EFFICACY OF CALCIUM HYDROXIDE AGAINST NUCLEAR POLYHEDROSIS VIRUS OF SILKWORM, Bombyx mori

Abstract

                                Laboratory experiments were conducted to study the efficacy of calcium hydroxide against nuclear polyphedrosis virus (NPV) disease of silkworm, Bombyx mori L. Feeding the larvae with calcium hydroxide at 100 ppm treated mulberry leaves once during the third instar of B.mori was effective against NPV. Calcium hydroxide treatment did not produce any deleterious effect on the larval and cocoon parameters of B.mori.

Key words : Bombyx mori, Calcium hydroxide, NPV, Mulberry
