Survey of Heterorhabditidae and Steinernematidae (Rhabditida, Nematoda) in Western Canada
A survey was done in the summer months along the Alaska Highway, in other parts of British Columbia, in northern Alberta, and in the Yukon Territory for steinernematid and heterorhabditid nematodes occurring in the top 10 cm of soil. Steinernemafeltiae and Steinernema spp. were found at 18 and Heter...
