The cold March weather has kept insect activity in small grains to a minimum. Aphids are very difficult to find and are almost all English grain aphids. Winter grain mite, though present in some fields, rarely causes issues, and only in dry, stressful years. Kentucky has also been seeing very low insect pressure and Kentucky Pest News has an excellent post on insect control and automatic insecticides, which you can find here: https://kentuckypestnews.wordpress.com/2018/04/03/unnecessary-use-of-pyrethroids-in-wheat-can-lead-to-aphid-resistance-and-barley-yellow-dwarf-virus-outbreaks/
