Effect of mating duration on egg laying capacity and hatchibility of polyvoltine races of Bombyx mori Linn
Keywords:
mating duration, multivoltine races (pure mysore, c. nichi & hosa mysore) of silkwormAbstract
Moths of three polyvoltine (multivoltine) races, Pure mysore, C.nichi & hosa mysore of Bombyx mori were used to study the mating duration and use of male moths for repeated mating on fecundity, egg laying capacity and hatchability polyvoltine races of Bombyx mori eggs. No significant difference of fecundity was recorded when moths were allowed to mate 1,2,3,4 and 5 hours duration. However, significantly less viable eggs were not recorded when the mating duration was 3, 4 And 5 hours. It was observed that female’s moth that were mated with used males showed no significant differences in egg yield, hatchability and on fertilized eggs. Repeated mating can be followed at the time of shortage of males provided with some rest in between mating.
