Laboratory rearing of Notonecta undulata Say (Hemiptera: Notonectidae)

Four generations of Notonecta undulata Say were reared in the laboratory within a year. Adults were kept in 15 gallon oviposition aquaria maintained at a temperature of 25 +/- 1∞C and a pH of 6.5 - 7.5. Eggs were transferred to an incubation aquarium kept under identical conditions. Nymphs were reared individually in 100 ml glass beakers. Live prey were supplied regularly for food.
