Some Aspects of the Biology and Dispersal of the Pine Tortoise Scale, Toumeyella numismaticum (Pettit and McDaniel) (Homoptera: Coccidae)

Abstract

The senior author conducted this investigation during 1937 and 1938 in the Sandilands Forest Reserve, Manitoba. The results were presented in an unpublished report (Rablrin, 1938). Owing to the current importance of this insect in Manitoba and the Lake States of the United States, it was considered advisable to publish those aspects of the work relating to life history and dispersal. This was undertaken by the junior author.
