The delicate white eggs are mostly laid at night in situations where the larvae 
are to feed. Eggs hatch in from 2 to 4 days and a single beetle lays on an average 
from 25 to 30 eggs. The larvae usually feed from 2 to 4 weeks and then enter 
the ground to pupate. In late summer and autumn the beetles issue from the 
soil and soon thereafter hibernate, probably in litter on the ground. In Georgia 
there are two generations of beetles each year, but from West Virginia northward 
there is but one generation annually. 
The species is probably attacked by at least two parasites. In West Virginia 
a hymenopterous species, Thersilochus conotracheli Riley, apparently attacks the 
larvae and in Louisiana a dipterous parasite, Myiophasia globosa Townsend, was 
reared from cotton bolls infested by the cambium curculio. 
Where this insect attacks peaches it will probably yield to jarring, spraying, 
and other methods used against the plum curculio. As a precaution against 
injury to the cambium of valuable trees, the edges of any wounds in the bark 
should be promptly pared smooth and the injured areas treated to a coat of white- 
lead paint or some reliable tree paint.
