A 41 STATUS OF INSECTS Ugly-nest Caterpillar, Archips cerasivoranus Fitch Population levels of this insect increased in the southern part of the district in 1965. The heaviest infestations occurred near the village of Alice in Alice Township and along Highway 41 near the village of Shady Nook in Stafford Township. In the former location larval colonies more than tripled in number compared with 1964 (Table 8). Moderate infestations were observed along the Madawaska-Cross Lake Road in Murchison Township and near Lake Dore in Wilberforce Township. Light infestations occurred along Highway 60 in Airy, Nightingale and Sherwood townships.

Population levels of this introduced casebearer have been low since 1954 Larval counts at eight locations are shown in Table 9.

A42 This insect is of European origin, and was first recorded at Northampton, Massachusetts in the United States in 1886. It has since spread throughout most of the range of larch in the eastern half of the United States and Canada. Surveys have continued to record changes in northern and western limits of distribution of this species in northern Ontario. The range extends through southern Ontario to Fort Frances District in the west and approximately 75 miles north of ;Ake Superior in the north. The adults emerge in late May to early July and lay one or more eggs. On hatching, the larva bores into the needle, feeds as a miner until September, then constructs a greyish cigar-shaped case. In the fall the larva hibernates on the twigs or trunk of the tree. Feeding resumes when the foliage begins to develop in April and, by the latter half of May, larval development is completed. The greatest damage occurs in the spring when the infested parts of the foliage withers and dies, European Spruce Sawfly, Diprion hercyniae (Htg.) An increase in population levels of this insect occurred at four of five sample locations in 1965 (Table 10). Light defoliation of open-grown white spruce trees was observed near Pretty Lake in Edgar Township. Little or no defoliation was observed elsewhere in the district. TABLE 10 Summary of European Spruce Sawfly Larval Counts in Pembroke District in 1964 and 1965 Total no. of larvae Location Av. d.b.h, of trees (township) in inches 1964 per 1-tray sample 1965 Alice 8 6 31 Cameron 8 27 39 Clara 6 32 23 Edgar 8 135 Maria 4 19 29 White-pine Shoot Borer, Eucosma gloriola Heinr. A decline in population levels of this borer occurred in the Beachburg Tract in Westmeath Township, In 1964, 51 per cent of the trees examined in a red pine plantation at this location were infested, and 21 per cent had infested leaders. In 1965, only five shoots were infested in the same plot and no leaders were attacked. Alder Leaf Miner, Fenusa dohrnii (Tischb.) A marked decline in populations of this leaf miner occurred in most of the district. However, moderate infestations were observed along the Ottawa River in Head Township, on the southwest shore of Shirley Lake in Preston Township and at Opeongo Lake in Dickson Township (Table 11). Light infestations persisted near the village of Whitney in Airy Township and along Highway 17 in Clara Township.
