| 摘 要： | 在实验室内以米蛾卵作寄主，观察了玉米螟赤眼蜂在5个恒温条件下(17，21，25，29，33℃)的发育羽化情况及成蜂寿命、产卵量和后代性比，实验中光照为14：10(L：D)，相对湿度控制为75％．结果表明，玉米螟赤眼蜂完成一代所需的发育时间随温度的升高而减少，在17℃时完成一代需要25．12d，而在33℃时仅需要8．11d；在17～25℃成蜂羽化率最高，33℃时最低，其次是29℃；雌蜂的寿命在17℃时最长为219h，但随温度的升高而缩短，在33℃时仅为19．20h；在21．25℃范围内，雌蜂产卵量达到最高；所设定的5个温度条件下发育的雌蜂，其所产的后代中雌性均超过雄性，后代雌性百分率在17～29℃达到高峰，但在33℃时有所下降．

| Abstract: | Trichogramma ostriniae Pang et Chen emergence, development time, longevity, fecundity and sex ratio were examined at constant temperatures of 17, 21, 25, 29, 33 ℃, 14∶10 (L∶D) and 75% relative humidity, developed in Corcyra cephaloica (Stainton) eggs in the laboratory. The percentage of emergency was the highest at 17-25 ℃, while the lowest was recorded at 33 ℃ followed by 29 ℃. The development time of the parasite decreased with increases in temperature. Mean female longevity of the adults ranged from 219 h at a constant temperature 17 ℃ to 19.20 h at 33 ℃. The highest fecundity was observed at 21-25 ℃. Females outnumbered males at all temperatures. The female percentage peaked at 17-29 ℃ and declined at 33 ℃. |
