Determining Host-Parasitoid Linkages Between Sirex Noctilio And Sirex Nigricornis Through Molecular Techniques, Samantha Page

Honors Theses

The European woodwasp, Sirex noctilio, is a wood-boring insect native to Eurasia and North Africa, which was accidentally introduced across the Southern Hemisphere where it caused extensive economic damage to conifer plantations. Discovered ten years ago in North America, S. noctilio competes directly with Sirex nigricornis, a native congener, through shared resources in host trees. The two species also share a suite of six parasitoids, which utilize both native and non-native species of woodwasps as hosts. To study these interactions, it is common practice to fell trees and split logs from which siricid larvae and their parasitoids are collected. It ...
