Numbers of hoary squash bee (Eucera (Peponapis) pruinosa) nests constructed over the 2017 and 2018 seasons in hoop houses in which one systemic insecticide treatment (either Admire-imidacloprid, applied to soil at seeding; or Coragen-chlorantraniliprole applied as a foliar spray; or FarMore FI400-thiamethoxam applied as a seed treatment) was applied to the Cucurbita acorn squash (Varieties: Table Star (2017), Celebration (2018)) crop 8-weeks before the bee active period, or the crop remained untreated as a control. Data presented are means ± SE across three hoop houses per treatment in each year.
