Acoustic Detection of Arthropod Infestation of Grape Roots: Scouting for Grape Root Borer (Lepidoptera: Sesiidae)

Behavioral response of grape root borer (Lepidoptera: Sesiidae) neonates to grape root volatiles.

Grape root borer, Vitacea polistiformis (Harris), is an oligophagous and potentially destructive pest of grape in commercial vineyards throughout much of the eastern United States. Larvae feed on vine roots, although little is known about their below-ground interactions with host plants. The behavioral response of groups of grape root borer neonates to stimuli from host and nonhost roots was ev...

Electroantennogram Responses of Both Sexes of Grape Root Borer (Lepidoptera: Sesiidae) to Synthetic Female Sex Pheromone

The effect of mating status and sex on antennal response to sex pheromone components was tested in the grape root borer, Vitacea polistiformis (Harris). The grape root borer pheromone is a 99:1 blend of (E,Z)-2,13-octadecadien-1-ol acetate (EZ) and (Z,Z)-3,13octadecadien-1-ol acetate (ZZ). Antennae of both virgin male and female moths exhibited similar doseÐresponse patterns, with a threshold d...

Applications and mechanisms of wax-based semiochemical dispenser technology for disruption of grape root borer mating.

Grape root borer, Vitacea polistiformis (Harris) (Lepidoptera: Sesiidae), is an important pest of cultivated grapes (Vitis spp.) in the eastern United States from Michigan to Florida. There are few registered insecticides for control of this pest, and their efficacy is limited. Pheromone-based mating disruption is a potential alternative to insecticides for management of V. polistiformis. Wax-b...

Grape Detection in Vineyards

Evaluation of pheromone-based management strategies for dogwood borer (Lepidoptera: Sesiidae) in commercial apple orchards.

The dogwood borer, Synanthedon scitula (Harris) (Lepidoptera: Sesiidae), is a serious wood-boring pest of apple in eastern North America. The recent identification of its sex pheromone and systematic documentation of the effect of a potent behavioral antagonist affords the opportunity to develop pheromone-based management strategies for this important pest. Here we evaluated the potential of ph...
