Western corn rootworm (WCR) is present in eastern Oregon, eastern Washington, and Idaho. As corn acreage in the region increases, WCR has the potential to become a serious pest. This publication covers how to identify WCR; its hosts and life cycle; its damage to corn; insect management; and resistance management.
Large raspberry aphid, Amphorophora agathonica, is an important pest in red and black raspberries in the Pacific Northwest. It transmits plant viruses that cause decreased cane vigor and fruit quality, making it a significant pest for growers. This publication includes aphid identification, biology, monitoring techniques, and control methods.
Most insects are not pests. Only those that feed on desirable plants or transmit disease cause problems for gardeners. Many insects are very useful. Some are pollinators of fruits, flowers, and vegetables, while others help control insect pests.
There are three types of beneficial insects: predators, pollinators, and parasitoids.
