Mr. Reinhart's experience led him to the conclusion that it did not pay to dust 

 this year. In one case his dusted plots yielded no more than the check and in another 

 instance there was a 30% increase as a result of dusting. He had to put on 8 or 9 

 applications to put down the infestation. 



Dr. Hinds thinks it pays to dust early in the fruiting season and when the weather 

 is rainy. In hot dry weather it will not pay. Four or five applications under the 

 proper conditions will be profitable. As far as failure of dusting to control bollworms 

 is concerned Mr. Bishopp thinks that applications have not been made on time. This 

 should be done within two or three days after hatching of the bollworms begin. After 

 that time the worms can not be reached. Theoretically this period is about the time 

 when the field corn begins to harden. 



Moving Pictures on Insects Affecting Live Stock [Night Session.) 



Mr. Bishopp gave us four interesting and highly entertaining reels illustrating 

 Stable Flies, Horn Flies, Screw Worms and Ox Warbles. 



Each reel showed characteristic habits and poses of the species of flies, which 

 were illustrated, the mouth parts, stages of the insects, how they afi'ected stock and 

 methods of control of each species. Model traps were shown and methods of opera- 

 tion for each species were illustrated. Proper stacking of straw to prevent breeding 

 of stable flies was shown. The treatment of screw worm infested sores 

 and the destruction of carcasses was illustrated in connection with this pest. 

 By far the most interesting reel was the one , illustrating the Ox Warble. Every 

 southern entomologist who has occasion to do extension or teaching work should make 

 an effort to borrow this reel from the Bureau. The subject is handled in a very 

 entertaining and most popular as well as a very forceful way. Incidentally ox warble 

 eradication offers a most fruitful field for the entomologist's consideration. 



Extension Entomology ( Morning Session, Dec. 2) 



An informal discussion was carried on for about an hour before the pink boUworm 

 hearing, during which extension entomology was discussed. The feature of 

 the discussion was a plan submitted by Mr. Anderson in which he proposed to 

 divide the state of Louisiana into eight or nine districts. In each district there 

 was to be a competent entomologist who was to conduct not only inspection 

 and quarantine work but also extension work. He was to inspect all nursery stock 

 and other plant products of his district and was to be in complete charge of aU regulatory 

 work. In addition to this he was to give expert advice and help to the county 

 agents in his district. This work was to be divided into four seasons. In the winter 

 the work would consist largely of inspecting nursery stock and of making plans for 

 spring and summer. In the spring and summer demonstration spraying would 

 take up much time as well as regulatory work along this line During this 

 same period there would be sweet potato weevil eradication and in due time Argentine 

 ant eradication. 



It was generally agreed by all those present that there was a very fertile field 

 along the lines suggested by Mr. Anderson. 



Mr. Reppert was of the opinion that an extension entomologist could not afford to 

 jeopardize his work with the regulatory work as in all regulatory work much hostility 

 is engendered. It is also doubtful if men working under Government funds could be 

 allowed to do regulatory work. Under the conditions which obtain in Louisiana, 

 however, the plan is workable. 



The balance of the day was spent in connection with the pink boUworm hearing. 

 Most entomologists have by this time received the resolutions passed at that hearing 

 and it is thought that these resolutions will form the basis for the future pohcyof the 

 Federal Board of Horticulture in the eradication work.

RESOLUTIONS 



Passed by the Cotton States Entomologists in session at Dallas, Texas, November 

 30 to December 2, 1921. 



Whereas, the cost of eradicating the pink bollworm is insignificant in comparison 

 with the economic consequences to the whole United States as a result of the permanent 

 establishment of the pink bollworm in the South, and 



Whereas, the eradication work of the Federal Horticultural Board cooperating 

 with the States of Louisiana and Texas through the maintenance of non-cotton and 

 regulated zones has, in our judgement, showed that this pest can be eradicated, and
