Extract

The phytophagous mite Oligonvchus bicolor (Banks) has been observed feeding on red oak, Quercus borealis Michx. f., at Kentville, N.S. It has not previously been reported in Canada east of Ontario. McGregor (1950) reported this mite as being found on chestnut, hickory, maple, oak and spruce in Connecticut, New Jersey, New York, North Carolina and Washington. Pritchard and Baker (1955) studied specimens taken from oak at Ithaca, N.Y., red oak at Hamden, Conn. and Washington, D.C., willow oak and white oak at Durham, N.C., and pin oak at Lawrence, Kansas. Garman (1923, 1940) found it common on oak and also present on chestnut, maple, hickory and birch. Johnson (1956) reported O. bicolor fairly common in Connecticut and believed its distribution to be the east coast of the United States. He stated that it was the most important mite species on chestnut in Connecticut and that when present occurred in large numbers. Caesar and Ross (1921) found O. bicolor heavily infesting ornamental oak trees in different parts of the Niagara district of Ontario.
