" A 45 Red-headed Pine Sawfly, Neodiprion lecontei (Fitch) Infestations of this sawfly increased in intensity in 1965. High populations persisted in private plantations in Wilberforce and Cameron townships. Moderate infestations were observed along Highway 17 in Cameron, Clara, and Maria townships and light infestations occurred in Hagarty, Alice, and Wilberforce townships (Table 15). As in previous years, control measures using 2,5 per cent D.D.T, spray applied with pack sprayers, and the removal of colonies by hand pruning were carried out in private and crown owned plantations.

A medium infestation persisted in the central part of the district. Heavy infestations reported in Clara, Niven, and Fitzgerald townships in 1964 subsided in 1965. A light infestation occurred along the Hydro Electric transmission line in Bronson Township. A decline in population levels also occurred near Lake Traverse in White Township where 42 colonies were counted on ten trees in 1964 compared with 31 colonies in 1965. Six 6-foot jack pine trees were examined and tagged on May 15 in 1965 in an effort to determine the oviposition period. Examination of all the foliage on these trees revealed that oviposition did not occur in the fall of 1964. However, larval colonies were observed on all six tagged trees on July 5, 1965. Therefore oviposition occurred between May 15 and July 5. Further observations will be made in 1966. Red Pine Sawfly, Neodi prion nanulus nanulus Schedi. An increase in population levels of this insectoccurred in the northern and eastern parts of the district. Heavy infestations were observed on jack pine trees in the Beachburg Tract in Westmeath Township and near the main gate of Camp Petawawa in Petawawa Township (Table 16).
A46 Severe defoliation of red pine windbreaks occurred along Highway 17 in Cameron and Ross townships (see photograph). Moderate to severe defoliation of fringe red pine trees was observed in a private plantation near the village of Beachburg in Westmeath Township. These infestations were the first observed on red pine in the district since 1954.

Moderate defoliation occurred near the village of Petawawa in Petawawa Township and in the Beachburg Tract in Westmeath Township. A small pocket of medium infestation occurred in a woodlot near the village of Golden Lake in N. Algona Township (Table 17). Scattered colonies were observed in Buchanan and Richards townships.
