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) 
The U. S. Department of Agriculture (U. S. Dept. Agr. Bureau 
Entomology and Plant Quarantine, E-497, Feb. 1940) recom- 
mends the use of a solution of pyrethrins 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 knap- 
sack 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.

HORNWORMS. These large worms are the larvae of several 
of the hawk moths. Often they reach a length of three to four 
inches. They bear a slender “horn” on the rear end. 
SPRAY RECOMMENDATIONS FOR THE CONTROL OF 

MEXICAN BEAN BEETLE. The beetles are yellow to cop- 
pery brown with eight small black spots on each wing cover. 
The larvae are yellow, bearing six rows of long branching black- 
tipped spines. Both the adults and larvae are destructive to 
bean foliage as well as pods.

Adult 
LADY BEETLE. The adults of some species are red with 
black spots, some black with red spots, others reddish yellow, 
and a few are entirely black. All of them have short, club-like 
antennae (feelers). The larvae are dark-colored, often showing 
a few spots of yellow or blue on the side of the body. Their 
shape reminds one of a tiny alligator. With the exception of 
the Mexican Bean Beetle, the entire family is entirely bene- 
ficial to man, as its members (both adults and larvae) feed on 
small insects, particularly aphids. No attempt should be made 
to destroy either the beetles or the larvae. 


SQUASH VINE BORER. The 
moth is wasp-like of appearance. 
It is colored beautifully by having 
bs the front wings covered with me- 
tallic-shining green and olive-brown scales. The hind wings 
are transparent. The abdomen is ringed with red, black and 
copper. The body of the larva is white, the head being brown. 
Immediately upon hatching, the young larvae bore into the 
vines of squash and other cucurbits, although certain varieties
