The cambium curculio ( Cono tracheitis anaglypticus Say) appeared in 
*ne of the most serious insect outbreaks that has ever occurred in the pecan- 
growing sections of southern Mississippi. The -walnut caterpillar ( Datana 
integer rima G. & R. ) was much more numerous than usual over the entire eastern 
pecan section, from Florida, to Mississippi. 
The citrus aphid situation in Florida has very materially improved. 
Very slight infestations were observed over the entire region previously so seriousl 
infested. A single serious infestation was reported from Louisiana.. 
TRUCK CROP INSECTS 
The harlequin bug ( l.fcrgantia histrionic a Hahn) was decidedly more 
troublesome than usual over the South Atlantic and Gulf region. 
The cabbage maggot ( Hylemyia brassicae Bouche) was in 1926 generally 
destructive from Massachusetts through the East-Central States to Wisconsin 
and Iowa. 
The known distribution of the Mexican bean beetle ( Bpilachna corrunta 
Muls.) has very materially increased during the past year. It was reported, 
for the first time in the State of Maryland, in Garrett and Washington Counties. 
In Virginia the insect has advanced to very nearly the eastern border of the 
State in Frederick, Page, and Culpeper Counties, In North Carolina it has 
reached the center of the State in Caswell County, and in Ohio the extension 
along the lake is now complete. In Indiana it has spread westward to Clinton 
County, and in Pennsylvania it has been found as far East as Dauphin County, 
near Harrisburg, and north to Venango Coaanty. 
The bean aphid ( Aphis rumicis !•) developed in unprecedented 
numbers in the cannery bean sections of Ohio, where it caused considerable 
losses to growers of lima and string beans. 
In southern Utah the beet leaf hopper ( Sntettix tenella Biker) 
was epidemic in 1926, and because of curly top the beet crop was practically 
a failure. 
The campaign for the control of the sweet potato weevil in the 
Gulf region of Mississippi and Alabama has been so successful that where 123 
farms in Pearl River County, Miss., were infested in 1923 but one farm was 
found infested in 1926, -and where 62 farms in Baldwin County, Ala., were 
found infested in 1925, but two showed any infestation this year. 
The turnip weevil ( Lis trod eres obliquus Gyll. ) was for the first 
time reported from California, where it was found seriously infesting carrots, 
spinach, and other garden truck at San Jose. In the eastern area of infestation 
by this insect the situation has changed but little since last year. 'The 
closely related species Listroderes apical is Waterh. was found for the first 
time in the State of Mississippi. Up to this year this species has been 
confined to Louisiana. 
The sweet potato beetle (Typ pphorus viridicyaneus Cr. ) has been 
reported as damaging sweet potatoes in Walker Connjry, Ga. This insect has __
