6S SECOND REPORT OF THE STATE ENTOMOLOGIST. 



burrows. Next to this comes the coal-tar employed as a counterodorant, 

 showing in the same number of hills but three burrows ; and, third, the 

 Paris green water with eight burrows. 



The average protection shown in the above experiments (not including 

 that with the copperas water) is eighty-one per cent — a highly gratifying 

 result. 



Had the applications been commenced about the first of July, instead 

 of the middle of the month, it is probable that the results would have 

 been still more satisfactory. The moth, in the State of New York, may 

 commence the deposit of its eggs during the first week of July. The 

 coal-tar would act by preventing the deposit, while the Paris green water 

 and the soap emulsion operate by killing the young larva upon its hatch- 

 ing from the egg and beginning to eat into the vine. 



In a subsequent communication, Mr. Goff, in reply to inquiries, con- 

 tributes these items relating to the life-history of the species : 



" Strange to say, I found but two live larvae ; in almost every case they 

 had left the vines for transformation. ****** j found no 

 pupse within the vines. In one or two cases the caterpillar seemed to 

 have died ; at least, I found in the cavity a mass of white matter. 

 ****** J noticed that the borers are often found in the stem 

 at a greater distance from the base than I had supposed — often four and 

 even six feet from the base. Strange to say, however, in the ' Perfect 

 Gem ' squash I found the borer only close to the base, in no case, I be- 

 lieve, in a branch, but always in the main stems. ****** 

 The ' Perfect Gem ' seems less liable to attack from the borer than the 

 ' Hubbard.' I had noticed this fact in previous seasons."
