will so quickly suck the sap of the leaf and bud that it dies and
falls off.
To get rid of them requires patience. We must either hand-pick the
roses--or if we spray with the tobacco wash it is necessary to syringe
the plant with plain water first, using some force, to wash off the
white froth--and then spray with the tobacco wash to kill the "nymph."
This leads us to the more active and the worst of all the pests we have
to fight against.
BEETLES, BEES, FLIES, AND MOTHS,
which either in their adult form or as maggots and caterpillars prey
upon the rose.
Four Beetles are among the enemies of the rose. The beautiful green
=Rose Beetle= or =Rose Chafer= does harm in both stages. As a grub it
feeds underground on the roots; and as a beetle eats the foliage and the
petals and anthers of the flowers. I find it is particularly fond of the
delicate blossoms of the _Yellow Persian Briar_.
The =Cock Chafer= also eats the foliage, and its large white grubs
devour the roots of the roses to such an extent that they often kill the
plant. As the grubs remain for three years in the ground the damage they
can do is incalculable; and they attack other plants besides roses.
Among the roots of a herbaceous Spiraea I lifted this last winter, I
caught forty of these grubs, and found they had so honey-combed the
roots that the plant had to be burnt.
The =Summer Chafer= and =Garden Chafer= also attack roses.
Where these four chafers are prevalent there is no cure but
hand-picking. The beetles must be collected off the bushes; and the
grubs carefully picked out of the roots, if we have reason to think they
are present from the rose appearing unhealthy. Or they may be tempted
out of the soil by placing grass turves upside down close to the plants,
when they can be picked out and killed with a little boiling water.
The =Rose Leaf-cutting Bee= spoils the foliage by cutting semi-circular
pieces out of the leaves to line its nest. A few years ago I found that
a fine young plant of _Tea Rambler_ was so relished by this bee that
hardly a leaf was left intact. There is no cure but to watch the bee
going into her nest and there to destroy it after dusk.

Of all pests that the rose-grower has to fight against
CATERPILLARS AND MAGGOTS
are the very worst. For there is no real remedy against their endless
and varied depredations save hand-picking; or as some one has tersely
put it, "j
