Abstract
The prevalence of nuclear polyhedrosis virus and granulosis virus was determined in populations of the noctuid Spodoptera frugiperda (J.E. Smith) in south-eastern Louisiana in 1979 and 1980, in pastures and in fields of maize and sorghum. Both diseases reached their peak mean infection rates in mid-August in S. frugiperda infesting pastures, the nuclear polyhedrosis virus at 50.8% and the granulosis virus at 2.8%. The polyhedrosis virus prevalence in some pastures peaked at 60-68%. Infection rates for polyhedrosis virus in larvae on maize and sorghum were initially lower than in pastures, but were similar after mid-July on maize or late July on sorghum. Low levels of infection by a mermithid nematode, a microsporidium and the fungus Nomuraea rileyi were also found
