ABSTRACT
Economics of egg production is vital for grainages since it is a commercial preposition which necessitates recovery of maximum number of laying with high fecundity. Attempts have been made to increase reproductive rate by multiple mating in Pure Mysore (PM), a multivoltine race and Kalimpong-A (KA) and NB4D2 , the bivoltine races of silkworm Bombyx mori L. The studies revealed increase in egg laying coefficient for multiple-mated moths of all three races. The possible mechanism in multiple mating which stimulates oogenesis and thereby reproductive rate is discussed.
Keywords: Bombyx mori L. Fecundity. Multiple mating.
