under. Spraying with Black Leaf 40, diluted 1 part to 500

Slug. The slug is the larvae of a small black fly. It is 

 about one-fifth of an inch in length. The slug attacks both 

 the cherry and the pear. In reality it is the pear slug which 

 often feeds on the cherry. The adults appear in the spring 

 and lay their eggs in a little slit made for that purpose on the 

 under side of the leaf. The egg hatches into a little worm 

 which soon becomes covered with a brownish, sticky, slimy 

 material. The body of the slug is swollen in front and tapers 

 behind, resembling a tadpole. The larvae feed upon the upper 

 surface of the leaves, eating only the upper layer and leaving 

 the skeleton of veins and the lower epidermis to turn brown 

 and die. Badly infested trees lose all of their leaves by mid- 

 summer. The fruit becomes stunted and fails to mature, 

 and the vitality of the tree is greatly weakened. In severe 

 infestations the trees appear to have been swept by fire. 



When only a few trees are attacked by the slugs, the insects 

 may be destroyed by one or two applications of freshly 

 slaked lime dusted on the leaves. On larger tracts arsenate 

 of lead at the rate of 2 pounds to 50 gallons of water should 

 be used.
