This is a short video about how the grape farmers stop the rot caused by two particular butterflies. They attach small brown plastic pods to the wires which support the vines, inside of which is the sexual hormones of the female butterflies. The emission of the hormones confuses the male butterflies and so they can’t find the eggs to fertilise! I thought that was so clever when it was explained to me by Isabelle Corbeaux of Champagne Pierre Deville and Veronique Lallement of Champagne Lallement, two lovely French ladies who are part of my English class here in Verzy.
You can see what I’m talking about in this video below.
