Effect of Phytoecdysteroid on Fecundity of Multivoltine Mulberry Silkworm Bombyx Mori Linn.

ABSTRACT

Effect of phytoecdysteroid on fecundity and hatchability of multivoltine mulberry silkworm Bombyx mori was studied. Experiments were performed by 40, 50, 60 and 70% concentration of phytoecdysteroid obtained from  Achyranthes leaf extract. A control set was always maintained with each set of experiment.The parameter selected for observation was fecundity of Bombyx mori. Maximum fecundity (423.33 ± 4.67) was noticed to be in case of the double treatment (IV and V instar larvae were treated) by 60% phytoecdysteroid concentration. Phytoecdysteroid treatment,if applied tactfully,may be useful for boosting up the sericulture industry as well as the economy of silkworm rearing.
