Abstract:Samples of microarthropods from artichoke leaves, flower heads, and soil debris were taken from fields where growing conditions were similar except for insecticide treatment; fields were treated in Castroville and untreated in Carmel Valley, Calif. Methyl parathion and methidathion were applied every 2 wk for the control of the artichoke plume moth, Platyptilia carduidactyla (Riley), the major pest of artichoke. Pesticide-treated fields had eight fewer predatory and phytophagous microarthropod species. Anystis sp. Was absent; numbers of Parasitus bituberosus Karg and Pergamasus quisquiliarum Canestrini were reduced in treated fields. These mites are important predators of artichoke pests including first-and second-instar artichoke plume moth, thrips, aphids, and mites. A secondary outbreak of Tetranychus urticae Koch was observed in methyl parathion-treated fields. These factors should be considered in an IPM program for artichoke.
