We prove the existence of at least one solution x 2 AC(0,1]
(absolutely continuous on (0,1]) of the quadratic integro dif-
ferential Eq. (1) with the initial condition (2) where the func-
tions fi(t,x(t)), i= 1, 2 are L1-Caratheodory functions. Our
proof depends on the measure of noncompactness. In fact,
our result in this paper is motivated by the extension of the
work of El-Sayed and Hashem [13].
