Psila rosae Fabr. 



CARROT RUST FLY 



Ord. Diptcra: Fam. Psilidae 



Celery roots infested with a dipterous larva, which subsequently 

 proved to be this species, were received Dec. 30, 1901, from James 

 Granger, Broadalbin, who states that the attack was confined to 

 the roots and crown, never interfering with the stalk. Several 

 larvae were taken from one root, and their burrows, about ^ 

 inch in diameter, were lined with reddish particles of comminuted 

 tissue. The galleries were found in the roots near the crown and 

 also in the crown and frequently ran obliquely for a distance 

 partly around the root or crown, as the case may be, and in some 

 instances they were near the center of the infested plant. The 

 attack was a serious one, as is evidenced by the ruining of about 

 GOOD plants. Traces of the insect were found ail over a field 

 containing some 00,000 plants. 



Introduction and injuries in America. This is a European insect, 

 which prior to 1SS5 was not known to occur in this country. It 

 was then reared by Dr Fletcher from carrots purchased in the 

 market at Ottawa, where the following year he found young 

 carrot plants in a garden badly attacked. The same year 

 a great deal of damage was done, particularly to stored roots
