INSECTS OF COMMERCIAL IMPORTANCE IN FLORIDA— 
THEIR IDENTIFICATION AND CONTROL (Continued ) 

Adult Larva 
COLORADO POTATO BEETLE. The yellow and_ black 
stripped “potato bug” as well as the soft brick-red and black- 
spotted humpback larva is too well known to farmers through- 
out the United States to require any further description. 
DUST RECOMMENDATIONS 
Kilcide 3 Dust (Contains 3% DDT).* 
SPRAY RECOMMENDATIONS 
50% wettable DDT powder—2 pounds per 100 gallons. 

PEPPER WEEVIL. The adult is shining, brownish black in 
color. Except for the snout, the body is covered with gray or 
yellowish scale-like hairs. The whitish larvae resemble grubs 
in appearance. The pepper weevil is most abundant in Manatee 
and Hillsborough counties, but has also been of some concern 
to growers in other portions of the State. Complete destruction 
of heavily infested fields immediately after picking is of the 
utmost importance. 
DUST RECOMMENDATIONS 
Kilcide 3 Dust (Contains 3% DDT) .* 
Kryocide Dust 30-70.* 
SPRAY RECOMMENDATIONS 
50% wettable DDT powder—2 pounds per 100 gallons.* 
Kryocide—4 pounds per 100 gallons.* 

Larva 
TOMATO PINWCRM. The moth resembles the clothes moth 
in color and appearance. When extremely young, the larvae 
are light-colored, the head being dark brown. Later they de- 
velop a dark-colored pattern, ranging from light orange to 
brownish, gradually darkening to dark gray or purplish black. 
At this stage, the background becomes greenish or green-blue. 
The larvae are a serious pest to tomatoes and eggplant in the 
field as well as in seedbeds. 
DUST RECOMMENDATIONS 
Kilcide 3 Dust (Contains 3% DDT).* 
Kryocide Dust 30-70.* 
SPRAY RECOMMENDATIONS 
50% wettable DDT powder—2 pounds per 100 gallons.* 
Kryocide—4 pounds per 100 gallons.*

Larva 
CORN EARWORM (TOMATO FRUITWORM). The 
moth is colored with shades of cream, or light brown, and with 
olive-green tints, sometimes with black dots. The larva, when 
first hatched is creamy white with a black head. The older 
larvae are variedly colored, some being solidly green, cream or 
yellow. They are usually marked with stripes and dots of two or 
more colors. The corn earworm prefers corn to other crops, 
but it is often a very serious pest in tomatoes. When corn is not 
available, they will readily attack peppers, eggplant and the 
pods of beans. 
RECOMMENDATIONS (For Corn) 
Dusting or spraying for the control of the corn earworm is of 
very little or no value. The U. S. Department of Agriculture 
(U. S. Dept. Agr. Bureau Entomology and Plant Quarantine, 
E-497, Feb. 1940) recommends the use of a solution of pyre- 
thrins in highly refined mineral oil as the most effective method 
of control. For the treatment of sweet corn in Florida, such 
solutions should not contain pine oil. The most effective and 
economical method of applying this solution is by means of a 
pressure oiler equipped with a long spout and connected to a 
knapsack tank by an oil resistant hose. The solution should not 
be applied until the ears have been fertilized, that is, as soon 
as the silks become wilted but not earlier than the third day 
after silk exposure. Applications are usually most successful 
when made between the time when the silks have wilted and 
the time when their tips have turned brown. Write us for fur- 
ther information regarding this type of material. 
RECOMMENDATIONS (For Tomatoes) 
DUSTS 
Kilcide 3 Dust (Contains 3% DDT).* 
Kryocide Dust 30-70.* 
SPRAYS 
50% wettable DDT powder—2 pounds per 100 gallons.* 
Kryocide—4: pounds per 100 gallons.* 

Adult 
MOLE CRICKET. Every grower is thoroughly familiar with 
these brown, flat insects. Their greatly enlarged front legs are 
fitted for burrowing in the soil. In seedbeds and small gardens 
they are particularly destructive as they feed on roots and 
destroy young plants while digging their runways. 
RECOMMENDATIONS (For Seedbeds) 
Spray or sprinkle seedbeds with a solution consisting of % 
gallon of an emulsion containing 25% DDT and 100 gallons of 
water. Apply to seedbeds several days before planting at the 
rate of one gallon to every 10 square feet. Beds should be 
sprayed both lengthwise and crosswise to insure even distribu- 
tion. 
RECOMMENDATIONS (For Fields) 
Broadcast Poison Bait No. 3-S (Contains sodium-fluosilicate) . 
Caution should be observed to prevent the bait in coming in 
contact with plants.
