SATIN MOTH 
In some sections of the infested area in New England, particularly 
in Massachusetts, records obtained during .the summer of 1935 indicate that 
the satin moth is on the increase. Although no extensive areas of defoliation 
were noted, the insect was abundant enough to cause noticeable defoliation in 
29 towns widely scattered over the entire infested area in Massachusetts. 
For the most part, this defoliation was confined to a few trees. In Rhode 
Island noticeable defoliation was found on a few trees in one town. In New 
Hampshire some defoliation was noted in three towns scattered widely over the 
infested area, but it was confined to a few trees in each place. There were 
no records of this ■ insect *s being abundant enough in any town in Maine to 
cause noticeable defoliation, (A. F. Burgess, Bureau of Entomology and Plant 
Quarantine, U. S. D e A.) Note ,-- -A survey conducted in Oregon in July revealed 
the presence of the insect in Benton, Clackamas, Linn, Marion, Multnomah, 
Polk, Washington, and Yamhill Counties, No damage was being done, however, 
except near Gervais, Marion County, the site of the original infestation in 
Oregon. P. T. Webber, of the Bureau of Entomology and Plant Quarantine, re- 
ported that in Washington infestations in residential sections outnumber 
those in woodlands. The principal woodland infestations lie between Everett, 
Snohomish County, and Bel'iingham, Whatcom County, where willows seem to be 
the favored food plant. Other woodland infestations of an acre or more have 
developed to complete defoliations in Pierce and Cowlitz Counties, Mr* 
Webber says: "Five species of parasites of European origin, namely, Apanteles 
solitarius (Ratz.), Meteorus versicolor Wesm. , Eupteromalus nidulans ("horn. ), 
Rogas unicolor Wesm., and C ompsilura concinnata Meig. were liberated (in 
western Washington) and all but R. unicolor were recovered. Only one species, 
A. solitarius , has established itself so well that its effectiveness is 
now apparent over the entire territory. Parasitization by this species in 
the localities of host abundance will reach 11, S percent, increasing in its 
effectiveness in localities of host scarcity where it attained a maximum of 
32. S percent." 
CANKERWORMS 
Cankerworms occurred in outbreak numbers over much of the Northeastern 
States, with a severe infestation centering in southeastern New York and New 
Jersey and extending into Maine. Scattered infestations occurred in north- 
western Ohio, Illinois, western North Carolina, southeastern Wisconsin, 
southern Iowa, Missouri, much of Kansas, and the Sacramento Valley of Cali- 
fornia. Severe defoliation of forest, shade, and fruit trees was reported. 
The fall species, Alsophila pome tar ia Harr. , was most frequently named as 
causing the injury, although the spring species was commonly represented. A 
report of A. pome tar ia from Salt Lake County, Utah, gave a new State record 
for the specios, 
FOREST TENT CATERPILLAR 
A small isolated infestation of the forest tent caterpillar was re- 
ported from the coast counties of Mississippi and across the State line in 
Washington and Saint Tammany Parishes, La., the last of April and the first 
of May. A more extensive infestation developed later in the season in south- 
eastern New York, and in Connecticut, Massachusetts, Vermont, New Hampshire,
