本文测试了不同温度（22℃、25℃、28℃）和不同光周期（LD11：13,LD12：12,...,LD15：9）对甜菜夜蛾发育历期和繁殖的影响。结果表明：随着温度升高,甜菜夜蛾卵期、幼虫期、蛹期、蛹重都呈下降趋势,温度对卵期、幼虫期、蛹期、蛹重都有显著影响（P=0.000）。随着温度升高,每雌产卵量呈上升趋势,温度对每雌产卵量有显著影响（P=0.004）;随着温度升高,雌虫寿命呈下降趋势,温度对雌虫寿命有显著影响（P=0.001）;雄虫寿命也呈下降趋势,但温度对雄虫寿命没有显著影响（P=0.289）。在22℃、25℃、28℃条件下,在所有的光周期下,甜菜夜蛾滞育率都为0,没有光周期反应。在22℃条件下,不同光周期幼虫期、蛹期存在显著差异（P=0.002,P=0.011）,蛹重没有显著差异（P=0.171）;在25℃条件下,不同光周期幼虫期、蛹期、蛹重都无显著差异（P=0.973,P=0.069,P=0.862）;在28℃条件下,不同光周期幼虫期没有显著差异（P=0.207）,蛹期、蛹重存在显著差异（P=0.000,P=0.006）。
本文測試瞭不同溫度（22℃、25℃、28℃）和不同光週期（LD11：13,LD12：12,...,LD15：9）對甜菜夜蛾髮育歷期和繁殖的影響。結果錶明：隨著溫度升高,甜菜夜蛾卵期、幼蟲期、蛹期、蛹重都呈下降趨勢,溫度對卵期、幼蟲期、蛹期、蛹重都有顯著影響（P=0.000）。隨著溫度升高,每雌產卵量呈上升趨勢,溫度對每雌產卵量有顯著影響（P=0.004）;隨著溫度升高,雌蟲壽命呈下降趨勢,溫度對雌蟲壽命有顯著影響（P=0.001）;雄蟲壽命也呈下降趨勢,但溫度對雄蟲壽命沒有顯著影響（P=0.289）。在22℃、25℃、28℃條件下,在所有的光週期下,甜菜夜蛾滯育率都為0,沒有光週期反應。在22℃條件下,不同光週期幼蟲期、蛹期存在顯著差異（P=0.002,P=0.011）,蛹重沒有顯著差異（P=0.171）;在25℃條件下,不同光週期幼蟲期、蛹期、蛹重都無顯著差異（P=0.973,P=0.069,P=0.862）;在28℃條件下,不同光週期幼蟲期沒有顯著差異（P=0.207）,蛹期、蛹重存在顯著差異（P=0.000,P=0.006）。

Effect of temperature and photoperiod on developmental period and reproduction of Spodoptera exigua.The results showed that egg stage,larval stage,pupal stage,and pupal weight declined as the temperature increased from 22℃ to 28℃.Temperature had significant effects on egg stage,larval stage,pupal stage,and pupal weight（P=0.000）.Egg production per female increased as the temperature increased,the temperature had significant effects on egg production per female（P=0.004）.The longevity of female declined as the temperature increased,the temperature had significant effects on the longevity of female（P=0.001）.The longevity of male also declined as the temperature increased,but the temperature had no significant effects on the longevity of male（P=0.289）.The diapause of Spodoptera exigua is 0% in different photoperiod at 22℃、25℃ and 28℃.It is not photoperiodic response.It had significant effects on larval stage and pupal stage（P=0.002,P=0.011） and had not significant effects on pupal weight（P=0.171） in different photoperiod at 22℃.It had not significant effects on larval stage、pupal stage and pupal weight in different photoperiod at 25℃（P=0.973,P=0.069,P=0.862）.It had not significant effects on larval stage（P=0.207） and had significant effects on pupal stage and pupal weigh（P=0.000,P=0.006） in different photoperiod at 28℃.
