The first thing our adult female cat did when we brought in a new kitten was give him a slap to the face, she would be very wary around him at first and sometimes knock him down to discipline him if he did something she didn't approve of, we tried making them eat together, first in the same room but in opposite sides, then every day we'd put the food bowls a little bit closer, this way she got used to him in just a week or two, they're super best friends now and he even saved her from an aggressive stray cat a couple years ago.
It can be a little hard at first, but maybe if the kitten becomes friends with your male cat, the female will eventually come check him out?
