G 17 Red Pine Sawfly, Neodiprion nanulus nanulus Schedl. Population levels of this insect were highest since 1954 when nine colonies per tree were recorded near Sioux Lookout. Quantitative sampling revealed that the highest number of colonies occurred in Dewan Township Division 19 (Table 18). TABLE 18 Summary of Red Pine Sawfly colony counts on 10 Jack Pine Trees at Each Location in the Sioux Lookout District in 1965 Av, d.b.h of trees Location in inches Total no. of colonies found Vermilion Add, Twp. 3 2 Drayton Twp. 2 1 Dewan Twp. 3 6 Martin Road 2 2 Raven Lake 3 1 Pickerel Twp. 3 2 Black-headed Jack Pine Sawfly, Neodiprion pratti banksianae Roh. Appreciable numbers were collected for the first time in several years (Table 19). colonies were found commonly from Sioux Lookout to Ignace, the highest number occurring in Pickerel Township (see photograph). TABLE 19 Summary of Black-headed Jack Pine Sawfly Colony Counts on 10 Jack Pine Trees at Each Location in the Sioux Lookout District in 1965 Location Av. d.b.h. of trees in inches Total no of colonies found Drayton Twp. 2 3 Dewan Twp. 4 1 Pickerel Twp, 3 5 Hanna Lake 3 2 Frog Rapids 3 1 Kathryn Lake 2 3 Red-headed Jack Pine Sawfly, Neodiprion virginianus complex Little change on population levels of this insect has occurred for several years. Moderate to heavy infestations occurred on jack pine regeneration in Divisions 19, 25, and 32. The highest numbers of colonies were found near Medcalf Lake south of Lake St. Joseph and in Pickerel Township south of Sioux Lookout (Table 20).
G 18 Small numbers of Neodiprion nigroscutum Midd. were associated with Neodiprion virginianus complex larval colonies in Pickerel Township, TABLE 20 Summary of Redheaded Jack Pine Sawfly colony counts on 10 Jack Pine Trees at Each Location in the Sioux Lookout District from 1962 to 1965 Location Av. d.b.h. of trees in inches in 1 6 Total no. of colonies found 1962 1963 1964 1965 Jordan Twp. 2 2 8 13 2 Moonlight Falls 4 0 3 17 2 Wenasaga Road 4 2 2 11 3 Drayton Twp. 3 16 15 17 12 Pickerel Twp. 3 26 69 Martin Road 2 1 6 13 23 Raven Lake 4 3 3 6 2 Echo Twp. 2 19 Medcalf Lake 3 71 Yellow-headed Spruce Sawfly, Pikonema alaskensis Roh.
