other cucurbit enemies would be prevented by more attention to clean 
methods of cultivation. As soon as a crop is harvested the vines should 
be covered with straw or other inflammable material and burned, and it 
would be a wise precaution to have certain plants (e. g., such as might 
be desired for seed) left standing here and there throughout the fields, 
so that such insects as may not have been reached by the fire will con- 
centrate on them where they can be easily destroyed with a spray of 
strong kerosene emulsion or Paris green. As traps for the last or hiber- 
nating generation, it would be wise to plant later or to use later 
varieties. By destroying the beetles at this time the numbers for the 
ensuing year will be greatly diminished. 
Some exemption from injury, it is claimed, may be attained by grow- 
ing beans in connection with cucumbers, for example, in alternate rows. 
The beans are planted before the cucumbers, and the beetles congregate 
on these plants, and having an abundance of food are not forced by 
hunger to attack the young cucurbits. 
Gourds planted in the vicinity of other cucurbits are claimed to act 
successfully as a trap, and wild cucumber might produce good results. 
Driving with air-slaked lime.—In the melon and squash-growing 
sections of New Jersey © driving”’ is resorted to as a means of con- 
trolling this insect. In the morning when the beetles are active, air- 
slaked lime is dusted over the plants with the wind and the beetles fly 
before it to the next patch where similar methods will have to be 
employed or the crop will suffer the consequences. 
Arsenites, with ashes, dust, or plaster.—A remedy frequently advised, 
when insects occur on low-growing plants, is to dust the majority of 
them with sifted wood ashes, road dust, or land plaster, and cover the 
remaining plants with a solution of Paris green or other arsenical in the 
proportion of one-fourth of a pound to about 60 gallons of water. The 
beetles will concentrate on the clean plants, where they will be killed 
by the poison, not always, however, before they have fed to such an 
extent that the plants will be more or less damaged. 
Dry arsenicals.—Paris green and other arsenicals alone or mixed 
with plaster, in the proportion of 1 to 75 by weight, and dusted over the 
plants will effectually protect them in many cases. . 
Pyrethrum, dusted on the plants with a powder bellows, is useful, 
and the only treatment that is necessary under ordinary circumstances. 
This treatment is most successful if applied early in the morning when 
the dew is on. All poisonous and other applications must be frequently 
renewed and are not generally to be relied upon when the beetles are 
exceedingly numerous. In case Bordeaux mixture is sprayed on the 
plants as a protection against diseases, Paris green should be added, 
as it necessitates no additional labor and the mixture will prove more 
effective against the beetles than would either when used alone.
