| 摘 要： | 在高温低湿（31 ℃，45% RH和34 ℃，45% RH）和低温低湿（16 ℃， 45% RH和19 ℃，45% RH）不同温湿组合条件下，以亚洲玉米螟卵为寄主，研究了不同地理种群玉米螟赤眼蜂的寿命、生殖力和性比情况。结果表明，在31 ℃，45% RH条件下，北京种群和日照种群平均每雌分别寄生(17.60±1.70)粒和(17.44±1.46)粒，显著高于其他种群（p＜0.05）。在19 ℃，45% RH条件下，广东广州种群寄生寄主卵数最多，平均每雌寄生(26.65±2.17)粒，与其他种群差异显著（p＜0.05）。北京种群、日照种群和广州种群分别可以作为高温低湿和低温低湿条件下防治亚洲玉米螟的候选种群。

| Abstract: | Longevity of female,fecundity and sex ratio of different geographic populations of Trichogramma ostriniae were investigated when reared on eggs of the Asian corn borer,Ostrinia furnacalis,at low temperature with low humidity(19℃,RH45%)and high temperature with low humidity(31℃,RH45%).The results showed that the Beijing and Rizhao populatioas parasitized 17.60±1.70 and 17.44±1.46 eggs per female,respectively,significantly higher than other populations(p＜0.05)at 31℃and RH45%.Guangzhou population parasitized 26.65±2.17 eggs per female,significantly higher than others(p＜0.05)at 19℃ and RH45%.These populations would be as candidates for controlling Asian corn borer at low temperature with low humidity or high ternperature with low humidity conditions. |
