592 Report of the Entomologists of the 



(3) Were the worms checked by parasites, predaceous insects, 

 disease and other natural agencies? 



(4) If convenient will you kindly give the dates of previous 

 outbreaks, if any? 



Answers were received from forty-two states, and may be 

 briefly summarized as follows: 



From New Hampshire, Vermont, Massachusetts, Rhode Island, 

 Connecticut, New Jersey, Delaware, North Carolina, New York, 

 Pennsyh.iiia, West Virginia, Ohio, Tennessee, Michigan, Indi- 

 ana, Illinois, Wisconsin, Minnesota, Iowa, Missouri, North Da- 

 kota, South Dakota, Nebraska and New Mexico reports were 

 received showing that the army worm, L. unipuncta, was pres- 

 ent in injurious numbers last year, and that, in most cases, oats, 

 rye and corn were severely attacked. Reports from Maine, Wv- 

 ginia, South Carolina, Georgia, Alabama, Mississippi, Arkansas, 

 Texas, Colorado and Arizona state that this species is known 

 to occur in these states, but was not present in noticeably in- 

 jurious numbers last year. From Louisiana, Oklahoma, Wyo- 

 ming, Montana, Idaho, Washington, Oregon, Nevada and Cali- 

 fornia we received the report that this species of army worm 

 was not known to occur within their borders. We did not hear 

 from the remaining states. 



As to the number of broods, Dr. Harvey, of the Maine State 

 College says: "We generally take a few of the moths at sugar 

 in June and more abundantly in September. This would indi- 

 cate hibernating larvae or two broods." Dr. Smith, of the Nev/ 

 Jersey Agricultural College, says that " there seem to be four 

 in the southern portion of the state, and probably three broods in 

 the northern sections." In nearly every other instance the re- 

 plies state that at least two broods are known to occur. Dr. 

 Otto Lugger, of the University of Minnesota, says he now thinks 

 that but one brood occurs in Minnesota. In nearly every instance 

 the bulk of the injury was done by the first brood, and with 

 but few exceptions the rejjnrts slate that the worms were checked 

 chiefly by a Tachina fly })arasite.
