Our view: A banner day for bugs


There are several varieties of the bug.

One is the brown marmorated (for its marbleized shell). A native of the Far East, it has been in the United States for at least 15 years. It has since been found in more than 30 states, including New Hampshire and Massachusetts. This variety is especially damaging to crops — it will eat anything that fruits.

But University of New Hampshire entomologist Alan Eaton believes the culprit in this region is more likely another variety of stink bug, the Western conifer seed bug, which feasts on the seeds of fir and pine trees.

A native of the West Coast, the bug has moved east and even made the jump to Europe as an invasive species. It was first documented in New Hampshire in 1997, about the same time the other variety was identified in Pennsylvania.

If that’s not enough, it’s been a great season to be a yellow jacket. The bees were so plentiful at the Topsfield Fair last week that organizers were forced to put out sugar barrels to keep them away from people.

Eaton said this has been a bad year for the bug — or a good one, from their point of view — but he’s not sure why.

One factor may have been the unusually mild winter of 2011-12, followed by the early spring. The milder weather is easier on the bugs, as it is on us, and may have allowed more of the insects to survive and to reproduce multiple times.

We’ll take another mild winter at the risk of another bad year for bugs and hope that the boom year will be followed by a bust, as often happens in nature’s cycle.

Anyone remember the gypsy moth caterpillar infestation of the early ’80s?

The caterpillars chewed up 13 million acres of foliage from Maine through Maryland in 1981 before the population crashed.
