The Wisconsin Department of Natural Resources reports it is ending an aerial pesticide spraying program for about 50 eastern counties. The effort had been aimed at slowing the spread of the leaf-eating gypsy moth. The D-N-R says it was receiving fewer requests from local governments as private-sector alternatives have been developed. It seems to have worked, though. A 2016 report noted the national program had slowed the moth’s spread by more than 60 percent, reducing the losses on more than 125-million acres over a 16-year period.
