本研究提示,在一定范围内,给食量越少,家蚕寿命越长。三个限食组全龄平均食量分别为对照组的25.6％、54.0％和76.8％,其幼虫寿命分别延长1.39倍、0.40倍和0.15倍。在不交配情况下,成虫平均寿命?>?,且限食组雌雄平均寿命都比对照组短。限食组发育不良。全龄日平均含量为对照组的25.6％者,幼虫死亡率高达47％,死笼率也高。分别在不同发育阶段限食,都能使幼虫寿命延长,连续限食者延寿幅度更大。前龄限食对此龄以后的生长发育所历时间无显著影响。限食组脱皮或结茧时间较离散。饥饿状态下,家蚕心率减慢。
This study suggests that within a certain range, the less the feeding amount, the longer the lifespan of silkworms. The average dietary intake of the three dietary groups was 25.6%, 54.0% and 76.8% of the control group, respectively, and their larval lifespan was increased by 1.39 times, 0.40 times and 0.15 times, respectively. In the absence of mating, the average life span of adults was >?, and the average life expectancy of males and females in the restricted diet group was shorter than that of the control group. The food restriction group is stunted. The average daily age of the control group was 25.6%. The larval mortality was as high as 47%, and the mortality rate was high. Limiting food intake at different stages of development can extend the lifespan of larvae and increase the duration of life for those who are continuously restricted. There was no significant effect of the age-before-age restriction on the growth and development time after this age. Limit food group peeling or scarring time is more discrete. In the state of starvation, the heart rate of silkworms slows down.
