Twelve clones of reed canarygrass ( Phalaris arundinacea L.) that were spray irrigated with municipal sewage effluent had a mean of 0.03 larva per clone of cereal leaf beetle ( Oulema melanopus L.) on 7 June 1974; similar unirrigated clones had a mean of 3.2 larvae per clone on that date. Also, the irrigated clones had fewer culms killed by the frit fly ( Oscinella frit L.) than unirrigated clones on 7 June and 12 Aug. 1974. Therefore, reed canarygrass as a receptor of sewage effluent, already the most acceptable species because of its flood tolerance, is even more desirable because there should be fewer numbers of these two important pests.
