NOTE ON THE CORK-COLORED ORANGE TORTRICID ^ 



Platynota rostrana Walker 

 By E. R. Sasscer, Bu. Entom. Dept. Agric, Washington, D. C. 



The Cork-Colored Orange Tortricid was first described by Walker ^ 

 in 1863 from material collected in the United States and St. Domingo 

 and Ega Hubbard in "Insects Affecting the Orange" gives a brief 

 account of this insect in which he states that it is injurious to nursery 

 plants and occasionally damages the fruit by puncturing the rind. 

 Although the larvae of this insect frequently bore into the rind of 

 citrus fruits, no observations have as yet been made which would 

 indicate that they enter the fleshy part of the fruit. From time to 

 time letters have been received by the Bureau of Entomology, rela- 

 tive to the appearance of this pest in various sections of the country, 

 but in only a few instances have they been reported as doing serious 

 damage. 



In February, 1909, Mr. Edward Gottfried of Key Largo, Fla., sub- 

 mitted grape fruit infested with this insect and subsequently gave a 

 report on the conditions as they existed in his grove. According to 

 his estimate fully 15 per cent of the fruit was damaged by the larvae 

 of this tortricid. In March of the same year. Dr. L. A. Peck of Mel- 

 bourne, Fla., reported this insect present in his grove, stating that 

 he had observed the punctures made by this pest for a number of 

 years but had not hitherto seen the larvae. After several failures in 

 the attempt to rear the adult of this insect, the writer was finally suc-
