My plan is to have this “survey” as a separate paper. So sampling a lot of colonies (more than 10) will be best – the more the better (always!). You can do 20 drones per colony and take note how many of the drones have “envelope around the seminal vesicles – whether one or both or no envelop. You don’t have to weigh mucus glands. This is all about seminal vesicles of Apis florea this time and also do a culture to find out what causing that “envelop”.
