DEVELOPMENT AND SURVIVORSHIP OF BIPRORULUS-BIBAX (HEMIPTERA, PENTATOMIDAE) UNDER A RANGE OF CONSTANT TEMPERATURES

The effect of temperature on the rate of development of Biprorulus bibax (Breddin) was determined by rearing individuals under a range of constant temperatures (15-37.5°C). Rates of development changed in a linear fashion over a wide range of temperatures. Estimates of lower developmental thresholds were obtained for all stages of development and for egg-adult (14.3°C). Fastest rates of nymphal and egg development occurred at 32.5 and 35.0°C, respectively. A requirement of 455.4 DD (degree-days) was estimated for development from egg to adult. Nymphal survivorship was highest at 25, 27.5, and 30°C; 41-63% survived from the first stadium to the adult stage at these temperatures. © 1990 Entomological Society of America.
