In the laboratory at Paris bollworms were fed on the following 

 plants, which were eaten with evident relish:

Gourd. 



Rose. 



Bindweed. 



Cotton. 



Cucumber. 



Amarantus spp. 



Stachys agraria. 



Tomato. 



Nasturtium. 



Tobacco. 



Physalis angulata. 



Apple. 



Castor bean. 



Catalpa. 



Solidago sp. 



Peach. 



Millet. 



Blackberries. 



Carina indica. 



Irish potato. 



Alfalfa. 



Bermuda grass. 



Datura stramovium 



Sweet potato. 



Taraxacum vulgare. 



Rudheckia sp. 



Chenopodium sp.

Helianthus tuberosum 



. Poke weed.

Green peppers. 



Solanum spp. 





Squash. 



Okra. 



Erigeron spp. 





The food plants of the boll worm, as at present known, are thus seen 

 to number TO, distributed in 21 natural orders. If to these be added 

 the plants on which the larvae have been fed in confinement, the list 

 becomes somewhat increased. 



STATUS OF BOLLWORM IN FOREIGN COUNTRIES. 



Throughout its extended range the bollworm is nowhere so well 

 known as in the southern United States in connection with its injuries 

 to the cotton crop. Its injuries in foreign countries are, however, in 

 some sections not inconsiderable, and attention may appropriately be 

 called to its status as a pest in other countries than our own. 



Throughout the countries of Europe its injuries are, on the whole, 

 comparatively insignificant. In Great Britain and Ireland, according 

 to Mr. E. A. Shipley (in lit.), well-authenticated British specimens of 

 the moth are so rare as to sell at from $2.50 to $4 each. 



Dr. Paul Marchal writes that bollworms were observed by him 

 injuring tomatoes in middle France in 1900 and 1901, and also injuring 

 corn in north Spain. In Hungary, according to Dr. Josef Jablo- 

 nowski, moths are very rare and larvae are unknown. A related 

 species, Heliotliis dipsaceus Linn., is at times troublesome, feeding on 

 corn, flax, peas, potatoes, and other crops. 



Dr. Antonio Berlese, of the Royal High School, Portici, Italy, 

 advises (in lit.) that the bollworm in Italy attacks principally tobacco 

 and Indian corn. Its injuries are not ordinarily important, and gath- 

 ering the larvae b}'- hand and destroying them is the method followed 

 in its control. Three generations annually are considered probable. 



Concerning the status of the bollworm in Cape Colon}^, South Africa, 

 Mr. Charles P. Lounsbury, Government entomologist, writes that it 

 is one of the most common of the lepidopterous insects of the Cape, 

 its larva being well known to farmefs, fruit growers, and gardeners 

 alike. In feeding habits the larva is almost omnivorous, attacking 

 pear, prune, plum, peach, lucern (alfalfa), cabbage, tomatoes, corn.
