| - OAAss' ANAA~yS SAlSl vi
TIE United States Entomoloei-
cal Commission, has issued the
following circular for the infor-
nation of those who may he
willing to assist the commission
in it's work, as to those employ
Ell by the commissions:
Dear Sr-Con eress at it's late
session made an appropriation
to the United States Entomolo-
gical Commission for tie COM
pletion of the Investigation into
the habits and best means of
counteracting the injuries of the
Rocky Mountain locust and Of
the cotton worm. The work on
last named insect has been con-
signed to me, and as many Of
the questions relating to the
cotton worm were pretty fully
considered during the past year,
as Indicated in the preliminary
summary of work giving; in bull
letin No. 3 of the commission,
it is my desire to pay special at
tention the present year to fur
ther study ofthe practical qnes-
lions involved in the investiga-
ton. 1t is my intention to is
sue at the close Of the fiscal
year a final and, as far as posi-
Die, exhaustive report on all in
,sects injuriously affecting the
cotton plant, SO as to embody
not only the unpublished data
collected the past year relating
to other insects then Azetiu, but
all that will be ascertail:ed dur
ing the present fiscal year re-
garding the cotton worm, which
outranks all the others in i'm
portance. [ therefore give be-
low, for the benefit ofthose en-
ployed by the commission (but
also for those who in any way
may desire to aidit in it's work),
an outline Of the plan of the
final report it is intended to
make.
The report will be divided
into SIX main parts, as follaws:
I. INSECTS AFFECTING THE ROOT,
Under this head there is need
of much further investigation,
and [ wish observers to pay
particular attention to plants
that die where the trouble
seems to be in the root. Speci-
mems found On suchroOts should
be carefully packed and sent to
me according to suggestions in
the latter of instructions. All
symptams and manifestations
should be carefully noted.
IL. INSECTS AFFECTING THE STEM AND
BRANCHES
Here, also, there is room for
additional observation, and |
repeat the request made in the
preceding paragraph.
III. INSECTS AFFECTING THE LEAF.
These include a large number
ofspecies which lave already
been studied by the commission.
1t is upon the cotton worm
among them that | desire the
recipients of this circular to con-
centrate their attention, and cs-
pecially to the means of des-
troying it. In addition to the
special instructions you will re-
ceive, the different substance
treated Of in bulletin No. 3 Of
thecommission, especially Pyre-
thr1m powder and yeast fer
ment or beer mash, should be
carefully tested so far as oppor-
tunlty offers to test them, and
result duly recorded and report
ed. Extracts from any other
plants that grow in your neigh
bOrhoOd that are not too rare
and that gives the least promise
OF beneficial result should be
made, and their effects fully
tested both upon the worms di-
rectly, npon the CD, ysalincs,
and upon the eggs; also in how
far they prevent the parent
moth from laying eggs. 1 also
desire to havetrials made of any
machine employed in your vi
entity whether for sprinkling,
spraying OF powdering; also
models or photographs, with
full descriptions of any machine
