Fall Armyworm Symposium--1984: The Potential of Microbial Agents in Managing Populations of the Fall Armyworm (Lepidoptera: Noctuidae)
Abstract
The fall armyworm, Spodoptera frugiperda (J. E. Smith), is susceptible to at least 20 species of entomogenous pathogens. Some of these have the potential for a significant role in the management of the fall armyworm. Potential strategies include utilization of natural epizootics, application or introduction of pathogens as insecticidal agents, and use of pathogens in combination with other biological or chemical control agents. The nuclear polyhedrosis virus (NPV) of the fall armyworm has considerable potential for use in such strategies because of its high natural prevalence in fall armyworm populations and the possibility of epizootic enhancement through cultural manipulations of pasture systems. The potential of Bacillus thuringiensis Berliner, Nomuraea rileyi (Farlow) Sampson, Vairimorpha necatrix armyworm in agricultural systems also should be evaluated.Downloads
