Topical toxicity of four active ingredients on Atta sexdens workers
Leaf-cutting ants are economically important pest insects in the Neotropical region. They forage on fresh leaves and flowers that serve as substrates for the cultivation of their mutualistic fungus, which they feed upon. The main active ingredient for their control is sulfluramid, but the restriction of its use is under discussion.

Histopathological effects of cypermethrin and Bacillus thuringiensis var. israelensis on midgut of Chironomus calligraphus larvae (Diptera: Chironomidae) [PDF]
Pesticides are extensively used for the control of agricultural pests and disease vectors, but they also affect non-target organisms. Cypermethrin (CYP) is a synthetic pyrethroid used worldwide. Otherwise, bioinsecticides like Bacillus thuringiensis var.

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