die European pine shoot moth (Evetria huoliana), 
which was made the subject of a warning letter issued 
from the branch of Forest Insect Investigations of the 
Bureau of Entomology of this Department, October 26, 
1914, is a pest of such importance, and the likelihood of 
its entry is so great, as to lead to the serious considera¬ 
tion of issuing a quarantine prohibiting the further im¬ 
portation into the United States of foreign pines, supple¬ 
menting and extending the present quarantine, which ap¬ 
plies to all five-leaved pines from Europe and Asia.

IPSY AND BROWN-TAIL MOTHS DECREASING 
A marked decrease in the numbers of both the gipsy 
and brown-tail moths is declared by the Bureau of En¬ 
tomology of the U. S. Department of Agriculture to have 
taken place in the period covered by the report which has 
recently been published of its work for the year ending 
June 30, 1914. This has been largely brought about by 
the wilt disease and the parasites and other natural 
enemies of these pests, which have been introduced to 
fight them. 
An entomologist of the Department of Agriculture w 
ad seen Mexicans add cactus to whitewash in order to 
make it stick to boards, derived from this the idea that 
cactus solution would make arsenical sprays for killing 
insects adhere to plants and thus protect the plants 
against insect ravages for a longer period. As the result 
of a series of experiments with the ordinary "prickly 
pear” or (Opuntia lindheimeri) Engelm, which is plenti¬ 
ful in the Southwest, it has been found that if sliced 
prickly pears or indeed any other cactus ol sufficient size 
are added to the water before the zinc arsenite or Paris 
green and the lime are put in, the mixture will stick to the
