feeding period for each individual averages about nine or 

 ten days. When numerous, much of the foliage may be 

 destroyed. Several generations occur during the season. 



Methods of control of slug. 



Orchards that are well sprayed for the control of the 

 major insects are not likely to suffer from the peach slug. 

 It is only the trees in the home orchard or garden which 

 ordinarily receive scanty attention that are in danger of 

 injury from it. 



The pear- and cherry-slugs, both of which are similar in 

 general features to this insect, can be destroyed by dusting 

 them with air-slaked lime; or even very fine dry soil, if 

 dusted over the slimy bodies of the larvae, is usually sufficient 

 to kill them. 



Peach saw-fly (Pamphilius persicus) 



While not of serious economic importance, this insect 

 has been locally troublesome in a few sections. 



Appearance. 



The adult is a small, four- winged fly about f inch long, 

 reddish brown in color with yellow markings on the head.^ 

 The larva is about f inch long when fully developed and of 

 a bluish-green color. 



Distribution. 



Apparently the distribution of the peach saw-fly is fairly 

 wide, having been reported as working on peaches in Con- 

 necticut and in Nebraska.
