Effect of Two Bark Beetle-Vectored Fungi on the On-Host Search and Oviposition Behavior of the Introduced Woodwasp Sirex noctilio (Hymenoptera: Siricidae) on Pinus sylvestris Trees and Logs

Abstract

Sirex noctilio’s fungal symbiont, Amylostereum areolatum, is required for its offspring’s development. The symbiont is a weak competitor with bark beetle-vectored fungi so it would be beneficial to the woodwasp if it avoided ovipositing in substrate colonized by these competitors. The response of S. noctilio to the presence of two beetle-vectored fungi… (More)
