摘　　要：调查了不同施肥处理、水稻不同栽插期稻茎毛眼水蝇危害状况。结果表明,同一品种不同施肥处理稻茎毛眼水蝇危害株率差异不明显,水稻不同栽插期稻茎毛眼水蝇危害株率差异较大,随栽插期推迟危害株率明显增加。并优选出对稻茎毛眼水蝇具有一定抗性的81个水稻品种(系)。The circumstances of rice injured by hydrellia sasakii under different fertilizations, date of transplanting and varieties were investigated in 1994-1996. The results show that there are no significant difference in the number of injured plants by hydrellia sasakii on the same variety in various fertilizer treatments, while significant difference exists when the seedling transplanted at different dates. As date of transplanting is put off,the rate of injured plants increases significantly.81 varieties that have some resistance have been selected.
