GYPSY MOTH 
Tho hatch' of egg clusters of the gypoy moth- "’an much more pronounced than it 
was in 193S. Egg clusters collected and observations : made in the field over quite 
an extended area showed a good hatch in most localities^ Very little winterkill 
was noted and a high percentage of hatch was, py rent in many poet ions of tho in- 
fer tod area. Hatching was late and spring mortality low in 1939* 
In Maine there gas a considerable increase in defoliation in 1939* an in- 
crease of about 60 percent over that in 1538, the total being, greater than in any 
other previous year. In Hew Hampshire there was an increase of approximately 
100,000 acres, all gradations of defoliation showing a, marked increase. In Ver- 
mont a gro-t increase was roted, more defoliation being recorded in -1939 than the 
total recorded for the la r, t 15 y°ars (1925-3-9* inclusive), In Massachusetts there 
was a slieiht decrease in defoliation as .compared with that recorded in 1938* In 
some sections a marked increase was noted, especially in Plymouth,' Norfolk, and 
Bristol Counties, with a slight increase in Dukes County,' There was a slight 
decrea-o in Worcester, Barnstable, rod Euanklin Counties , a; id a large de error e 
in Sc-ex, Middlesex, Hampden, and Hampshire G ount i s , There was over a 50— percent 
decrease in defoliation in the section between the Connecticut River and the 
bax 1 ior zone. In Rhode Island there was a big decrease in defoliation recorded, 
In Connecticut there was a marked increase in defoliation in 1939 over that 
recorded in 1938. (J. N. Summers., Bureau of "Entomology and Plant Quarantine,

BROWN-TAIL MOTH 
. During the summer of 1939 there were not many reports of defoliation by 
this insect, although in some sections’ of southern New Hampshire a considerable 
amount of complete defoliation was noted. According to records received from 
Maine, New Hampshire, and Massachusetts, tho total number of brown-tail moth web s 
cut by Strto or local crows, during the '-inter of 1938-39 was considerably greater 
than tho tot a], recorded during 1937-38. In Maine the number increased from ll6,00f 
in 1937-38 to 574,000 in 1538-39. This was due partly to an. increase in infesta- 
tion ana partly to an increase in the number of men employed on the work. With

SATIN MOTH 
Most of tho defoliation noted in the Now England area during 1939 was. con- 
fined to single or groups of poplar trees. In Maine the infestation was general 
but light in most localities. In N- w Harms hi re feeding "’as light, except in a few 
localities. In V- rnont and Massachusetts the f eedin~ was light; rand in Connecti- 
cut only a small amount of noticeable feeding was rioted, although in 1 locality 
a group of 100 large roadside poplar trees wore affected, (j, N, Summers, Bureau
