WINE-MAKING IN CALIFORNIA. 43 



r~ 



But while the phylloxera is the greatest enemy to the grape- 

 vine, yet its ravages to a certain extent may be a "blessing in 

 disguise," especially for us here, where there is already the 

 cry of over-production. It may to a certain extent prevent 

 this, and has already decreased the production very seriously 

 in certain sections of the State. It will naturally destroy a 

 large amount of Mission, Malvasia, and others of the old, in- 

 different varieties, helping to take their wines out of the mar- 

 ket, and making room for a better product from choice vari- 

 eties, grafted on the young vines of American stock, and 

 make a better reputation and prices for our vines. It may 

 kill out the vines on many locations not suited to them, and 

 thus improve our coming product indirectly in many ways. 

 If we plant American vines on soils really adapted to them, 

 we need have no fears of the ultimate resultf] As the first 

 step, to successfully fight the enemy is to know where and 

 how to find him, I have quoted liberally from the report of 

 Prof. F. W. Morse, whose close study of the insect and its 

 habits at Berkeley and elsewhere have made him entirely fa- 

 miliar with it in California, and as it differs somewhat in its 

 habits here from those observed by European authorities, 

 they will be of greater value to us than theirs.

i. OBSERVATIONS ON THE LIFE HISTORY AND 



HABITS OF THE PHYLLOXERA IN 



CALIFORNIA. 



Made from 1881 to 1886 by F. W. Morse, Assistant in the General 

 Agricultural Laboratory. 



In the following pages I give a summary of the results of 

 observations made upon the phylloxera, since its discovery in 

 the University vineyard plot in November of 1881. Partial 

 reports of the same have already appeared in previous publi-
