By Geo. P. Weldon, Chief Deputy State Commissioner of Horticulture. 



In the Anjjcnst number of The ^Monthly Bulletin, 1913, an account was 

 given of the above pe.st in hibernaculiX' as early as July 4th, at Ilanford, 

 Cal. This season on May lOtli larvae were found in freshly constructed 

 hibernating cells in crotches of yoimg peach trees, near Fillmore, Ven- 

 tura County. Again on June 23d in San Joaquin County near Stockton 

 an abundance of tiny larva3 Avere found in hibernacula\ In this case 

 they were in crotches of peach trees which were probably five years of 

 age and upon which there was considerable fruit. These observations 

 indicate the presence of only one strung-out brood of this insect instead 

 of three, or even four, as has been previously reported.

REPORT OF THE RESOLUTIONS COMMITTEE TO THE FORTY- 

 FOURTH STATE FRUIT GROWERS' CONVENTION AT 

 DAVIS, JUNE 1 TO 6. 1914. 



Through the Forty-fourth California Fruit Growers' Convention the 

 horticultural interests of the State have been presented with the most 

 comprehensive programme covering the different crops and the different 

 activities of the fruit growers that has ever been presented to the State. 



Distinguished investigators from other states, as well as from Cali- 

 fornia, have instructed our growers on the most modern and up-to-date 

 methods of horticulture, on handling of insect pests, fungous and other 

 diseases, and on the solution of the most important social and economic 

 problems confronting the fruit grower. 



This convention, therefore, desires to express its appreciation to the 

 State Commissioner of Horticulture, Dr. A. J. Cook, for the compre- 

 hensive programme presented to the Convention, for his efforts in secur- 

 ing the many distinguished men who have taken part in the discussion, 

 and for the general efficiency of his office, as shown in the handling of 

 this convention and in the various other matters with which he has to 

 deal.
