MISCELLANEOUS FEEDERS 
JAPANESE BEETLE (Pooillia japonic a Newm.) 
(Bur. Ent. News Letter No. 101, September). "Recent preliminary 
examinations for the presence of Japanese beetle larvae in fields in 
the vicinity of th9 laboratory chow a heavy increase in the number 
of grubs compared with the number present a year ago this time, in 
some cases running as high as 100 per cent or noro increase. It is 
expected that the regular grub survey to be made a little later in 
the fall will show a general .increase in density of grub infestation 
throughout the infested territory as a whole.*' 
" L A serious injury to a number of the greens in local golf courses, 
as a result of the abundance of Japanese beetle larvae, has been 
found. The greens offer ideal facilities for egg depositions by 
the beetle during the season, and it is quite apparent that the 
effect of these heavy egg depositions will be serious, possibly 
necessitating the rebuilding of infested greens."
