put in and covered well with earth (p. 10) . A similar method of 
using tobacco stems as a preventive against the peach "borer 
( Sordino idea exitiosa ) is also described (p. 14).

Tobacco dust put at bases of trees and the earth mounded to a 
height of 6 inches gave imrnanity for the fruit year, but on trial the 
second year failed to keep out the worms of the moth Sanninoidea 
exitiosa Say (pp. 199-203).

Sprays of nicotine resinate, Scabecide, aid other insecticides 
were applied at intervals of 10 days to 2 weeks. In all cases the trees 
were uninjured but the number of larvae of the peach tree borer ( Aegeria 
(Sanninoidea.) exitiosa Say) was not materially reduced.

Nicotine resinate, used as a stomach poison, was applied as a 
spray (1:100) to the trunks of many peach trees. It disappears slowly. 
Definite tests for nicotine showed it present as long as 5 weeks after 
an application was made. This test indicates the ineffectiveness of 
nicotine resinate as a stomach poison for newly hatched peach tree 
borers ( Sanninoidea exitiosa Say) (p. 33). Nicotine resinate was also 
used as an ovicide, and as a larvicide for newly hatched larvae. It 
was not considered promising for these purposes (pp. 31-32) .
