264 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 15 



We feel that the Argentine ant has not received the attention that it 

 deserves. It is a pest of National importance, and should not be con- 

 sidered as a local problem. It is now established in many towns in at 

 least ten states. We hope that it will soon receive attention from the 

 Federal authorities similar to that now being given the European Corn 

 Borer, Green Japanese Beetle, Pink Bollworm and Gipsy Moth, with 

 which it ranks in importance as a pest. It is almost certain that the 

 further spread of this ant could be greatly checked. It could be brought 

 under almost complete control in many of the infested areas at a cost 

 far below what it costs to leave it uncontrolled, and it would pay to 

 completely eradicate it from certain areas. Our experience indicates 

 that this is entirely possible. 



Mr. E. 0. G. Kelly: I would like to ask Mr. Harned what size the 

 can is? 



Mr. R. W. Harned: The size of an ordinary tumbler. It can be 

 secured from the American Can Company of New Orleans. 



President George A. Dean: The next paper is illustrated by 

 moving pictures. 



IMPORTANT BIOLOGICAL FACTS ON THE OX-WARBLE 



CONTROL

Mr. R. C. Treherne: Does that apply for both species? 



Mr. F. C. Bishopp: Yes, the film was designed to cover both. 



Mr. L. Caesar: Would four treatments be sufficient, do you suppose? 



Mr. F. C. Bishopp: I would say that would be ample. We give those 

 at intervals of about thirty days. In that way we catch all of the grubs 

 that come up from the internal anatomy of the animal and develop on 

 the back. 



Mr. E. G. Kelly: Could you tell us some remedy other than just 

 squeezing the grubs out ? 



Mr. F. C. Bishopp: There was a part of this film relating to the 

 application of iodoform-vaseline to the grub holes, which was eliminated. 

 We have found that a considerable percentage of the grubs killed by this 

 ointment will emerge from the animal and others will be absorbed, but 

 without harm. 



Mr. E. G. Kelly: What percentage of the grubs that you squeeze 

 out of the hides mature as adults ?
