EVALUATION OF BLUE-GREEN SHARPSHOOTER FLIGHT HEIGHT

• Author(s): Weber, Ed;
• Abstract: Flight heights of blue-green sharpshooters between vineyards and riparian zones were monitored at eleven sites in Napa Valley in 2004 using pole towers to position yellow sticky cards up to 24 feet. At 10 of the towers, nearly 90% of catches from March-September were made at 15 feet or lower. At one tower, however, a large number of BGSS were caught in the upper traps in early March. This towers proximity to a Coast Live Oak (Quercus agrifolia) tree suggests that BGSS may reside at higher elevations in trees at some times of year.
