Chemical composition and larvicidal activities of essential oil of Cinnamomum camphora (L.) leaf against Anopheles stephensi

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

INTRODUCTION

Anopheles stephensi is the main malaria vector in Southeast Asia. Recently, plant-sourced larvicides are attracting great interests.

METHODS:

The essential oil was extracted from the leaf of Cinnamomum camphora (L.), and a bioassay was conducted to determine the larvicidal efficacy. The chemical composition of the essential oil was determined by GC-MS analysis.

RESULTS:

The oil showed strong, dose-dependent larvicidal activities. The onset of larvicidal efficiency was rapid. The LC50 and LC95 were determined as 0.146% and 1.057% at 1 h, 0.031% and 0.237% at 12 h, 0.026% and 0.128% at 24 h, respectively. The oil contains 32 compounds.

CONCLUSIONS

The essential oil of C. camphora leaf has an excellent larvicidal potential for the control of A. stephensi.
