Abstract：In colonies，virgin queens naturally mate with several males，forming subfamilies． In order to find differences
in lifespan between subfamilies，an experiment was conducted with Apis mellifera L． We collected 270 emerging workers
from a naturally mated queen colony，holding them separately in a small box with a comb with sufficient food，and picked
out and counted the naturally dead insects every day． We determined genotypes of marker workers based on 3
microsatellite primers and identified the patrilines． Survival curves of the different subfamilies were drawn for survival
analysis． The results indicate that the experimental colony was made up of 12 subfamilies，with two of these having
significant survival differences from the other subfamilies (P ＜ 0. 05) ．
