Alexis Ballis in France recently completed a trial on using drone trap frames. It's in French. http://www.bas-rhin.chambagri.fr/kitPublication/fileadmin/documents/Elevage/Apiculture/D%C3%A9coupe_du_couvain_male_-_experimentation_de_son_%C3%A9fficacit%C3%A9_-_CRA_2010.pdf Results summary: Kept mite levels substantially (25%) lower, but still needed additional control measures. Honey production did not suffer as a result of trapping. Unexpected result was control of swarming!
