Biocontrole de formiga cortadeira do gênero Acromyrmex por fungos entomopatogênicos

Abstract: Formigas cultivadoras de fungos a partir de material vegetal fresco (Acromyrmex e Atta) apresentam grande importância econômica, por desfolharem severamente culturas agrícolas. O controle químico é o mais utilizado para o controle destas espécies, acarretando diversos problemas ambientais. Com isso existem uma preocupação e pressão da sociedade por alternativas de controle. Programas de controle biológico, utilizando fungos entomopatogênicos, estão sendo desenvolvidos no controle de insetos de forma promissora… Show more

“…In the control, mortality did not differ statistically from the values found when using the concentration of 1.0×10 4 spores mL -1 . Similarly, increasing the number of spores of M. anisopliae and B. bassiana caused a higher percentage of infection by entomopathogenic fungi in specimens of A. heyery (SANTOS et al, 2020) All spore concentrations used in this study were able to ensure infection and disease progression in leafcutting ant specimens. The spore concentration had a positive linear response with mortality since a higher concentration caused higher mortality.…”

“…This study presents promising results regarding the biological control of A. heyeri with the use of entomopathogenic fungi, considering that data on this interaction is already found in the literature (SANTOS et al, 2020). However, studies referring to lethal concentration values, which are a good indication of the fungi's efficiency, are missing.…”
