Nanoinsecticides of plant origin have advantages in the resistance of Aedes aegypti, vectors of infectious diseases. The objective of this study was to evaluate the insecticidal potential of Ayapana triplinervis essential oil nano-emulsions using in silico and in vivo assays in an Aedes aegypti model. Molecular docking showed that minority compounds present in the morphotype A essential oil have a more significant binding affinity to inhibit acetylcholinesterase and juvenile hormone receptors. Aedes aegypti adults were susceptible to A. triplinervis at 150 µg.mL-1 in a diagnostic time of 15 min for morphotype A essential oil nano-emulsion and 45 min for morphotype B essential oil nano-emulsion. The evaluation of toxicity in Swiss albino mice indicated that the nano-emulsions had low acute dermal toxicity and presented LD50 greater than 2000 mg.Kg−1. Thus, it is possible to conclude that nano-emulsions have the potential to be used in the chemical control of A. aegypti.
