In past years, failure to control the first generation could result in damaging numbers in the second and third generations, when coverage is more difficult because of dense foliage. Currently, redbanded leafroller is again a minor pest. It has largely been replaced pesticide-resistant strains of obliquebanded leafroller. In the north central states, the redbanded leafroller usually produces two broods, and in many years a partial third brood develops. The insect overwinters as a pupa on the ground, in the leaves and other debris under the trees.
Moths emerge in the spring soon after the first green tissue shows in the buds.
They may be found until after bloom, but the greatest numbers are present in the late delayed dormant to pink bud stages. Moths are commonly found resting on the trunks and main scaffold limbs of the trees. In cold, windy weather, the moths are inactive and are usually found on the sheltered side of the trees. They fly only short distances when disturbed. Moths are most active on warm days, particularly in the afternoon.
