718 REpPoRT OF THE ENTOMOLOGIST OF THE 
would not be likely to injure the vines, if used not stronger than 
one part of the emulsion to from seven to nine parts of water. 
Prof. J. B. Smiths, * of the New Jersey Agricultural Experi- 
ment Station, recommends taking out and destroying the vines 
just as soon as the crop is off, or better yet, plowing the vines 
under in the fall, thus destroying every shelter for the bugs. Dr. 
J. A. Lintnert recommends placing bits of boards, chips, pieces of 
wood, etc., near the hills to serve as traps. The bugs will crawl 
under these during the day and may be easily captured and 
killed. He also suggests that leaves be stripped from the lower 
part of the vines and spread on the ground beneath. The bugs 
are particularly fond of the juices of wilted leaves and will 
accumulate under them in great numbers. These traps should be 
examined daily and the insects caught and destroyed. This 
may prove a great deal of work and would certainly be more 
practical on small fields than on large ones, but,it should be 
borne in mind that insect pests, and especially such pernicious 
ones as the squash-bug, can not be effectually checked without 
persistent and systematic effort. In those localities especially 
where the squash-bugs were numerous this past summer, their 
appearance should be watched for next spring and the first bugs 
caught and destroyed. . It will not pay to wait until the middle 
summer before beginning operations ; the young vines especially _ 
should be carefully examined for eggs which are easily recognized 
and should be destroyed. These preventive measures in the 
spring, together,;with the clearing away of rubbish and plowing 
in the fall, will do:much to check the work of this insect. 
From the above we may summarize thus as to remedies: 
1. When confined under a tight covering and exposed to 
bisulphide of carbon, squash-bugs are killed by it. Young bugs, 
those less than half-grown, are much more susceptible than mature ~ 
ones. 
¥. Pyrethrum powder is not practical as a remedy against the 
squash-bug. | 
3. Although kerosene emulsion will kill the old bugs if applied 
at a strength of one pint of the emulsion to four parts or 
water, it is not a practical remedy except in severe cases, as the
