In California rice, the key arthropod pest is tadpole shrimp. These vernal pool-adapted crustaceans are perfectly adapted to California's water-seeded rice system. They damage rice by uprooting seedlings and chewing on germinating seedlings. Management can be challenging because of reliance specific insecticides, leading to resistance, and their rapid growth under the right conditions. Using IPM approaches focused on scouting, proper use of insecticides, and biocontrol, there remain opportunities to sustainable manage this pest.
