Treatment

Reflow for from twenty-four to thirty-six hours soon after the middle of May. It may be necessary to reflow a second time. Destroy all caterpillars washed ashore while the water is on. In dry bogs, spray early in May with arsenate of lead.

Fire-Worm, Cranberry Worm, Or Black-Headed Cranberry Worm (Eudemis Vacciniana)

Small larva, green, black-headed, feeding upon the shoots and young leaves, drawing them together by silken threads; two broods.

Treatment

Flooding for two or three days when the worms come down to pupate. Arsenicals.

Fruit-Worm (Mineola Vaccinii)

Small caterpillar working in the fruits, eating out the insides.

Preventives

For bogs with abundant water, reflow for ten days immediately after picking. Let the foliage ripen, and then turn on water for winter. Draw off water early in April, and every third or fourth year hold it on until the middle of May. For dry bogs spray three times with arsenate of lead during July. Bury all screenings.

Yellow-Headed Cranberry-Worm (Acleris Minuta)

Stout, yellowish green, small caterpillar, with a yellow head, webbing up the leaves as it works.

Treatment

Hold the water late on the bog in spring to prevent egg-laying. Arsenicals from the middle of May till July 1.
