DOIAbstract
Classical biological control relies on the deliberate introduction of natural enemies to reduce pest populations below damage thresholds. Knowledge on key aspects of the behavior of antagonists and their population densities through time can be important to increase the efficiency of control programs. The woodwasp Sirex noctilio is a global threat to pine forests and biological control can be based, among other agents on two parasitoids, Ibalia leucospoides and Megarhyssa nortoni, with variable success. Currently no sensitive and standardized monitoring method exists for these control agents and little is known on their behavior, such as their vertical flight-distribution. Our aims were: firstly, assess the efficiency in capturing the paras...
