Abstract
By exposing 4th and 5th instar larvae of inbred silkworm lines, the
effects of temperature changes on fecundity, incubation period, and fertility
of the silkworm egg lines were studied 2022 during autumn and spring at 10°,
14°,
18°,
26°,
34°,
and 38°C.
In contrast to the maximum fecundity rate of 386 eggs per female and the
incubation duration of 9.46 days at 26˚C, the minimum level of fecundity was
249 eggs per female and the incubation period of eggs decreased significantly
to 21.66 days at 10˚C. Fecundity and incubation time decreased significantly
over 26˚C. Temperature has been shown to negatively impact fecundity,
incubation, and fertility in inbred silkworm lines. The ideal temperature and
humidity for raising silkworm lines to produce seed cocoons is 26±1˚C with
80±5% humidity and 12±1 hours of light per day. This combination can be used
for hybridization and the production of more eggs and a shorter incubation
period for eggs with higher fertility. Studies revealed that fluctuations in
humidity and temperature during larval rearing led to a high frequency of unfertilized
eggs and a low fecundity rate. According to the study, temperature and humidity
changes can be avoided to improve fecundity, incubation, and fertility.
