A Nuclear Polyhedral Virus of Catopsilia Pomona in Papua and New Guinea.

Abstract

A virus located at Popondetta in the Northern District of Papua affecting the larvae of Catopsilia pomona is a new record and the virus belongs to the nuclear polyhedral group of insect viruses. The virus appears to be restricted to C. pomona and readily infects with resulting death all larval stages of C. pomona. The polyhedra range from 1,000 to 2,000 mp in diameter with an average diameter of 1,170 mp. A prepared suspension was still highly infectious aft.er seven months when stored in suspension in the laboratory, but persistence in the field could not be maintained for a long period.
