REPORT OF THE STATE ENTOMOLOGIST I913 7 



A number of other insect pests of fruits have been studied and 

 records concerning them are given in a series of classified notes. 



Gipsy moth. The small colony of the gipsy moth, discovered 

 last year, appears to have been completely exterminated. This 

 occurrence proves, in a concrete manner, the danger of the insect 

 becoming established in New York territory, and amply justifies 

 the maintenance of rigid precautions to prevent this. Evergreens 

 and shrubbery grown in sections where gipsy moth is known to 

 occur should be examined most carefully, especially in the case of 

 evergreens. The presence of broken egg masses usually means the 

 occurrence of living eggs in the packing material or about the roots 

 of the plants in the same bale or box, and a due regard for the 

 public welfare necessitates the destruction of the shipment or the 

 part of the shipment exposed to infestation of this character. 



Brown-tail moth. There is little to report concerning the brown- 

 tail moth, though the danger of its establishing itself in the State 

 has not decreased. It is only a question of time before this occurs. 

 The winter nests are so characteristic that there should be little 

 difficulty in recognizing the pest and at the outset preventing its 

 becoming extremely abundant. 



Grass and grain pests. The white grub outbreak of last year 

 has largely abated, partly at least as a result of various natural 

 causes. The studies of last year have been continued. The most 

 interesting development was the discovery of many large beneficial 

 maggots of P r o m a c h u s f i t c h i i O. S. They were abundant 

 in fields badly infested by white grubs the preceding year, and at 

 the time of observation last spring, nearly free from the pests. 



A rare or usually overlooked corn pest, the lined corn borer, 

 Hadena fractilinea, was destructive in Ulster county 

 fields. A full discussion of this relatively new insect is given in the 

 body of the report. 



The discovery of the European wolf or grain moth. Tinea 

 granella, in a local seed warehouse adds another to the list of 

 important grain insects. A careful study has been made of this 

 insect and a detailed discussion appears elsewhere. 



Shade tree insects. Observations show that the comparative 

 immunity from severe injury by the elm leaf beetle the past season 

 is probably due to the exceptionally cool weather in June, a time 

 when the laying of eggs by this pest is at its height and the period 

 when adverse climatic conditions might be expected to exert a 

 maximum influence. There have been some cases of very severe
