Pecan nut casebearer pheromone monitoring and degree-day model validation across the pecan belt Conference Paper uri icon

abstract

  • Pecan nut casebearer (PNC) was monitored at thirty-seven locations in eight states across the pecan belt with sticky traps baited with gray butyl rubber caps treated with 100 micrograms (μg) E(8),Z(11)-hexadecadienal. The pheromone proved to be an effective lure at all locations. Longevity of lure effectiveness exceeded 8 weeks. Data from traps proved an effective means for developing emergence curves for adult male moths and estimating percent emergence and adult activity. In locations where available weather data permitted phenological predictions by the Texas PNC degree-day model, pheromone monitoring proved effective in model validation, improvement of model predictions and in continued model development.
