The old-fashioned remedy of hand-picking is of service when the 
beetles infest rosebushes or other low-growing plants. They may also 
be jarred from trees and bushes on to sheets saturated with kerosene, 
but these methods are tedious and must be practiced daily in early 
morning or toward sundown to be effective. A number of useful mechan- 
ical appliances formed on the plan of a funnel or inverted umbrella, with 
a bag or can containing kerosene at the bottom, have been devised for 
the collection of the beetles as they are jarred from the plants. 
Choice plants may be securely protected by a covering of netting, and 
when the process of bagging the grapes may profitably be employed, 
this method should be followed. Bagging, as is well known, is a pre- 
ventive of rot, and in addition, grapes so protected produce fruit of 
superior appearance and quality. 
Small orchards, gardens, or vineyards may be protected, at least from 
the first arriving hordes of the chafers, by planting about them early- 
flowering plants that particularly attract the beetles. Spirseas, Deutzias, 
Andromeda, magnolias, blackberries, and white roses are especially 
useful as counter-attractives. The beetles swarm on the flowers of these 
plants in preference to many varieties of grape and other fruits, and 
when thus massed in great numbers, their destruction by the use of 
collectors or other mechanical means is greatly facilitated. 
In addition to the use of any of the methods described above, injury 
to vineyards may be appreciably lessened by preventing the breeding of 
the insects upon or in the immediate vicinity of the vineyard. All 
ground which might serve as a breeding place and which it is possible 
so to treat, should be plowed and harrowed early in May for the destruc- 
tion of the larvee or pup. The least. possible amount of light sandy 
soil should be left in sod, only the heaviest land being used for grass. 
It is well also to stimulate the vines by the use of kainit and other 
fertilizers. 
Whatever of a remedial nature is undertaken, whether collecting or 
spraying, should be begun at the first onset of the beetles and continued 
until their disappearance. Nor should work be confined entirely to 
such useful plants as it is desired to preserve. Many weeds and wild 
plants, notably the ox-eye daisy and sumach, are special favorites of 
this species, and when practicable, the beetles should be destroyed on 
them, to prevent their spreading to cultivated land. 
If persistent and combined effort on the part of the fruit growers of 
a limited region were made against this insect, its numbers might, in 
a few seasons, be so diminished as to secure practical immunity from 
injury for several years.
