Research Description

My dissertation focuses on the Australian Light Brown Apple Moth, Epiphyas postvittana, and its natural enemies in California. Since its discovery and initial spread in California in 2007, this invasive moth has been in decline, contrary to the trend for most invasive species. Typically, invasive species are released from natural enemies, such as parasites, permitting successful population growth in their new regions. To understand this phenomenon, I study interactions between nutritional and defensive qualities of host plants and the resident parasitoid wasps and parasites that attack this moth in California.


1) Estimate the degree of variation in parasitism by parasitoid wasps of egg and larval stages of the Light Brown Apple Moth on different plant species in the field and the laboratory.

2) Determine the prevalence of infection of Light Brown Apple Moth larvae by a microsporidian parasite in field populations and its pathology.

3) Investigate the role of different host plants and nutrition on the pathology of the microsporidian parasite in Light Brown Apple Moth larvae.
