38 EEPORT OF SEAECH FOR ENEMIES OF CITRUS WHITE FLY. 



at Port Said and Naples. Careful prearrangements enabled good 

 connections to be made at both of these ports, so that little delay 

 was experienced throughout the voyage. New York was reached on 

 November 28, exactly one month out from Bombay. 



The wiiter accompanied the sliipment and gave it his personal 

 attention thi-oughout the long voyage. The cases were kept on deck 

 except for the last three days out of New York when cold and stormy 

 weather necessitated their being placed below. 



CONDITION OF THE NATTJEAL ENEMIES ON ARRIVAL AT 

 ORLANDO, FLA. 



The cases were sliipped from New York to Florida by express, 

 arriving at Orlando on December 2, when they were immediately 

 taken to the Government laboratory. An examination of the con- 

 tents was at once instituted. The ultimate result was the recovery 

 of 28 active and healthy lady-beetles (Cryptognatlia fiavescens) and 8 

 adult Prospaltella JaTiorensis. A large number of living Prospaltella 

 in both the adult and pupal states were left in the cases. 



This condition of the shipment was all that could be desired. A 

 sufficient number of both the predatory enemy and the true internal 

 parasite had arrived in a Hving condition for breeding purposes. 

 Thus it seemed to the writer that his mission had been successfully 

 terminated. 



CONDITIONS AT ORLANDO, FLA., WHEN THE NATURAL ENEMIES 



ARRIVED. 



The writer's return in December was unfortunate but unavoidable. 

 White flies in Florida at this time are in a practically dormant pupal 

 state and continue in this condition during the winter months. 

 Although the winter weather in central Florida causes such tender 

 insects as the white fly to remain inactive, the more resistant species, 

 such as the Coccinellidse, are not completely driven into winter 

 quarters, but continue to be more or less active during many of the 

 warmest days. 



Mr. R. Wooldridge, an agent of this bureau then stationed at 

 Orlando, had on hand a large number of young orange trees infested 

 with the white fly for use in feeding the natural enemies. All these 

 insects, however, were in the pupal stage and then not suitable as food 

 for either of the two introductions, which attack only the younger 

 stages of the white fly. 



LOSS OF THE NATURAL ENEMIES. 



Without any experience to act u})on, it was not easy to determine 

 the best method of carrymg these parasitic and predaceous enemies 

 through the winter. In view of the writer's acquaintance with the
