The Department of Plant and Environmental Protection Sciences, or PEPS, brings together experts in several fields (plant pathology, entomology, weed science, integrated pest management, to name a few) that are dedicated to protecting both crops and the environment. The department's purpose is to develop and disseminate environmentally friendly plant protection principles and practices for the tropics and subtropics, protect the structural integrity of buildings from destructive pests, provide strong programs in fundamental science and provide a quality education in related areas.

Studies in Plant and Environmental Protection Sciences at the University of Hawaii are strengthened by cooperative relationships with the following units:

  • Ecology, Evolution, and Conservation Biology Program
  • Bernice Pauahi Bishop Museum
  • Agricultural Research Service of the United States Department of Agriculture (USDA-ARS)
  • Animal and Plant Health Inspection Service of the United States Department of Agriculture (USDA-APHIS)
  • Hawaii Department of Agriculture, and Hawaii Department of Land and Natural Resources

Program highlights

  • Environmental protection
  • Invasive species
  • Biodiversity conservation
  • Genetic engineering for pest & disease resistance
  • Biological control of pests using natural enemies
  • Agricultural & urban pest management
  • Sustainable pest management

Careers for PEPS graduates

  • Science education (e.g. high schools, media)
  • Agricultural production (farming, crop protection advising)
  • Government agencies (EPA, FDA, USDA-APHIS, FBI, HPD, HDOA, HDOH, FWS, NPS)
  • Consulting (private and business)
  • Environmental management (EPA, HDoH, DLNR, FWS, NPS)
  • Business (fertilizer and pesticide sales)
  • Industrial research (pesticide development, genetic engineering, seed technology companies)
  • Management with private industry (e.g. pesticide development)
  • Service-oriented entomological services (e.g. urban pest control)
  • Teaching, research, and extension at universities and colleges
