ae ) 
of the scale above 1 foot from the ground were found to be dead, while at 6 
inches from the ground little mortality was noted. The twice-stabbed lady- 
beetle (Chilocorus bivulnerus Muls.), which feeds on the scale, was fairly 
abundant in the plots, being noticeably more abundant at the bases of trees 
Where the scale was alive. No eges of the beetle were noted but 49 adults 
were counted on one tree within 10 feet of the ground. 
_Starvation resistance of gypsy moth larvae.--W. Le Baker, of the 
Melrose Highlands, Masse, field laboratory, started three trays, each con- 
taining 100 newly hatched gypsy moth larvae, in a screened insectary on May 
14 to obtain information on the length of time such larvae can live without 
food. In one tray moisture, in addition to that present in the air, was 
provided. In this tray the larvae lived an average of 10.9 days, while in 
the other two trays the average was 8.2 dayse These data differ consider- 
ably from those given by Forbush and Fernald in their book, The Gipsy Moth, 
published in 1896, They offered data showing that newly hatched larvae 
lived an average of 4.2 days in the absence of food, but these data were ob- 
tained by placing larvae in corked vials where conditions were doubtless more 
abnormal than in tthe tray experiments conducted by Mr. Bakere 
Further notes on satin moth perasites in Washington,=-In the last 
Monthly Letter of the Bureau reference was made to the recovery of two Euro- 
pean parasites, Apanteles solitarius Ratze and Meteorus versicolor Wesme, 
from the satin moth in the State of Washington, these parasites having been 
liberated there during the last few years from material forwarded from the 
Melrose Highlands laboratorys In May the laboratory received a very interest~ 
ing report from Randall Latta, of the Sumner, Wash.e, laboratory, regarding 
the abundance of Apanteles solitarius in satin moth infestations in that 
State. Mre Latta spent 4 days in May visiting satin moth infestation from 
Centralia to Bellingham and found the Apanteles present at every place where 
he stopped to make observations. The extent to which the parasite has mul» 
tiplied and spread, as indicated by this report, is quite'remarkable. Only 
one colony was liberated in Washington. It consisted of 13 males.and 244 
females and was put out at Kent on June 6, 1932, Bellingham is nearly 100 
miles north of Kent, air line, and Centralia is about 45 miles southwest. 
The following statexents taken from Mr. Lattats report indicate the abundance 
of Apanteles at some points visited: "At Kent satin moth larvae were not 
overly plentiful, buf Apanteles cocoons were plentiful, every crevice in the 
bark having one or more; at Longacres, 6 miles from Kent, willow trees were 
literally alive with caterpillars and the fence posts under the trees were 
so thickly covered that the wood was not visible, the masses on the fence 
‘posts being mostly webbed together and from 15 to 50 Apanteles cocoons being 
present in each mass;. at Sumner, about 12 miles from Kent, as high as 8 to 
10 or 15 cocoons could be found under one web in a crevice no larger than 
would hold my index finger; at Marysville, about 45 miles from Kent, 210 
cocoons were counted on the under side of a branch 6 feet long and 4 inches 
or less in diameter," ;
