334 REPORT OF THE COMMISSIONER OF AGRICULTURE. 



But the tomato-worm is uot confined to the fruit,* as is shown by the 

 fact that several specimens were recently sent to the department by 

 Professor Willet with the remark that they were found boring into the 

 terminal shoots of tomato plants at Macon, Ga., early in September. 



Another common garden vegetable that is also injured by tlie boU- 

 Avorm is the garden pea. This Avas observed by Mr. Trelease in Ala- 

 liama. A boll-worm would bore a hole into tbo pod and devour its 

 whole contents before leaving it for another. 



Of allied plants, the boll-worm has been obserA'ed to eat the chich-j)ca 

 {Cicer arietinum) in Europe, the common cow-ijea of the South, and the 

 common string-bean {Fhaseohts vulgaris), and Erythrina licrlacea^ a le- 

 guminous plant common in the South, i\I. J. Fallon {Insccfologie Agri- 

 cole, 1869, p. 205) records Scliothis as feeding upon the chick-pea. He 

 found the young worms to feed upon tbe leaves and the large ones to 

 bore into the pod. With the cow-j)ea, upon v.hich Mr. Trelease found 

 it feeding very abundantly, and in which the pod is more fleshy and the 

 pease separated by fleshy partitions, it often pursues a different course 

 from that which it takes with the common garden pea; it often bores 

 into one chamber of the pod, eats the seed in it, and then, instead of 

 cutting through the partition to reach the next, bores another hole from 

 the outside. The same observation precisely AA'as made concerning their 

 habits when feeding upon Erythrina. As to the string-beans. Professor 

 Riley records that it was found eating them around Kirkwood, Mo., by 

 Miss Tvlary Slurtfeldt. 



This dei)artmeut has also received specimens of the boll-worm from 

 D. Landreth & Sons, of Philadelphia, as quite seriouslj' infesting fields 

 of Lima beans. 



The pods sent were each x>ierced by one hole of an eighth of an inch 

 or more in diameter, and the contents in e^ery case had been destroyed. 



Of other useful plants which the boll- worm occasional!}^ feeds upon 

 we would mention pumpkins {Cucurhita pepo) as recorded by Mr Glover 

 in the Department of Agriculture Eeport for 1S70, p. 84, and red Y'^^]}- 

 ■pers {Ca])sicum a7immm), as recorded by G. H. French in the Seventh 

 Ee])ort of the State Entomologist, of Illinois, p. 102. Mr. Glover also 

 states that " a young boll-worm was found in the corolla of the flower 

 of a squash, devouring the pistil and stamens." 



Mr. French also records the fact of finding what he considered to be 

 the boll-worm in the iiods of IUMsgus grandijlortis, the large flowered 

 rose mallow. 



Mrs. Treat discovered, in the course of lier observations upon Ilelio- 

 tJiis, that many individuals of the first brood ate into the stems <.-f the 

 garden flower known as Gladiolus, and not only into the stems but into 

 tiie flower buds also. 



As legards its European food-plants. Professor Eiley quotes from M. 

 Cli. Goiu-ean's Insectes Xuisibles, Second Supplement 1865, i). 132, to the 

 elfect that it not only infests the ears of Indian corn, but devours also 

 tlie heads of licmp and the leaves of tolacco and of lucerne {Mcdicago 

 ti'dira). 



And now let us turn to ihv consideration of tlic l)ol!-worni on cotton.
