INJURIOUS TO CABBAGE AND CRUCIFEROUS CROPS 365 



The Imported Cabbage Webworm * 



Sometime in the early 90's another cabbage pest was imported 

 from Europe, where it is common in the Mediterranean region, and 

 was first noted as injurious in South Carolina. Later it was found 

 in Georgia and Alabama, and it is probable that it has now become 

 more generally distributed through the Gulf and South Atlantic 

 States. 



The imported cabbage webworm is about one-half an inch long, 



FIG. 265. The imported cabbage webworm (Hellula undalis Fab.): a, moth; 

 b, larva side view; c, larva, back view; d, .pupa three times natural 

 size. 1 (After Chittenden, U. S*. Dept. Agr.) 



of a grayish-yellow color, striped with five brownish-purple bands. 

 Its name is received from its habit of spinning a silken web, 

 beneath which it retreats when not feeding, and to which masses 

 of excreta and frass are attached. Cabbage and turnips have 

 been most injured, but various other cruciferse are attacked. 

 The parent moth has a wing expanse of about five-eighths of an 

 inch and the fore- wings are of a grayish color, mottled with -brown, 

 black and white as shown in the figure.
