NANTUCKET PINE TIP MOTH (Rhyacionia frustrana) - OKLAHOMA - Emergence of adults 90 percent complete in one pine plantation in Payne County. (Okla. Coop. Sur.). CONIFER SAWFLIES (Neodiprion spp.) - ARKANSAS - Emergence of N. taedae linearis heavy in northwest. Survival of material collected in southern area also good. Weather has been favorable for oviposition, and larval infestations in spring of 1965 may be high.
