Abstract: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 well as the no observed effect level (NOEL) and the lowest observed
effect level (LOEL) values. We also estimated the total number of honeybees per hive in the test area. The aim was to assess
the relationship between the maximum OA dose used in Uruguay (3.1 g OA per hive) and the toxicological parameters of
honeybees from SWZU. The current dose of 3.1 g OA per hive corresponds to 132.8 µg OA per honeybee since determined
NOEL is 400 µg OA per honeybee; our results indicate that the current dose could be increased to 9.3 g OA per hive. The
results also highlight some differences between the LD50 value in SWZU honeybees (548.95 µg OA per honeybee) and
some published LD50 values for other honeybee subspecies.
