Acute Oral Toxicity of Fipronil on the Stingless Bee Frieseomelitta varia (Lepeletier, 1836)

Year: 2025

Type: article

Abstract: Stingless bees are essential pollinating insects, contributing to the maintenance of biodiversity and agricultural production. However, during their foraging activity, they encounter pesticides that can harm their populations. The present study aims to evaluate the acute oral lethal concentration (LC) of fipronil in the stingless bee species Frieseomelitta varia. The LC10, LC25, and LC50 were calculated for a 48-hour period, which were 61.2, 112.2, and 219.9 ng/mL, respectively, and for the 96-hour period, which were 15.07, 29.3, and 61.33 ng/mL, respectively. The study highlights the importance of the conscious use of pesticides, as damage to pollinating insect populations can be both economically and ecologically detrimental.
