2 CIRCULAR 16 8, U. S. DEPARTMENT OF AGRICULTURE 



By far the greater part of the publications, many of which contain 

 information of considerable value to entomologists in other countries, 

 are naturally published in the Japanese language, and consequently 

 are entirely inaccessible to all foreign workers except the very few 

 who have facilities for translation. In recent years an increasing 

 number of Japanese authors have followed the practice of presenting 

 a summary of their more extended papers in English, French, or 

 German ; and in some cases the entire text is given in two languages. 

 The writer's own observations (ii, i£) 2 , made incidental to eight 

 years' investigations on the problem of insect parasites in all parts 

 of the country, have also been incorporated in the present work. 



The biological and control notes presented regarding the more im- 

 portant species are of necessity limited. Whenever possible the more 

 important points in the life history, such as the number of broods 

 per year, the placement of the Qgg, the manner of feeding of the 

 larva, the place of pupation, and the stage in which hibernation 

 occurs, have been noted. 



Certain of the control measures mentioned, such as the collection 

 of adults, larvae, or eggs and the bagging of the fruit, are practicable 

 in Japan, though not in the United States, because of the different 

 conditions under which the various crops are grown and the lower 

 cost of farm labor.
