Commercial Traps for the Gypsy Moth, 1981

Abstract

Abstract Commercially available traps are being marketed by at least 2 companies for use in an “Integrated pest management program” for gypsy moth control. Two examples of each of 3 types of traps were deployed in a residential neighborhood in State College, PA. Moth capture data obtained during the peak adult flight period (Jul 10-July 21, i.e., 24 traps-days per trap type) were used to assess the relative efficiency of the traps. Traps were at a density of 1 per 9375 ft2; manufacturers’ recommendations are 1 trap/10,000 ft . A hypergeometric design was used, in which each trap was placed for 24 hr in each of the 6 positions exactly once in each of the 2 successive 6-day periods. The 2 Health-Chem traps are essentially 2 qt cardboard milk cartons, with a laminated Luretape wick containing racemic disparlure and an insecticidal strip containing 2-(1-Methylethoxy) phenol methyl carbamate, within the trap. Two ports, each 1“x3/8” and protected by a hood, are cut in each side of the trap. The Lure ‘n Kill homeowner trap is green, the Hereon community use trap is orange; otherwise the traps are identifical. The Bag-A-Bug gypsy moth trap has a clear plastic hood on a green container (volume cal-1/3 qt); six 15/16“x3/8” entrance ports are located under the hood. Hollow fibres dispense the (t)-disparlure bait; 2,2-dichlorovinyl dimethyl phosphate is the active ingredient in the toxic insect strip for killing moths which enter the trap.
