The present study reports to evaluation of effect of temperature on the acid and alkaline phosphates in the silk gland of fifth instars larvae. Variation in temperature significantly (P˂0.01) influenced the acid phosphates content of silk glands of multivoltine race of Bombyx mori and alkaline phosphates content was also considerably. The maximum level of acid phosphates is 5.25µg/mg and alkaline phosphates are 5.83µg/mg was found at 26±1ºC, while the minimum 3.26µg/mg acid phosphates 2.61µg/mg alkaline phosphates values were recorded at 10±1ºC. It appears that in the last phase of fifth instars when the silk glands are ready to synthesize the silk fiber, variation in temperatures alters acid and alkaline phosphates contents in the silk glands of Bombyx mori. Thus the 26±1ºC temperature, 12±1 hrs photoperiod and 80±5% RH is most suitable to enhance the activity of acid and alkaline phosphates in tissues and this may be biotechnological tool to boost the sericulture industries. Keeping this view and attempt has been made to study the effect of varying temperature regimes on the acid and alkaline phosphates enzyme activity in the silk gland of larvae of Bombyx mori Linn.
