摘　　要：为了进一步明确温度对锈翅蚁蛉(Myrmeleon ferrugineipennis)生长发育的影响,在恒温条件下研究了温度对锈翅蚁蛉试验种群生长发育的影响。结果表明:在15～27℃温度范围内,锈翅蚁蛉各发育历期随温度的升高而缩短,发育速率与温度呈显著正相关;在31℃下发育速率降低。不同温度下的存活率由高到低的顺序为27℃>23℃>19℃>15℃>31℃,1龄幼虫、2龄幼虫、3龄幼虫、幼虫期、蛹期的发育起点温度分别为6.33℃、11.55℃、8.30℃、8.42℃和7.24℃,有效积温为254.51、312.39、535.59、1164.20和574.01日.度。温度对锈翅蚁蛉种群的生长发育和存活率具有明显的影响。To explore the influence of temperature on the growth and development of M. ferrugineipennis, the growth and development of M. ferrugineipennis were observed at five temperatures （15℃, 19℃, 23℃, 27℃, 31℃） in the laboratory. The results showed that the developmental duration of M. ferrugineipennis increased with the rise of temperature from 15℃ to 27℃, and reduced at higher temperatures（31℃）. The generation survival rate of M. ferrugineipennis decreased in the order of 27℃〉23℃〉19℃〉15℃〉31℃, suggesting that the excessively high or low temperature was unfavorable to the survival. The developmental threshold temperature required for 1st instar, 2nd instar, 3rd instar, whole larval stage and pupal stage were 6.33℃, 11.55℃, 8.30℃, 8.42℃ and 7.24℃, while the effective accumulated temperatures were 254.51, 312.39, 535.59, 1164.20 and 574.01 degree-days respectively. It is so concluded that the influence of temperature on the developmental duration, survival rate and of experimental populations of M. ferrugineipennis is remarkable.
