HIGH NUMBERS OF COMMON ARMYWORM MOTHS. Dave Shetlar reported that high numbers of common armyworm (Pseudaletia unipuncta) moths are currently being captured in black light traps. Curtis Young also reported observing numerous adults at porch lights at least when the night temperatures were above 50F. The caterpillars of these moths feed on grasses. Sometimes these grasses are agricultural field crops (e.g. wheat and corn), and sometimes these grasses are turf-type grasses. This is especially significant to golf course superintendants, athletic field managers and home owners with turf adjacent to fields of wheat. Another aspect of this alert is there is little or no corn emerged in fields in many parts of the state and there is less winter wheat growing than in many preceding years, thus turfgrass may be more highly targeted this year
