Cold Shock Response in Biological Traits of the Silkworm, Bombyx mori

In response to the ambient temperature, insects' physiology and behaviour change just like those of all other living things. For this investigation, FC1 X FC2 double hybrid silkworm strain/breed was used. The larvae were collected on third day their fifth instar put in little paper trays for a one-hour cold shock treatment at 10, 15 20°C with relative humidity 75±5% B. O. D. CS-induced allowed recuperate an hour room temperature. Compared control (2.16 g) larvae, average weight recorded 2.30, 2.31, 2.2 g, which correspond 15, 20°C, respectively. When compared group, population created from 10°C demonstrated ERR improvement 70.83 percent (67.50 percent). However, 15°C respectively, elevated 86.67 75.83 noted. Mortality 11.67% between 10 15°C, whereas it 12.50% 20°C. ability transition into next instar, spin cocoon, become pupa eventually moth utilised assess cold's potential impact larval, pupal, adult mortality. Highest cocoon 1.37 g observed 15°C. Weights cocoons measured (1.30 g), corresponds temperatures made by CS had shell weights 0.22, 0.24, 0.19 0.30 control. Temperature 15°Cshowed higher efficiency traits studied showed slight decline traits. As result, we inferred that exhibited profound temperature can be used develop strains temperate areas.
