June, 22] o'kane: crop protection institute 211 



The results constitute a genuine contribution to scientific knowledge 

 and will be published soon as a bulletin of the Crop Protection 

 Institute. The project demonstrated the feasibility of looking 

 to the institute as at least one available means to bring about 

 profitable and desirable cooperation among investigators. The pro- 

 ject was not an expensive piece of work. It utiHzed, as it should, the 

 existing, well-equipped, and well-qualified agencies in the shape of 

 scientific workers and laboratory equipment in the several states con- 

 cerned. It simply brought these together in a mutually helpful re- 

 lationship. There appears to be no reason why the Institute cannot 

 serve as a means of ftirthering other broadly conceived and timely 

 investigations. 



During the year the Institute has been engaged in preliminary work 

 on a project relating to the Ox Warbles. It is well-known to entomolo- 

 gists that the two species of Ox Warble that we have in this country, 

 Hypoderma lineata and Hypoderma bovis, cause enormous losses each 

 year to farmers and stock growers, to the packing houses that must 

 sell grubby hides, to the tanners who must buy such hides and, eventu- 

 ally, to the public, who must pay an additional price for sound leather. 

 It has long been known that, technically speaking, it should be possible 

 to reduce damage by the Ox Warbles, at least in certain localities, for 

 the reason that the species is in position where it can be got at beneath 

 the hides of cattle at a certain period of each year. Cattle represent 

 a definite quantity to which access may be had. Researches by Bishopp 

 have disclosed a simple and not too expensive ointment that may -be 

 applied with excellent results. 



The Board of Governors decided to endorse an attempt to carry out 

 a program of control and elimination in a typical, stock-raising county 

 in the east, in which both species of warbles are present and are destruc- 

 tive in marked degree. The Institute sought the assistance of the Tan- 

 ners' Council, an organization representing the large tanning interests 

 of this coimtry, and was successful in securing from them an appropria- 

 tion of $9,000, extending over a period of three years, this appropriation 

 being contingent on the securing of other necessary fimds from other 

 sources. Approaches were made to the authorities of several counties 

 in New York state with encouraging reception. Support was sought, 

 also, from the Institute of the American Meat Packers, but in the 

 recent conditions in the business world this source did not materialize. 

 Other avenues are now being approached. 



It is planned to carry out, if possible, some necessary preliminary 

 work this present winter and it is expected that the project will, even-
