PAPERS ON CEREAL AND FORAGE INSECTS. 



THE LEGUME POD MOTH. 



(Etiella zinckenella schisticolor Zell.) 



By James A. Hyslop, 

 Agent and Expert, Cereal and Forage Insect Investigations. 



HISTORICAL. 



The first mention of the legume pod moth (Etiella zinckenella 

 schisticolor Zell.) as of economic importance in the United States is 

 found in the unpublished notes of Mr. Theodore Pergande 1 in the 

 files of the Bureau of Entomology, and refers to a number of lima- 

 bean pods sent in by Mr. Albert Koebele from Eldorado County, 

 Cal., on July 21, 1885. The larvae were reported as doing consider- 

 able damage to the bean crop in that region. They left the pods and, 

 if not full grown, entered other pods to continue feeding or, if full 

 grown, constructed slight cocoons in the bottom of the rearing jar 

 and pupated. Adults emerged September 2 and September 15. 



A similar reference, 2 from the same source, refers to a number of 

 pods of Crotolaria incana collected by Mr. E. A. Schwarz at Cocoanut 

 Grove, Fla., on May 9, 1887, and sent to the Bureau of Entomology. 

 The larvae were eating the seed, and from these on May 16 an adult 

 emerged. From a second lot of seed pods from the same source 

 received on June 1, three more moths emerged on the 24th. 



On May 2, 1896, a number of pods of Astragalus sp. were received 

 by the bureau from Mr. C. L. Marlatt, 3 the material having been 

 collected at Neucestown, Tex., infested with larvae of Etiella zincken- 

 ella. On May 13 a braconid parasite issued, and on June 5 an adult 

 moth emerged. 



A single specimen was received from Mr. E. E. Bogue, 4 of Still- 

 water, Okla., on August 17, 1896, which he had previously reared 

 from the seed pod of Crotolaria sagittalis. 



Dr. F. H. Chittenden, 5 of this bureau, has published a paper on 

 this insect in which the records made bv Mr. H. O. Marsh are incor-
