Abstract: The aim of the study is to evaluate the bio-efficacy of white flesh Citrus grandis fruit peel extracts, essential oil and isolated compounds against late third instar Aedes aegypti larvae. Furthermore, this study also investigates its effect on non-target organisms. Bioassay was conducted under laboratory condition to determine the LC50 and LC90 values at 24 and 48 hours post treatment. The most toxic extract was tested at sub-lethal dose against non-target organism namely, Toxorhynchites splendens and Poecilia reticulata. Results revealed that the hexane extract proved to be the most effective with lowest LC50 values at 24 hours (17.98 ppm) and 48 hours (10.19 ppm). The extract is proven safe when tested with P. reticulata but toxic towards younger instar of Tx. splendens. The finding indicates that white flesh C. grandis fruit peel has the potential to be used as alternative larvicides against Ae. aegypti larvae.
