The cotton leaf worm appeared in all of the cotton- ag States 
earlier than usual. It was particularly atom -riant in parts of I :-? s , Okla- 
homa, Ar]:ansas, Louisiana, and Mirsissippi. . Hundreds of thousands of aci 
of cotton were treated in those States during August and September. At 
.Florence, S. C. , although leaf worms appeared 2 weeks earlier than in IS; 
they caused less damage and die. not completely defoli-te a single field in 
that vicinity. In the hill section of Mississippi, in the southern part of 
the State, the insect appeared only 10 days earlier, "but completely defoli- 
ated the cotton plants 30 days earlier than in 193^. During the last 10 days 
of August all fields in the southern p-^rt of the State were stripped, whereas 
in 193^ it '" ?s late in September "before this happened. As the crop was ex- 
tremely early and was mature before the leaf worms appeared, no damage was done 
to the crop. In the northern third of the State the insect was abundant 
after August 15 and caused damage where it was not controlled. Owing to the 
lateness of the crop in this section, it was necessary for many farmers to 
poison .two generations of the worms. In Washington County in the Delta sec- 
tion pf Mississippi the first leaf worms '-'ere noted on July 11 and by August 
3 the farmers were complaining about them. By August 2t the worms were in 
all fields, by September 7 some fields had been stripped, and by the end of 
September stripping was general. In Madison Parish, La., leaf worms may 
have caused some slight injury in a few isolated fields where stripping 
occurred in August, but in general this came after the cotton was mature and 
no injury was caused. In the vicinity of College Station, Tex.', the first 
moth was found in cotton the last week of June and the first worms were noted 
during the first week of July. By July 15 dusting was fairly general and was 
continued when needed until October, therefore a few cotton fields in that 
section of Texas were defoliated. The leaf worm appeared in May and June 
in southern and central Texas and many fields were poisoned in June. In 
some sections considerable damage was done, owing to the shortage of insecti- 
cides. In the Big Bend area of southwe stern Texas the infestation was much 
heavier than during the past few years. Many cotton fields in Virginia 
were defoliated in September. The moths made their appearance in the 
Northern States earlier than usual, being reported from Maine and "Michigan 
in August, and large numbers of them appeared in Washington, D. C. , in 
September. They were reported as fairly abundant in October in Illinois, 
Iowa, and Michigan. (R. \1. Hamed, Bureau of Entomology and Plant Quarantine,

The beet armyworm was unusually abundant on cotton during the spring 
of 1935 and caused considerable damage to the young plants in all the 
irrigated sections of the : ..'est and in Mexico. Several hundred acres had to 
replanted and poor stands were caused on numbers of other fields in the Big 
Bend area of Texas. Alfalfa was also badly defoliated. This was the first 
time that this armyworm has occurred in sufficient numbers in this area to 
cause economic damage to cotton. It was necessary to replant 200 acres of 
cotton, and other fields were damaged in the Tucson district of Arizona. 
Serious injury also occurred in the Salt River Valley, especially the west- 
ern part, and considerable acreage was dusted and irrigated for protection.
