you can paint the baldness atribute on a map of it.. like your texture map. be worned you do have to have a good UV map of that model.. at least the part your doing. But your best bet for fur in just selected airas is to copy your bee. With the bee copy, delete the faces whare you will not want fur. Fur that copy. and shrink the geo a little or make it hiden.. the fur will come through the geo of the origanal if done right. Doing it like that also makes it render a little faster. Becouse its not salving for the hole body of geo..
