Hi Peter,



I agree but it’s the other way around. Our findings contradict the previous studies. There is plenty of evidence for 2-heptanone being present in many situations, in insects, mammals, plants - even in cheese and what exactly it does will probably differ from case to case. In honeybees, we examined the effect of 2-heptanone at different concentrations on the behaviour of the bees. Of course, any experimenter may be wrong, but we could see no evidence whatsoever of 2-heptanone causing any aggressive or alarm behaviour in honeybees. 



Best regards,



Max
