Note: The Bureau of Entomology is particularly an¬ 
xious to receive reports as to the presence of this new 
insect in orchards so that it may determine whether it 
has spread beyO'iul the region around the District of

INSECT PESTS AND PLANT DISEASES DETECTED 
BY PLANT QUARANTINE OFFICIALS 
One hundred and ninety-three different kinds of in¬ 
sects, which might prove hurtful to American crops and 
116 plant diseases of similar significance, were detected 
by State and Federal inspection during the last fiscal 
year on plants and plant products offered for import into 
the United States, according to the report of the Federal 
Horticultural Board of the U. S. Department of Agricul¬ 
ture. Of the insects, 14 were scale insects such as pear 
scale, though they range from scales found on orchids, 
cocoanut, and bamboo, to other forms found on wistaria, 
camellias, hemlocks, and pines. In addition, nests of 
the brown-tail moth, egg masses of the European tussock 
moth, pupae of the dagger moth, cocoons of the pine 
sawfly were discovered. 
SPRAYING FOR PEAR LEAF WORM 
The pear leaf worm, an insect which does considerable 
damage to pear orchards, especially on the Pacific coast, 
is easily controlled by spraying. A contact spray is 
usually effective in controlling the insect in the larval 
stage, and should be applied when the blossoming period 
is about over and two-thirds of the petals have fallen. 
The following formula for a contact spray is given in a 
new professional paper of the Bureau of Entomology, 
U. S. Department of Agriculture: Fish-oil soap, 1 
pound; water, 25 gallons; nicotine sulphate (40 per cent, 
concentrate), 1 to 1,200 parts of the spray. When the 
infestation is severe and promises destruction of the 
foliage, a poison spray, made of four pounds of lead ar¬ 
senate to 100 gallons of water, should be used. The 
best time for applying this is when the holes in the leaves 
are not larger than one-half inch in diameter.

Dr. S. B. Fracker has been appointed acting state en¬ 
tomologist until a suecessor to Professor Sanders 
is appointed. 
Dr. M. C. Tanquary, assistant professor of Entomology, 
Kansas State Agricultural College, who was granted a 
leave of absence in 1913 to accompany the Crocker Land 
Expedition has returned to the Kansas Agricultural Col¬ 
lege and will continue his work in the college and exper¬

According to a circular letter issued by the New Zea¬ 
land Association of Nurserymen there is considerable 
controversy in regard to Root Knot. The officers of the 
Agricultural Department detsroy trees so alfected, which 
does not always meet with the approval of the nursery¬ 
men. 
Nurserymen are also attempting to come to an agree¬ 
ment in regard to prices. 
Within the past ten years Australian fruit growing 
areas have increased by nearly sixty thousand acres. 
On account of the reverse seasons Australia imports 
large quantities of apples from the United States and 
Canada, but thus far the quantity of such fruit exported 
to America has been small, Europe having been the great 
market. 
The Governor of Minnesota has allowed an emergeney 
appropriation for the use of the State Entomologist for 
fighting White Pine Blister Rust in Minnesota, with the 
implied promise that more money will be available if 
neeessary. The work has been pushed vigorously dur¬ 
ing the summer. Only two localities have been found 
in which the rust exists, and most vigorous methods of 
eradication are being pushed at these places. Nurseries 
of the state have been combed for other evidences of the 
disease, but it is believed that the two localities men¬ 
tioned are the only places involved at the present time. 
The Plant Pathology Division of the Minnesota Experi¬ 
ment Station is co-operating in an advisory capacity in 
this work, as well as the Bureau of Plant Industiy, 
which is also aiding the work financially. Federal In¬ 
spector Pierce has made several trips to the state and 
taken part in various conferences. The Entomologist 
has had four to eight men in the field most of the time. 
One infection has been traced as coming directly from 
Wisconsin, which state received diseased trees from 
Germany. The source of infestation in the second lo¬ 
cality where the dis(‘ase was found, is believed to have 
been a European Nursery whose locality is not yet 
known. 
WICK’S TREE DIGGER 
I will not sell parts of my tree digger on a guarantee 
when used with the old fashioned tree digger as it has 
been proven that they pull twice as heavy as my digger. 
But I guarantee to dig as big trees as they do with the 
old fashioned digger, and only use two commorf sized 
horses, as shown on the cut in the advertisement. 
Respeetfully yours, 
Oscar Wick.
