Resident populations of wild birds and caged quail, Colinus virginianus L., were evaluated to detect short-term effects from aerial applications of the nucleopolyhedrosis virus (NPV) of the gypsy moth. NPV in 2 formulations was sprayed on woodland plots in central Pennsylvania. Comparisons of prespray and postspray censuses of the common birds on the control and NPV-treated plots revealed no changes in populations of the wild birds that could be attributed to the NPV treatments. Data from 23 caged quail and 53 free-living birds showed no significant differences, or differences in trends, for any species between NPV-treated and control birds in organ weights or necropsy and histopathological rankings of the condition of organs and tissues. It was concluded that the aerial application of NPV had no short-term adverse effect on birds that contacted NPV during its application or that subsequently fed on NPV-infected gypsy moths or other NPV-contaminated food sources.
