BULLETIN 1103, U. S. DEPARTMENT OF AGRICULTURE. 



pest is known to be present throughout the greater part of the 

 coastal region from Pasco County south along the west coast around 

 the end of the Peninsula, and up the east coast to Volusia County. 

 On the coastal line, however, the insect is mainly infesting the seaside 

 morning-glory. 



In Georgia an outbreak in Charlton County is under control. The 

 work has been so successful in this county that no weevils were found 

 during the fall inspection.

Fig. 19. — Monthly departures from normal temperature (solid black) and rainfall (white) 

 from September, 1920, to September, 1921, inclusive, in the region infested by the 

 sweet-potato weevil. (See also Table 9.) 



In Alabama the original infestation has probably been eradicated, 

 but the fall inspection disclosed a new though small infestation along 

 the coast in Mobile County. 



In Mississippi an attempt is being made to eradicate the weevil 

 from the four coast counties. Substantial progress has been made in 

 Pearl River, Hancock, and Harrison Counties, but the work is being 

 delayed in Jackson County on account of inadequate force. No 

 eradication work is being attempted west of the Mississippi River, 

 and in this area the weevil is slowly extending its range northward. 

 At the present time it has been reported in the vicinity of Shreveport, 

 La., as well as in two counties in southern Oklahoma. Should the 

 latter report be verified it will mark the first infestation north of the 

 Red River.
