Abstract
Abstract Process for the prevention of chalkbrood disease amongst leafcutter bees (Megachile species) including the step of dusting the entrance of nesting holes with sodium sulfathiazole whereby incoming bees must come in contact with the powder upon entering the hole. Where old, previously used, beeboards are used as nesting holes, the process includes cleaning debris from the nesting holes and scouring the board with a dilute solution of calcium hypochlorite before applying the sodium sulfathiazole.
