meiits coincide with the second and third applications that are 

 reguhirly made for seal) and codling moth, and rather than make 

 a special application, frn it-growers are advised to add the nicotine 

 withont the soap to the lime-sulphnr and arsenate of load. The 

 presence of this insect in the orchard maj be determined bj plac- 

 ing domant twigs of hearing wood in water in a wainn room after 

 March first, and if eggs of these insects are present, small active 

 red bugs will appear which will attack the tender leaves. 



THE APPLE MAGGOT^ 



In addition to being called the apple maggot, the insect is also 



commonly known as the railroad worm because of the long, wind- 

 ing browmish channels made bv the 



Jan-ae or maggots in the fruit. 



The adult insects are flies. They 



appear in June and deposit eggs 



just under the skin of the fruit. 



These esgs hatch into maggots that 



burrow irregular channels through 



the fruit. Moderately infested fruit 



becomes rough and uneven due to 



the " stings " or egg punctures of 



(the fly. Badly infested fruit falls 



early and the maggots enter the soil, 



where they remain until the fol- 

 lowing spring. While many va- 

 rieties of ajjples are subject to 

 attack, the injuries are more pro- 

 nounced to certain sorts that ma- 

 ture in the summer and fall. 



Treatment. — It has long been 

 noticed that commercial orchards 

 that arc cultivated and thor- 

 (uighly sprayed are as a rule free 

 from injury by this maggot. 

 Xeglectcd orchards, particularly 

 summer and fall varieties of 

 apples, are susceptible to losses
