-15- 
sizes were observed to have penetrated the center portion of heads 
of cabbage of the fall crop, evidently seeking protection. The 
present population appears to be a,bout what is found during the 
average season. 
Florida. J. E. Watson (Februp.ry 21): There are sone cabbage loopers 
on cabbage. 
Louisiana. C. E. Snith and R. W. Brubaker (February 29): A single larva 
was observed on cabbage at Houma, February 26, while none h,a,ve been ■ 
found in the field at Baton Rouge, since the low temperatures which 
occurred the last half of January. The population was at a very low 
ebb for about a month previous to freezes. The population of this 
species is normally from low to absent on field crucifers in this area 
from about the middle of December to the last of March or first of 
April, and seldom reaches destructive numbers until the latter part 
of April. 
Texas. P. T. Eihcrd (February 21): The cabbage looper was observed on 
cabbage at Starr, Hidalgo County, and in Ca.meron County from January 
1 to 15 . 
DIAi\^OHDBACK MOTH ( Plutella maculipeniils Curt.) 
South Ca.rolina. W. J. Reid, Jr. (February 29) : Despite the below normal 
tempera-tures in the Charleston area., this insect has been found in 
limited, but apparently about normal, numbers throughout the winter. 
A small brood of larvae developed on young plants of the spring crop 
of cabbage during Janup.ry and early in February, pupated about the 
middle of the month, and newly hatched larvae of what appears to be 
another brood were found on February 29* As usual, the low tempera- 
tures seem to hold the species in check. 
Louisiana. C. E. Smith and R. W. Brubo,ker (February 29): Observations 
made from Baton Rouge to near the Gulf coast south of Houma, indicate 
that the larvae survived the January freezes better than either the 
cabbage looper or the imported cabbage worm. In coiunts made on 
collards at Baton Rouge, during several weeks previous to and since 
the freezes, there was little difference in the population, which con- 
sisted of an average of approximately 50 larvae per 100 collard plants. 
Texas. P. T. Rihcrd (February 22): Diamondback moth observed on cabbage t 
at Starr, Hidalgo County, and in Cameron County from Janua.ry 1 to 15- 
California. J. Wilcox (January I 5 ): At 01i''.'’e , southern California, where 
cabbage is .just beginning to head, 20 percent was infested with 
cabbage looper and diamondback moth larvae.
