New York Agricultural Experiment Station. 439 



dering New York on the east, south and west. At present there 

 is no law to hinder the importation of infested stock from all of 

 these directions and no provision made for a systematic effort 

 to prevent the further spread of this and' similar pests within the 

 State. 



The 'insects discussed in this bulletin have been found in more 

 or less abundance in the nurseries from time to time. All of 

 them are readily transported on nursery stock and hence are of 

 importance to the nurseryman as well as the fruit grower. 



The problem of how best to control the numerous species of 

 insects which attack the growing plants in the nursery is a very 

 important one. The few experiments noted in this bulletin are 

 incomplete, but it is expected that as opportunity is afforded they 

 will be continued until more definite results are reached. This 

 work will be greatly aided by the increased facilities at the 

 Station. 



INSPECTION OF NURSERIES IN WESTERN NEW YORK. 



Method of Inspection. 

 The immediate surroundings of the nursery were first noted 

 and any old neglected orchards bordering on the nursery, or neg- 

 lected blocks of stock were first carefully examined. On several 

 occasions neglected apple orchards or a few old neglected apple 

 trees were found badly infested with various species of injurious 

 insects, principally the woolly aphis. Further examinations 

 showed that many of the nursery trees in the immediate vicinity 

 were infested with the same species, the indications being that 

 the insects had originally come from the old trees. After the 

 orchard trees were examined the condition of the more immediate 

 surroundings of the blocks, such as the fence corners, etc., were 

 noted and any suspicious looking shrubbery subjected to a care- 

 ful scrutiny. The nursery rows were next examined, the usual 

 method being to go back and forth across the rows a number of 

 times until the general appearance of the trees was well noted. 

 All suspicious looking trees were, of course, carefully examined. 

 Where possible, the examination was repeated two or three times 

 during the season.
