zations and proportionateh' smaller expenditures and the work of com- 

 bating whiteflies in some cases could be conducted to best advantage 

 by means of one organization supported jointly by two or more 

 adjoining counties. 



Organization of Officials for Efificient Service 



In Florida the office of State Horticultural Commissioner would be 

 practically superfluous as regards whitefly control. Rather than create 

 such an office, the writer would strongly recommend that offices 

 already existent in connection with the State Experiment Station be 

 given additional support. It would be especially undesirable and a 

 serious impediment to progress in whitefly control for an organiza- 

 tion to be provided for, which would place a State Horticultural Com- 

 missioner or other official in charge of all the work of the state. For 

 effective results the officials in charge must have an opportunity to 

 come in close contact with actual field conditions having supervision 

 over the work in limited territories — only a single county in many 

 instances. They must be competent as to entomological matters, 

 of good executive ability, and must J^e able to command the respect and 

 confidence of the citrus growers. Such men must be as able men in 

 their fine as it is possible to procure and should not be subject to the 

 direction of an official superior. 



An assistant to the official in charge, capable of acting in charge of 

 all work temporarily as the occasion may demand, one or two inspec- 

 tors and an office assistant are needed to complete the organization 

 in a leading citrus growing county. The attempt to accomplish 

 satisfactory results in combating the whiteflies in Florida in such 

 counties as Orange, Lake, Polk, Lee, De Soto, Manatee and Hillsboro 

 wath a smaller organization than that mentioned would be a serious 

 mistake, at least until such time as a satisfactory condition of control 

 is brought about and experience shows the practicability of reducing 

 expenses in this manner. 



The organization of the various county entomologists into a State 

 Crop Pest Commission as hereafter outlined is advisable in order to 

 give each local official status as a state officer for legal reasons, in 

 order to establish state quarantines when necessary and also to secure 

 as far as practicable uniformity of methods in administering the State 

 Horticultural Law in the different counties. 



State Laws 



The states of Louisiana and Texas already have horticultural laws 

 which, with proper financial support, might be administered to good 

 effect in the control of whiteflies. Dealing with trees which average
