Abstract:

Populations of the biting cattle louse, Bovicola bovis (L.), were intensively studied on 12 heifers representing four dairy breeds. Results of these studies demonstrated that this species was cyclic in occurrence reaching a peak of infestation during late January or early February, and that Holstein cattle were more heavily infested than either Guernsey, Jersey or Brown Swiss breeds. In an attempt to find factors affecting intensity of infestation and cyclic occurrence it was found that these phenomena were not associated with individual hair diameter or length, with density of hair per unit area of skin surface, or with ether-alcohol soluble skin secretions. A positive correlation, however, was found between hair thickness and population level within the Holstein breed. It was also demonstrated that the amount of skin scurf was greater during the summer months than during the winter months of high population levels.
