Research Description

Long-Term Research Goals

1) Incorporate biological control, polyculture and strategic use of the surrounding ecosystem into both productive and sustainable aquaculture practice.

2) Restore ecosystems undergoing species invasions or anthropogenically induced community changes

Dissertation Research

Species invasions, range expansions, and fluctuations in abundance, are some of the consequences and causes of environmental change. My dissertation examines why many invasive species increase in abundance and have substantial negative impacts in their new region while other invasive species decline and lack significant negative impacts. Contrary to the trend for most invasive species, the invasive Light Brown Apple Moth has been in decline since its initial spread in California in 2007. My work focuses on the multitrophic interactions and resident natural enemies involved in the decline of this moth in California and provides a unique opportunity to use this knowledge to inform control efforts for other invasive or nuisance species.

Objectives:

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

2) Characterize the novel microsporidian pathogen, Nosema fumiferanae-like isolate, and its pathology in the Light Brown Apple Moth

3) Determine the occurrence and load of N. fumiferanae; in field populations of the Light Brown Apple Moth using qPCR.

4) Investigate the role of low humidity, and different host plants and nutrition on the pathology of N. fumiferanae in Light Brown Apple Moth larvae.
