Least squares means within a column followed by the same number are not significantly different between weeks within a location for a single treatment. Least squares means within a row followed by the same lowercase letter are not significantly different between trap crop treatments within a location for a single week. Least squares means within a column followed by the same uppercase letter are not significantly different between locations within a treatment for a single week.
