Pecan nut casebearer (Lepidoptera: Pyralidae) sex pheromone used to monitor phenology and estimate effective range of traps
Journal of Economic Entomology 90 (4), 983-987
Abstract: Sex pheromone traps for pecan nut casebearer; Acrobasis nuxvorella Neunzig, were deployed at densities of 1, 2, and 4 traps per tree in blocks of 9 trees or in single, isolated trees, replicated 4 times in an isolated, vegetatively propagated pecan orchard in western Texas to examine male moth activity. The phenology of overwintering generation pecan nut case-bearer male moth activity was consistent among the 6 treatments. Male moth capture per trap tended to decrease as traps per tree increased, but captures per tree were not significantly different among the 6 treatments, indicating an effective catch area of 1 tree for a trap. Catch differences were found among, trees within the 9-tree-blocks, with fewer moths caught in traps within the center tree and more captured in the southwestern tree, west tree column, and south tree row. Trap lines extending away from the orchard caught few moths. Pheromone-baited traps show merit in detecting moth phenology and may have application in assessing moth density for making pest management decisions.
