carried on for a number of years, there was practically no commercial damage 
in I93U and 1935. The eradication of wild cotton in southern Florida is just 
nor (December) getting under way for this season. M st of the wild cotton 
known to be infested was destroyed during the two previous seasons. (E. E,

The boll worm was observed breeding throughout the entire winter of 
I93U-35 on corn and other host plants in the vicinity of Brownsville, Tex., 
in the lower Eio Grande Valley. As a cotton pest this insect was more serious 
in 1935 than during any year since 1$25, This was especially true in north- 
ern and eastern Texas. The emergence in hibernation cages at College Station, 
Tex., in the spring of 1935 w & s 5*53 percent. The first egg was found there 
on March 22 and one first-instar larva was recorded on March 29, both instances 
being on alfalfa. The first moth was found in corn on April 5 and at that time 
eggs were prerent at the rate of 11 per 100 plants. There was a slight in- 
crease in egjjs the following reek, but daring the season the eggs were not as 
abundant on corn plants or silks as they usually are; however, enough worms 
developed to cause at least °'0 percent of the ears to be injured by the last 
of June. On cotton the arerage number of eggs ranged from less than 5 dur- 
ing the early part of July to 105 per 100 cotton terminals on August 10, the 
peak of the season. Three broods occurred on cotton, but only those in July 
and August caused serious damage. The September brood was not important. 
The past season was the first time that general poisoning was resorted to for 
boll worm control. Comparatively good yields were made in fields where poison- 
ing was done, but little fruit was set during the time the first and second 
broods on cotton were active in July and August, Fortunately, late frosts 
permitte:". the top crop of cotton to develop to maturity in that section of 
Texas, At Florence, S. C, , the insect caused little damage and was riot as 
abundant in cotton fields as in 19 5^- j when some damage was noted. In the 
hill section of Mississippi there was an unusually large number of eggs and 
larvae on cotton from June 20 to July 5> but for some reason practically no 
damage was caused in 1935* ^n the Delta sections of Mississippi and Louisiana 
the boll worm was present in about the usual small numbers on cotton and no 
particular damage was noticed. At Presidio in the Big Bend area of Texas 
boll worms were much more numerous than for several years. They were most 
abundant during June and July and, although they caused some damage to cotton, 
much greater damage was done to corn. In Oklahoma boll worm injury was 
light, except in some rank cotton in the eastern part of the State, (E, W. 
Earned, Bureau of Entomology and Plant Quarantine, U. S. D. A.) 
Note . — As a pest of corn this insect was remarkably scarce 
generally over the eastern half of the United States. In Idaho and Utah 
the insect was reported as ca.using more damage than usual. A serious out- 
break occurred on tomato in the Yakima Valley of Washington, In some plant- 
ings from 75 to SO percent of the fruit was infested. In the San Francisco 
Bay district and in southern California damage ranged from 5 to 25 percent.
