on horsemint. Horseraint is more abundant this year than during the 
past 2 years. 
F. L. Thomas (May 23): The hatching or emergence of .flea hoppers 
from croton weeds prior to May lG was slightly greater than the aver- 
"" ""age, "but the number emerging per 100 weeds during the first 2 weeks 
of May exceeds that of any other year since 1925 . 
PINK BOLLWORM ( Pectinophora gossypiolla Saund.) 
Mexico. C, S. Rude (May 2S): Infestation is very light at Tlahualilo, 
Durango, less than 1 percent in squares. ITo bolls are yet available 
for examination. 
BEET ARMYWORM ( Laphygma cxigua Hbn. ) 
Arizona. ¥. A. Stevenson (May 2k) I Reports of May 13 indicate that con- 
siderable loss has recently "been caused to the young cotton in the 
Tucson district. The caterpillars feed principally on the seed leaves 
of the cotton "but in rare instances feed on the "buds and stems, killing 
the young plants. Where the leaves are destroyed and the "buds kept in- 
tact, the plants will undoubtedly recover if irrigated. However, the 
cotton will bo set back ah out 2 weeks. Approximately 2C0 acros ef 
cotton have "been replanted in the Tucson district owing to the ravages 
of these worms, and the majority of the farmers have given their cotton 
an extra early irrigation to help it recover. Similar damage has "been 
reported from the Salt River Valley, especially from the western part- 
Texas. A. J. Chapman (May 2k): Reports of May IS state that cutworms 
have injured young cotton considerably during the past week. It is 
estimated that about ICO acres of cotton was replanted in the vicinity 
of Presidio because of cutworm injury. Severe infestations have been 
noted in several alfalfa fields. Farmers are trying various methods 
of control— irrigating, poisoning, and cultivating. (Det. by C. Hein- 
rich. ) (June l): Parasites are exercising considerable control. 
In one alfalfa field under observation large numbers of dead parasit- 
ized worms were found. It is doubted that this armyworm will cause 
further damage in this aroa this year. 
California. R. E. Campbell (May l): The beet armyworm is rather abun- 
dant on sugar beets in the El Monte district, requiring the applica- 
tion of baits in a number of fields. Stands were so reduced in sever- 
al untreated fields that beets were plowed up. 
S. Lockwood (May 2k) : The beet armyworm has been responsible for some
