Confusion Sexuelle

Confusion Sexuelle – French term for biotic control through the use of hormones.
Several insects in the vineyard (French: vers de grapes) eat off the grape vine, the grapes and the leaves.
Through the use of sexual fragrances: pheromones, the males get confused.
(to them it seems that there are fertile female insects throughout the vineyard)
Because of that the reproduction stops and the disease is controlled.
