Aphids(Rhopalosiphum spp.) are very common pests in agriculture and are responsible for transmitting viruses, yellowing and leaf fall, which can lead to the total loss of a crop. In this way, integrated management with entomopathogenic fungi and natural pesticides has emerged as a sustainable alternative that is less harmful to the environment when compared to agrochemicals. In view of the above, the aim of this study was to evaluate the in vitro lethal action of eleven alternative pesticides and four species of entomopathogenic fungi (Beauveria bassiana, Beauveria brongniartii, Metarhizium anisiopliae and Metarhizium flavoviride) against aphids in order to offer a sustainable alternative for controlling these insects.
