On the next page are illustrated in full color 15 of the 
plant pests most commonly found in Southern gardens. 
Knowing them is the first step to take in completely 
controlling them. Using Staffel’s insecticides is the next. 
So study these insects. Compare them with the insects 
now maiming your plants...then kill them with Staffel’s 
reliable insecticides. 
ASPARAGUS BEETLES: Adult hibernates under rubbish, emerges in the 
spring, feeds on tender shoots and lays eggs. These hatch into gray, 
black-legged grubs which attack the leaves and stalks. The 12-spotted 
asparagus beetle is reddish brown or orange with 6 black spots on each 
wing cover. Approximately 7/32”. 
MEXICAN BEAN BEETLE: The adults hibernate in plant rubbish and 
appear about with the first bean leaves. After eating for a week or two 
they lay yellow eggs in clusters on the undersides of leaves. Repulsive yellow 
larvae covered with spines hatch in 6 to 14 days and eat all the leaves 
but the veins and upper epidermis. After three to five weeks they pupate, 
the beetles emerging about a week later. Approximately 5/16”. 
POTATO BEETLE: Both the larvae (soft, dark red with black head 
and spots) and the adults (convex hard-shelled yellow beetle with black 
stripes) feed on the foliage. 
CHINCH BUGS: Young and adult bugs puncture grass stems and suck 
juices. The leayes become red-stained and in severe infestations large 
areas of turf may turn brown. Adult bug is 1/5 inch or less but has a 
conspicuous black body with white wings; the young are reddish. If its pres- 
ence is suspected, flood a piece of lawn and watch for the bugs to climb the 
grass stems. 
CUCUMBER BEETLES: Striped cucumber beetles are overwintering yellow- 
orange black-striped adults which devour leaves and stems of tender 
young plants and may infect them with cucumber wilt. The 12-Spotted 
Cucumber Beetle is a more serious menace in the South. 
CORN EAR WORM: Begins to injure plants when the ears are in silk, 
continuing active until harvest time. Its presence is evidenced outside 
by moist castings on the silk; inside the husk the grains may be eaten down 
to the cob; molds may follow the feeding of the larvae. 
OYSTER SHELL SCALE: Insect pest which attacks various shrubs and 
trees; so called because of the shape of the protective covering, which 
suggests an oyster shell from 1% to 1% inch long. 
SAN JOSE SCALE: Insect pest of many fruit and ornamental trees and 
shrubs, formerly considered exceedingly harmful and dangerous but now 
easily kept under control by systematic correctly planned spraying.

MEALY BUGS: White, cottony appearing insects attacking many orna- 
mental and greenhouse plants and ail citrus species. Two types: the 
citrus or short-tailed mealy, which produce living young; and the long-tailed 
mealy bugs, which have long, waxy processes resembling tails and which 
reproduce by means of eggs. These are carried by the females in cottony 
waxy sacs which are found chiefly at the axils of branching stems or leaves 
of infected plants. 
10 TOMATO HORN WORM: Exactly as illustrated. Feed on leaves and 
should be picked by hand or sprayed before the fruit sets. Adult moth 
is a mottled-gray-brown with a wingspread of 4 to 5 inches. If stems are 
infected with striped caterpillar (the common stalk borer) the only course 
is to destroy the plants and set out new ones. 
1 APHIS or APHIDS: Popularly called plant lice. Small, soft-bodied, 
they are usually green but may be brown, yellow, pink or black. Feed 
by thrusting a sharp-nosed stylet from their beaks into the plant cells and 
sucking out the sap. The plant’s resulting loss of vitality is shown by dis- 
colored areas on the foliage, curling of leaves and blighting of buds and 
fruits. Transmit plant diseases such as fire blight and mosaic. 
1 LEAF HOPPERS: Sucking insects belonging to the same order as Aphids 
and causing similar damage. Adults are small, active, slender, winged 
insects of various colors, usually found on underside of leayes and hopping or 
flying for short distances when disturbed. Certain species, particularly the 
potato leaf hopper, cause the tips of the leaves to wither and die as if they 
had been scorched, the condition being known as “‘hopperburn.”’ 
FLEA BEETLES: Small beetles which have the hind legs enlarged and 
can jump vigorously when disturbed. They injure plants by eating very 
small holes through and into the leaf so that it looks as if peppered with fine 
shot. The adults are small (1/16 to 1/5 in. long), oval in shape and yellowish 
brown or black in color. The larvae are delicate whitish, slender, cylindrical 
worms not over 1/3 in. long, with brownish heads and small legs. 
CABBAGE WORMS: Imported cabbage worm is worst offender (illustra- 
tion); riddles the first formed leaves of cabbage and cauliflower and 
destroys so much leaf tissue that the heads are stunted and do not form 
at all. The adult is the familiar white butterfly which emerges in the spring 
and lays several hundred eggs on the underside of the leaves. The cabbage 
looper attacks cabbage in the same manner, is a light green caterpillar with 
four thin lengthwise white lines; moves by humping or looping up the middle 
of the body. 
5 SQUASH BUG: Reddish-brown to black, flattened true bug 34 inch long, 
which feeds on squash, melons and other cucurbits. Leaves attacked 
by it soon wilt and become blackened and crisp. Give off a disagreeable odor 
when crushed and commonly called Stink Bugs.
