34 BULLETIN 3 3, PORTO RICO EXPERIMENT STATION 



Mention is made of the destructive insects and diseases commonly 

 encountered in citrus groves and after the fruit has been picked, 

 and a brief description is given of the control measures commonly 

 employed for them. 



Harvesting and handling of citrus fruits is fairly well standard- 

 ized, but some of the packing-house operations need further per- 

 fecting. Coloring of fruit artificially in the early season and the 

 various factors affecting coloring have been studied and are discussed.
