Seasonal Changes in Adult Longevity and Pupal Weight of the Nantucket Pine Tip Moth (Lepidoptera: Tortricidae) with Implications for Interpreting Pheromone Trap Catch

Overwintering and Seasonal Patterns of Feeding and Reproduction inPhyllotreta cruciferae(Coleoptera: Chrysomelidae) in the Northeastern United States

“…4). The physiological state of insects has been observed previously to change trap catch, e.g., the apple maggot ßy, Rhagoletis pomonella Walsh (Rull and Prokopy 2000) and the pine tip moth, Rhyacionia frustrana Comstock (Asaro and Berisford 2001). While counts of ßea beetles on yellow sticky traps may not correlate well with the absolute population of beetles in the Þeld (Andersen et al 2005), such trap catches seem to correspond to relative densities of beetles likely to engage in feeding and therefore may be good predictors of potential feeding injury to the crop.…”

Efficacy of Wing Versus Delta Traps for Predicting Infestation Levels of Four Generations of the Nantucket Pine Tip Moth (Lepidoptera: Tortricidae) in the Southern United States

“…Wing traps are open on all sides The quantity of tip moths caught per trap per day was always signiÞcantly greater during the spring emergence than subsequent emergence periods in this and an earlier study (Asaro and Berisford 2001a), even when population densities across generations were equal. Asaro and Berisford (2001b) demonstrated that adult male tip moth life span is signiÞcantly shorter during hot weather and showed how this might inßu-ence daily trap catch, although other explanations were considered. The quantity and ratio of pheromone components was shown to be stable between R. frustrana generations (Asaro et al 2001).…”

Irrigation and Fertilization Effects on Nantucket Pine Tip Moth (Lepidoptera: Tortricidae) Damage Levels and Pupal Weight in an Intensively-Managed Pine Plantation2

“…A comprehensive study by Asaro and Berisford (2001) found that female pupal weights ranged from 7 to 10 mg in the absence of fertilizer in the field. Pupal weight is a function of food quality and quantity, and provides an indication of potential adult fecundity and fitness (Miller 1957, Tisdale andSappington 2001).…”
