nally, so as not to sever the vine from the root stalk. If the wound 
made by cutting be afterwards covered with moist soil it will assist it to 
heal. The location of the borer in the vine can be readily detected by 
the accumulation of its yellow ‘‘frass”’ or excrement at the point where 
it is working, and which is kept open for the extrusion of this matter. 
Capturing the moths —This species may be held in partial subjection 
by keeping a sharp lookout for the parent moths, which are readily 
seen and not difficult of capture toward dusk or in the cool of the 
morning, when they are comparatively inactive. The female may 
then be easily caught, just as she alights on a vine for oviposition.¢ 
Several persons, including the writer, can vouch for this statement. 
Summary.—lf the grower would make certain of securing a good 
erop in localities where this and other enemies of the squash occur in 
their most destructive abundance, it will be necessary for protection 
against this borer to observe most of the following precautions, and, 
if possible, secure the cooperation of his neighbors in their observance: 
(1) Not to plant in or near infested ground. 
(2) To plant early varieties for the protection of late squashes. 
(3) To harrow infested fields lightly in fall and plow deeply in spring, 
to prevent the moths from issuing. 
(4) To encourage the growth of secondary roots by covering the 
stems with earth. 
(5) To destroy dead vines and old plants as soon as the crop is 
made. 
(6) To keep the plants in vigorous condition, free from other insects 
and disease. 
(7) To cut out such borers as may succeed in entering the vines in 
spite of the employment of other remedial measures. 
The capture of the moths before egg deposition is also advisable.
