mowing and drying of the leaves after fruit- 

 ing, followed by burning for the early brood. 

 For the late broods applications of arsenical 

 poison can be used, thus destroying many of 

 the insects. 



Another leaf eater is the slug. This 

 insect appears in the spring as a four-winged 

 fly, depositing its eggs within the tissue of 

 the leaves or stem. Shortly after the eggs 

 hatch; and the larva or worm eats small 

 round holes through the leaves, until In 

 five or six weeks it develops into a pale green 

 worm nearly three fourths of an inch In 

 length. Just previous to the rest stage it 

 enters beneath the surface of the leaf, form- 

 ing a cocoon in which it rests, coming out 

 later as a fly. In the North one brood a year 

 Is common, two or more being usual for the 

 warmer climates of the Southern States. 



Arsenical poisons, sprayed on the foliage 

 of the plants, will hold the insect in check. 

 If the plants are in fruit, non-poisonous 

 Insect powders like pyrethrum or hellebore 

 must be used. After fruiting burning the 

 bed over after mowing the leaves will check 

 this Insect.
