Interpretive Summary:

Technical Abstract: Populations of male pickleworm, Diaphania nitidalis (Stoll), moths were monitored using different types of traps baited with virgin female moths or synthetic sex pheromone lures. Modified box traps and wire-cone traps were highly effective when baited with either synthetic lures or virgin females. Unitraps baited with virgin females were less effective than box or wire-cone traps, and unitraps were ineffective when baited with synthetic pheromone lures. Nylon-cone traps were much less effective than wire-cone or box traps. Pherocon 1C sticky traps did not work with any lure. In an initial attempt at a multi-state monitoring program for forecasting pickleworm populations, a network of wire-cone traps was setup at 14 locations in NC, SC, GA, and FL in 1997. Although problems were encountered with the pheromone formulation in 1997, important parameters for establishing a successful pickleworm forecasting system were determined, including trends in local pickleworm populations. Also, trap captures could be correlated to larval infestations in the field. Formulation problems with the pheromone lures have been solved, and a second attempt at establishing a regional pickleworm forecasting system will be made in 1998.
