Insects of Commercial Importance in Florida— 
Their Identification and Control 
Insecticidal dusts or sprays marked * should be used with caution because of possible residue problems involved. See page 50 
for a guide in applying such materials. Bars accompanying each illustration indicate approximate sizes of insects. 

Winged Adult 
Wingless Adult 
APHID. The most common species are usually colored green, 
powdery gray, brown or black. The size of the different species 
vary, the pea aphid being the largest of the group. Aphids 
attack all important vegetable crops in Florida. 
DUST RECOMMENDATIONS 
For the control of pea aphids: 
Rotenone Dust—1%. 
For the control of arhids on other crops: 
Nicotine Dusts—3 or 4% Activated. 
Black Leaf 10—Nicctine Dust.. 
Pyrocide Dust No. 74. 
SPRAY RECOMMENDATIONS 
For the control of aphids on potatoes: 
50% wettable DDT powder—2 pounds per 100 gallons. 
For the control of aphids on other crops: 
Black Leaf 40—1:400.

Adult Nymph 
THRIPS. The adults are usually yellowish, brown or black. 
Crops frequently attacked include tomatoes, peppers, egg plant, 
beans, peas, onions, celery, and occasionally all cole crops. In 
some varieties of beans, their feeding is largely responsible for 
the premature dropping or shedding of blooms. 
DUST RECOMMENDATIONS 
Kilcide 3 Dust (Contains 3% DDT) .* 
Black Leaf 10—Nicotine Dust. 
Pyrocide Dust No. 7%. 
SPRAY RECOMMENDATIONS 
50% wettable DDT powder—2 pounds per 100 gallons.* 

Nymph 
BEAN LEAF HOPPER. Both adults and nymphs are pale 
green in color. The adults, when flying, appear to be whitish. 
In Florida, these insects confine their feeding almost entirely 
to snap, lima and pole beans. 
DUST RECOMMENDATIONS 
Kilcide 3—Sulphur Dust (Contains 3% DDT).* 
Pyrocide Dust No. 5-A. 
Pyrocide Dust No. 7%. 

Nymph 
CHINCH BUG. The body of the adult is black or dark gray. 
The wings are white and therefore conspicuous. Each wing 
has a single black spot. There are two forms of adults, one 
having full-sized wings, while the other has short wings, which 
do not cover the lower portion of the abdomen. The tiny, newly- 
hatched nymphs are bright pink, later changing to a dark, dirty 
red. 
DUST RECOMMENDATIONS 
For the control of chinch bugs in lawns: 
Saba-Chinch. 
Treat infested spots only at the rate of 4 pounds per 100 square 
feet. Sprinkling or rain following an application will not 
affect control.
