In September 1936 the Bureau of Etomolgy and Plt Quarantine
of the United States Department of Agriculture issued Part II of."A
Bibliography of Nicotine" under the subitle The Insecticidal Uses of
Nicotine and Tobacco," by N. E. tcIndoo, R. C, Roark, and
This Part II was issued as E-392, a mimeographed irular of28 pages
in three sections, containing 2,497 abstracts, hich include thepublished
information from 1690 to the fall of 194. In trying to compress the most
important data contained in the original 628 pages into this brief sum-
mary, the writer had a difficult task, chiefly because much of the
mation was fragmentary and contradictory, "and the information on a
species was often widely scattered under two or three different scienifi

In the present summary the information on the most important
species that had been controlled more or less successfully before
by the use of nicotine is stated as briefly as possible. Nicotine

by orders, families, andspecies The unversed reader might inf
this large list of insects that nicotine is a universal inse cide and
that it is the most effective means of controlling the majority of
species discussed. To the contrary, nicotine has a liited use and plays
a minor part in the control of many of the species mentioned in this
review. Prior to 1934 nicotine was the best remedy kw for cer
species, but' more recently other insecticides, particularly oil sprays
and rotenone, have taken that place. To emphasize the importance of the
species mentioned, the present circular includes the geog~ic
bution of many of them, the contries being arranged in the ol
order of the references.



Insecticides are generally divided into three classe, based on
the vway they are applied to the insects. The contact insecticides co
prise both liquids and solids. In the literature on nicotine theliqi
are described as washes, tobacco water, infusions, decoctions,obacco
juice, extracts, and dips; and the solids, as poiders and dusts. T
fumigants are called smokes, fumes, or vapors, and are produed b
burning or heating tobacco in solid or liquid form. When the liqui

ta poisons, Tobaco and nicotine are used chiefly as contact insecti-
an and very little as stomach poisons.

later it was frequently used.


In 1773 tobacco was put in an iron pipe vhich was heated and the
smo it as bloiwn onto infested plants by the use of a bellows.
Stype of uigating bellows was used and described in the same year.
S pair of bellows was used to force smoke under a tent which had

Nicotine Compounds

From 1900 to 1934, 15 nicotine compounds or salts were prepa
used, and since 1934 several others have been added to the list,
these a're not to be considered here. The 5, ith dates
occur in the abstracts or could be found in notes and the orig l ler
are as follows: Nicotino sulfate (1900); acetat, lactate itate a
trichloroacetato (1913); resinate (1917); oeate, paitt a

Aphids on other flowers.--Four aphids infesting other flowers wre
easily controlled with nicotine. They were on the leaves and bulb

Jumping Plant Lice (Psyllidae)

Apple sucker.--The apple sucker (Psyll mali (Schmb.)) h b
trolled vith nicotine since 1913. It was treated in Genany, Russ
England, Norvmay, Ireland, Denmark, Nova Scotia, Sweden, zechosol ia
Finland, and Switzerland. The common method was to spray with nicot
tobacco extract plus soap. In Russia it was successfully controlled
fumigating orchards with tobacco dust mixed with straw.

Seven other psyllids have'been controlled with nicotine, but these
species are not economically important.

Leafhoppers (Cicadellidae)

Potato leafhopper.--This insect, 2ripoasca fabae (Harr.), is also known
as the apple leafhopper or bean leafhopper ad as the potato jassid. It has
been treated with nicotine since 1908 in the United States and Canada. In
most instances nicotine sulfate as either spray or dust was recomended as a
satisfactory control, but in a few instances it was inefficient or was not
so good as bordeaux mixture, vhich acted as a repellent.

Grape leahoppers Those leafhoppers, Eryhroneur comas (Say) and
ela fom wr roated th nicotine in the United S T nd Canada.
in 1828 tobacco juice was only partially effective and a tobacco fumiga-
tion tent on Theels to go over the grapevine trellis was recommended as
effective, but was soon discarded as impracticable in vineyards. A more
serious attempt to control these leafhoppers was begun in 1910. The nymphs
are easily killed ith nicotine, but in order to control the adults the
dosages must be vry strong. Black Leaf 40 vith soap, bordeaux mixture,
or other substances added to the sprays were used. Nicotine dusts, if
unustally strong (7.5 or 10 percent), vere generally efficient.

Rose leafhopper.--This jassid, ypilocyba rosae (L.), was treated
I~n, the i.te a Switzerl d, Canaa, and Czechoslovakia.
It was controlled by using nicotine with soap, Black Leaf 40, and nicotine

Other leafhoppers.--About tywo dozen other leafhoppers have been
controlled with nicotine. The most important of these appears to have
been the Thite apple leafhoppor (Typhlocjba pomaria McAtee).

Malybugs, Scale Insects, and Coccids (Coccidae)

Citrus meabu.-This coccid, Pseudococcus citri (Risso), has been
treated ith nicotine-since 19011 in the United States, Uganda, Grenada,
Russia, Bermuda, and the Philippine Islands. Tobacco dust was inefficient
and tobacco extract gave indifferent results. Black Leaf 40 and nicotine
were usually effective, but other control methods were available.

San Jose scale.--This scale insect, Aspidiotus perniciosus Comst.,
has been treated with nicotine since 1901 in Queensland, the United States,
India, and Fungary. Nicotine with soap, lime-sulfur, or an oil was usually
-effective against the i mature scales.

Oystershell scale.--Nicotine sulfate. with soap or lime-sulfur has
been ue sccessfully since 1916 against the young of the oystershell scale

Other coccids.--About 42 other species of coccids were tested with
nicotine, and it was found effective against all but 4. The best spray or
dipping solution Ywas kerosene emulsion containing nicotine.

Species Belonging to Other Fmilies of Hoptera

Whiteflies..--Seven species of' Aleyrodidae w ested wi

Other species.--Thirteen species of the Cicadida.e, Flgoridae
Cercopidae, and Mmbracidae were treated with nicotine, It wa e e
against a cicada, 4 fulgorids, 3 froghoppers, and I treehopper.


Leaf Bugs, or Capsids (Miridae)

Appile redbug,--Nicotine has been used against Lyia
since 1911, vwhen sprays containing Black Leaf (1 part to 65),Ni
(1 to 700), and Black Leaf 40 (1 to 816) were found effeotive. Thi
as well as other capsids, is difficult to control, and nicotine is e
only against the nymphs. Sprays containing 40-pernt nicotine sufate
( to 800) and soap or lie-sulfur usually gave good control A
nicotine dust was also said to have boon officient, This imor
species was treated in No.r York, Ohio, Connectict, PennsylvanianNova

Tarnished plant bugs -These species, L s oblineatus (S)
L. pratensis (L.), havy been treated .ith nicotine since 1915 in C
the United States, Germany, and England. Nicotine in various fons a

a 5-percent nicotine dust and a nicotine sulfate spray (1 to 200) plus soap
were used.

having been better than nicotine sprays.

Apple capsid bug.-Since 1916 Plesiocori ru icllis (Fall.)
been controlled with nicotine (usually 98 percet plus soap in Englan

Other capsids.--According to the literature nicotine was used
a small scale against 32 other capsids. Eight of these species be
the genus Lygu, one of which, gu pabulnus (L), sm to be
importnmt economic species, for it was treated with nicotne in Ireland
Denmark, England, and Germany.

Tobacco products were tried against numerous species of Dipteraand
the use of nicotine gave a good degree of control but was not found

Codliy moth.-Nicotine vas. first tried in '1897against the codling
mh Caoapsa Ipomonella (L.)), which i a serious post wherever apple
rees are gron Frm this year up to October 1934, inclusive, 133 abstracts
n pertain to the use of nicotine against this moth, although
ie n i wa often usd in an arsenical spray mixture primarily to con-
r ortain bugs. In 1916 nricotine sulfate was reported in
Sta to have been as efficient as lead arsenate. This report
ed nsiderable experimental work to be dono during the next 12 years.
e Washingtn entomologists still claimed that nicotine sulfate could
Sud as a substitute for load arsenato in the second and third cover spray,
though this ombination'was somewhat loss effective.

icotine in combination with oil emulsion was apparently first tried
t te codling moth in 128, There are 70 abstracts which discuss this
o ntion. It was generally agreed that nicotine sulfate combined with
-il emulsion as a good substitute for lead arsenate, The following
t t give some of the details: In 1929 and 1930 this combination proved
a effcve as the arsenate. The combination of oil (1 to 100) and nico-
ulfate (1/2 pint to 100 gallons) gave'a control of the codling moth
qual to t of 1 pound of lead arsenate to 50 gallons of vater. In 1931
erts from nie investigators wrere compred. Some said that the oil-
ctine combination gave results equal to those obtained with lead arsenate,
hle others did not get such good results. It was as effective as the
rsnate in preventing entry into the fruit and was decidedly more effective
n the arsenate in preventing "stings." In 1932 the nicotine-oil spray
ed both ovicidal and larvicidal properties for the codling moth and
ontrolled aphids and ites. This combination, used for several years
te late cover sprays, aliays gave excellent results which were approxi-
equal to those of lead arsenate. In 1933 the trend of results
lhy favored lead arsenate. 1n 1934 the consensus of opinion was that
ed sonate was superior, but nicotino-oil was vory close to it and was
most promising substitute.

There is 1 abstract about nicotine bentonite, 2 about nicotine dust,
about nicotine oleate, and 25 about nicotine tannate, The last gave
xtmely variable results, ranging from no good or not satisfactory to
t than lead arsenate for use against the codling moth,

Qther moths.--Nicotine .as tried against other moths..and it was
ctie gaiit many of them but was rarely recommended as a control
Iecus there were usually other better and more economical insecticides.


d spiders.--The common red spiders (Tetranychus spp.) have been con-
lledie with nicotine combined with other materials such as oil,
tro soap, or lime-sulfur. They were treated in Germany, Switzerland,
oh Australia, the United States, Argentina, England, Canada, Russia,
and Italy.

uropean red mite.-- This species, Paratetranychus pilosus (C. & F.),
as sccessfuly treated in most instances with nicotine in Sweden, Denmark,
h nited States, and Englazid, but the nicotine was added to other materials.
