in the tomato fruit, causing it to develop a disagreeable flavor. The 
adults are somewhat gregarious; a relatively light infestation may 
destroy a crop. 
BEAITS 
MEXICAN BEAN BEETLE ( Bpilachna corruuta Muls.) 
Maine. K. F. Howard (February 28): In a letter dated October 27, 1934, J. E, 
Hawkins gives Milo, Piscataquis County, as a record of the spread of the 
Mexican bean beetle. 
Ohio. N. F. Howard (February 21): The results of examining beetles in 
hibernation at Columbus indicate that the survival will be very much 
lower than during the preceding two years and it may approach the low 
point reached several years ago. 
Hew Mexico. R. L. Wallis (February 29): At present the survival of the 
Mexican bean beetle in the Estancia Valley is higher than for the past 
two years. Examination of beetles in hibernation cages February 18 
shows 55.17 percent of the beetles still alive. Counts showed 26,08 
percent at the same time in 1934, 24.08 percent in 1933, and 78.59 per- 
cent in 1932. 
PSAS 
PEA APHID ( Illinoia rdai Kalt. ) 
California. E. E. Campbell (February 21): All pea districts from Imperial 
to Salinas show some infestation, but in only a few fields is it heavy 
enough to cause damage. 
SEED CORN MAGGOT ( Hylemyia cilicrura Eond.) 
South Carolina. C. 0. Bare (January 8): The seed corn maggot was found 
doing considerable damage to garden peas at the Charleston Truck Experi- 
ment Station. The peas had been planted at a rather shallow depth in 
land containing decaying organic matter. In an approximately average 
situation in the field, a count showed 80 of 150 young plants, or 53 
percent, destroyed by maggots in the cotyledons. 
CABBAGE 
DIAMOND- BACK MOTH ( Plutella .aaculi-;en.iis Curt.) 
Virginia. H. G. Walker (February 25): Collection of material at Norfolk 
from several fields of kale and collards which were severely damaged 
last fall showed that over 90 percent of the overwintering forms are 
parasitized by Angitia hellulae Vier. (identified by R. A. Cushman). 
One species of hyperparasite has been reared from the material. 
Although the larvae of this moth normally pupate on the plant near 
where they feed, on the leaves and along the midribs, during the cold
