Acaricidal activity of essential oil nanoemulsion against the African red mite (Eutetranychus africanus)

The African red mite (Eutetranychus africanus [Tucker]) is an important pest species of some economic plants. objective the present study was to evaluate effectiveness nanoemulsions consisting citronella grass, lemongrass, clove, and cinnamon essential oils their main chemical compounds against mite; toxicity, egg-laying inhibition, repellent effect on were determined. Essential oil (nEOs) prepared by mixing with different surfactants co-surfactants. Approximately 10 15 female mites transferred treated leaves placed soaked cotton kept in a Petri dish. Mite mortality number eggs laid checked after 24 h. As for repellency test, selected test consisted dipping half leaf into nEOs, while other dipped control (water). rate evaluated Results revealed that grass nEOs exhibited highly toxic only 0.6% concentration caused 100% mortality. Geraniol, one represented highest inhibition at 0.2% mean 0.1 egg compared 4.7 control. Furthermore, from 0.1% extremely 95% Therefore, nanoemulsion appropriate use effectively mite.
