Acute Contact Toxicity Test of Oxalic Acid on Honeybees in the Southwestern Zone of Uruguay

This work studies the acute contact toxicity of oxalic acid (OA) on a honeybee polyhybrid subspecies (Apis mellifera), which is the dominant biotype in southwestern zone of Uruguay (SWZU) and the country’s most important honey-producing region. We determined the mean lethal dose (LD50), as...
