II.— THE GRANULATED CUTWORM,^ AN IMPORTANT 

 ENEMY OF VEGETABLE CROPS IN LOUISIANA. 



By Thos. H. Jones, 

 Entomological Assistant, Truck-Crop Insect Investigations. 



INTRODUCTION. 



Cutworms periodically cause serious damage to vegetable crops 

 in Louisiana and adjacent territory and it is seldom that they do not 

 occur, a*t least in small numbers, in land planted to such crops. 

 Complaints of injury are 

 often made by people who 

 have small gardens as well 

 as by those who make the 

 growing of truck crops 

 their livelihood. 



Observations made in the 

 State from 1914 to 1917, 

 inclusive, indicate that the 

 granulated cutworm {Fel- 

 tia an7iea?«.Treitschke) (jfig. 

 1) is the principal species 

 attacking vegetables.^ 



Of 1,431 cutworms, rep- 

 resenting collections made 

 from about injured plants at Baton Eouge during the months of 

 April, June, July, August, October, November, and December, of 

 1915, 1916, and 1917, 1,345, practically 94 per cent, were identified 

 as Feltia annexa. The proportion of this species, in one collection, 

 was as low as 76 per cent, but at other times it exceeded 90 per cent. 

 The remainder of the collections noted was composed of 47 larvse of 

 Agrotis ypsilon Rottemburg (3.2 per cent) , 35 larvae of Feltia male- 

 fda Guenee (2.5 per cent) , and 4 larvse of undetermined species. 



^ Feltia a/nneosa Treitschke. 



2 Messrs. C. E Smith, J. L. E. Lauderdale, and M. R. Smith, who were stationed at 

 Baton Rouge, La., for the Bureau of Entomology during this period, rendered valuable 

 assistance in the investigations upon which this paper is hased.
