This laboratory study tested combined effects of constant temperature and RF exposure on development of Aedes aegypti and Aedes albopictus from hatching to adult emergence. Temperature was reported as the primary determinant of developmental timing, with optimal development around 302C. RF exposure (900 MHz and 18 GHz) was described as a secondary factor that could accelerate or prolong development depending on temperature, with synergistic shortening at 250C and prolongation under suboptimal conditions.
