"'RST5 WITH POISONED BAITS AND ATTRACTANTS FOR
:f..S CF THE T09ACCO AND TOLATC IIORMWORMS

By L. B. Scott and Joe Milam, Division of
: ck Crop and Garden Insect Investigations


f'ior to the development of arsenical dusts for the control of the
tobacco hornworm, P.-:toparce sextet (Johan.), and the tomato hornworm,
P. qui =r, .c,,-.. Ki~'aw. .), on tobacco, partial control was obtained by
placing poisoned syrup in newly opened blossoms of the jimsonweed,
Datura stramonium L., a preferred feeding plant of the moths. This
method was moderately effective, but it necessitated treating newly
opened blooms each evinint. Later, attempts were made to obtain the
odorous principle of jimsonweed blossoms by distillation, extraction,
and enfleur, e, but with little or no success (3). Many chemicals were
tested in an effort to discover a substitute for the natural frc ^r-nce
of jimsonweed blooms, and several, including benzyl benzoate and iso-
amnyl benzoate, were attractive. Later, azyl splicylete (probably iso-
amiyl selicylate) produced a marked feeding response.

ioths attracted to the artificial odors were captured readily in
traps (2) or induced to take poisoned beibs from simulated jimsonweed
blooms, known as poison feeders (1). Laboratory tests with many poisons
indicated tht most of them were palatable to the moths but that they
killed too slowly or not at all. A 5-percent solution of tartar emetic
in sweetened water ws found to be effective and was used for a number
of years.

The authors continued these investigations and developed a safe
and rkirly effective bait containing 0.04 percent of rotenone (from
an aqueous extract of derris or cube) and 10 percent by weight of
sugar in water. Large field experiments conducted in Tennessee in
1941 and 1942 (4) demonstrated that moths -Ltracted to iso-amyl sali-
cylate r.py be trapped or poisoned in large numbers. Traps and feeders
containing poisoned bait, when placed at strategic points distributed
over square-mile areas in 1942 and 1943, materially reduced the horn-
worm infestation in fields of burley end dark fire-cured tobacco, and
their use demonstrated that either of these methods is of value as a
supplementary control.

The results of tests with different poisons and %ttrqctants for
hornworms during these investigations are presented herein. These
tests were mede ,t Cllrksville, Tenn., 1937-45.






-2-


The poisons were tested in a cloth-covered cage approximately 70
feet long, 35 feet wide, and 8 feet high, divided into six equal se,-
tions. A poison feeder and a means of diffusing the odor of iso-amil
salicylate were mounted on top of a 3-foot stake in the center of each
compartment. All baits were liquid and contained 10 percent by wei,;ht
of cane sugar in water.

The aromatic materials were tested under field conditions in t-aps,
each equipped with two poison feeders for the visual attraction of
moths and with two 1-inch vials of the material to be tested. The odors
of the materials were diffused from wicks extending into the liquids
and protruding 1 inch above the top of the vials. The wicks were hold
in position by loose-fitting corks. Each treatment was replicated three
times. Iso-amyl salicylate was purchased from several dealers, but none
of the tested brands proved to be outstandingly superior to the others.
materials that attracted very few or no moths in several days were dis-
carded, whereas those that showed promise were tested for comparatively
long periods. The variation in effectiveness of a material, as shown
by the results of several tests, is attributed to changing weather con-
ditions and fluctuations in the moth population.

Table 1 lists the poisons that were tested and gives the mortali-
ties of moths sfter 12 and 18 hours. The tests that were made at tl.e
same time were grouped, as they are more comparable than tests made at
different times.

Cube extracts prepared by the authors to contain an undetermined
percentage of rotenone are referred to as mixtures of cube with water
or other materials. The strengths of the baits containing these ex-
tracts are given as ratios of mixtures in colpun 1 to additional water
prior to the addition of sugar. These extracts were prepared from
ground cube root containing 4.28 percent of rotenone and were filtered
before use. Such expressions as "rotenone in water (extract)" refer to
extracts of cube or derris prepared either by the Division of Insecti-
cide Investigations or under its instruction to contain a known percen-
tage of rotenone. It is recognized that these extracts contained other
extractives then rotenone that may have been of value. These extra ts
were diluted on the basis of rotenone content, and the percentages of
rotenone in the liquids before the addition of sugar are given in
column 2. The preparation referred to as "rotenone (pure) in 95 percent
ethyl alcohol" was prepared by mixing an excess quantity of pure rolen-
one crystals with 95 percent ethyl alcohol. The rotenone crystals that
did not dissolve were discarded.

The results in table 1 show that rotenone is very little, if any,
more toxic than tartar emetic to the moths. The use of rotenone is
safer, however, since tartar emetic is very toxic to warm-blooded
animals.









Table 2 lists the materials tested, and gives the number of moths
caught within the indicated number of days. About half of approximately
100 materials tested were attractive, but none were more attractive
than iso-amyl salicylate.
