often eating into tomatoes and string beans when it is present in 
large numbers. 
The eggs are laid upon the tassels, silk and leaves of the corn 
and the little worms burrow their way into the ears of corn and 
are most commonly found near the tips of the ears. 
There are several broods a year in the Southern States, and 
in Colorado the worms are found throughout the summer. 
Remedies .—There is no satisfactory remedy for the control 
of this insect. Probably the best one for the garden is to destroy 
the worms by hand as they eat into the ears o'f corn. Po.sonous 
sprays are of very little effect and are dangerous, as they render 
the corn fodder unfit for stock food. 
CABBAGE AND CAULIFLOWER. 
Green Cabbage Worm (Pieris rapae). 
Cabbage, cauliflower and allied plants are nearly always seri¬ 
ously attacked in Colorado by the common green cabbage worm, 
which feeds upon the cabbage leaves, and, when abundant, often 
eats deeply into the cabbage heads, ruining them for market. 
The adult insect is a white butterfly, which deposits its eggs, 
one in a place, upon the leaves of the plants attacked. If one w.ll 
watch these butterflies over a cabbage patch, it will be no trouble 
to notice the butterflies occasionally descending and touching the 
tip of the abdomen to a leaf. In doing this an egg is deposited. 
The eggs hatch in a few days and the little worms begin at once 
to feed upon the leaves near where they hatch. 
Remedies .—One of the most efficient remedies for this insect 
is the use of arsenical poisons. Perhaps the most satisfactory one 
to use is Paris green, though arsenate of lead may be used with 
satisfactory results. One of the best methods of applying the Paris 
green is to mix a teaspoonful of the poison in about one pint of 
common wheat flour and then dust the mixture over the infested 
plants through a cheese cloth sack. The application is best made 
early in the morning when there is no wind and when a little dew 
is still upon the leaves. A very light dusting is all that is necessary 
for good results. If arsenate of lead is used, dilute one pound of 
the lead paste, or one-half pound of powdered lead, in twenty gal¬ 
lons of water and thoroughly spray the leaves. The application 
should be begun as soon as the butterflies begin to deposit their 
eggs, and should be repeated once every week or ten days until the 
cabbages are nearly grown. 
Insect powder, or Pyrethrum, may be used either in the form 
of a spray, one ounce to three gallons of water, or may be lightly 
dusted over the infested plants for the destruction of the worms.
