General Areas of Interest:

banner

Specific interests include:

  • I enjoy being an integral part of interdisciplinary team(s) developing and assisting growers to transition to well-balanced and holistic Integrated Fruit Crop Pest Management and Organic programs that are economical, environmentally sound and sustainable. Part of this enjoyment comes from working with growers, extension personnel, the marketing and processing industry and researchers at the local, regional, and national levels.
  • Developing, validating and implementing fruit insect sampling and degree-day decision-making protocols.
  • Development and implementation of alternative pest control measures: mating disruption, Bt against lepidoptera pests, codling moth granulosis virus, mass tapping against grape root borers and green June beetles, baited perimeter trap trees against plum curculio, nematodes against sesiids and plum curculio, releasing predatory mites, Surround particle film against Japanese beetle and plum curculio, and spot sprays versus whole planting spray programs.
  • Interest in introducing natural enemies or pathogens to suppress the newly introduced Japanese beetle in Arkansas.
  • I also take advantage of opportunities to contribute to the advancement of international fruit IPM programs: Republic of Yemen in 1990; India in 1999; Armenia in 2002-2003; and blackberries in China in 2007.
