EFICIÊNCIA DE BIOINSUMOS E INSETICIDA QUÍMICO NO MANEJO DE COLEÓPTEROS BROQUEADORES (COLEOPTERA) EM POMAR DE JABUTICABEIRA, EM HIDROLÂNDIA-GO.

Abstract

The jabuticaba tree (*Plinia* sp.) holds economic and sociocultural importance, particularly in producing regions such as Hidrolândia, Goiás, where the presence of wood-boring beetles can compromise orchard health and longevity. This study aimed to evaluate the performance of bio-inputs based on *Beauveria bassiana* and *Metarhizium anisopliae*—applied individually and in combination—against a standard chemical insecticide for the management of wood-boring beetles in a commercial jabuticaba orchard. The experiment followed a randomized complete block design with seven treatments and four replicates. Beetle populations were monitored using "PET Santa Maria" traps prior to applications and at 30 days after the first, second, and third applications. Evaluations covered capture dynamics over time, the relative efficiency of biological treatments compared to the standard chemical insecticide, and cumulative population pressure, estimated via the area under the curve (AUC). A significant reduction in captures was observed following the start of applications, with a significant effect of the evaluation period, although no consistent statistical differences were found among the treatments. In descriptive terms, the biological treatments showed relative efficiencies ranging from 85.71% to 100% after the first application and from 51.72% to 68.96% after the second. The lowest AUC values ​​were observed for *M. anisopliae* at 0.75 kg ha⁻¹ (3,210 beetle-days), *B. bassiana* + *M. anisopliae* (3,277.5 beetle-days), and *B. bassiana* at 1.0 kg ha⁻¹ (3,360 beetle-days), whereas the standard chemical insecticide showed 4,278.75 beetle-days. Although statistical superiority of the biological treatments was not demonstrated, the results indicate favorable performance of the entomopathogenic fungi and their potential for inclusion in Integrated Pest Management strategies for jabuticaba trees, especially when combined with population monitoring and other orchard management practices.
