Equipment and techniques have been developed to 1. Improve adult colony maintenance. 2. Collect, store, and hatch eggs. 3. Determine the number of larvae, mechanically dispersed, per unit of volume. 4. Dispense desired numbers of larvae automatically. 5. Rear broods of 1.3 million larvae, feeding them ground dog chow on a schedule of 0.2, 0.3, and 0.4 mg of food per larva on days 0 (day of hatching) through 2, respectively, and 0.6 mg per larva on days 3 through 7. 6. Concentrate pupae. 7. Collect and estimate numbers of adults from emergence cages. Each brood produced from 0.5 to 0.8 million adults within 11 days of hatching.
