Abstract:Traps utilizing powdered squash that contains cucurbitacins have shown promise as a reliable method of monitoring adult corn rootworm populations. This study describes the influence of varying amounts (0.05, 0.5, 5.0, and 50.0 mg/trap) of squash bait, either with or without cucurbitacins, on the catch of western corn rootworm, Diabrotica virgifera virgifera LeConte, and northern corn rootworm, D. barberi Smith and Lawrence, adults. Total number of beetles captured increased with increasing amounts of bait both without and with cucurbitacins, but the increase was greater with the latter bait. Additionally, as the amount of bait was increased, the male–female ratio increased, especially for the western species in the cucurbitacin treatments.
