Abstract: Mark-recapture experiments were run from 2002 to 2004 to assess factors that influence capture of male gypsy moths, Lymantria dispar (L.), in traps baited with (+)-disparlure. Two plot designs were used. One was a center-release design: six and twelve traps were evenly spaced along two concentric circles with radii of 40 and 80 m, respectively, and moths were released at the center of the circles. The second was a center-trap design: males were released from 12 points around a single trap; i.e., at three distances in each of four cardinal directions. For the center-trap study, several combinations of release-to-trap distances were used (12.5, 25 & 50 m; 50, 100 & 150 m; 50, 150 & 250 m). Laboratory-reared males (NJSS strain) were marked with Day-Glo powder (and, if needed, Sharpie on forewing) and released on the day of emergence. For six replicates of the center-trap plot (all 50, 100 & 150 m), males were released on three consecutive days, but the trap was not put into place until just after the third day?s release.
