Elisabeth is on a roll with two new publications from her thesis!
In a study published in Canadian Entomologist, she found during multiple 24 hour observational studies that swede midge emerge as adults in the first few hours after dawn and are ready to mate.
She has also found that both natural and the cheaper racemic pheromone blends can disorient male swede midge and prevent them from mating.
Here are the publications:
Hodgdon, E. A., R. H. Hallett, K. F. Wallin, C. A. Stratton, and Y. H. Chen. In Press. Racemic pheromone blends disrupt mate location in the invasive swede midge, Contarinia nasturtii. https://doi.org/10.1007/s10886-019-01078-0
