Tobacco Insect Scouting Report. August 4, 2014

— Written By tcmclamb and last updated by

It is week fourteen of our weekly scouting program, and numbers remain low. Flea beetle numbers have increased somewhat but are still low enough to not cause any substantial damage. We have observed a few a tobacco budworm larvae, mostly on suckers. Most sites are now starting to harvest and we expect to see more flea beetles, and some hornworm pressure within the next couple of weeks.

Here are the scouting reports from the control plots for our experiments at the Upper Coastal Plain Research Station near Rocky Mount, NC and the Lower Coastal Plain Research Station near Kinston, NC. For some of these experiments, the control plots receive no insecticide treatments for the entire season. For some of the experiments, we are interested in only caterpillar pests so all plants in the experiment, including the control plots, are treated in the greenhouse with imidacloprid to prevent other early season pests.

On Station, Kinston – Control plants with no insecticide treatment
