Abstract

The painted bug, Bagrada hilaris, native to eastern and southern Africa and Asia, was detected in California in 2008, and it has spread rapidly throughout several southwestern US states. A polyphagous insect, it is particularly damaging to the billion dollar cole crop industry. B. hilaris frequently causes damage when it migrates to newly planted crops from weedy hosts. Feeding produces circular or star-shaped chlorotic lesions that become necrotic, and infested plants may be distorted. Currently, no reliable sampling methods for B. hilaris exist, nor are there effective natural enemies in the United States. Therefore, management has relied on multiple applications of insecticides and cultural practices such as removal of weedy hosts, destruction of crop residues, timing of planting, and use of transplants. Several pyrethroid and neonicotinoid insecticides are most effective for controlling the insect. Reliable sampling methods and further development of integrated pest management strategies to manage this invasive pest are urgently needed as its range continues to expand.
