Abstract
Gel compositions of formic acid and a gelling agent such as fumed silica or polyacrylic acid have been prepared for controlling parasitic mites of honey bees. The gels provide slow-release capability and have been found effective against both Varroa jacobsoni and Acarapis woodi. They are advantageous in that they have improved handling characteristics and are safer than liquid formic acid, which is quite corrosive.
