Liefgreen's Guide for Insect Pests of the 
Form, Carden and Home 
The insects which injure plants in the 
garden or field have different methods of 
doing their damage, and it is necessary 
to know to which class an Insect belongs 
before one can take remedial measures 
against it. Roughly there are two classes 
- — the chewing and the sucking Insects. 
When a person is suspicious that Insects 
are injuring a plant it should be first 
examined to determine which type or 
class is present. 
If actual portions of the plant are 
eaten, the chewing type of insect is 
guilty and one of the arsenical poisons 
should be used, such as Lead Arsenate. 
Paris Green, etc. 
When no material part of the plant is 
removed, but the leaves or stems show 
speckled, whitish and brown or yellow 
areas, the sucking type is very apt to 
be injuring the plant. Insecticides such 
as Nicotine and Pyrethrum sprays and 
dusts which kill by coming in contact 
with the body of the bugs are necessary 
to use for this type. 
Insects in the 
Vegetable Garden 
on BEAnS 
MEXICAN BEAN BEETEE — A yellow 
beetle almost one-fourth of an inch long, 
with sixteen black spots on the back. 
Young work on the underside of the 
leaves. Use Sodium Fluosilicate and 
Lime. 
THBIFS — Very small, lice-like insects, 
yellow, brown or black. Work in the 
fiowers or on the leaves, where they 
make shiny whitened areas. Use Tobacco 
or Pyrethrum compounds as a spray or 
dust when on leaves or flowers. 
ON CABBAGE 
APHIS — A gray-green plant louse. Use 
Nicotine or Pyrethrum dust or spray. 
CABBAGE BUTTEBPLY — The worms 
of this butterfly that feed on cabbage 
and cauliflower and related plants are 
soft, smooth, green caterpillars that are 
sometimes especially injurious. Two 
pounds Lead Arsenate, two pounds Fish- 
Oil Soap in 50 gallons of water is a rec¬ 
ommended spray. Or dust with one pound 
Lead Arsenate mixed with five pounds 
hydrated Lime or two pounds of Dutox 
to five pounds of Talc. Do not use Dutox 
with Lime. We also recommend Fluoclde 
(a ready mixture and non-arsenical). 
DIAMOND BEACH MOTH — A small 
worm about one-half inch long which 
feeds on cabbage and cauliflower, eating 
small holes in the leaves and spinning 
small white cacoons on the leaves. Spray 
with Black Leaf 40, using 1 pint to 75 
gallons of water with 3 or 4 pounds of 
fish-oil soap for a spreader. 
ON CANTAEOUPES 
THE TWEEVE-SPOTTED CUCTJMBEB 
BEETEE —A green insect one-fourth 
inch long with 12 black spots on the 
back. This insect damages all parts of 
the vine, the young live in the ground 
and are Injurious to the roots. Control 
the adults with Sodium Fluosilicate and 
Lime. 
THE STBIFED CUCUMBEH BEETEE 
—This beetle is also about one-fourth 
inch in length, but is yellow with three 
black stripes. It feeds like the 12-spotted 
Cucumber Beetle and the control is the 
same. Heretofore, trying to kill them 
with the ordinary poisons has been un¬ 
successful; but the Sodium Compound 
or Dutox, when properly applied, will 
get nearly a complete kill. 
APHIS —The melon aphis is a small, 
soft, green plant louse that is very in¬ 
jurious to cantaloupes. A fresh Nico- 
Dust of 2% per cent Nicotine strength, 
or a Pyrethrum compound dust, care¬ 
fully applied, is the best. 
ON COHN 
COBN EAR WORM —This is a very dif¬ 
ficult pest to control, but good success is 
possible on sweet corn by dusting with 
Lead Arsenate every seven days when 
the corn is in the silk. 
ON CUCUMBERS 
The same pests attack cucumbers as 
cantaloupes, and the control measures 
are the same. 
ON EETTUCE 
CUTWORMS —Several different kinds of 
cutworms attack lettuce. The majority 
of them can be controlled by the use of 
a poison bait especially formulated for 
cutworms. 
GRASSHOPPERS —For grasshoppers at¬ 
tacking lettuce, use the standard grass¬ 
hopper poison bran bait. See us for the 
formula. 
ON MEEONS 
The insects found attacking canta¬ 
loupes are also enemies of melons and 
the same methods and poisons should be 
used against them. 
ON ONIONS 
THRIPS — This is the worst pest of 
onions. It is a very small, louse-like in¬ 
sect, light yellowish in color, that feeds 
down between the leaves causing them 
to turn white. It is difficult to control 
successfully, but very good results can 
be obtained by fumigating with Calcium 
Cyanide or NIco-Dust under long hoods 
that are dragged over the rows. 
ON PEAS 
PEA APHIS —A large green plant louse. 
Use a contact insecticide when they first 
appear on the plants, repeating every 
ten days until controlled or all peas have 
been harvested. 
ON POTATOES 
COEORADO POTATO BEETEE —A large 
beetle, yellow with black stripes. The 
young are orange yellow. Use 2 pounds 
Lead Arsenate in 50 gallons of water. 
ON SPINACH 
PEEA BEETEES — These are small, 
shiny black beetles that fly rapidly when 
disturbed. Because of the danger of poi- 
46 
soning, the arsenicals cannot be used, 
and it is necessary to treat with a very 
strong contact insecticide such as the 
Nicotine or Pyrethrum compounds. 
Common Insects 
in the Home 
ANTS — For the small black or red ant 
that infests the house and gets into the 
refrigerator, sink, etc., bait by setting 
out Antrol. This has proved 100 per cent 
effective where tried and is the cleanest 
and simplest of methods. 
COCKROACHES — Spread Sodium Fluor¬ 
ide or Sodium Fluosilicate about where 
the roaches are in the habit of traveling. 
This will rid the house of them in less 
than a week. 
TERMITES — For information on con¬ 
trol call us or write to the State Ento¬ 
mologist, the University of Arizona or 
the County Agricultural Agent. 
Common Insects 
in the Flower Garden 
ANTS — The large red Harvester Ant will 
attack almost every living thing grow¬ 
ing near its nest, besides being trouble¬ 
some because of its bite and sting. Cal¬ 
cium Cyanide is the best poison to use 
in the control of this pest. Use four to 
five tablespoonfuls per nest, digging a 
hole in the center of the mound 16 to 18 
inches deep and placing the Cyanide in 
the bottom and covering over tightly 
with soil, as the gas is lighter than air. 
APHIS OB PEANT EICE — There are 
many kinds of aphis that injure flowers 
in the garden. They may be reddish, 
green or black, and be with or without 
wings. Roses, Stock, and Sweet Peas are 
especially subject to attack. Control with 
a Nicotine or Pyrethrum spray or dust. 
CUTWORMS — They attack many young 
plants in the Spring and early Summer. 
If the plant is cut off at the surface of 
the ground or the roots eaten, put out 
the cutworm bait, scattering it thinly 
along the rows affected. There are some 
cutworms, however, that climb the plants 
at night, eating the leaves. For this in¬ 
sect, spray or dust with Lead Arsenate, 
Calcium Arsenate, Dutox or Fluoclde. 
EACEWING BUG — This is an especial 
pest of Hollyhocks. It works on the 
under sides of the leaves, turning them 
a brown or yellow color. Spray with a 
Nicotine or Pyrethrum compound, tak¬ 
ing pains to get the poison on the under 
side of the leaves. 
THRIPS — This Insect bothers roses, par¬ 
ticularly in the Spring. Spray thoroughly 
with a Nicotine or Pyrethrum spray. 
GRASSHOPPERS— These are especially 
injurious to Zinnias in late Summer and 
Fall. Use the poison bran bait.
