Abstract
Queens were inseminated with 1, 2, 4 or 8 mrn3 of semen, and either held, each with 250 workers, in an incubator at 34°C, or caged without workers in queenless colonies. In the first 4 h the amount of semen injected and the presence or absence of workers had little, if any, effect on the rate of entrl of spermatozoa into the spermatheca, which was 200--300 thousand/h. In queens injected with 1 and 2 mm of semen, the process of entry had largely ended after 4-8 h, but in queens injected with 8 mm3 it continued, slowly, up to at least 40 h. The presence or absence of workers had little or no influence on the final number of spermatozoa in the spermatheca when 1 or 2 mm3 of semen were injected, but it clearly increased the final number when 4 or 8 mm3 were injected.
