Summary
In order to study further details of the function of JH in adult honey bees, precocene II was applied to workers and queens. Corpora allata ultrastructure, JH and vitellogenin titer (worker bees) as well as egg-laying activity (queens) showed no specific changes after precocene treatment. Doses of 80 μg caused high mortality in workers while queens tolerated 200 μg.
