Grape Root Borer*Volunteer Monitoring Network trapping data now available

The Grape Root Borer*Volunteer Monitoring Network (GRB*VMN) has been up and running for a month, but the first, substantial trap captures occurred last week. The network consists of 10 locations in 7 North Carolina counties. Trap captures from these sites will be available here through the end of October, when the grape root borer flight is expected to end.

2011 GRB*VMN sites. Sites are only identified to the county level and assigned a number for record keeping purposes when there are multiple sites per county.

Monitoring locations and trapping data are listed below, from east to west:

Jones County 1

Rowan County 1

Rowan County 2

Davie County 1

Yadkin County 1

Surry County 1

Surry County 2

Surry County 3

Wilkes County 1

Haywood County 1

The highest number of trap captures is currently in Davie County with a few other locations catching a few moths. It is interesting that our flight appears to be occurring so late in the year, since reports of moth captures begin in July last year. We are monitoring the grape root borer flight in North Carolina to better understand when and where our highest populations occur. This information is important when making grape root borer management decisions, in particular whether or not to use currently labeled pesticides, which must be used either 30 days before harvest or after harvest. If you are interested in monitoring grape root borer yourself, see here for more information.
