Topical toxicity of four active ingredients on Atta sexdens workers

Research, Society and Development, 2022

Pathogenicity of filamentous fungi towards Atta sexdens rubropilosa (Hymenoptera: Formicidae)

International Journal of Tropical Insect Science, 2021
In the Neotropics, leaf-cutting ants are pests of great importance to various crops. The natural defenses and complexity of these ants reduce the impact of potentially useful pathogens for biological control. Furthermore, several types of research with entomopathogenic fungi usually focus on only a few isolates of well-known species, like Beauveria ...
