in the spring and feed for several weeks on the inner bark of pine 
branches and on the stems of seedlings and small trees. Adults 
developing from the overwintering larval and pupal stages appear 
in July and August. The life cycle may be completed in 1 or 2 
years. 
The insect breeds beneath the surface of the bark on recently 
cut stumps and logs, and on the main stems or branches of dead 
or dying trees. Attacks occur on the tree from the roots up to 
branches as small as one-half inch in diameter. Attacks also occur 
at the root collar and on the lower stems of apparently healthy 
young trees. Eggs are deposited in pockets chewed through the 
bark by the female. Normally, a pocket contains only one egg, but 
frequently as many as four or five are found in one. The larvae 
feed either upwara or downward or right or left from the site of 
the egg, usually following the grain of the wood. In large, in- 
fested material, they pupate in “chip cocoons” in the outer sur- 
face of the wood; in smaller diameter material, they pupate at the 
center of the stem. 
Damage is often severe in regions where there are large quan- 
tities of breeding material, such as fresh stumps in Christmas 
tree plantations and in stands under intensive management. -Be- 
cause of the scarcity of breeding material in natural pine stands, 
damage there is of little consequence. Damage in nurseries and 
plantations can be reduced by destroying breeding sites or render- 
ing them unsuitable for egg laying (250). 
The deodar weevil, Pissodies nemorensis Germ., occurs in the 
Southern States north to Pennsylvania and breeds in deodar 
cedar, imported Atlas cedar, cedar of Lebanon, and various 
species of pines. The adult is rusty-red to grayish-brown, has a 
long snout, and is about 6 mm. long (fig. 76).
