Methods for Studying Insects Affecting Live Stock 



The party spent a very interesting morning in the Dallas laboratory of the U. S. 

 Bureau of Entomology, where Mr. Bishopp and his associates explained the various 

 projects under investigation. There were general discussions on laborator^^ and 

 ofhce record systems, on photographic methods, and on systems for filing and 

 recording alcoholic material in which the Bureau methods were thoroughly 

 discussed and demonstrated. Various fly traps were studied and their merits 

 and demerits pointed out. Mr. Bishopp gave us an interesting talk on the use of 

 traps under range conditions and also explained the reaction of various species of 

 flies toward various baits. Dried egg, according to Mr. Bishopp, is the best all- 

 around bait for a number of species of flies which are of economic importance to the 

 stockman. It is suggested that the southern entomologist may get some information 

 of great value to them if they will write to Mr. Bishopp for information 

 on the use of this bait. 



The formal session of the Cotton States Entomologists was opened at 3 p.m. at the 

 Jefferson Hotel. Dr Hinds presided. The first paper on the program was on the 

 Camphor Scale, by Mr. E. R. Barber of the Bureau. 



The Camphor Scale Situation 



Mr. Barber pointed out that we knew practically nothing about the camphor scale. 

 The pest is known to occur in Japan on citrus stock but it seems to be of little economic 

 importance there. Outside of Japan the pest is not known to occur at any place 

 other than New Orleans. This insect is supposed to have been introduced by N. 

 Cook & Son, rose specialists of New Orleans, in a large shipment of roses from 

 Alhambra, California. 



The rapid spread of the pest has been very striking. It was discovered August 4, 

 1920 by Mr. Barber on some camphor trees in front of his home, not far from the 

 Cook nurser}'' ; the scale was found on every species of plant around the place. The 

 following spring the scale had spread to 27 blocks, with the original infestation as a 

 center. Later there was a severe storm and it was found that scales were blown to 

 a point two miles away from the original infestation. 



In June 1921 the city of New Orleans appropriated $5,000 for eradication. This 

 was later increased through various means to $15,000 and later the state made an 

 appropriation for eradication. The first step consisted in making a survey to ascer- 

 tain the amount of infested territory, which was about four square miles. There 

 wereabout seven or eight nurseries in this territory and to these nurseries 148 isolated 

 infesta tions in the rfest of the city were definitely traced. A later survey turned up 200 

 more infestations. All told 450 isolated infestations were found outside of the original 

 infested area and these were cleaned up. The isolated infestations discovered in the 

 first survey were traced without exception to nurseries in the infested area. All of 

 the balance occurred along paved and much traveled streets which passed through 

 the infested area. It appeared that the latter infestations were spread maUciously. 



A long series of experiments were carried on to determine a satisfactory spray.
