numbers of leafhoppers migrating into the "beet fields in fall of 1939 were not 
alarming. Weather conditions during fall and winter were favorable to the in- 
sect and breeding occurred in the beets, which was unusual. Curly-top injury 
in the Salt River Valley was more severe than at any time since the industry 
was started in 193 5 • I* 1 the Mesilla Valley practically all beet varieties wer 
grown from resistant seed and very little damage occurred. Boot leafhopper 
migrations into seed crops in fe,ll of 19^0 in Salt River Valley were not large 
Moderate populations infested the fall crop in Mesilla Va,llcy, IT. Mex. 
In soxithern Idaho and northern Utah considerable* numbers of leafhoppers 
went into hibernation, but in California very low populations were present for 
hibernation. 
MEXICAN BEAM BEETLE 
During 1940 the Mexican bean beetle, was far loss numerous than usual in 
the Ohio River Valley in Ohio. Foliage injury to unsprayod garden beans along 
the Ohio River did not exceed 50 percent at any time and in most instances was 
less than that, as compared with conditions that prevail in most seasons, when 
unsprayod beans are completely defoliated at certain times; however, in the 
vicinity of Elyria, in the northern part of the State near Lake Erie, consider- 
able damage was done and it was necessary to spray or dust the bean crop. In 
central Ohio it was also fairly numerous, but loss so than in 1939* (H. E. 
Howard., Bureau of Entomology and Plant Quarantine, U. S. D. A.) 
The Mexican bean beetle passed the winter of 1939-40 successfully in 
eastern Virginia and, owing to unseasonably cold weather in April, began emerg- 
ing about a week later than usual. The peak of emergence of overwintered, 
beetles from hibernation occurred in the la.st week in May. The beetle popula- 
tion in many fields of spring snap beans was unusually large, the average in- 
festation on May 27 being 37 beetles and 37 egg masses on 25 feet of row in 1 
field under observation. The beetle caused severe damage to bean foliage in 
many untreated, fields of early snap beans but failed to seriously affect yields 
owing in most instances, to the advanced state of plant growth at time of attar 
Although a large population of first-brood beetles was present on summer crops 
of beans early in July, the infestation was practically wiped out as a result 
of an unprecedented heat wave throughout the a.rea the latter part of the month. 
Damage to fall beans was therefore unusually light and insecticide sales wore 
lower than in previous years, according to some dealers. (L. W. Brannon,

TOMATO EEUIT WORM 
The tomato fruitworm was very abundant along the Ohio River in the vicinit 
of South Point, Ohio, during 1941, when the percentage of wormy fruit reached 
44. Records were taken every few days from June 29 to September 20 and. it was 
found that the percentage of wormy fruit ranged from 15 to 44, ' reaching a. peak: 
on July 3 end a secondary peak on September 10. At Columbus and Marietta, 
Ohio, the natural infestation was very light and. it is believed that this was 
generally the case throughout the State. J. J. Davis, of Indiana, informed, 
me that there was no appreciable damage to canning tomatoes in Indiana during 
the 1940 season, (U. F. Howard, Bureau of Entomology and Plant Quarantine, 
U. S. D. A.)
