.After radiation with 0,15KGY-0.3KGY all OSL were dead in 2 weeks,all SOL and RDF dead in 3 weeks and all TCH dead in 4 weeks.All eggs could not be incubated with 0.1KGY radiation dose and adults insects had no bearing ability with 0.1 KGY radiation.There was no negative effect on germination potential and germination percentage of wheat with less than 1.0 KGY radiation.The article deals with bioeffect and lethal dose on OSL,SOL,RDF and TCH by ^60Co gamma ray radiation and with wheat germination potential and germination percentage.The economical and reasonable conditions are found for the development of science and technology and to provide the basis for the commercial operation. | AllaouaAchouri LiJizhang 等 | 2000 | 中国粮油学报2000，15，C00： | 0 |
