frequently the cause of serious trouble to tomato
growers, especially in the southern states, due to its pernicious habit
of eating into and destroying the green and ripening fruit. For its
control it is advisable not to plant tomatoes in proximity to old corn
or cotton fields, nor should land be used in regions where this species
is abundant until it has been fall or winter plowed. Sweet corn planted
about the field before the tomatoes are set will serve as a lure for the
parent moths to deposit their eggs, corn and cotton being favorite foods
of this species and preferred to tomatoes. The fruit worm feeds to a
certain extent on the foliage before penetrating the fruit, and it is
possible to keep it in subjection by spraying with arsenicals as advised
for the flea-beetles. It is suggested that arsenate of lead, being more
adhesive than other arsenicals, should be used for the first sprayings,
beginning when the fruit commences to form, repeating once or twice as
found necessary, and making a last spraying with Paris green within a
few days of ripening. This last poison will readily wash off and there
is no danger whatever of poisoning to human beings, as has been
conclusively proved in numerous similar cases. For the perfect success
of this remedy the last spraying is essential, as those who have
sprayed with an arsenical and have reported only partial good results
have discontinued within about two weeks of the time of the ripening of
the first fruit.

=White fly or aleyrodes.=--These minute insects are familiar to most
growers who raise tomatoes under glass. They can be held in control by
vaporization or fumigation with tobacco or nicotine extracts, or by
spraying with kerosene emulsion or the so-called whale-oil (fish-oil)
soap. Care is necessary in using the extracts that the smudge does not
become too dense and injure the plants. Before applying this remedy on a
large scale a preliminary trial should be made following the directions
on the packages, and reducing the amount if any ill results follow.
Hydrocyanic acid gas, properly used, is also an excellent remedy for
aleyrodes, aphides, "mealy-bug," and other soft-bodied insects which are
sometimes troublesome on greenhouse tomatoes.

hydrocyanic acid gas, see Professor Johnson's book entitled
