Effect of different temperatures on the development of Clavigralla gibbosa Spinola (Hemiptera: Coreidae)

, : Effect of different temperatures on the development of Clavigralla gibbosa Spinola (Hemiptera: Coreidae). Bioecology and control of insect pests: Proceedings of the National Symposium on Growth, Development and Control Technology of Insect Pests: 105-108

The development of Clavigralla gibbosa was studied at 20, 25, 30, 35 and 40 degrees C and at variable room temperatures ranging from 16 to 26 degrees C in winter and 20 to 33 degrees C in summer. The average incubation period ranged from 3.4 to 11.3 days, with 75.8-81.2% hatchability at constant temperatures. There were 5 nymphal instars. The nymphal stage lasted 7.8, 11.3, 15.5 and 27.6 days and development took 11.2, 16.6, 22.7 and 38.9 days at 35, 30, 25 and 20 degrees C, resp.
