Pulver parts of 15 Nigerian plants were used to determine survival, oviposition and emergence of adult blowfly, Chrysomya chloropyga, in laboratory. Eight of the plant materials were incorporated individually into the diet at 5% concentration of extract and used for survival studies while all the 15 plants were used to determine oviposition. Different larval instars were also exposed to plant powder-treated diets, and emergence was variously determined. More females survived than did males on the treated diets, with about 60% and 30% survival, respectively, with 25 day exposure. Both males and females survived poorly on diets containing Erythrophleum guineense, which decreased their emergence significantly. All the plant materials allowed oviposition that was however less than that of the control. All the plant materials significantly affected the emergence of adults from egg and larval Stages. Chromolaena odorata, Anacardium occidentle, Erythophleum guineense, Capsicum frutescens Piper guineense were the most effective in reducing the survival and emergence of C. chloropyga adults.
