316 Vineyard Culture. 



The larvae are rather tenacious of life. When not numerous, 

 the most certain method of shortening their days, is to pick 

 off the infested leaves, and to burn them ; but this can not be 

 done when they are very numerous. I would recommend 

 syringing with lime, or very strong soap-suds — ^whale-oil soap 

 is the best. Dusting newly air-slaked lime on the leaves, when 

 dry, will probably have a good effect." 



In the lake-shore vine-region, of Ohio, a curculio — species 

 unknown — has been found, affecting the shoots of the current 

 year's growth. The egg is deposited at some time during the 

 summer. A mark similar to that found upon the plum is seen 

 on the bark of an internode ; on cutting open the wood, a 

 small worm is found, unless it has changed to the beetle, when 

 it escapes through a small, round hole. My attention was 

 directed to this insect by Charles Carpenter, of Kelley's Isl- 

 and, who may be called the pioneer grape-grower of that 

 favored region. 



The grub being yet a study for entomologists, and com- 

 paratively little known, I have not been able to identify this 

 species. It will probably be spread, by transporting cuttings 

 and vines. 



The common curculio, Conotrachelus nenuphar (Herbert), 

 is accused of depositing its eggs in the grape, as in other 

 smooth-skinned fruits. This is doubted by many observers ; 

 and, forsooth, the little Turk has sins enough to answer for 

 without having this laid to his charge. 



In the next order — the Orthoptera — we find the tree crickets, 

 some of which deposit their eggs in the vine shoots that 

 are marked with a roughish raised line between the joints ; if 

 cut or broken, the fibers will be found pierced and torn to the 

 pith, and a double row of yellowish eggs may be seen. These 

 insects were formerly supposed to be vegetable feeders, but 

 from an article in the Practical Entomologist for February, 1 867, 

 it appears that one species, at least, may prove to be a valu-
