Abstract: | Laboratory bioassays indicated that the potency of a nuclear polyhedrosis virus from Heliothis zea derived from a commercial American formulation was similar to that of a naturally occurring nuclear polyhedrosis virus from H. punctigera in Australia. Both viruses exhibited high virulence for neonate larvae of H. armigera and H. punctigera, the major pest species in this genus in Australia. Hence evaluation of the virus in Australia can proceed employing virus from either H. punctigera or H. zea. |
