Abstract
From 1945 to 1949 tests were conducted at Ottawa to determine whether certain of the more commonly grown commercial varieties of onions are resistant to the onion maggot, Hylemya antiqua (Meig.). Sleesman (1934), from the results of field tests in Ohio, had concluded that some varieties of onions do support significantly higher populations of the maggot than others.In 1945 and 1946 at Ottawa, 17 varieties of onions were tested; in 1947, 1948, and 1949 the number was reduced to nine, which are listed in Table I.Keywords
