USGA Summary Points:Moderate percentages of ABW adults (~ 40%) were removed with a single, low mown treatment (2.5 mm or 0.100). The effect of mowing on adult removal diminished with increasing mowing heights. Most adults (> 96%) survived mowing (all heights combined). Females were capable of ovipositing into the lowest putting green heights, though more eggs were placed outside the turfgrass stem or sheath as mowing height decreased. Adult activity on top of the turfgrass canopy was greatest when temperatures were between 14 and 18Ā° C (57 and 64Ā° F). Significantly more eggs were collected from moderate-fertility (0.1 lb N M-1 wk-1) treatments than low- or high-N treatments in choice tests. However, nitrogen fertility did not affect larval abundance in no-choice field studies. Larvae were capable of developing in all mowing height and fertility treatments. No significant differences in larval fitness were detected between treatments. Significant differences were detected in larval abundance (but not fitness) in plant growth regulated turf (trinexapac ethyl, trinexapac ethyl + ethephon) compared to untreated plots in 2017, but not 2018. Significantly more larvae were found in Primo plots than any other treatments in 2018. More research is required before conclusions can be made regarding the effect of growth regulation on ABW larval abundance and fitness
