Overwintering Colorado Potato Beetle adults are beginning to emerge in southcentral Idaho -- both Eastern and Western Magic Valley. Confirmed areas include Rupert, Minidoka and Twin Falls.
The overwintering adult stage does limited damage, however, females are beginning to lay eggs in potato fields. We could see the damaging larvae appear in about 7 to 10 days depending on temperatures. Growers that did not apply an effective systemic insecticide at planting should be watching for the egg hatch to time a foliar spray for the first generation of CPB larvae.
