Abstract

 

Essential oils obtained from the leaves of Myrcia ovata Cambess., Psidium guajava L., Spondias purpurea L. and Plectranthus amboinicus (Lour.) Spreng. were gotten by hydrodistillation, analyzed by GC-MS and GC, and tested against third-instar Aedes aegypti larvae. The essential oils exhibited significant larvicidal activity with LC50 values ranging from 24.7 to 192.1 µg/ml. Larvicidal activities of 1,8-cineole and carvacrol, the major compounds of the essential oil from P. guajavaand P. amboinicus were also evaluated and their LC50 values were 47.9 ± 0.3 and 58.9 ± 0.4 µg/ml, respectively. The results of this study showed that these essential oils and their major compounds may be potent source of natural larvicides.

 

Key words: Myrcia ovata, Psidium guajava, Spondias purpurea, Plectranthus amboinicus, larvicidal activity, Aedes aegypti.
