thereof is unnecessary. Formulas 9 and 10, making 20 and 25% 

 kerosene limoid washes, were tested under several conditions and 

 generally speaking the results were not equal to those obtained 

 with lime-sulfur washes, though there is no doubt but that a certain 

 amount of scale was destroyed by the application. The general 

 results were disappointing even in the hands of other persons 

 where the treatment was said to be exceptionally thorough. 



NOTES FOR THE YEAR 



The following brief accounts relate to some of the more inter- 

 esting species observed during the season, and are grouped as 

 heretofore under appropriate heads. 



Fruit tree insects 



Codling moth (Carpocapsa pomonella Linn.) , This 

 species is well known as the apple worm and is more or less 

 abundant from year to year. The season of 1905 has been marked 

 by considerable injury in different sections of the State, which 

 was further emphasized by the scarcity and high price of apples. 

 The second brood of this pest appears to have caused the greater 

 part of the damage, particularly in the Hudson valley. Some 

 growers, thinking the pest was rather scarce, did not spray at all 

 and as a consequence suffered greatly where others, making the 

 usual applications but not expecting a second brood, were injured 

 to a considerable extent. This is only another instance emphasiz- 

 ing the necessity of constant watchfulness if one would escape 

 severe losses through insect depredations. 



Apple maggot (R h a g o 1 e t is pomonella Walsh) . This 

 species is a very common and destructive pest of early apples, 

 particularly sweet varieties in New England. It is only occasion- 

 ally brought to notice in this State. Mr C. H. Stuart of Newark, 

 writing August 8, states that this insect was very numerous in 

 early fruit, it being so abundant that he was unable to find a sound 

 early apple. Mr W. H. Hart of Poughkeepsie, a large fruit grower, 

 also called our attention to the work of this species, stating that 

 in his experience it was much more abundant and injurious in 

 sheltered hollows than on side hills or other places where there is 

 presumably more air. This species is a somewhat local form and 

 it is very probable that it is affected to a considerable extent bv 

 wind currents, since it appears to exhibit a marked tendency to 

 assemble in sheltered places.
