Download2003
Borden, J. H., Delury, L. E., Judd, G. J. R., Evenden, M. L.
Abstract: We tested several methods for assessing the mating status of male obliquebanded leafrollers, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae). In four experiments, we established that the technique developed to determine mating status of male spruce budworms, Choristoneura...
