E 8 STATUS OF INSECTS Gall Aphids on Spruce, Adelges spp. Several gall aphids on spruce increased considerably in numbers in the district in 1965. The pineapple gall aphid, Adelges lariciatus (Patch), which occurred only in small numbers in the past, was abundant in 1965 on open-grown white spruce trees in Division 44. The number of galls was particularly high on a few ornamental trees in the Town of Cochrane. Population levels of the eastern spruce gall aphid, Adelges abietis L., were high on Norway spruce near Iroquois Falls. An introduced species, Adelges strobilobius Kalt., occurred in appreciable numbers on black spruce trees in the southern part of Division 43, Birch Skeletonizer, Bucculatrix canadensisella cham. Infestations of the birch skeletonizer that occurred in the district in 1964 declined generally to light intensity. Light infestations persisted in most of the district south of a line from Abitibi Lake to Homuth Township. Within this area pockets of medium infestation were observed along lakeshores and in a few farm woodlots. Sharp declines in larval numbers were observed at several points in Division 43 following the leaf-mining stage of the insect. Larval development was retarded by the cold wet summer and some were found in the second moult on September 10. Larval counts at sample points were lower than in 1964 (Table 5.) Table 5 Summary of Larval counts of the Birch Skeletonizer on White Birch Foliage in. the cochrane District in 1964 and 1965. Note: Based on the examination of four leaves taken at cardinal points from each of five trees at each location. Location Date checked Total no. of larvae per leaf (township) in 1965. 1964 1965 1964 1965 Mortimer Sept. 1 211 128 11 6 Calder Sept, 3 156 108 8 5 Glackmeyer Sept, 3 91 52 5 3 Ogden Sept. 8 113 102 6 5 Hillary Sept. 8 57 46 3 2 Macklem Sept. 9 106 22 5 1 Average number of larvae A Pitch Midge, cecidomyia reeksi Vock. Populations of this insect have remained at a low level since 1962. No infested shoots were found in sample plots in Denton, Stimson, and Hepburn townships and minor increases in numbers of infested shoots occurred at four other sample points (Table 6).
