Abstract:Under Maine conditions a number of species of climbing cutworms attack the blueberry in the early spring. During seasons of unusual abundance they cause severe crop losses by destroying the swelling fruit buds.
Syneda alleni, unlike the common forms, appears in the larval stage in midsummer. While the species was described in 1877 the writer has found no economic record concerning it nor any previous account of its seasonal history or immature stages.
A very severe outbreak of looping worms occurred in certain Maine blueberry fields in 1927. The outbreak reached its height in midsummer just prior to picking time. Leaves, green and ripe berries, and even the bark were eaten.
During the following June (1928) moths of the species, Syneda alleni, appeared by the millions in the fields which had been infested by the loopers the previous summer. Eggs were obtained on June 28 and larvae on July 4. Because of their slender appearance, looping movement, diurnal habit, and extreme activity, the larvae resemble the geometers quite closely.
Spraying with arsenate of lead at the rate of one and one-half pounds in 50 gallons of water gave good control.
Fermenting bait composed of syrup, water, yeast and honey gave an average catch of about 200 moths per pan.
