Primary Research Topic:
Ecology and biological control of Ambermarked birch leafminer (Profennusa thomsoni) by the parasitoid wasp, Lathrolestes luteolator

Project Description:

I investigated the ecology and biological control of Ambermarked birch leafminer (Profenusa thomsoni) by the parasitoid wasp, Lathrolestes luteolator. P. thomsoni was introduced in the early 1990’s to Anchorage, Alaska where it now causes severe damage birch. L. luteolator has effectively controlled P. thomsoni in other areas but does not appear to have been introduced to Alaska along with the leafminer. The primary aim of my project is to introduce L. luteolator to Alaska and establish a population that will eventually control P. thomsoni. Additionally I also investigated the ecological relationship between P. thomsoni, L. luteolator and birch, the distribution of P. thomsoni and two other related species in Alaska, the biogeography of P. thomsoni in North America. An additional component of my research was evaluating the species – host relationship of the Lathrolestes genus in North America parasitizing other leafmining sawflies. This work was part of a joint project between the US and Canadian Forest Services with fieldwork in Anchorage, Alaska.
