Hello All,
*Larger cell size reduces varroa reproduction (ABJ vol. 141 no. 12 pg. 895)
While searching for the reason varroa mites do not reproduce in worker brood of cerana researchers found that mellifera worker brood raised in mellifera drone cells had only 17% varroa reproduction while mellifera worker brood raised in mellifera worker cells had 100% varroa reproduction. ( ABJ vol. 141 no. 12 pg. 895)
Could there be a larger cell size which would control varroa if mellifera could be upsized to the size? Hmmm.
Sincerely,
Bob Harrison
