Abstract
Part II addresses insect pests (by feeding type) and natural enemies of insect pests (including predators, parasitoids, and entomopathogenic fungi). Discussions of specific pests generally include identification, biology and life cycle, crop damage, monitoring and economic threshold(s), IPM strategies, and references. The topics included in Part II are as follows: Insect Pests / 70 Seedling and Root Feeders / 70 Seedcorn Maggot / 70 Wireworms / 71 Stem and Leaf Feeders / 73 Cutworms / 73 Leaf and Nodule Feeders / 75 Pea Leaf Weevil / 75 Leaf and Pod Feeders / 77 Grasshoppers / 77 Western Flower Thrips / 78 Twospotted Spider Mites / 79 Pod and Seed Feeders / 81 Lygus Bugs or Plant Bugs / 81 Pea Weevil / 83 Sap Feeders / 84 Pea Aphid / 84 Natural Enemies of Insect Pests / 86 Predators / 86 Lady Beetles and Ladybugs / 86 Lacewings (Aphid Lions) / 88 Minute Pirate Bugs / 89 Syrphid Flies (Hover Flies, Flower Flies) / 90 Parasitoids / 91 Parasitic Wasps / 91 Entomopathogenic Fungi / 92
