34. LIGHTS. 
The usual plan is to place a light over a dish of some sort that 
contains water with coal oil on top of it. Many night-flying insects 
are attracted by lights and may be destroyed by devises of this kind, 
but there are also many insects that fly at night that are not 
attracted by lights. Such an insect is the codling moth, though 
light traps are often recommended for its destruction. Among 
those insects that are readily attracted by lights might be mentioned 
the adults of the army worm, of the various cut-worms, the garden 
web-worms and the corn or boll-worm. 
It is not in frequent^ the case that more of the beneficial 
insects are destroyed than of destructive species, and it is quite 
doubtful if lights are often of any considerable importance as 
a means of lessening the injury to crops by the destruction of 
insects. 
35. SWEETENED WATER, CIDER, VINEGAR, ETC. 
Some insects are attracted in considerable numbers to such 
substances as the above, but it is very seldom that the benefit 
derived from them will pay for the trouble and expense of using 
them. Mr. David Brothers, of Edgewater, Colo., reported excellent 
success capturing moths of the fruit-tree leaf-roller with weakened 
vinegar in pans in the orchard, and the codling moth is attracted 
to some extent to a mixture of molasses and vinegar placed in apple 
trees. The advantage of such baits for the capture of insects 
is usually greatly overestimated by those who use them. 
36. BANDAGES. 
Heavy cloth or paper bands placed about the trunks of apple 
trees are quite useful for the capture of the larvae of the codling 
moth that are leaving the apples and going in search of a suitable 
place to spin their cocoons. Burlap bands are cheap and seem to 
be as good as any. The writer took 1,481 codling moth larvae 
under a single burlap band one season. Old gunny sacks cut into 
strips serve as well as anything. The band should be not less than 
four inches wide and should be composed of three thicknesses of the 
cloth. 
The bands should be wrapped loosely about the trunks, the 
ends overlapped and held in place by a single carpet tack pushed 
in with the thumb. * 
If used against the codling moth they should be removed once 
in a week or ten days for the purpose of killing all the worms and 
then replaced. 
The bands should be placed on the trees about the 10th of 
June in the warmer parts of the State, and about the 25th of June 
in the northern parts. 
Heavy paper may be used in place of the cloths.
