EFFECT OF TEMPERATURE ON REPRODUCTIVE AND EGG LAYING BEHAVIOR OF SILK MOTH BOMBYX MORI L.

In present investigation a study was conducted to determine the effect of changes in temperature on reproductive behavior, fecundity, site selection for egg laying and longevity of adult Bombyx mori L. crossbreed of PM X CSR2.The present investigation showed that adult of B. mori were died when kept at 40+ 5 o C and unable to lay eggs, at 30+ 1 o C they lay least number of eggs i.e. 2494 and died within 72 hours. At 10 + 1 o C they exhibit diapauses mechanism and delayed in egg laying showed higher number of egg laying i.e. 2619 and found live on the day15th of termination of experiment. No change in temperature cause normal reproduction behavior and laid highest number of eggs i.e.2922 and died after seven days. Silk worm prefer egg lying at the bottom of the beaker than upper side of beaker.
