中文摘要：
采用室内和网罩试验,对7个不同品系赤眼蜂寄生玉米螟的卵块寄生率、卵粒寄生率及单雌产卵粒数进行比较。结果表明：不同品系赤眼蜂寄生玉米螟的效果不同,在同一基质玉米螟卵块上寄生效果存在显著差异（p〈0.05）;而同一品系赤眼蜂在不同基质玉米螟卵块上寄生也不同,蜡纸玉米螟卵块和鲜玉米叶子玉米螟卵块相比,多数赤眼蜂更趋向在鲜玉米叶子卵块上产卵;网罩下赤眼蜂寄生玉米苗上的玉米螟卵块效果更好,卵粒寄生率可达39.45%-70.48%;筛选出寄生玉米螟效果好的品系为：S-AC品系和M-TC品系,可应用于二代玉米螟的防治。
英文摘要：
Parasitism of seven Trichogramma strains on Asian corn borer（ACB） Eggs were studied under in-door and isolated net condition. The egg masses parasitism rate, the eggs parasitism rate and the number of eggs laidper female were compared. The results showed that parasitic effects of different Trichogramma strains were signifi-cantly different（P0.05） on ACB eggs of same basements material. Furthermore, parasitism of same Trichogrammastrain was also different on ACB eggs of two kinds of basements material. Trichogramma laid on ACB eggs masses offresh maize leaves was better than ACB eggs masses of mimeograph paper. Parasitic effects of Trichogramma wasthe best on ACB eggs of maize seedlings under isolated net, the eggs parasitism rate could reach 39.45%-70.48%.Through the test, S-AC strain and M-TC strain of Trichogramma of better parasitic effects have been selected,which could be used to control the 2nd generation of ACB.
