摘要：Some e xogenous compounds found in the environment alter the development of an organism from its usual path and worst, can cause embryonic abnormalities. Sp ecifically, this study sought to determine the effect of crude leaf extract of Cymbopogon citratus (lemon grass) on the developmental stages of Pomacea canaliculata (golden apple snail). Three experimental treatments ( i.e . 20%, 50% and 100% C . citratus ) , o ne negative control (water) and one positive control (molluscicide) were employed in the study. Results showed that crude extracts of C . citratus alters the normal growth of P. canaliculata by preventing the development of the embryo, altering the incubati on or hatching period of the egg and increasing mortality rates on both adult and juvenile stages. Moreover , leaf extracts of C. citratus is a valuable molluscicide since P. canaliculata is considered an invasive rice field pest. C . citratus is a potential organic substitute to synthetic molluscicide with no harmful effects to humans and to the environment
