Oxidative stress and hematocrit levels in eared doves (Zenaida auriculata) exposed to neonicotinoid-treated soybean cotyledons
This study evaluates the effects of exposure to neonicotinoid-treated soybean cotyledons on oxidative stress markers and hematocrit in eared doves (Zenaida auriculata). Thirty-two doves (eight by treatment) were exposed to cotyledons from soybean treated with imidacloprid (IMI1: 0.4 mg a.i./g seed a...

| description | This study evaluates the effects of exposure to neonicotinoid-treated soybean cotyledons on oxidative stress markers and hematocrit in eared doves (Zenaida auriculata). Thirty-two doves (eight by treatment) were exposed to cotyledons from soybean treated with imidacloprid (IMI1: 0.4 mg a.i./g seed and IMI2: 1.2 mg a.i./g seed) and thiamethoxam (TMX: 0.7 mg a.i./g seed), and cotyledons from untreated soybean as a control, plus commercial seed mix (maintenance food). The concentrations of neonicotinoids used corresponded to those typically applied in soybeans as seed treatment in the field with commercial formulations. The exposure to the chemicals was intermittent, alternating weekly over a four-week period. This design simulates real-world scenarios where birds may encounter both treated and untreated fields, as well as a variety of seeds. Results indicate no significant changes in hematocrit, hepatic and cerebral glutathione S-transferase (GST), hepatic catalase (CAT), or hepatic lipid peroxidation (LPO) levels across treatments compared to the control. The neonicotinoid concentrations used in soybean seed treatments appear to be insufficient to induce oxidative damage in these birds under intermittent exposure conditions. These findings underscore the importance of studying various exposure scenarios to better understand the potential environmental risks posed by neonicotinoid-treated seeds. |

Este estudio evalúa los efectos de la exposición a cotiledones de soja tratados con neonicotinoides sobre los marcadores de estrés oxidativo y los niveles de hematocrito en torcazas (Zenaida auriculata). Treinta y dos palomas (ocho por tratamiento) fueron expuestas a cotiledones de soja tratada con imidacloprid (IMI1: 0,4 mg i.a./g de semilla e IMI2: 1,2 mg i.a./g de semilla) y tiametoxam (TMX: 0,7 mg i.a./g de semilla), y cotiledones de soja no tratada como control, además de mezcla comercial de semillas (alimento de mantenimiento). Las concentraciones de neonicotinoides utilizadas correspondieron a las típicamente aplicadas en la soja como tratamiento de semillas en el campo con formulaciones comerciales. La exposición a los productos químicos fue intermitente, alternando semanalmente durante un período de cuatro semanas. Este diseño simula escenarios del mundo real en los que las aves pueden encontrar campos tratados y no tratados, así como una variedad de semillas. Los resultados no muestran cambios significativos en los niveles de hematocrito, glutatión S-transferasa (GST), catalasa hepática (CAT) o peroxidación lipídica hepática (LPO) entre los tratamientos en comparación con el control. Las concentraciones de neonicotinoides utilizadas en los tratamientos de semillas de soja parecen ser insuficientes para inducir daño oxidativo en estas aves en condiciones de exposición intermitente. Estos hallazgos subrayan la importancia de estudiar varios escenarios de exposición para comprender mejor los riesgos ambientales potenciales que plantean las semillas tratadas con neonicotinoides.
