Extract

In June of 1955 and 1956 a chrysomelid beetle was observed feeding on Duchess and Fameuse apple trees, wild grape, Vitis vulpina L., and red osier, Cornus stolonifera Michx., in an apple orchard at St. Jacques, Laprairie County, Que. The infestation was limited to approximately 100 apple trees in this orchard and the insect was not observed in other apple-growing districts of southwestern Quebec. Specimens of the pest were identified as of Rhabdopterus praetextus (Say) by Mr. W. J. Brown, Entomology Division, Ottawa. Infestations by this pest on apple in the province of Quebec have only once before been reported, by C. E. Petch in 1924 (Petch, 1925).
