moth, has been very encouraging,
there being marked decrease this
year in the numbers OF both these
pests. Parasites and beetles that at
tack, these dangerous insects have
been introduced and have been large
lily instrumental in bringing about
good results. Colored posters were
prepared by the office illustrating the
gypsy moth and its natural enemies
and these we're posted in all post Of
fees and town offices in the infected
districts and copies were sent to the
oranges and public Libraries. The
campaign has also been waged by
mail and Boy Scouts who have dis
Itributed cards bearing the same IL
Illustrations.
Development Of Insecticides
A combination spray, composed of
lime sulphur, arsenate of lead, and
nicotine, has been used successfully
during the year by many orchard
growers, to control insects and fung-
Gus diseases. Other poisons to con-
troll orchard insects have been devel-
oped and are now being tested. Ar
senical sprays are being made more
practicable for use in combating cram
berry pests in New Jersey. Effec-
tive spraying has also been done in
the pecan orchards Of the SOUTH. in
terested growers aiding the depart
ment in the work. Remedies are also
being recommended and developed for
pests that endanger apple, peach and
pear orchards.
Boil WeeyiI
The boil weeyil did about $50, 000,-
900 worth of damage to the cotton
crop in 1913, as estimated in the new
report Of the entomologist. Nearly
$4,000 square miles OF new territory
became infested during the year. Ev-
cry effort is being made to control
the depredations, particularly by the
use of the powdered orthoarsenate Of
lead, and hand picking of cotton
squares and bolls. Arsenate of lead
was tried with varying results and
the question oft success under prac-
teal plantation conditions today re-
mains undecided.
