摘　　要：为明确温湿度对多孔横沟象Pimelocerus perforatus卵生长发育的影响,室内分别观察比较8种温度、4种相对湿度条件下卵的发育历期和孵化率;并计算卵的发育起点温度和有效积温。结果显示:在相对湿度95%、光周期16L∶8D条件下,卵在10℃和35℃不能孵化,在15~25℃随温度升高发育历期逐渐减少,27~33℃时发育历期约为7 d;15~30℃卵的孵化率均在75%以上,33℃时孵化率约为14.46%;在较适温度27℃时,相对湿度45%和60%条件下卵不能孵化,而相对湿度95%条件下卵的孵化率为(84.81±6.88)%,发育历期为(7.24±1.28)d。适合多孔横沟象卵发育的温度为25~30℃,相对湿度为95%;卵的发育起点温度为(12.10±0.42)℃,有效积温为(114.99±3.42)℃。卵的发育速率与温度的关系符合二次回归方程V=-0.000359T 2+0.023T-0.233。To determine the effects of temperature and humidity on the growth and development of Pimelocerus perforatus eggs,the developmental duration and hatching rate were observed and compared at the eight temperatures or under four relative humidity in laboratory,respectively.The developmental threshold temperature and effective accumulated temperature of the eggs were calculated.The results showed that under the condition of relative humidity of 95%and photoperiod of 16L∶8D,the eggs could not hatch at 10℃and 35℃,the developmental duration gradually decreased with the increase of temperature within 15℃to 25℃,the developmental duration was about seven days from 27℃to 33℃,the hatching rate was more than 75%within the range of 15-30℃,and the hatching rate was only about 14.46%at 33℃.At the optimal temperature of 27℃,the eggs could not hatch under relative humidity of 45%and 60%,the hatching rate was(84.81±6.88)%and the developmental duration was(7.24±1.28)days under relative humidity of 95%.The temperature suitable for the development of P.perforatus eggs was 25-30℃,and the suitable relative humidity was 95%.The developmental threshold temperature was(12.10±0.42)℃,and the effective accumulated temperature was(114.99±3.42)℃.The relationship between development rate and temperature conforms to the quadratic regression equation V=-0.000359T 2+0.023T-0.233.
