Interpretive Summary: Novel plant derived biological compounds with insecticidal activity are needed to support the development of new sustainable pest insect control practices. This work presents the evaluation of insecticidal activity of a volatile oil fraction from the Piper betle plant leaf against the Aedes aegypti mosquito. This volatile oil extract had mosquitocidal activity on larvae and ovipositional repellency to adults. Analysis of the genetic response of this insect demonstrated disruption of regulation of gene expression in genes linked to chemical detoxification pathways. The insecticidal activity is being further evaluated for broader application to other vector insects like hemipteran pests in crop production.

Technical Abstract: Novel plant derived biological compounds with insecticidal activity are needed to support the development of new sustainable pest insect control practices. Chemical analyses of bioactive plant compounds from Piper betle leaves, had insecticidal effects on the insect vector, Aedes aegypti. Analyses of extracts of the oils produced larvicidal effects and ovipositional repellency of adult females. Chemical analyses of the natural bioactive compounds identified several chemicals that disrupted the genes in insect detoxification pathways. The insecticidal activity is being further evaluated for broader application to other vector insects like hemipteran pests in crop production.
