Fungus Controling Emerald Ash Borer

A recent study shows that male emerald ash borers infected with a deadly fungus readily transmit the fungus when mating, opening doors for future biological control efforts.

Canadian scientists have figured out how to hit the tree-killing emerald ash borer (Agrilus planipennis) where it really hurts by employing a fatal fungus that turns mating into a way of decreasing, not increasing, its numbers. Male emerald ash borers infected with the fungus on contact inside a small chamber readily transmit it females during mating, with both dying thereafter, according to research published in the Journal of Economic Entomology.
