Hmm, seems odd for the second post of a "newbie" to be about neonics, and to quote German studies....
Well that was helpful.ienen orientieren sich nach dem Sonnenkompass und entwickeln für ihre Flugrouten rund um den Bienenstock eine innere Landkarte. Im Experiment testeten die FU-Forscher die Wirkung der beiden nach ihren Angaben derzeit verbotenen Pestizide Imidacloprid und Clothianidin sowie des Pflanzenschutzmittels Thiacloprid: Sie trainierten eine Gruppe Bienen zunächst darauf, eine Futterstelle 400 Meter entfernt vom Bienenstock direkt anzufliegen. Danach summten die Tiere wieder zurück.
In the test situation, the navigation of the bee has two phases, the so-called vector flight and the so-called homing flight. In a third step, the test bees were administered a small amount of the pesticide in their feed. It turned out that their sense of direction during the homing phase was disturbed by the insecticide.
Uber brilliant! There is a direct correlation between dose and effect.Significantly fewer bees successfully returned to the hive, and overall, the flight paths were less direct.
The only reason that I am offended is that the article has proven what has been proven many times in the past: dont feed bees poison.I I don't see why people get so offended when we talk about something that can be harmful to bees.
