 In California the thrips attacks deciduous fruits, including al- 

 mond, apple, apricot, cherry, fig, grape, peach, pear, plum and 

 prune and the English walnut. In England it has been found in 

 wild plum blossoms. During the past year the thrips was observed 

 in New York chiefly on apples, apricots, cherries, peaches, pears, 

 plums and quinces. 



LITERATURE. 



The literature dealing with this species is not extensive as it 

 has only in recent years come to be seriously considered by both 

 systematic and economic workers. The insect was first described 

 in 1904 by Miss S. M. Daniel in Entomological News,^ from 

 Bpecimens obtained from pear blossoms in the vicinity of San 

 Leandro, California. In 1905 a circular entitled " The Pear 

 Thrips " by Dudley Moulton was issued by the California 

 State Commission of Horticulture which called the attention of 

 the fruitgrowers of that State to the destructiveness of this new 

 pest to the deciduous fruits. This author has continued his inves- 

 tigations on the life history and habits of the pear thrips and 

 methods of control which are discussed with considerable detail 

 in bulletins of the United States Department of Agriculture.^ 

 A circular by S. W. Foster and P. P. Jones^ of the same Bureau 

 is more popular in its nature and is a most serviceable publication 

 for the orchardist. It holds out encouragement to fruitgrowerb 

 for the control of the thrips by eifficient spraying.

EXPERIENCE OF FRUITGROWERS. 



The occurrence and discovery of the pest for the first time in a 

 region so remote from its heretofore known range of distribution 

 in the United States constitute in themselves interesting facts. 

 The questions now arise how long has the thrips been established 

 in the Hudson River Valley and what is its importance to the
