DKCIDUOUS FRUIT INSECTS AND INSECTICIDES. 



The three band records have been referred to as the Lake Shore 

 experiments located near the shore of the lake southwest of Douglas ; 

 the Saugatuck experiments, 2 miles from the lake and northeast of 

 Saugatuck, and the New Richmond experiments, near the village of 

 the same name, 7 miles from the lake. Of these the Saugatuck 

 experiments represented closely the locality of the field station and

the results from these last band records have been used to supple- 

 ment the laboratory rearing experiments. 1 Practically all of the 

 apple trees used in these experiments were old and badly neglected, 

 and none of the trees had for some time been sprayed with a poison 

 spray, so that the codling moth had for years developed normally 

 and unchecked in the above orchards. 



1 During 1909 and 1911 the band-record experiments, which in 1910 were interrupted on account of the 

 absence of fruit during that season, were carried out in the orchard on the grounds of the station.
