  The Impact of Temperature Variations on Silkworm Growth Rate and Cocoon Production   1- Objectives The main object of this report is to find out how different temperature conditions affect the overall growth, molting and cocoon formation of the silkworm larvae. 2- Introduction Silkworms (Bombyx mori) are basically cold-blooded insects whose metabolic rates primarily depend on environmental temperatures. Optimal temperatures (23–26°C) accelerate growth whereas extreme conditions affect their development adversely. This study is an attempt: to examine, via experiment, how controlled temperatures influence larva growth speed and silk yield; and to determine what ideal temperatures are best for silkworm’s metabolism. 3- Material and Apparatus 15 healthy silkworm larvae (of 3 rd instar) Fresh mulberry leaves Thermometers Digital scale (.01g precision) 3 temperature-controlled environments: Group A: (Room temperature) Group B: (Heated incubator) Group C: (Cool cab...
