Community Pest Management - A Systems Approach

Jeff B. Welch, Quinton Hornsby, Dr. Theresa Singer and Dr. Donald R. Johnson


 
ABSTRACT

Pest management communities in Arkansas were initially designed to manage the bollworm, Helicoverpa zea Boddie, over a wide geographical area. However, these communities have evolved to manage other pests such as the budworm, Heliothis virescens, and the boll weevil, Anthonomus grandis Boheman. A systems approach to manage Heliothine spp. involves field population determination through scouting, species determination through moth catch results, and resistance monitoring of the budworm moth using insecticide treated glass vials. Treatment decisions are based on field populations of eggs and small larvae. Timing of community or quadrant sprays are designed to commence with hatchout of the majority of the eggs. Recommendations of treatments are made using species composition and budworm resistance monitoring data. Implementation of treatments are scheduled for a 72 hour period, and evaluation of efficacy for the following 72 hour period.
