Mating Behavior and Identification of Male-Produced Pheromone Components in Two Woodwasps, and , in China.

To protect vulnerable trees from native and invasive wood wasps, the mating behavior of these two woodwasp species ( and , respectively) and factors influencing this behavior were investigated in cages outdoors. Male-produced pheromones were identified in both woodwasp species. Compared with the native species the invasive species showed stronger mating ability, including mating frequency, time, and duration.
