Cedar Leaf Miners, Argyresthia spp. 33 STATUS OF INSECTS A further decline in population levels of cedar leaf miners (four species) occurred in 1965. The medium infestations which were reported in Leeds, Grenville, Dundas, Carleton, and Lanark counties in 1964, subsided in 1965. Light infestations persisted on roadside hosts in Dalhousie Township and on cedar windbreaks in the Kemptville Nursery in Oxford Township. Pine Tube Maker, Argyrotaenia pinatubana Kft, The pocket of heavy infestation which occurred on white pine reproduction in a privately-owned woodlot in Mountain Township in 1964, declined to light intensity in 1965. Small numbers were observed in the Larose and Limerick forests and in Beckwith and Goulbourn townships, Birch Leaf Skeletonizer, Bucculatrix canadensisella Cham. In 1964, pockets of heavy infestation occurred in Lanark and Carleton counties, and light infestations were observed west of Brockville, and along the shorelines of the Ottawa River between Ottawa and Hawkesbury. However, in 1965 numbers declined to such low levels that larvae could not be found. A Miner on Ironwood, Chrysopeleia ostryaella Cham. Pockets of light to medium infestation of this miner, on ironwood were observed commonly in the district, but population levels were generally lower than in 1964. Medium infestations occurred in Nepean, Mountain, and Wolford townships. Light infestations were recorded in Goulbourn, Oxford, Finch, North Gower, and Beckwith townships. Larch Casebearer, Coleophora laricella (Hbn.) This introduced pest of tamarack and European larch maintained its low incidence that has prevailed over the past decade since the introduction and establishment of at least two European parasites (Table 8).

A 34 Pitted Ambrosia Beetle, Corthylus punctatissimus (Zimm.) This beetle continued to cause mortality in sugar maple reproduction. Sample points were established at locations in Beckwith, Goulbourn, Mountain, and Wolford townships, to study population trends (Table 9).

Elsewhere in the district varying degrees of infestations were observed, particularly on ornamental and shade trees in towns and villages. European Spruce Sawfly, Diprion hercyniae (Htg.) Larval populations of this sawfly remained at a low level. Although no visible defoliation of host trees occurred, small numbers of larvae were recovered in tray samples (Table 10).
