13.5 Starting the experiment

Before starting the experiment make sure that the temperatures are above 20°C, wind velocity is low and the sun shines most of the day. After a previous period with rainy days drones will fly for mating under less favourable conditions than after a period with fine weather. Also, drones will follow the queen dummies more intensely after some days of unfavourable weather. It is helpful to create a check list before starting for drone experiments in the field. The drone flight time is short and often the experimental drone site is far away from the lab.
