DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 



there were over twice as many apples on the count trees, which would 

 tend to decrease the total percentage of wormy fruit. However, 

 as will be noted later, there were 573 more codling-moth larvae on 

 the one-spray plat than on the lime-sulphur demonstration plat. 



The Bordeaux demonstration plat (No. II) did not give as good 

 results as the lime-sulphur demonstration plat, the percentage of 

 fruit free from codling-moth injury being 84.93, practically the same 

 as on the one-spray plat. The notable difference between the two 

 demonstration plats in percentage of sound fruit may be due to its 

 location relative to the unsprayed plat or to some other local con- 

 dition. 



Table XVII shows the places of entrance of fruit by total larvae 

 for each tree of each plat.
