Summer's End Sparks Controversy Over Defoliation

Late-season defoliators, such as the orangestriped oakworm, may cause localized, heavy defoliation in trees during late summer and early fall. However, their impact on tree health is generally minor, and natural enemies help regulate their populations. Mechanical control, such as picking off larvae or removing eggs, is often sufficient. In severe cases, insecticides can be used, but timing and targeting are crucial to minimize impacts on non-target species. Overall, the damage caused by late-season defoliators is usually not a significant threat to tree health.
