Abstract: | Adults of Heliothis virescens infected with a cytoplasmic polyhedrosis virus (CPV) produced healthy offspring when their eggs were surface sterilized with either 15% formaldehyde or 0.2% sodium hypochlorite solution. Larvae from infected parents (1) cultured on a vitamin-deficient medium, (2) exposed to cold treatment (5°C, 24 hr), or (3) as progeny of adults from diapaused infected pupae, produced the same number of infected individuals as larvae reared in the customary way. Field studies indicated that the percent of CPV infection in larvae originating from virus-infected parents was density dependent. |
