BOX LEAF MIDGE 

 Monarthro palpus buxi Lab. 



The European leaf miner of the box has evidently become well 

 established in this country. It was first brought to our notice as an 

 American insect by the reception in May 19 10 of infested leaves 

 from Prof. A. E. Stene, who collected them at Newport, R. I. Sub- 

 sequent investigations have shown this insect to be thoroughly 

 established on Long Island. The box on one large estate at Roslyn 

 was generally infested and many of the plants were in a somewhat 

 weakened and very unsightly condition as a result of its attacks. 

 Reference to European literature shows this insect to be a common 

 and in some localities, a destructive pest. Professor Chaine even 

 attributing the death of box plants in the public garden of Bordeaux 

 to the work of this insect. 



Signs of infestation. The presence of this pest is indicated by 

 more or less irregular, oval swellings on the leaves (Plate 2, figure 1), 

 each marking an eccentric, oval, clear space mined beneath by one or 

 more pale yellowish- white maggots about one-sixteenth of an inch 

 long. There may be a very slight elevation on the leaf with an 

 irregular, yellowish or brownish discoloration, the margin of the 

 enlargement being indicated by darker green. This condition is 

 most easily noted in September and later aft cm- the maggots arc more 

 than half grown. An infested leaf may contain only one or two of 

 the miners and show comparatively little injury, or there may be six 

 or more of the pests with an accompanying destruction of the Larger 

 part of the Leaf. This attack, as intimated above, weakens the 

 plant and results in the badly infested Leaves dropping in the spring, 

 leaving unsightly, bare stems with new Leaves developing at the tip.
