ENTOMOLOGICAL TEACHINGS 

 TEAR TIIKIPS 



During the past year this pest has been found to exist throughout 

 the Hudson River Valley, ranging from Mousey near the New 

 Jersey State line to Albany, N, Y. It has been especially destruc- 

 tive in the region extending from Hudson to Germantown. This 

 specie also exists in western New York, although it has not so 

 far been destructive to fruit trees. This insect is thoroughly dis- 

 cussed in Geneva Bulletin 343. 



GIPSY MOTH 



The discovery of this pest in one locality in New York would 

 indicate the possibility of its being present in other parts of the 

 state. Institute lecturers are advised to secure illustrated chart 

 from the Department of Agriculture, Albany, N. Y., and to call 

 attention to the characteristic appearance of the caterpillars so 

 they may be recognized from other common, native caterpillars. 



PEAR PSYLLA 



Great progress has been made in the control of this pest. There 

 is no reason why it cannot be efficiently handled. Workers should 

 secure Leaflet " O " of the Geneva Station. 



GRAPE THRIPS 



This pest has been especially destructive in Chautauqua County, 

 in the Keuka-Lake region and in the Hudson River Valley. It 

 has been successfully combated by using one gallon of " black 

 leaf 40 " to 1,600 gallons of water. Only one application need be 

 made. Time to apply the spray is during July when the insects 

 appear in numbers. Tobacco may be used with bordeaux mixture 

 and arsenate of lead. 



EARLY LEAF EATING AND FRUIT EATING INSECTS 



There are a number of species, such as bud moth, case bearers, 

 green fruit worm and canker worms which make their appearance 

 during certain seasons and cause quite a little damage in some 

 orchards. More emphasis should be placed by institute workers on
