Insect pest activity on the Eastern Shore for week ending June 25

Insect counts this week from the Blacklight trap in Painter, VA were as follows:
No corn earworms or armyworms; 4 European corn borer moths; 3 tobacco hornworm moths; 81 brown stink bugs; 8 green stink bugs. Thus, pest moth activity is low right now for all species; but brown stink bugs are quite active at present; probably flying out of wheat fields. These insects can cause serious damage to tomatoes, cotton, beans, sweet corn, and other crops. They move from crop to crop as fruit or pods form. Pyrethroid insecticides are often the cheapest and most effective control for these pests.

Thrips have been very active on crops with tobacco thrips feeding on the leaves of tomatoes and newly emerged beans; and flower thrips infesting the flowers of various crops. Some commercial tomato fields have experienced up to 5 thrips per bloom, which is very high. Some identifications of thrips samples brought to my lab have revealed that up to 50% of the flower thrips may be Western Flower thrips, Frankliniella occidentalis, which has been shown to flare up after repeated sprays from pyrethroid insecticides. Some other options for thrips control include Orthene on some crops like green beans, Radiant on most vegetables, Lannate, and most of the neonicotinoid insecticides (Provado, Actara, Venom, Assail, Belay, and Scorpion).
