other insects. The enemies OF this
apals include the following.
L rhe lady hug and their Young
The latter are dark c0lored worms
With few reddish spots on their
backs. and six legs on the under side
near the head Many of these are
now transforming 70 the adult stage,
On doing this they attach themselves
BY the tail 10 an object, shed their
SKINS, turn from dark 20 a light yellow
,0ler and soon transform to the
aeefle stage Both the young and the
ldait lady bugs consume about fifty
lphlas apiece per day
, The lace wing flies and their
oang The adults are about one inch
ong. OF q greenish color. and have
four laee-hke wings They lay their
title pearl c0lored eggs on pale
lender stalks about an inch long
These hatch into six-i0oted larvae or
worms. which are somewhat similar
a form and habit to the larvae of the
adY hug
3. The scymnus beetles and their
Young The former Is q little round
lark brown. or black beetle about
onefourth the size OF the lady bug,
rhe Young Is covered with Il white
xooly coat Their food habits are
similar to those Of the lady hug. hut
m account az their size they can
levour only about one-third as MANY
lphids as the former.
e. Several species OF young
syrphus flies. The adults are yellow,
sh in color and are sometimes
,nown as sweat bees They eat the
Nouey dew secreted by the aphids
hut their young. which are footless
'lug-like worms. eat about as many
gphids rs the lady bugs
5. The internal parasites These
IN many places are now present in
numbers equal to the melon aphis
They are like the little bees that sting
md lay eggs in the green bug. A
few days after an egg is laid in the
body of she melon louise hy them, the
l0use turns brown and IS attached to
the leaf by the young bee which
matches from the egg Within a weeh
or ten days the young bee gnaws a
circular hole i'm the top Of the aphid's
body. through which II escapes.
