Vine Mealybug Maps

Beginning in 2012, The Ag Commissioner's Office conducted an enhanced vine mealybug trapping program of 25 traps per square mile, well above the previous regimen of seven traps per square mile.  By analyzing the number of males found in each of the traps, staff is able to detect new areas of infestation as well as track reductions in population.
