Two Questions First question> With Intrument insemenation how much semen should be used to effectively insemenate the queeen? Could someone give me the answer by way of cubic millimeters (mm)? I have been insemenating queens for a number of years now and have recently obtained a machine for measuring small amounts of liquid, I would like to know what the optimuim would be. I currently use about 7 to 12 drones depending on how effective I have been at scooping up the semen. Second Question> Here in New Zealand we control and effective resolve the problem of Nosema. We use a chemical called "Fumidil B", which is of couse a trade name for a chemical of similar sounds. I would like to know the effective way of despencing the chemical arround a commercial apiary. Could some of you reply as to the different methods that you use and possibly the best method in line of effeciency and effectiveness. ******************************************************** Jonathan KP Marshall of [log in to unmask] Proprietor of: Taranaki Honey Supplies & Taranaki Queen Breeders ********************************************************
