Abstract Background: The emergence and spread of resistant strains of malaria vectors to chemical insecticides are becoming major problem for malaria vector management. Natural plant products play a vital role to resolve the current challenge of malaria control.Objective: The current study was conducted to evaluate insecticidal effect of ethnobotanical plant extracts against the primary malaria vector, Anopheles arabiensis in Northwestern Ethiopia.Methods: Primarily, ethnobotanical plants used for Anopheles mosquito control was surveyed in Dangur district, Northwestern Ethiopia. Insecticide susceptible strains of Anopheles arabiensis mosquito were reared in insectary of tropical and infectious diseases research center, Assosa university. The larvicidal and adulticidal potentials of frequently used plant extracts against susceptible strains of laboratory colony were evaluated.Result: A total of fifteen plants were identified as ethnobotanical plants helping the local people for mosquito control. Azadirachta indica, Ocimum lamiifolium, Ocimum americanum, Moringa olifiera leaf, and Moringa olifiera seed species of local plants were found to be frequently used to kill and/or repel mosquitoes in the study district. All the plant extracts were found to have potential larvicidal activity against 4th instar larvae of An. arabiensis and only ethanol and methanol extract of A. indica and O. lamiifolium were found to have potential adulticidal effect against adult of An. arabiensis. The highest larvicidal activity was observed in ethanol extract of A. indica with 95% larval mortality and lowest LC50 of 40.73 ppm and LC90 of 186.66 ppm. The highest adulticidal activity was observed in methanol extract of A. indica with 75% adult mortality at 300 ppm and lowest LC50 of 106.65ppm and LC90 of 1293ppm. The lowest larvicidal and adulticidal activity was observed in methanol extracts of O. lamiifolium with 63.35% larval mortality and leaf extract of M. olifiera with 50% adult mortality at 300 ppm, respectively.Conclusion: ethanol extract of A. indica exerted a remarkable larvicidal effect against An. arabiensis and thus it can be used for botanical mosquito insecticide development.

Leaf Essential Oil

Members of the genus Cinnamomum (Lauraceae) have aromatic volatiles in their leaves and bark and some species are commercially important herbs and spices. In this work, the essential oils from five species of Cinnamomum (C. damhaensis, C. longipetiolatum, C. ovatum, C. polyadelphum and C. tonkinense) growing wild in north central Vietnam were obtained by hydrodistillation, analyzed by gas chromatography and screened for antimicrobial and mosquito larvicidal activity. The leaf essential oil of C. tonkinense, rich in β-phellandrene (23.1%) and linalool (32.2%), showed excellent antimicrobial activity (MIC of 32 μg/mL against Enterococcus faecalis and Candida albicans) and larvicidal activity (24 h LC50 of 17.4 μg/mL on Aedes aegypti and 14.1 μg/mL against Culex quinquefasciatus). Cinnamomum polyadelphum leaf essential oil also showed notable antimicrobial activity against Gram-positive bacteria and mosquito larvicidal activity, attributable to relatively high concentrations of neral (11.7%) and geranial (16.6%). Thus, members of the genus Cinnamomum from Vietnam have shown promise as antimicrobial agents and as potential vector control agents for mosquitoes.
