Larvicidal efficacy of Coconut Fruit Fiber (Cocos nucifera L.) and Pineapple peels (Ananas comosus L.)

ABSTRACT

The over use of synthetic insecticides for mosquito control, contaminates natural ecosystem and its inhabitants. Botanical resources are promising alternatives for pests and vector control due to their environmental compatibility, high biodegradability, target specificity, and zero resistance culture. Therefore this study investigated the larvicidal potency of aqueous and ethanolic extracts of Cocos nucifera fiber (CNF), Ananas comosus peels (ACP) and their synergy of 1:1 mixture against Cx. quinquefasciatus larvae. Qualitative phytochemistry of both plants were examined. Cx. quinquefasciatus 3 rd instar larvae were subjected to different concentrations of 500ppm, 750ppm and 1000ppm for 24, 48 and 72hrs exposure time. Data was analysed statistically using Analysis of Variance (ANOVA).
