The Bulletin. 7 



regarding insects and their names. 



In disciissinp; the cabbage insects in this bulletin we have given both 

 the popular and the scientific name of the species, and have indicated the 

 orJer and the jainUij of insects to which each belongs. It should be 

 remembered that the order is the most comprehensive group, and each 

 order is divided into a number of families. 



The great majority of our common insects may be grouped into seven 

 orders, as follows : 



1. The Orthoptera (Or-thop'-tera), including the grasshoppers, katy- 

 dids, crickets, roaches, etc. 



2. Hemiptera (He-mip'-tera), bugs, siich as chinch bug, terrapin bug, 

 lice, scale insects, plant lice, etc. 



3. JSTeuroptera (Neu-rop'-tera), lacewing flies, dobsons, dragonflies, 

 Mayflies, darning needle, mosquito hawks, etc. 



4. Lepidoptera (Lep-i-dop'-tera), butterflies, skippers and moths. 



5. DiPTERA (Dip'-tera), the true two-winged flies, such as houseflies, 

 mosquitoes, blowflies, horseflies, etc. 



6. CoLEOPTERA (Co-le-op'-tcra), beetles, such ae potato beetle, bill 

 beetle, flea beetle, June beetle, tumble beetle, tiger beetle, etc. 



7. Hymenoptera (Hy-men-op'-tera), bees, ants, and wasps. 



It is believed that this explanation and arrangement will be helpful 

 to those who are interested in learning how to recognize the different 

 orders of insects. 



CABBAGE INSECTS. 



Although there is quite a list of insects which attack cabbage to more 

 or less extent, yet the great bulk of damage in North Carolina is done 

 by cabbage louse, cutworms, terrapin bug and cabbage worms (of which 

 there are several different kinds). Less important injury is done by 

 flea beetles, cabbage maggot and fall army worm. 



THE CABBAGE LOUSE 



{Aphis hrassic(C.) 



Order Hemiptera, Family Aphididw. 



(Also called Turnip Louse, Collard Louse, Mustard Louse, etc.) 



Description. — A grayish or greenish plant louse not over one-eighth 



inch long which infests cabbage in great numbers, sucking the sap 



from the plant and causing it to wilt down and die. 



Injury in ISTorth Carolina. — The cabbage louse is one of the most 

 serious insect enemies of cabbage in North Carolina, standing with the 

 harlequin bug and cabbage worms as the three worst pests of the crop. 

 When conditions favor it, the louse appears on the plants in tremen- 

 dous numbers, often massed together so thickly that they are piled over 

 each other, each louse being able only to reach the plant with its beak 

 which is thrust into the leaf or stem. It is more destructive in the 

 eastern and central sections than in the west. It may be found on cab- 

 bage at any time of year and most published accounts state that it is 

 most destructive in late summer and fall. However, the great majority 

 of the complaints that have come to this office (and there have been
