（单词翻译）
-You catch it the moment I see it, put it into a container like this, which contains 15 milligram of so-called solution.The bees are fed one of two different solutions.
-We have c** which are fed with
pesticide1. We develop it in the circle solution and other creatures are not fed with pesticide. We compare them.
The bees have made many trips to the feeding station and that means they know how to fly in a straight line between here and the hive. They do this on autopilot, using what's known as their vitual memory.
-So when she is ready to take off, she will just fly back to the hive, using her victual memory. That's all what she will do, and she expects the hive in 500 meters in the northwest.
But today, Randolf is setting out to confuse the bees a bit. He's going to take them several hundred meters away from the place where they normally feed and then track their tents to get back to the hive.
-OK, we are at the release site now. So let's say this is the release site. The feeding station of us over there and this is the hive, in this direction. So let's say, this is the feeding station, this is the hive and they have learend to fly along this direction over 500 meters. Now, we release them here, which means they use their memory for the victual, and that means they fly along this
hood2. But if they arrive there, there is no hive. So the question is if the animal is released here, how do they find home and what is the effect of
pesticides3 on this behavior.
First, he releases a controlled bee that hasn't been
affected4 by the pesticide.
