White-marked tussock moth cause defoliation and contamination of blueberry fields, and can cause allergic responses in hand-pickers. Development of an integrated pest management program for this insect is required to minimize economic losses. Over two growing seasons, the development of cohorts of tussock moth was tracked, revealing two distinct generations and egg hatch occurring during early bloom and in mid-summer. These phenological events were predictable based on growing degree day timings, enabling improved timing of chemical controls. Trapping studies identified the optimal design and placement of pheromone traps, and showed that a single lure was effective throughout the season. Bioassays and field experiments with broad-spectrum and selective insecticides suggest that tussock moth can be effectively controlled using currently-registered insecticides. We conclude that crop infestation by this pest can be prevented through a combination of monitoring, use of a degree day model, and timely application of effective insecticides.
