1 Premises for A. pattens are not shown, as this species is usually taken wherever traps are set. 
Larval infestations were found in four districts on five premises during the 
year. This represents a decrease of 25 premises from the previous year. 
Usually larval infestations, if any, occur during the early spring months. 
This past season, however, all of them were found in November and December. 
After the fruit had been removed from these premises and the trees sprayed, no 
other larvae were found throughout the remainder of the shipping season. 
The details as regards larval findings are shown in table 2.

OTHER SPECIES OF ANASTREPHA TRAPPED 
As in preceding years, several species of Anastrepha other than Uidens 
were taken wherever traps were operated. Continued inspections of wild and 
cultivated fruits have failed to establish a host for any of these flies except 
A. pollens. Apparently pallens is confined to one brush fruit of do economic 
importance. If any of these other flies have local hosts, they also are of no 
economic importance. 
FIELD INSPECTIONS 
The main phases of field work are grove inspection for infested fruit and 
unsanitary conditions, packing-house inspection, trapping, removal of alternate- 
host fruit trees and fruit, and tree-to-tree inspection at the beginning of the 
host-free period. 
Since many thousands of trees have conic into bearing within the yea-, it 
became necessary to add P» seasonal men to the personnel <>f this force from 
January through April. With these additional inspectors it was possibl • to 
intensify inspections and to operate more traps. 
The total grove and trap inspections are shown in table :'.. Traps Operated 
monthly averaged 8,149. A total of 41,388 alternate-hosl fruit trees have been 
removed since the beginning of the project.
