Seeding rate and water drainage were studied as alternate control measures for management of Hydrellia wirthi Korytkowsky on rice. Plants subjected to permanent flooding had more eggs, mines, and pupae per plant than those subjected to a weekly flush. Increasing the seeding rate from 100 to 300 kg/ha had no significant effect on the number of eggs, mines, and pupae per plant. Yields were not affected by H. wirthi damage.
