COWPEA. 



(Vigna ungiiiciilata'WaA]). Family Leguminosse.) 



The cowpea is extensively raised in the country as well as many other parts of the 

 Avorld. Shipments of the peas might easily introduce pests. (See Beans, Peas.) 



CRUCIFERS. 



(Family Cruciferse.) 



Various insects attack several species of crucifers and for convenience are grpuped 

 under a general heading. 



Phyllotreta spp. 



(Orucifer Leaf Beetles. Chrysomelidse; Coleoptera.) 



Species: Ph. undulata Kutsch; Europe; cultivated crucifers. Ph. nemorum Lin- 

 naeus; Russia; rhubarb, hops, cabbage. Ph. atra Fabricius; Europe; crucifers. Ph. 

 crucijerx Goeze; Europe; crucifers. Ph. nigripes Fabricius; Europe; cabbage, rad- 

 ish, horseradiBh, rape, Reseda. :^Ph. armoracix Koch; Europe, introduced into 

 North America; crucifers, horseradish. 



Injury: The adults of all of these species feed on the foliage of cruciferous plants. 

 The larvae are not all known but they usually attack the stem or roots. The fact that 

 two of the species have been introduced into this country indicates the possibility of 

 the others also gaining admission . 



Description: The first two species are yellow striped, the others unicolorous.
