22d REPORT OF THE STATE ENTOMOLOGIST 1906 



To John M. Clarke^ Director of Science Division 



I have the honor of presenting herewith my report on the injuri- 

 ous and other insects of the State of New York for the year ending 

 October 15, 1906. 



The season of 1906 has been marked by relatively few extensive 

 depredations by insect pests. This is particularly true of the forms 

 affecting garden, vegetable and other common farm crops. A 

 remarkable large South American moth (Thysania zenobia 

 Cramer) was taken in Albany the last of September. This mag- 

 nificent moth has a wing spread of about 5 inches and its occurrence 

 in this city is undoubtedly due to its having been brought north with 

 a boat load of bananas or other tropical fruit. This capture is an 

 example of the way in which insects are distributed through com- 

 mercial agencies, though in the present instance it happens to be 

 a species which can not sustain itself in this latitude. 



Fruit tree insects. The San Jose scale is still regarded as a 

 serious pest of the horticulturist, though the experience of recent 

 years has demonstrated beyond question the practicability of keep- 

 ing this insect in check by thorough and timely applications of a 

 lime-sulfur wash. Our experiments conducted during a series of 

 years show this insecticide to be fully as satisfactory as any other 

 material which has been employed, despite the fact that a number of 

 new preparations have been put on the market in recent years. 

 These latter, though they possess certain very desirable qualities, 

 have not been tested sufficiently so that they can be recommended 

 without qualification. 



We find the grape root worm still abundant in the Chautauqua 

 region and the present indications are that some vineyards may be 

 seriously injured by its depredations within a year or two. This
