The Insect's Future as a Pest. The insect has been a serious pest on 

 Mr. Smith's farm, and it is the belief of the writer that prompt meas- 

 ures should be taken against it as soon as its work is observed. As 

 stated previously, the female is very sluggish in her movements, 

 apparently being scarcely, if at all, able to fly. This, taken in con- 

 sideration with the fact that gooseberries are rarely grow^i on a very 

 extensive scale and usually are found in isolated patches, indicates 

 that there is little likelihood of the pest becoming generally distributed. 



Natural Enemies. No parasites have been observed working upon 

 the insect, but several dead larvae have been observed, apparently 

 killed by some bacterial disease. 



Remedies. The remedy is so obvious, now that we know some- 

 thing of the life history, that it seems scarcely necessary to state it, 

 namely: cutting out and burning the gall clusters during the fall or 

 winter. The work in order to be effective must be done with care 

 and thoroughness, for quite frequently isolated galls occur which are 

 difficult to find, and these by escaping destruction would be sufficient 

 to perpetuate the species. 



President F. L. Washburn : Any discussion upon this paper? 

 If not we will pass to the next paper on the programme, "Occur- 

 rence of Pear Thrips in New York," by Mr. Parrott. 



THE OCCURRENCE OF THE PEAR THRIPS IN NEW YORK 



By P. J. Parrott 



This species, Euthrips pyri Daniel, has attracted much attention in 

 recent years because of the course which it has run in California. Its 

 importance to the deciduous fruits of that state, and the efforts^ that 

 have been made to establish more efficient methods of control are well 

 known. Peculiar interest is now centered in the thrips because of its 

 presence in a region very remote from its heretofore recognized area 

 of distribution, where it is playing a like role as a destructive fruit 

 pest. It is the purpose of this paper to present some observations 

 upon its distribution and work in orchards in New York. 



Distribution in the State. The pear thrips was discovered first 

 at Germantown in the Hudson River valley where it was very destruc- 

 tive in many orchards in the immediate vicinity. The pest was
