INSECT PEST SURVEY BULLETIN

OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES 
FOR MARCH, 1331. 
We wish to call the attention of our readers to the reports on insect 
conditions in tro-oical American countries which we are introducing in this 
volume of the Survey Bulletin. In the first number of this volume insect 
conditions in Forto Rico were reported "by M. D. Leonard, and Marston Bates 
gave a report on insect pests of Honduras and Guatemala. In this number v:e 
have reports from Forto Rico, Honduras, Guatemala, and Mexico. The cosmo- 
politan aspect that entomology has assumed makes these contri cations extreme- 
ly valuable. 
The Hessian fly is reported as comparatively scarce in Virginia and 
Ohio- On the other hand in western and southeastern Iowa there appears to he 
a very heavy infestation. 
Indications of -possible chinch hug trouble have been observed in c entral 
Illinois, central Missouri, and southeastern Kansas. 
The first observation of eggs of the corn ear worm was reported from 
Galveston County, Texas, on February 10. 
Local damage to "oeas, vetch, and alfalfa by the pea aphid was reported 
from the Salt River Valley of Arizona and the Willamette Valley of Oregon. 
Eggs of fruit aphids appear to be unusually scarce throughout the en- 
tire eastern part of the United States, westward to Kansas. 
Throughout the Middle Atlantic and South Atlantic States the codling- 
moth is abnormally abundant. The first observation of pupation was reported 
March 30 from South Carolina. 
Throughout the New England and Middle Atlantic States the eastern tent 
caterpillar is not numerous. On the other hand, reports of unusual numbers 
of this insect have been received from Arkansas and Texas. By the 22d of 
March caterpillars were about foil grown in the vicinity of College Station, 
Tex., and eggs were hatching on March 12 at Fayettevilie, Ark. 
The San Jose scale is apparently increasing in the Middle Atlantic 
States and the East Central States. A very high winter survival is reported 
from central Illinois running from 50 to 73 per cent, while in this district 
a normal survival is only from 25 to 30 per cent. Survival was also high in 
the Great Basin section. 
The European red mite is reported as unusually abundant in New England 
and very scarce throughout the Middle Atlantic States.
