Neotropical Flora's Contribution to the Development of Biorational Products for Drosophila suzukii Control.

ABSTRACT

Essential oils (EOs) produced by aromatic plants belonging to different families, such as Asteraceae, Lamiaceae, Lauraceae, Myrtaceae, and Piperaceae, are generally suggested as potential sources of new molecules with insecticidal activity. The EOs are constituted bioactive molecules that may have to control Drosophila suzukii (Matsumura), a serious economic invasive pest of small fruits worldwide. Currently, the control strategy against D. suzukii depends especially on treatment with synthetic insecticides. Due to impacts to human health and the environment, efforts have been made to seek efficient insecticides in chemical pest control. Thus, sixty-five oils extracted from plants were selected to find new alternative types of insecticides active against D. suzukii. The monoterpenes, such as limonene, α-pinene, 1,8-cineole, linalool, menthol, geranial, and neral, were the most representative, which stand out for their insecticidal efficiency. The OEs demonstrated to be used in the management of D. suzukii, thus being an effective strategy to control this pest, ensuring crop protection and agricultural sustainability. Therefore, the substitution by natural products or eco-friendly pesticides instead of synthetic pesticides represents a notable option to mitigate harmful effects on human health and the environment.
