Extract

In May, 1956, large numbers of small caterpillars were found on Japanese plum trees in an orchard near Queenston in the Niagara Peninsula, Ontario. The owner stated that he first noticed them in 1955 when they got on his clothes while he was cultivating the orchard. In June, 1956, the caterpillars were also found on ornamental plum, Prunus cerasifera Ehrh. var. pissardii Koehne, in nurseries at Niagara-on-the-Lake and Fonthill by nursery inspectors.
