State Plant Board (September 19): It is "believed that the 
Argentine ant is now completelj' eradicated fron Columbus over 
the largest' area in the world in which this pest lias been 
exterminated. A thorough scouting of the previously infested 
areas, block by block, this summer failed to reveal but two 
colonies of the ants, which were promptly destroyed by oil 
and fire. 
About 76 city blocks were badly infested with the ants at 
one time. About 40 other places in Mississippi have eradicated 
the Argentine ant in cooperation with the State Plant Board, 
but the area cleared in Columbus is the largest. 
C. Lyle and assistants (September): The Argentine ant 
situation in this vicinity is very encouraging at the present 
time, no Argentine ants having been found thus far at four of 
the previous infestations, namely, Grenada, Puckhill, Beattjr, 
and Kilmichael. They have also been reduced to a very small 
area in the city of Water Valley, and only a few have been 
noticed in the cities of Winona, and Tillatoba. The Argentine 
ant is very annoying to residents in places where no control 
campaign was conducted last j^ear. In Brookhaven, where a 
campaign was conducted in March, 1929, these ants are numerous 
in only a few residences at this time. The size of the Argentine 
ant infestation is greatly increased at Rodney, owing to overflows 
of the river in 1927 and 1929. Fire ants ( Solenopsis geminata 
Fab.) completely destroyed plantings of fall turnip greens in 
many gardens 'in 'G-eorge and Ferry Counties. Ants completely 
destroyed a 5 acre field of beets sown late in August 
at Lucedale. Florida harvesting ants ( Pogcnomyrmex be.dius Latr. j 
dot. M. R. Smith) dug up the seeds, taking them to their nests; 
and Eon ants (D. py ramicus Roger, det. M. R. Smith) chewed off 
most of the plants that came up, leaving a bare field. 
Texas S. W. Clark (August 27): There was more damage than usual 
this summer at Weslaco by Solenopsis geminata Fab. attacking 
citrus. The indicata.ions are that the infestations will be 
particularly severe during the fall months. 
CHEESE MITE (Tyroglyphus siro L. ) 
Washington W. W. Baker (September 12-19): Two brands of small packages 
of cheese were found infested in two different stores at Puyallup; 
all three packages had been wrapped in tin foil. 
SIXVERFISH (Lepisma sac char ina L. ) 
Connecticut N. Turner (September l): Silvcrfish (species not identified) 
badly damaged paper newly applied on four rooms at Guilford.
