Development of a Pheromone-Based Monitoring System for Western Hemlock Looper (Lepidoptera: Geometridae): Effect of Pheromone Dose, Lure Age, and Trap Type

Uso de semioquímicos en el control de plagas. Estudios básicos y de aplicación

“…And Jactel and coworkers (2006) found an asymptotic increase response of catches of pine processionary moth (Thaumetopoea pytiocampa Denis & Schiffermüller) according to increasing doses of its pheromone from 0.5 to 20 mg, with 95% of maximum catch obtained with the 10-mg dosage. This asymptotic pattern has also been observed in other Lepidoptera species (Evenden et al, 1995;Knutson et al, 1998;Rao & Subbaratnam, 1998).…”

“…Para el trimedlure, no se observó un efecto de saturación con altas dosis, si no que a partir de una emisión de 2,4 mg día -1 , cantidades mayores de trimedlure no capturaban significativamente más moscas. Por lo tanto, en este caso se obtiene una respuesta de tipo asintótico, que también ha sido observada en algunas especies de lepidópteros (Evenden et al, 1995;Knutson et al, 1998;Rao y Subbaratnam, 1998;Jactel et al, 2006).…”

Atração de machos da lagarta-das-fruteiras Argyrotaenia sphaleropa (Meyrick) (Lepidoptera: Tortricidae) aos componentes do feromônio sexual sintético na cultura do caquizeiro

“…Enquanto alguns respondem efetivamente a doses relativamente baixas do feromônio sexual (Anshelevich et al 1993, Evenden et al 1995, Han et al 2001, outras necessitam de doses mais elevadas para monitoramento satisfatórios (Gries et al 1994, Zilahi-Balog et al 1995. Além disso, alguns insetos respondem efetivamente a ampla variação na dose do feromônio (Kehat et al 1994, Millar et al 2002, Badji et al 2003.…”

A novel approach to the assessment of fruit damage caused by Carposina sasakii (Lepidoptera: Carposinidae) using pheromone trap catches in Korean orchards

“…Other factors that affect the fitting ability of the model would be errors in estimating the parameters of sub-models. Also, the pheromone trap itself can give variations since various factors affect the ability of pheromone baited traps, including dose, ratio, and release rate of the pheromone blend (Anshelevich et al 1993;Evenden et al 1995), lure longevity, the effective range of pheromone, trap type, trap density (Evenden et al 1995;Knutson et al 1998), and the effect of weather on trapcatch (Knight and Croft 1987). The total number of fruits that can be variable yearly in the orchard may be another source for the model discrepancy, because we have applied constant numbers of fruits per unit area.…”
