    Notes: 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.

    Description: Use of remote sensing technology provided through the NASA/Wallops Chesapeake Bay Ecological Program was investigated by means of extensive interviews with users. Since the inception of the Program four years ago, the technology has been used in 136 different managerial projects. Sixty-five regional managerial agencies took part in projects that the authors categorized as socioeconomic, political/managerial, monetary, legal, and other. Remote sensing technology was considered successful in 88.6 percent of the completed projects and unsuccessful in 2.8 percent.
