摘要: 为探讨长额负蝗Atractomorpha lata云南曲靖种群卵的生长发育对环境温度的响应,在恒温16℃、19℃、22℃、25℃和28℃,相对湿度75%,光周期16L:8D试验条件下,观测长额负蝗成虫交尾取食油菜叶后所产卵块的孵化率、发育历期和发育速率,计算其发育起点温度和有效积温.结果表明:卵的发育历期随着试验温度升高而缩短.25℃时孵化率最高,为95.47%.根据直线回归法和直接最优法计算得出卵的发育起点温度与有效积温分别为11.69℃、406.91 d·℃和11.44℃、391.16 d·℃,并建立长额负蝗卵的有效积温预测式模型.

Abstract: The hatching rate, developmental epoch and developmental rate of egg masses laid by adult Atractomorpha lata after mating and feeding on rape leaves were observed at 16℃C, 19℃, 22℃, 25℃ and 28℃ with 75% relative humidity and a photoperiod of 16L:8D to investigate the growth and development of Atractomorpha lata eggs in response to environmental temperature in Qujing population in Yunnan. The results showed that the developmental period of the eggs shortened with the increase of the test temperature, and the hatching rate was 95.47% at 25℃. The starting temperature and effective accumulation temperature of eggs were 11.69℃, 406.91 day-degrees and 11.44℃, 391.16 day-degrees, respectively, based on the linear regression method and the direct optimum method, and the effective accumulation temperature of the eggs was predicted.

Key words: Atractomorpha lata, eggs, development duration, developmental threshold temperature, effective accumulated temperature
