In the present study, the effect of light rearing conditions on the susceptibility of the silkworm larvae to polyhedrosis viruses was investigated. The susceptibility of larvae reared continuously in the dark to a nuclear- and cytoplasmic-polyhedrosis virus inoculated perorally was much higher than that of larvae reared continuously in the light. This effect of light rearing conditions on the susceptibility to viruses was more conspicuously observed in larvae reared on fresh mulberry leaves than in those fed on artificial diet. Histological observations of the midguts from larvae reared under different light conditions suggested that different physiology of midgut was directly induced by the effect of light conditions of larval rearing, and thus made it possible to change the susceptibility of the silkworm larvae to viruses.
