| Abstract | ||||
| Five degree of temperatures was tested from 10 to 30˚C, Aphis craccivora, was reared on two statuses of bean leaves young and old (Nbrasca variety). Aphid insects were developed faster and had a higher mean relative growth rate and higher intrinsic rate of increase on young than on old leaves of bean, respectively. At temperature 25°C, it was more performance for aphid's development and rearing comparing by other degrees. The intrinsic rate of increase is strongly correlated with the mean relative growth rate during development for Aphis craccivora reared on both young and old leaves of bean plants from 10 to 25°C. | ||||
