The efficacy of dusting honey bee colonies with powdered sugar to
reduce varroa mite populations
Journal of Apicultural Research Vol. 48 (1) pp. 72 - 76 publication
date: Feb 17, 2009
Amanda M. Ellis, Gerry W. Hayes, and James D. Ellis

> The objective of our study was to determine the efficacy of powdered sugar as a varroa control by comparing mite populations, adult bee populations, and brood area in untreated colonies with those in colonies dusted every two weeks for 11 months with 120 g powdered sugar per application. We found that dusting colonies with powdered sugar did not significantly affect the adult bee population. Within the limits of our study and at the application rates used, we did not find that dusting colonies with powdered sugar afforded significant varroa control.
