SMALL BEETLES INJURING LEAF AND STEM 151 
There is one brood of this species in the North, but in the South two 
generations are recorded. The adults hibernate in any convenient 
shelter or in the ground. 
Where possible, young plants should be protected with cloth or wire 
sereen until they have got a start. Lacking this, it is wise to plant an 
excess of seed, thus allowing for the thinning that the pest will do. 
It is difficult to poison the beetles, because they will hunt out parts

using 4 or 5 pounds to 50 gallons of water. 
Many repellents have been tried, but most are of little use when the 
beetles are numerous, and their effect seems to last only a short time. 
Probably the best is dry-slaked or air-slaked lime with which has been 
mixed flowers of sulphur. Fine road dust or tobacco dust will drive 
them away from the plants temporarily. 
Beans or squashes planted ahead of the main crop will in a measure 
protect the latter. Removal of crop remnants, and general cleaning 
up of the garden in the fall, will help to avert serious injury the next 
Season.
