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 asa 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.
