Tobacco Insect Scouting Report. July 25, 2014

— Written By tcmclamb and last updated by

It is now week thirteen of scouting, and our one of our locations has begun harvest! There has been little change in insect activity, although there has been a slight decrease in budworm density and an increase in flea beetles populations. Since the tobacco plants are almost ready to harvest, the flea beetles numbers that we are seeing are of no significance and will not cause much damage to the plants. No pests are close to the threshold amounts.

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 – No data taken due to topping**

On Station, Rocky Mount – Control plants with no insecticide treatment
