Abstract

ABSTRACT Three acaricidal fumigants namely Folbex. Perizin and Frow mixture were evaluated, under local condition, for their efficacy against the tracheal mite disease of honey bees in aparies in N.W.F.P. The fumigants significantly reduced the number of sick bees and showed gradual increase in assumption of normal routine foraging than in the control where the colony population quickly dwindled resulting in complete collapse. Folbex strip fumigation proved comparatively economical and more effective. Perizin was better than Frow mixtures.
