LIEFGREEN’S GUIDE FOR INSECT PESTS 
OF THE FARM, GARDEN 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 
;.n insect belongs before one can take reme¬ 
dial measures against it. Roughly there are 
two classes: the chewing and the sucking in¬ 
sects. 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 Arsen¬ 
ate, 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. 
COMMON INSECTS IN THE VEGETABLE 
GARDEN 
On Beans: 
Mexican Bean Beetle: 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. 
Thrips : Very small, lice-like insects, yellow or brown or black. Work in 
the flowers 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 aphis. Use a Nicotine or pyrethrum dust or spray. 
Cabbage Butterfly: The worms of this butterfly that feed on cabbage 
and Cauliflower and related plants are soft, smooth, green caterpillars, 
that sometimes are especially injurious. Two pounds Lead Arsenate, two 
pounds Fish-oil Soap in 50 gallons of water is a recommended spray. Or 
dust with one pound Lead Arsenate mixed with five pounds hydrated Lime 
or 2 pounds of Dutox to 5 pounds of Talc. Do not use Dutox with Lime. 
We also recommend Fluocide—( a ready mixture). 
Diamond Black Moth —A small worm about one-lialf 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 fish oil soap for 
a spreader. 
On Cantaloupes: 
The Twelve-spotted Cucumber Beetle: A green insect one-fourth of an 
inch long with twelve 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 Striped Cucumber Beetle: This beetle is also about one-fourth of 
an inch in length, but is yellow' with three black stripes. It feeds like the 
Twelve-spotted Cucumber Beetle and the control is the same. Heretofore, 
trying to kill them with the ordinary poisons has been unsucessful; 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 
injurious to cantaloupes. A fresh Nico-Dust of 2 y 2 per cent Nicotine 
strength, or a pyrethrum compound Dust, carefully applied, is the best. 
On Corn: 
Corn Ear Worm: This is a very difficult pest to control, but good suc¬ 
cess 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 meas¬ 
ures are the same.
