The apple maggot or railroad worm i^ a somewhat se- 

 rious pest in many orchards. The control of this insect de- 

 pends in large measure on good orchard practices, such as 

 cultivation, the usual spraying and the destruction of wind- 

 falls. There have been very promising results obtained in 

 some orchards infested by this pest by spraying with an ar- 

 senical poison at about the time the flies appear on the trees, 

 which in the case of winter apples, is apt to be from early 

 until toward the middle of July. Those having serious diffi- 

 culty with this pest may well try this method, especially if 

 the orchard be somewhat isolated or there be an opportunity 

 to secure by co-operation similar treatment in nearby or- 

 chards. 



A discussion of this character would hardly be complete 

 without mention of two recently introduced insects known 

 as the oriental peach moth and the apple and thorn skeleton- 

 izer, both of which have established themselves in New York 

 State and have not, like the gypsy and brown tailed moths, 

 entered the country through New England. 



The oriental peach moth is probably generally distrib- 

 uted over most of Long Island and specimens have been re- 

 ceived from Stamford, Conn. It also occurs at Rutherford, 

 N. J., and in the vicinity of Baltimore and Washington. Its 

 presence is indicated by wilting leaves and bored terminals 

 in late summer. It is specially destructive to peach and at- 

 tacks apple and pear and probably breeds equally well in cul- 

 vated pome and stone fruits. Badly infested trees may have 

 practically every twig attacked and as a consequence there 

 is a much branched, bushy growth. This pest also attacks 

 peaches, generally entering near the stem and penetrating 

 to the pit. The habits of this new pest are such that no prac- 

 tical control methods can be suggested at the present time. 



The apple and thorn skeletonizer has become well estab- 

 lished in portions of "Westchester County, N. Y. It is an Eu- 

 ropean insect classed as of minor importance and the proba- 

 bilities are that it will not be specially dangerous, thornrh in
