Making control decisions for Sitodiplosis mosellana (Diptera: Cecidomyiidae) in wheat (Gramineae) using sticky traps
The Canadian Entomologist 134 (6), 851-854
Abstract: Experiments conducted in 1998 and 1999 in wheat fields in Manitoba and in 2001 in wheat fields in Manitoba, Saskatchewan and Alberta, Canada indicate that farmers can use sticky traps to monitor wheat midges (Sitodiplosis mosellana) in their fields and make accurate pest control decisions approximately 75% of the time. Ten traps spaced at 10-m intervals within the crop provide an effective sample size. Traps should be positioned at spike height, when wheat spikes are beginning to emerge, and left in place for 3 nights. Fields with 2 or fewer adults per 10 sticky traps rarely require an application of insecticide. High value wheat with an economic threshold of 4% infested seeds and trap catches of 3 or more midges per 10 sticky traps should be treated with insecticide.Wheat with an economic threshold of 7010% infested seeds should be treated when 4 or more midges are caught on all 10 sticky traps. Routine use of sticky traps to monitor the wheat midge would eliminate most unnecessary applications of insecticide and assure that benefits of insecticide application usually exceed costs.
