TERMITES IN THE UNITED STATES. 23 
injury, however, has been only occasional and not extensive, and 
usually has not been considered serious. The stock is usually at- 
tacked at a scar, where the roots have been injured or cut off, or at 
a graft, as " cleft-graft " apple stock. 
At Wellington, Kans., on November 14, 1910, E. O. G. Kelly states 
that on several occasions dying and dead apple sprouts in a nursery 
had been severely burrowed. An examination of 3-year-old stock 
showed that the roots and body of a number of the trees had been 
burrowed in the same manner as the sprouts, and the termites 1 were 
in the burrows in these larger trees. About 5 per cent of the stand 
would have to be discarded on account of their ravages. The pest 
had been injurious for a number of years and was worse in dry 
years than in wet. The 3-year-old trees were quite badly damaged 
when they were put out in 1909, because the early spring was so dry. 
The 2-year-old trees were not very badly infested during the fall of 
1910. Quite a number of young sprouts were girdled, and the result 
of girdling is a dead tree. A count in three rows of the 2-year-old 
stock gave results of 8, 7, and 12 per cent, or an average of 9 sprouts 
out of every 100, infested. In the spring or 1-year-old stock the in- 
festation was quite severe. The rows near the hedge fence were 
15 to 30 per cent infested; out farther, from 6 to 70 per cent were 
infested. The severe infestation ran in local spots, not being general 
over the field, but there were infested plants in all parts of the field 
(PI. XI). An adjoining cornfield was badly infested, numbers of 
stalks being bored by them. Some of the trees were full of the in- 
sects, while some had been abandoned. On November 26 the termites 
were still active and burrowing in the apple sprouts. Peach sprouts 
and shade-tree sprouts in the same nursery were injured. 
Herrick states that in Mississippi, in a pecan nursery where there 
was damage by termites, injury was most prevalent to seedling pecans 
of the 1-year growth. 
A. L. Quaintance, in charge of Deciduous Fruit Insect Investiga- 
tions, states that numerous reports relative to injury to pecan nursery 
trees by white ants have come from various parts of the pecan-growing 
area, as Texas, Florida, Mississippi (PI. XII), Louisiana, etc. W. B. 
Wood investigated a case of serious infestation of a pecan nursery 
in the neighborhood of Petersburg, Ya. An inspection, on October 
8, 1912, of this nursery, which consisted largely of pecan trees vary- 
ing in age from 1 to 4 years, showed that the severest injury to the 
1 Leucotermes sp. (probably lucifugus).
