 THE PHILIPPINES 



In 1928 L. B. Uichanco published the statement that the Javanese 

 parasite {Encarsia flavoscutcUum) of the woolly aphis (Orcgma lani- 

 gcra), that had been introduced from Java into Formosa, was later 

 introduced from Java into the Philippines. 



Aside from this introduction from another country, most interesting 

 work has been done with presumably native parasites by Dr. W. 

 Dwight Pierce in the Island of Negros, but this is described rather 

 fully in our section on the Philippines in an earlier part of this book. 



PORTO RICO 



In 1 91 7 E. G. Smyth made a study of the possible enemies of the 

 white grubs injuring sugar cane on the island. He listed 15 North 

 American insects parasitic upon Lachnosterna, and urged their intro- 

 duction into Porto Rico. In the Journal of the Department of Agri- 

 culture of Porto Rico for January, 1922, G. N. Wolcott reports on 

 insect parasite introduction into Porto Rico. An attempt was made 

 to introduce Tiphia inornata from the United States. All attempts 

 failed. There was a similar failure with Elis collaris. Tiphia parallela 

 was introduced from Barbados, but did not breed. Cryptolacuins 

 montrotisieri was introduced, and easily became established ; but there 

 was a failure with an undetermined Tachinid from Illinois. 



Later, Mr. Harold E. Box, working for the Central Aguirre Sugar 

 Company, attempted for several years to find and introduce suitable 

 parasites of sugar cane insects. Mr. Wolcott's attempts at the estab- 

 lishment of such parasites from the mainland of North America 

 having failed, Mr. Box visited the Guianas and Venezuela and col- 

 lected a number of parasites that were introduced into Porto Rico. 



QUEENSLAND 



In 1921 or 1922 a predacious Histerid beetle {Placsius javaims) 

 was introduced from Java into Queensland to prey upon the banana 

 beetle borer. Three years later (Queensland Agricultural Journal, 

 December i, 1925) Mr. J. L. Froggatt, writing of this insect, stated 

 that there was at that time no evidence that it would become estab- 

 lished in Queensland. 



SOUTH AFRICA 



Professor Lounsbury of South Africa was impressed by the impor- 

 tance of the introduction of natural enemies of injurious species, and 

 in 1905 went to Brazil with Claude Fuller in an elifort to secure
