Biological Control

Identifying Natural Enemies in Field Crops
This guide is divided into sections by major groups of natural enemies and spiders: beetles, true bugs, lacewings, predatory flies, parasitoids, spiders and ants. The plastic-coated 3.5 x 5 inch pages are made for field work (Michigan State University, 2006).
