INSECTS INJURIOUS TO GLOBE ARTICHOKE. 5 



Cutworms, the predominating species apparently being Feltia 

 annexa Treitschke and Agrotis ypsilon Rottemburg, cause some in- 

 jury, especially during the cooler months of the year when only the 

 smaller developing leaves are present on the plants. 



Larvae of two agromyzid flies, Agromyza platyptera Thomson var. 

 jucunda Van der Wulp, and Agromyza sp., 1 have been found min- 

 ing in the leaves and the membracid Entylia sinuata Fabricius 

 breeds on them. The leaves are also fed upon to some extent by 

 various other insects, among them the larva of the cabbage looper 

 (Autographa orassicae Riley) and the adult of the southern corn 

 rootworm {Dmhrotica , duodecimpunctata Olivier). 



1 Determined by F. R. Cole. In 1914 Mr. I. J. Condit found larvse of Phytomyza (Napo- 

 myza) lateralis Fallen working as leaf miners on globe artichokes at Berkeley, Cal. 

 The reared adults were determined by Mr. Frederick Knab, Bureau of Entomology.
