WHOLE VOL. APPLIED ENTOMOLOGY HOWARD 3I9 



Hygienic Institute at Zagreb Dr. N. Baranov, in charge of the Divi- 

 sion of Parasites, also works on injurious insects. The subject of 

 medical entomology is handled by several experts. Articles on ento- 

 mology are contained in the reports of the Ministers of Agriculture 

 and of Public Health, and there are two periodicals that contain ento- 

 mological matter, namely Gospodarska Smotra (Agricultural News) 

 and Gospodarski List (Agricultural Gazette). 



The Hygienic Institute at Belgrade is wonderfully well equipped 

 and is a thoroughly up-to-date institution. I visited it briefly in 

 1927 and was greatly impressed by the buildings and by the working 

 force. Dr. Eugen Dzunkovski is in charge of the Division of Para- 

 sites of this institution, and there are two entomologists, namely 

 Madame Anna Bragina and Dr. P. Vukasovic, who are working on 

 insects of economic importance. Madame Bragina was formerly an 

 assistant of Doctor Mokrzecki, and is trained in a variety of ento- 

 mological work. At the time of my visit she was investigating some 

 insects affecting tobacco fields, but fortunately returned to the city in 

 time for me to see her. In 1926, Madame Bragina studied the para- 

 sites of the codling moth and of certain other insects. Doctor Vukaso- 

 vic in 1928 published on the subject of an outbreak of Lecanium 

 corni. The same insect seems to have appeared injuriously in all of 

 the Balkan countries about that time. He also published in that year 

 an excellent article entitled "A Contribution to the Study of Ento- 

 mophagous Insect Parasites." This Serbian entomologist studied in 

 Paris and published in French many papers relating principally to the 

 host relations of parasitic Hymenoptera. His name in the French and 

 English publications is spelled Voitkassovitch. 



Doctor LanghofTer, whom I had the pleasure of meeting at the 

 Zoological Congress in Budapest in 1927 and who is a most intelli- 

 gent veteran, informs me that among the other workers on economic 

 entomology at present in Jugoslavia are Prof. Dr. Operman and 

 B. Hergula at Zagreb, Prof. Dr. Z. Kosacevic at Osijek, Doctor 

 Turina at Krizevei, Engineer Popovic at Sarajevo, P. Novak at Split, 

 Doctor Trausmueller in Susak, Doctor Sfarcic in Trogir, and Doctor 

 Simic in Skolje.' 



Doctor Langhofi'er informed me, under date of July 10, 1929, 

 that the Ministry of Agriculture was spending large sums on the 

 control of Lecanium on plums and prunes, and also large sums on 

 silk culture. 



* In 1926 I noted an article on tlie elm leaf beetle by R. Sarnavaka, published 

 at Zagreb.
