A HOLT INSECTS.
[All inquiries oonoefning insects or plant dis
eases should beaooompattled by specimens,
if possible. In lending insects please ob
serve the following directions: Adult in
sects should first be killed. This can easily
and quickly be done by putting the insect
for a few momenta in a closed vessel with a
few drops of chloroform. Any method,
however, which does not mutilate the
specimens, will answer. Place the speci
mens to be sent in a stout tin or wooden
box. packing them withe >tton. so they will
not be broken. Caterpillars and other lar
val forms should be sent alive, care being
taken to put enough of the food plant in
the box to last two days. Do not punch
holes in the box. The mailing rate on pack
ages of insects or plants is 1 cent per ounce.
Accompany the specimens with your notes
and observations. Write your name plain
ly on the outside of the package, and ad
dress it to Pkok. V. V. riPBB, Pullman.
THE PEAR LEAF BLISTER MITE.
Considerable alarm has been felt
lately among- fruit growers throughout
the state owing- to the appearance of
a new disease of the pear, specimens
of which have been sent us from sev
eral localities. The trouble becomes
apparent even before the leaves are
fully unfolded, by the appearance of
several or many brig-ht red pimple-like
spots on the leaves. These spots are
usually about one-eig-hth of an inch in
diameter, and more conspicuous on the
upper side of the leaf.
At the present date they have turned
green like the rest of the leaf and are
scarcely noticeable. A little later they
will turn brownish or blackish, becom
ing thickened or corky in appearance
especially on the under side of the
This disease has long- been known to
horticulturists and is caused by the
minute mite, named above, which
causes the gall-like thickening- much
as tree galls are caused by insects.
This mite is not an insect, but is more
nearly related to the "red spider" mite;
it is exceedingly minute, being- invisi
ble to the naked eye, and appearing
merely as a speck with a g-ood lens. To
study it at all satisfactorily a good
microscope is necessary. The creature
measures about one-one hundred and
fiftieth of an inch in length, is cylin
drical in shape, and has its body mark
ed by numerous ring-like striae. It
possesses but four legs placed at the
front end of the body.
The life history of the pest is as fol
lows: The eggs are laid in the spring
by the females in the galls, which they
cause to form on the cleaves, and here
young hatch. Sooner or later they
leave these galls through a minute
opening on the under side, which can
be seen with a lens, and migrate to
new leaves, and take shelter in crev
ices on the twigs, usually beneath the
scales of the terminal buds, where
they remain through the winter.
The damage done by these mites,
while not serious is considerable. The
principal efl'ect is to interfere with the
function of the leaves, so that a less
ened supply of food is stored up by the
plant; the diseased leaves also fall
Until the last two years the only
reined)' proposed was to pick off the
diseased leaves and burn them, a ted
ious and unsatisfactory! method, or to
prune back the trees vigorously in
winter. Experiments made at the
Cornell University station in 1891 and
1892, demonstrate that the pest can be
completely exterminated by a thorough
spraying- during- the winter with ordi
nary kerosene emulsion diluted only
six times. Other insecticide substan
ces did more or less g-ood, but only the
kerosene emulsion was perfectly satis
factory, owing- undoubtedly to the fact
that the oil penetrated all crevices,
while other substances do not.
Excellent accounts of this mite are
to be found in Saraner's Plant Diseas
es (German); Cornell Experimental
Station Bulletins 23 and 61; and in the
Second Annual Report of the state en
tomologist of Illinois.
The impression seems to be abroad
among- the orchardists of the stale
that the above disease is the pear leaf
blight caused by the fungus entoinos
porium maculatum, and in at least one
case we know of Bordeaux mixture be
ing applied. This is a good remedy
for the fungus disease, but is totally
useless so far as the mite is concerned.
The fungus disease can be distinguish
ed easily by the fact that it produces
neither the corky appearance nor the
thickening that the mite does.
These little pests are even more
numerous than usual this season, and
the leaves of beets, potatoes, radishes
and cabbage, punctured with minute
holes, makes their presence and the
damage they cause easily noticeable.
They also thrive on the various pig
weeds and knotweeds.
The following are good remedies for
the pest: Paris green in the propor
tion of one ounce to ten gallons of
