Research

My research interests are integrated pest management and development and validation of biorational technologies for key horticultural pests on fruits and vegetables.  My research focus is on learning about the mechanisms involved in host plant-pest and pest-pest interactions, and field- and landscape-scale insect ecology and pest management.

Current Graduate Students in my Lab:

Andrew Tebeau, PhD, "European earwig in peach orchards of northren Utah: life history, crop injury, and effects of orchard management and habitat manipulation upon population dynamics"

Bonnie Bunn, MS, "Landscape-scale onion thrips population ecology"

Extension

I serve as the Utah Extension Integrated Pest Management (IPM) Coordinator. This program aims to increase the implementation of IPM on Utah lands (agricultural, urban, range, and forested) through demonstration and education. The Utah Extension IPM program is an interdisciplinary collaboration that involves faculty and staff from across the state.  Ms. Marion Murray, IPM Project Leader, is the key professional staff person who manages the program.

Currently Funded Extension Projects: 

"Utah Extension integrated pest management program", USDA NIFA EIPM Coordination Program, 2010-2013 (D. Alston, PI; M. Murray)

"Western region small farm-IPM working group", USDA NIFA EIPM Support Program, 2010-13 (T. Grasswitz, PI; numerous co-PIs)

"Pests of tre West: first-detector program for small-scale farmers", USDA APHIS, 2010-12 (T. Grasswitz, PI; numerous co-PIs)

"Development of IPM outreach materials for Utah and Colorado tree fruit growers",  Western IPM Center (USDA NIFA), 2010-11 (M. Murray, PI; D. Alston, H. Larsen)

"Survey to assess IPM implementation in Utah vegetable crops", Western IPM Center (USDA NIFA), 2011-12 (M. Murray, PI; D. Alston, D. Drost)

Teaching

Teach 5 lectures in Applied Entomology (Biol 4500) - Spring semester
