Light infestations with patches of moderate were recorded throughout the Whiteshell Forest Reserve and north to Sasaginnigak and Family lakes. Collections were taken as far north as Molson and Big Stone lakes in . northern Manitoba, and throughout the Agassiz, Sandilands, and Northwest Angle Forest reserves. Moderate defoliation with patches of severe occurred from Victoria Beach south to the Gull Lake area, along the Bear River Road, at Otter Falls, Falcon Lake, and along No. 15 Highway near Vivian. Severe skeletonizing was confined mainly to aspen reproduction up to 3" d.b.h. In the southeastern part of Manitoba, moderate to severe defoliation was noted from the Zhoda-Vita area north and. west to Steinbach. and over an area of about 6 square miles north of Woodridge.
- 31 - 3.2.11 American Aspen Beetle, Gonioctena americana (Schaeffer):- Populations of this beetle remained at about the same level as last season. Light feeding was observed on trembling aspen in the Darwin area, near Dencross, at Lowlands, at Stead in the Belair Forest Reserve, and west of Pointe du Bois. Light to moderate defoliation of individual trees occurred near Black River, Wanipigow Lake, and Falcon Lake. In addition, it was observed feeding in conjunction with the aspen leaf beetle, C. crotchi at Gull Lake where defoliation by both species ranged from moderate to severe on smaller trees, and in the Agassiz Forest Reserve where the combined defoliation was light. 3.2.12 Large Aspen Tortrix, Choristoneura conflictana (Wlkr.):- The large aspen tortrix infestation at Island Lake in northern Manitoba subsided from moderate to severe in 1962 to patches of moderate defoliation in 1963. The infestation covered the peninsula between Cochrane and D'arris bays on Island Lake extending east to Bella Lake. Elsewhere, very low populations causing only traces of defoliation were recorded at Moar Lake. 3.2.13 Aspen Blotch Miner, Lithocolletis salicifoliella Chamb.:- There was an increase in populations of this blotch miner and samples were collected from trembling aspen at 35 widely scattered points. Light infestations were recorded at Crowduck, Caribou, Manigotogan, Aikens, Sasaginnigak, Gem, Family, Moat. , Elliot, Eardley, Weaver, and Gunisao lakes and near Stead in the Belair Forest Reserve. Light to moderate damage was noted at Caddy, Wallace, Siderock, and Viking lakes, near the junction of the Bird and Cat lakes Roads, along the Bear River Road, throughout the Agassiz Forest Reserve, along No. 15 Highway in the Vivian-Hazel Creek area, near Marchand in the Sandilands Forest Reserve, and throughout the Northwest Angle Forest Reserve. Moderate infestations covering several acres each were observed near Falcon Lake and 8 1/2 miles north of Pine Falls. 3.2.14 The Grey-willow Leaf Beetle, Galerucella decora Say:- There was a slight increase in populations in the vicinity of Wanipigow Lake, but elsewhere in the District the status of this insect remained much the same. Very light infestations, with skeletonizing ranging from a trace to light occurred at Otter Falls, Caddy Lake, Falcon Lake, and in the Northwest Angle Forest Reserve. Light skeletonizing of willow foliage was observed at Family, Caribou and Bird lakes, in the Brightstone area, near Catfish Creek south of Pine Falls, south of Hadashville, and near Marchand in the Sandilands Forest Reserve. At Telford, along the Bear River Road, and at Eardley Lake an occasional willow clump was moderately defoliated. Moderate to severe skeletonizing was recorded on the occasional willow clumps from Manigotogan area east to Wallace and south to Long Lake, and in the English Brook Wanipigow Lake area.
