Fruit Insect Scouting

Plum curculio is active right now. New Jersey is reporting a bit less plum curculio activity than usual so far this year but expect that to change as we head into a cooler period. Imidan and Actara are both very effective on plum curculio per Dr. Anne Nielsen, and I suspect that Actara might also have some efficacy on scale crawlers although it is not labeled for such. Crawler emergence is typically in May, so the timing might not be appropriate. There is an excellent review on plum curculio management as an open access article here: Review of the Biology, Ecology, and Management of Plum Curculio (Coleoptera: Curculionidae) | Journal of Integrated Pest Management | Oxford Academic (oup.com).

Continue scouting for tarnished plant bug and two spotted spider mites.
