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 1900 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 José 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 Endant 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
