Abstract
A new species of cytoplasmic-polyhedrosis virus, Smithiavirus pectinophorae sp. n. is described from the pink bollworm, Pectinophora gossypiella (Saunders). The LD 50 was 2500 polyhedral inclusion bodies (PIB)/mm 2 of available diet surface. Feeding larvae on virus-treated diets significantly reduced pupal weight, pupation rate, adult emergence, and may possibly reduce adult longevity, fecundity, and egg viability. The virus was successfully transmitted to the cabbage looper, Trichoplusia ni (Hübner); bollworm, Heliothis zea (Boddie); tobacco budworm, Heliothis virescens (Fabricius); but not to the southern armyworm, Prodenia eridania (Carmer); European corn borer, Ostrinia nubilalis (Hübner); lobster roach, Nauphoeta cinerea (Oliver); American cockroach, Periplaneta americana (Linnaeus); greater wax moth, Galleria mellonella (Linnaeus); and the house fly, Musca domestica Linnaeus.
