THE ROSE APH1S.

rs soon as new growth starts on
roses in the spring and throughout
the summer and autumn the young
growth and flower buds are likely to
be covered with a small green and
pinkish plant louise. the rose aphls
The aph!des suck the sap from the
tender portion of the plant. causing
an unhealthful, curled condition Of the
foliage.
The aphis passes the winter in the
egg state on the stems and dormant
bius uf the bushes. According to \.
-. Hopkins. United States Forest En-
turnologist. the aphides Matched from
,hes" eggs reach maturity in about 90
or 30 days in n uingless state. .
this state they begin to produce living
young. each individual in the course
NJ about 20 days producing from 90 to
100 young insects which on maturity
are either winged or winsless and in
turn either green or rinkish. The ten
der growth OF roses soon becomes
crowded with various sizes, colors and
shapes Of aphides, and the wingless
mothers migrate TO less crowded
growths so as tn insure their progeny
an adequate supply OF food: the winged
ones fly to other bushes. each starting
"a colony for herself.
In favorable weather conditions,
especially In n humid atmosphere,
many generations follow n another
covering the green foliage Of the bush
with their bodies. their cast skins,
h~oneydew and the resulting sooty
fungus. Had every aph.s produced in
the course OF a season lived It's full
l.fc the progeny Of a single over
wintered egg would run into millions.
The presence Of ants on rose bushes
indicates that the aphis is present. The
ants collect the honeydew from the
aphides.
The aphides thrive best in cloudy.
humid, warm atmosphere. and with
the appearance Of hot and dry spells
they often disappear as suddenly as
they appear.
The rose aphil Is attacked by other
insects, which either devour them or
develop their fegs deposited ~ their

are sometimes called. lacewiug flies
and the laryn Of two winged flies
called surplus flies are among the
former and a number Of species of tiny.

parasites.
