about 2/3 this width. Its back is high and rounded giving it an oval outline. Ten 
black stripes run lengthwise over its hard, yellow wing covers. Head is splotched 
spots against a yellow background. Chew leaves ragged, most of the damage being 
done by the brick-red, black-spotted, soft-skinned, humpbecked worm stage. TREATMENT: 
Thorough spraying with STAFFEL’S 5% CHLORDANE DUST gives excellent control. Par- 
ticular care should be given to the under side of leaves and vines. Apply when either beetles 
or laryae are seen on the plants. 
; COLORADO POTATO BEETLE. Adult beetle slightly less than ¥ inch long and 
Icng, and %4 inch thick. Its body is white, thick, and wrinkled, with 3 pair of short 
hair-like legs in front, and 5 pairs of even shorter legs toward the tail end. First evi- 
dence of injury is the wilting of entire plant, often followed by death. Careful split- 
ting open of a wilted vine will reveal cn accumulation of dirty particles, greenish in color. 
Frash is moist and slimy. Entire stem usually rotted. TREATMENT: Best treatment is to 
carefully split stem lengthwise where greenish excrement indicates presence of borer. Kill the 
borer, and immediatly cover the stem with moist earth. Burn old vines as soon as crop is 
harvested. Dusts cnd sprays are effective only against eggs. Spray with STAFFEL’S SAFE- 
S-PRAY, wetting thorcughly stems and leaf‘ stalks. 
7 SQUASH VINE BORER. The larva, or borer, is a brown-headed caterpillar 1 inch 
Has offensive odor. Commonly called ‘Stink Bug.’’ Nymphs are white, haye black 
legs. Range from 3/16 to ¥2 inch. They attack plants as soon as they come up, 
puncturing the tissues of leayes and petioles, and sucking the sap, causing leaves to 
wilt, turn black, crinkle and die. The dark, flat-backed, odoriferous bugs are found in 
clusters hiding under leaves or clumps of dirt at the base of plant. Egg clusters usually 
found on the underside of leaves placed in the angle formed by leaf veins. TREATMENT: 
Dust with STAFFEL’S PYROCIDE DUST once a week. Apply dust with great care, thoroughly 
covering ALL of foliage. Only the insects actually hit with the dust will die. Hand collecting 
and killing will help. 
8 SQUASH BUG. Range from dark brown to black. Flat-backed, about 3g inch long. 
yellow strips down the back. Very active when disturbed. Gouge out leaves and stems 
with huge irregular holes. Sometimes the growing tips are completely cut off. Stems 
of plants often eaten entirely cround (girdled) by the feeding of so many beetles. 
TREATMENT: Spray with STAFFEL’S SAFE-S-PRAY, a highly concentrated Rotenone-pyre- 
thrum combination ideai for such control. Apply when beeties are seen on plants. 
9 STRIPED CUCUMBER BEETLE. A black beetle about 1/5 inch long with prominent 
lice.’ Whitish-green, black, pink, yellow or yellow-green in color, they are 
about the size of a pinhead, except for the Potato Aphid which is about 
inch long. Usually found clustered in large masses on the leaves. Soft-bodied. 
They suck the sap from leaves and stems. Leaves curl and wilt, turn yellow, crinkle and 
die. TREATMENT Spray with STAFFEL‘S NEW GARDEN SPRAY or dust with STAFFEL’S 
TRIO, the 3-WAY GARDEN PEST KILLER. Application must be extremely thorough. Aphids 
must be killed by contact. Dust under all lecyes and into all leaf crevices. 
10 APHIDS or APHIS. Attack all plant life. Commonly known as “plant 
black or yellow. Also known as “eqlico back” and ‘‘fire bug.’’ Plants wilt, 
turn brown and die. Several sizes cf these red and black-spotted bugs are 
usually found over the entire plant. Masses of tiny white eggs may be found 
on the underside of the leaves. TREATMENT: These bugs must be actually hit by a con- 
tact poison to be killed. STAFFEL’S HEMIPTERA (Sabadillo) DUST or STAFFEL’S SAFE- 
S-PRAY are effective control agents if used generously and on both sides of the leaves. 
The young are more easily killed than the adults so it is important that control begins at 
the first sign of infestation.
