Resumen

This work aimed to evaluate the biocidal activity of extracts and oils from Azadirachta indica and Ocimum basilicum grown in Peru against three strains of adult Aedes aegypti. The chemical profile of these plant species was also determined using liquid chromatography/mass spectrometry. The aqueous, ethanolic, and hexane extracts from both species were toxic to the adults of A. aegypti, and concentration-dependent 100% mortality was achieved within 15–105 min. Moreover, the ethyl acetate extract of A. indica acted specifically on the strain Sullana (100% mortality in 40 min). In comparison, the essential oil from O. basilicum was toxic to all the strains (100% mortality in 15–30 min). In the chemical analysis, 32 compounds were identified in the O. basillicum, while 14 were described for A. indica. In conclusion, the biocidal potential of both plants grown in Peru against local A. aegypti adult strains was significant in terms of the eco-friendly advantages of botanical products.
