Abstract

The developmental times, survivorship, longevity, fecundity, and life table
parameters of three aphid species namely, Rhop < /em>a/osiphum maidis (Fitch), Aphis
craccivora Koch. and Aphis nerii Boyer de Fonscolobe were investigated at two
constant temperatures 25 and 30°C. The data revealed that there was no significant variation in the
developmental time of R. maidis nymphs between the two tested temperatures, while,
these differences statistically occurred with A. craccivora and A. nerii. The survival
percentage of the three aphid species differed significantly between the two tested
temperatures. The higher survival percentage was observed at 30°C. The female longevity was decreased at 30°C more than at 25°C with the
three aphid species. The regression analysis indicated that the female fecundity rate
of R. maidis and A. craccivora at the two tested temperatures decreased gradually
with the older age of the female. This relationship was not found with A. nerii at both
25 and 30°C. From the obtained results, the calculated values of the mean generation time
(T) and doubling time (OT) of R. maidis, A. craccivora, and A. nerii were shorter at
30°C than at 25°C. The intrinsic rate of increase (rm) and finite rate of increase (A)
exhibited a similar trend. Meanwhile, the values of gross reproductive rate (GRR) and
net reproductive rate (Ro) were higher at 25°C than at 30°C for the three aphid
species.
