in northern Louisiana. By September 23 from 50 to 75 'percent of the cotton was 
defoliated. The moths probably spread from Florida into Mississippi, as .the 
first leaf" , "crns in that State mere found in the Gulf Coast region in George 
County on July 29, and later in Jackson Counter. On August lU they more reported 
from Tate and Washington Counties in the y ortho rn and western parts of the State 
and from Oktibbeha County in the northeastern part of the State on August 17. 
These infestations wore probably started by moths from ' Louis iana 'as they more 
closer to the infested are' s in Louisiana than to those in southern Mississippi, 
and also as most of the moms in the George County infestation yore reported to 
have been destroyed by parasites. 
The first leaf morns in Arizona in 1939 mere found at Sahuarito, Pina 
’County, on August 2S, exactly 1 month 1-ter than in 1938. (They had previously 
been reported from Marana on August 17 but this report mas not officially veri- 
fied.) 
Leaf morns mere not reported in South Carolina and Tennessee until Sept«nbe> 
and during October isolated and scattering infestations ,rr ere reported fron those 
States. Cotton loaf morn moths’ w -re reported at lights in Michigan on September 
15 and in large numbers by September 22, (R, W. Earned, Bureau of Entomology and 
Plant Quarantine, U, S. D. A.) 
COTTON FLEA HOPPER 
Cotton flea hoppers caused less damage than usual in. 1939 • They mere 
first reported on cotton on April 3, fa Calhoun County, T ox. In June they more 
reported from, many counties in. Texas, Oklahoma, Louisiana, Mississippi, South 
Carolina,' and Georgia, but only in limited areas in Texas, Oklahoma, and Missi- 
ssippi mere they numerous enough to cause serious' damage. During July and 
August they mere reported as present in South Carolina but doing no damage, and 
as causing some dahage in limited areas in Mississippi, Louisiana, Oklahoma, and 
Texas . ’ 
Hibernation studies in Calhoun County, Tex,, shomed that the peak of emer- 
gence in 1939 wa° on April 21, 7 clays earlier than in 193& and 1938, but later 
than in 1933, 193^, 1935 > and 1937*' During the week ended April 22, 62,6 percent 
of the seasonal emergence occurred. The emergence from hibernation in Calhoun 
County during 1939 averaged 19»^5 flea hoppers per croton plant, (R, W. Harned, 
Bureau of Entomology and Plant Quarantine, U, S. D. A, ) 
GLADIOLUS THRIPS 
The status of the gladiolus thrips during 1939 has not changed fron, that of 
the last two preceding years. Judging from the nature of inquiries received, it 
is still a serious pest in the small homeyard plantings, hut commercial growers 
seemingly are more familiar with its habits and injuriousness and therefore ore 
better able to cope with it, No new localities have been recorded, (C. A, 
Weigel, Bureau of Entomology and Plant Quarantine, U, S. D. A.) 
ROSE MIDGE 
Only a few reports were received on this pest during 1939 by the Bureau of 
Entomology and Plant Quaranti: e. It is felt that tho dearth of inquiries is due 
to the fact that this insect has had considerable publicity in the American Rose
