摘要: [目的] 探究影响喙尾琵琶甲繁殖性能的主要因素,为喙尾琵琶甲及该属昆虫的人工繁育提供依据。[方法] 从饲养温度、产卵基质颗粒大小和基质含水量等方面比较研究雌虫的平均日产卵量差异。[结果] 结果表明:饲养温度为20℃、室温(平均温度:21.8℃)、15℃、25℃时单雌日平均产卵量分别为4.790、3.919、2.151、1.568粒,20℃时雌虫的产卵量极显著高于15℃和25℃饲养条件下的平均产卵量,室温时的产卵量极显著高于25℃饲养条件下的平均产卵量,显著高于15℃时的产卵量。温度达到30℃时出现大量死亡;采用小颗粒产卵基质(>30目)时雌虫的平均产卵量显著高于基质颗粒过大(<30目)时的产卵量,基质颗粒>40目、30~40目、20~30目、10~20目、无基质时单雌日产卵均值分别为2.525、2.412、1.418、1.266、1.519粒;在含水量为10%~15%基质中的产卵量远多于其他含水量组,占总产卵量的68.49%。同时发现,喙尾琵琶甲产卵时间主要集中在00:00-06:00时间段,占全天产卵量的73.48%。[结论] 温度、产卵基质颗粒大小及含水量多少对雌虫的产卵量影响较大,雌虫对产卵环境具有极强的选择偏好性。20℃左右、小颗粒产卵基质(>30目)、基质含水量10%~15%等条件较适合喙尾琵琶甲产卵。喙尾琵琶甲在长期的进化选择下更偏好于在静谧的深夜产卵。

Abstract: [Objective] To provide theoretical basis for artificial breeding,an experiment was conducted to explore the main factors affecting the reproductive performance of Blaps rynchopetera Fairmaire. [Method] The difference of the average production per day of the female insects has been studied comparatively from the perspective of rearing temperature,the size of substrate and the water content of substrate. [Results] Daily egg yield per female under the condition of 20℃,room temperature (average temperature:21.8℃) 15℃,and 25℃ was 4.790 eggs,3.919 eggs,2.151 eggs,and 1.568 eggs,respectively.Fecundity was highest at 20℃ and very significant higher than the 15℃ and 25℃ treatments,the room temperature treatment was very significant higher than the 25℃ treatment and significant higher than the 15℃ treatment.When the temperature reached 30℃,the adults appeared mass mortality.When the oviposition substrate was small size (>30 mesh),the fecundity was significant more than large size treatment (<30 mesh).The substrate was 40 mesh,30-40 mesh,20-30 mesh,10-20 mesh and without substrate,daily egg yield per female was 2.525 eggs,2.412 eggs,1.418 eggs,1.266 eggs,1.519 eggs,respectively.The adults were sensitive to water content of oviposition substrate,it accounted for 68.49% of the total oviposition when the water content of substrate were 10% and 15%.Meanwhile,the laying peak was from 0:00 to 6:00,fecundity accounted for 73.48% of total output. [Conclusion] Rearing temperature,the size and water content of substrate have an obvious effect on fecundity of the female,the female Blaps rynchopetera Fairmaire has a strong environment selectivity when spawning.Around 20℃,small size of spawning substrate and 10%-15% water content of substrate are optimal spawning environment for Blaps rynchopetera Fairmaire.It shows that Blaps rynchopetera Fairmaire preferred spawning at midnight due to long-term evolution.

Key words: Blaps rynchopetera Fairmaire, fecundity, temperature, water content of substrate, substrate size
