Gypsy moth population on the rise
MADISON, Wis. (AP) — The state reports a 32 percent increase in gypsy moths trapped in Wisconsin this year and that may mean more aerial spraying next year.
The state Department of Agriculture, Trade and Consumer Protection says more than 385,500 male gypsy moths were caught in 2008, surpassing last year’s total of about 293,000. About 30,000 traps were set in 52 counties this summer as part of the agency’s efforts to slow the moths’ spread.
Trapping data help determine potential sites for egg mass surveys and next year’s aerial spray treatments.
Gypsy moth caterpillars feed on many species of trees and shrubs, especially oaks, and can cause defoliation when feeding in large numbers.
