p. m. About 50 per cent of those captured will have already deposited 

 eggs. 



Fifth. While in tropical and sub-tropical latitudes larvae may 

 be found all the year round, there is little doubt but that in this 

 latitude the species winters as pupae. Fall and early winter plowing, 

 therefore, should reduce the number passing the winter successfully 



AN ANNOTATED LIST OF THE LITERATURE ON INSECTS 

 AND DISEASE FOR THE YEAR 191 2 



By R. W. DoANE, Stanford University 



During the summer of 1911, Brues and Sheppard made careful 

 studies of the insect life in the environment of recent cases of acute 

 epidemic poliomyelitis. Their findings led them to believe that 

 Btomoxys calcitrans might be concerned in the transmission of the 

 disease. At one of the sessions of the Fifteenth International Congress 

 on Hygiene and Demography September 26, 1912, Dr. Rosenau an- 

 nounced that six out of twelve monkeys exposed daily for several 

 weeks to the bites of numbers of Stomoxys which had been allowed to 

 feed on other monkeys that had been inoculated with poliomyelitis 

 virus, became sick and showed symptoms of poliomyelitis. This 

 announcement has created profound interest in all medical and ento- 

 mological circles and h'as led to a long series of investigations by physi- 

 cians and entomologists. In October, 1912, Anderson and Frost of 

 the United States Public Health Service repeated these experiments 

 and their results seemed to confirm the findings announced by Rosenau. 

 The results of no other experiments have yet been announced and it 

 remains to be shown whether this is a usual method of transmission 

 in nature. References to only a few of the most important of the 

 many articles and comments on this subject are given in the following 

 list. 



The Simuliidse, too, have continued to receive a great deal of attention 

 on account of their possible. relation to pellagra. Forbes, Hunter and 

 Garman have made detailed studies of the Simuliidae of Illinois, Kansas 

 and Kentucky respectively and while they find much in support of 

 Sambon's theory, the fact that these flies are really the carriers of the 

 virus that causes the disease has been by no means proven. 



A small outbreak of plague in Cuba again awakened the people, 

 particularly on the Gulf and Atlantic Coast, to the necessity of keeping 

 the seaport towns as free as possible from rats. 



The name of another martyr to scientific medicine was added to
