SALEM, Ore. (AP) - Oregon state inspectors say they did not find any Asian gypsy moths in a 13.75 square mile target area in Portland, indicating that an aerial pesticide spraying program has worked.

The Capital Press reports (https://bit.ly/2dOHjip ) that the state Department of Agriculture oversaw three pesticide applications in the Forest Park and North Portland areas using Bacillus thuringiensis var. kurstaki, known as Btk.

Asian gypsy moths are a destructive crop pest and likely arrive on cargo ships from Russia, Korea, China and Japan.

None of the moths were found when officials checked 3,000 traps in Portland and 19,000 statewide. ODA pest program manager Clint Burfitt says in a news release that the agriculture department will do two more years of trapping but believes the spraying has succeeded for now.
