Abstract

The study seeks to produce bio-insecticides/repellent from citrus peels extract and determine its efficacy on mosquitoes. The specific objectives were to; extract the essential oils - limonene from citrus peels of three citrus species and convert the fruits waste to useful product. Two extraction methods were adopted for study the extraction of the essential oils of the citrus peels: cold method of extraction and steam distillation (Clevenger-type apparatus). It has been observed (in this study) that yield of the orange oil was higher in steam distillation (Clevenger-type apparatus) and also higher in other citrus species than that of the Cold method. Steam Distillation, produced orange oil of almost two times more than cold method and also showed that the orange oil yield was five times more than the oil extracted by Cold method. It was also inferred that more oil was extracted from C. sinensis to C. lemon and C. aurantifolia. The distillate was colourless and cloudy in nature. The study recommended that there is need to use biotechnology tools to come up with methods that will extract higher quantity/higher percentage yield of the citrus essential oil so as to make economical valuable.
