Great to welcome Dan Bray to Bielefeld yesterday, a chemical ecologist from Keele University (UK) – and currently in Kiel (Germany) on a DAAD fellowship – who gave the first Behaviour & Evolution seminar of the new semester, on “Understanding and exploiting chemical ecology for disease control”. Dan talked about a long-term project he has been working on to attempt to control the sand fly vector of leishmaniasis in Brazil, taking advantage of natural sand fly behaviour by using artificial sex pheromone lures. You can follow him @DrDanMonkey. Dan and I are also former colleagues from our time together as PhD students at the University of Liverpool, so it was great to catch up. Cheers Dan!
