R. aVariation in the susceptibility of bombyx mori L. to nuclear polyhedrosis with reared on different mulberry genotypes.h[electronic resource] c1991 aThe influence of host plant on the susceptibility of silkworm (SW) Bombyx mori larvae to a nuclear polyhedrosis virus (NPV) was investigated. Percent mortality and median lethal time (LT 50) of NPV were determined by bioassays. It was possible to determine Lt 50 only when SW fed on HN-64 hybrid. In this case the increase of infection was evident and hight contamination in the control was observed. The genotypes "Calabreza" and "Miura" were the most suitable with low percent mortalities (< 50 %). No virus contamination was observed when the control fed on "Calabreza". alarvae aAmora aBombyx Mori aLarva aMulberry aNuclear polyedrosis virus aVirus de poliedrose nuclear1 aALVES, S.
