If the wound made by cutting be afterward covered with moist soil 

 it will assist it to heal. The location of the borer in the vine can readily 

 be 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. 



Captui'ing the moths. — This species may be held in partial sub- 

 jection 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 

 be easily caught, just as she alights on a vine for oviposition.* 



Summary . — If the grower would make certain of securing a good 

 crop in localities where this and other enemies of the squash occur 

 in their most destructive abundance, it will be necessary for protec- 

 tion 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 deeplj" 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 employ metit of other remedial measures. 



The capture of the moths before e^^ deposition is also advisable.
