NOTE ON THE HORJ^ FLY IN OHIO. 



BY D. S. KELLICOTT, COLUMBUS, OHIO. 



Since the full accounts of the Horn Fly given in Insect Life and elsewhere, T, as 

 many others, doubtless, have sought for it wherever I had an opportunity. I remember 

 no reports of its occuring west of the Atlantic border, but it certainly has a foothold in 

 central Ohio. During the first week of July last I found it in great numbers on the 

 farm of Mr. A. Freed, Pleasant Township, Fairfield County. Large patches were seen 

 on the backs and about the horns. The animals referred to had been dehorned, but the 

 fly, true to its instincts, congregated about the stumjjs. At Sugar Grove, 8 miles south, 

 a few were found, whilst at Rockbridge, 4 miles farther down the Hocking Valley, none 

 were to be found. There appears to be none north of the first-named station, as I had 

 a fair opportunity to examine cattle at Lakeside (Licking reservoir). They have not been 

 seen at Columbus. It seems from the limited observations I have been able to make 

 that it is spreading southward from near Lancaster. The Baltimore and Ohio Railway 

 passes but a short distance north of this place, and it is easy to see that it is possible, or 

 indeed probable, that it was introduced by transportation in cattle cars from the East. 



Mr. Smith stated that the Horn Fly was not injurious in any part of New Jersey 

 last year, stockmen adopting the plan of .spraying with fish-oil compound. He also 

 stated that the plastering of the dung was practised in his State in small stock yards. 



Mr. Howard said that even in large grazing fields this latter plan is often practicable 

 in spite of the objections which stock-growers urge. At the time when the flies are 

 ovipositing the cattle are generally congregated in some one spot for shade. 



Mr Lintner said that he heard of the fly in the southeastern portion of New 

 York State. 



Mr. Osborn said that there had been an unverified report of its occurrence in 

 Iowa. He believes that the plaster treatment of the dung will be practicable in his 

 State. 



Mr. Fletchtr said that many remedies which are considered impracticable by farmers 

 prove eventually to be very practicable, and he instanced the poisoned ball system for cut 

 Avorms, and said that standing grain can be sprayed with knapsack pumps. 



NOTES OF THE SEASON. 



BY ELEANOR A. ORMEROD, ST. ALBANS, ENGLAND. 



The Secretary then read the following, which was addressed to the President, Mr. 

 Fletcher : 



You pay me the compliment of suggesting that I should send a short report of my 

 entomological work of this year up to present date. But though it would indeed be a 

 gratification to me if anything I could mention should be thought of interest, yet I feel 

 such a hesitation in submitting anything I can say to sucli a supremely well skilled tribu 

 nal as that of the meeting of the Association of Economic Entomologists at Washington, 

 that I will rather endeavour to give, in letter form to yourself, some notes of what we 

 have been doing, from which, if you judge fit, you could lay some points, with my best 

 respects, before the meeting 



Paris green. — I think that I maj' now report the use of Paris green in fluid state 

 (as a remedy for attacks of orchard caterpillars) as having thoroughly taken root in this 

 country. It is not yet as widely spread as could be wished, but the very large amount 

 of inquiry sent me during the spring and summer months as to the nature and method 

 of application of the remedy gives me good hope that its use is extending.
