66 SECOND REPORT OF THE STATE ENTOMOLOGIST. 



grapevines, as narrated in the Country Gentleman of March 6,1884, 

 page 191. In that instance small vials containing a few drops each of 

 the liquid were tied among the vines at intervals of a foot or two, the 

 liquid being renewed every three or four days. As the result, grapes 

 were grown upon the trellis as far as the vials were hung, while beyond, 

 all the blossoms were eaten by the beetles. The cost of the bisulphide 

 of carbon distributed in the twenty vials employed was less than twenty- 

 five cents. The best method of using this material as a protection of 

 squash vines, may safely be left to the judgment of the squash-grower. 

 Coal-tar, naphthaline, etc. — Coal-tar, as a preventive, might be dropped 

 in patches upon the ground near the root and vines. Tar-water might 

 be sprinkled over the ground. Pieces of cloth might be saturated with 

 kerosene oil and wound upon sticks thrust in the ground, or sand moist- 

 ened with it scattered upon the surface. Lumps of naphthaline would 

 yield their strong odor for some time if lightly covered with the soil. 

 Carbolic washes, if not too strong, could be sprinkled over the plants. 

 Different methods of use of the above, as well as other materials, will 

 undoubtedly come to the mind of one familiar with the cultivation of 

 the squash. 



Additional Information of the Insect Asked For. 



That the remedies and preventives to be employed against this insect 

 may be the best directed and the most effective, I would solicit the aid 

 of all interested in the cultivation of the squash whom these lines may 

 reach, in sending me information upon the following points. Each one 

 should regard it as his duty to contribute, from his observations, to 

 the extent of his ability. 



Earliest date of the appearance of the moth. Latest that the moth is 

 seen. 



Is the egg ever deposited upon the root-stalk .-* If so, how often ? 



Greatest distance apart upon the vines that the egg is placed or the 

 borer found. 



Are the eggs placed on the upper or lower sides of the vines, or in- 

 termediately ? 



Is the borer ever found in the main stalk ? 



Earliest and latest notice of injury from the borer. 



Earliest maturity of the borer and escape from the vine for pupation. 



Are the cocoons ever found within the vines 7 



At what depth in the ground are the cocoons buried ? 



Are the cocoons ever found far from the vines ? 



Does the caterpillar ever change within the cocoon to the pupa during 

 the autumn or winter? (In this stage it shows the legs, wing-covers and 

 other organs of tlie future moth.)
