syrphid larvae which escaped us and probably thousands of coccinellid larvae 
which it was not possible to find or count. This gives some idea of what the: 
total number of predators in all stages must be in an acre of heavily infested 
alfalfa. I expect to have this test duplicated later on peas. We have colon- 
ized most of these predators in a pea field as heavily infested with pea aphis 
as any of them are at present in an effort to ascertain whether control by 
predators’ is possible when they occur in very large numbers." 

W. A. Thomas, of Chadbourn, N. C., investigated an outbreak of the corn 
earworm on tomatoes in South Carolina and reported that this insect has caused 
considerable injury to the tomato fruits. 
R. E. Campbell, of Alhambra, Calif., Secretary of the Pacific Slope. 
Branch of the American Association of Economic Entomologists, attended the 
meetings at Palo Alto, June 24-25, where he presented a preliminary report on 
the use of calcium cyanide as a soil fumigant for wireworms.

C. E. Smith, of Baton Rouge, La., reports that the southern green stink- © 
bug (Nezara viridula L.) has been the cause of severe injury to watermelon and 
cantaloupe vines in Louisiana. At the time of his visit the insect had largely © 
disappeared, but considerable injury had already been caused, the growing tips — 
of the vines having been killed by punctures made by the insect. Cantaloupe 
vines suffered the heaviest injury. 
Reports from the Yakima Valley show that the wireworm appeared in unusu- — 
ally large numbers during the present spring, and has caused heavy injury to 
miscellaneous crops. This insect, known as Pheletes occidentalis Cand., is 
closely related to the cultivated-land wireworm Pheletes (Limonius) californicus 
Mann., which has been a consistent and serious pest of lima beans and sugar 
beets in the southern half of California. 
L. W. Brannon, of the Birmingham station, has just finished scouting the 
Thomasville, Ga., Mexican bean beetle infestation. This isolated area was first 
found to be infested in 1921, but during 19ce and 1923 the insect did not spread 
to any large extent and the infestation was regarded as light. Scouting during 
the present season has shown that the insect has not only been more abundant | 
than formerly but has extended its range in all directions, invading Grady 
County, which is located west of Thomasville. | 
Scouting for the Mexican bean beetle by H. L. Weatherby, under the direc- 
tion of N. F. Howard, in cooperation with the Georgia State Board of Entomology, 
has shown that this insect has invaded 16 new counties in Georgia along the . 
southern edge of the area previously known to be infested. 
ed In South Carolina five counties have been added to the infested area to 
ate. 
At the present time mo extensive scouting by the Bureau has been con- 
ducted along the northern border of the infested area.
