Abstract
Field tests utilizing crude pheromone extracts fromRhyacionia frustrana, R. rigidana, R. subtropica, andR. buoliana showed thatR. subtropica andR. buoliana were mutually attractive.R. frustrana was attracted in low numbers to bothR. subtropica andR. buoliana, butR. subtropica andR. buoliana did not significantly respond toR. frustrana. R. rigidana did not respond to pheromone extracts from any otherRhyacionia spp., nor was it attractive to the others. Cross-attraction occurred among those species which were largely allopatric and shared few tree hosts.
