Info

Although no major moth flights were observed in urban areas in 1965, a substantial increase of adult moths was recorded in a light trap at Black Sturgeon Lake (Table 14). The most significant result of the trapping was the sharp increase in numbers of female moths captured (5998 in 1965 compared with 288)4 in 1964). TABLE 14 Summary of Recovery of Forest Tent caterpillar Adults from One Light Trap at Black Sturgeon Lake from 1961 to 1965 Year Males Adults recovered Females Total 1961 262 0 262 1962 2031 11 2042 1963 18248 29 18277 1964 10876 2884 13760 1965 38440 5998 44438 The sharp increase in the ratio of female to male moths was probably responsible for the marked increase in numbers of egg masses that occurred at numerous locations in the district (Table 15). On the basis of egg mass counts population levels of larvae will greatly increase in 1966 throughout the area of 1965 infestation. Egg counts also indicate that heavy infestation will spread into the southwestern part of the district. Light infestation is forecast for the Dog Lake and eastern Shebandowan areas (See photograph).

The highest populations occurred on balsam fir in Blackwell Township and at Black Sturgeon Lake where the number of colonies per tree averaged .5 and 1 respectively. The highest count (2.5 per tree) was recorded on several hosts in Inwood Township. In O'connor, Marks and Gillies townships small numbers were collected on white spruce trees. Red-headed Jack-pine Sawfly, Neodiprion virinianus complex One small pocket of medium-to-heavy infestation of this sawfly occurred on open-grown jack-pine trees at the Department of Highways headquarters on the Atikokan road. An average of seven colonies per tree was recorded and defoliation ranged from 40 to 75 per cent. Elsewhere in the district population levels were low.
