Abstract

Use of abamectin for avocado thrips, Scirtothrips perseae, also has effects on the persea mite, Oligonychus perseae, and avocado bud mite, Tegolophus myersi, in Ventura County, California. In this study individual trees were treated with the standard insecticides for thrips, sabadilla (Veratran D) and abamectin (Agri-Mek), using a backpack sprayer, or left untreated. Sabadilla reduced S. perseae numbers on young and old leaves but failed to reduce O. perseae and T. myersi numbers. Abamectin significantly reduced numbers of all three pests. In addition, abamectin reduced the amount of leaf drop associated with O. perseae feeding. In a companion trial, where abamectin and sabadilla were applied by ground rig in one orchard and another orchard was left untreated, there were no differences in T. myersi populations. When all three pests are present, the use of abamectin may be a more efficient strategy than the use of sabadilla.
