WHOLE VOL. APPLIED ENTOMOLOGY HOWARD 431 



In addition to the Defensa Agricola, there is under the Ministry 

 of Public Instruction a National Institute of Agronomy in which 

 ]\Ir. G. B. Schurman was Professor. Professor Schurnian was 

 active in many of the movements in applied entomology in Uruguay, 

 and his comparatively recent death is greatly to be regretted. There 

 is at present in the National Institute a Professor of Entomology, 

 Agustin Trujillo Peluffo, and a Professor of Applied Zoology, 

 Gilberto Borras. 



PARAGUAY 



Economic entomology is comparatively new in this country. A 

 good entomologist, Mr. A. de Winkelried Bertoni, began work upon 

 the higher Hymenoptera nearly 20 years ago and published a long 

 systematic paper entitled (translated) " A Contribution to the Biol- 

 ogy of the Wasps and Bees of Paraguay." It was published in the 

 Annals of the Museum of Buenos Aires in 191 1. In 1917 he pub- 

 lished a paper relating to the edible Lepidopterous larvae that feed 

 upon certain species of bamboo. About 1923, there was created 

 in the Ministry of Fomento a Section of Agriculture and Agricul- 

 tural Protection (" Direccion de Agricultura y Defensa Agricola '" ). 

 and under this section there was a division headed by Seiior Bertoni 

 with the title Entomologist and Chief of the " Mesa Fitopathologia." 

 Under this organization numerous bulletins have been published, a 

 number of them relating to injurious insects and the remedies to be 

 used. Especial attention has been paid to the insects injuring fruits, 

 to those injuring cotton, to injurious ants, to the suppression of the 

 migratory locust, and, under the Section of Chemistry, there has 

 been an arrangement for the analyses of insecticide products. 



ECUADOR 



Very little has been done in economic entomology in Ecuador, 

 although some interest has been taken in entomological matters for 

 a long time. Medical entomology, however, has important applica- 

 tions there. Guayaquil was long notorious for yellow fever. After 

 the yellow fever mosquito discoveries had been generally accepted 

 throughout Latin America and it began to appear that it was possible 

 to rid the world of this disease, one of the last and most difficult 

 tasks was to clear up Guayaquil. The attention of the International 

 Health Board and the United States Public Plealth Service was for 

 a time focused tO' a certain extent on this city, and the results were 

 very beneficial. The services of Dr. J. H. White of the United States 

 Public Health Service, who had done such efficient anti-yellow-fever
