Brown marmorated stink bugs are increasing in our blacklight traps. I do not have any BMSB pheromone traps out this year, but it may be worthwhile to include a bifenthrin application.
Scout vineyards for spotted lanternfly now through the end of September. I observed an adult SLF on my home grapes this past week. Large populations can quickly fly into vineyards and remove large quantities of sap. Thresholds are 10 or more SLF per vine. Recommended insecticides include pyrethroids (watch pre harvest intervals! They vary between 1 and 30 days), Dinotefuran, thiamethoxam, and malathion.
