over the investigational work at the Japanese Beetle Laboratory at Riverton 
and observing various methods of control in the field. About 100 acres of 
demonstration orchards were visited, The orchards consisted of peaches, 
apples, cherries and grapes. The growers expressed themselves as well 
pleased with the-results obtained; almost perfect control was secured by 
following the recommendations issued by the laboratory on early ripening 
varieties of apples with one application of spray on June 25, During the 
trip a demonstration was held in one of the orchards, using the new at- 
tractive agent geraniol to draw the beetles into a limited area, where they 
can be killed by a contact spray. The contact spray, consisting of oleroresin 
of pyrethrum and soap, which has been developed at. the laboratory during the 
past season, was also demonstrated with remarkably good resuits. The trip |
