In 2003 and 2004, spray trials were performed in a vineyard (Concord grapes) that has a history of consistently high populations of grape berry moth (GBM), Endopiza viteana (Clemens) (Lepidoptera: Tortricidae). Materials tested were Intrepid 2F (methoxyfenozide), SpinTor 2C (spinosad), and two rates of Dipel 4L (Bacillus thuringiensis). Sprays were applied every 15-17 d in 2003 (starting 8 July), and every 14 d in 2004 (starting 11 June). Grapes were harvested in mid-September and evaluated for GBM injury. In 2003 Intrepid and SpinTor had significantly fewer injured berries compared with the control. 2004 injury data will be reported.

Grape root borer (GRB), Vitacea polistiformes (Harris) (Lepidoptera: Sesiidae) has not been a major pest in Virginia, but is expected to become more prominent as grape-growing expands. In 2003 and 2004, pheromone traps were installed in several Virginia vineyards to monitor GRB flight data and severity. Late summer sampling of vines for GRB larvae and cocoons indicate that GRB is becoming widespread in Virginia vineyards.
