Characterization of cyantraniliprole resistance in Spodoptera frugiperda: Selection, inheritance pattern, and cross-resistance to other diamide insecticides.

ABSTRACT:

Background

Cyantraniliprole, a diamide insecticide, is widely used in Brazil to control sucking and defoliating pests, including the fall armyworm (Spodoptera frugiperda), a major agricultural pest. However, increasing resistance to diamides has raised concerns about the long-term effectiveness of cyantraniliprole. This study aimed to (i) assess the evolution of cyantraniliprole resistance in field populations of S. frugiperda, (ii) investigate cross-resistance to other diamides, and (iii) analyze the role of the I4790K mutation in resistance mechanisms.

Results

A significant decrease in the susceptibility to cyantraniliprole was observed in field populations of S. frugiperda in Brazil, particularly in regions with intensive agricultural systems, such as the Brazilian Cerrad
