THE APPLE MAGGOT, OR RAILROAD WORM 3 1 



worm nibblesat the skin, it is likely to eat one of these particles 

 and be killed. To accomplish this purpose the orchardist mixes 

 four or five ounces of Paris green in a barrel holding forty or 

 fifty gallons of water, and then having the barrel in a wagon, he 

 drives along the rows of trees, just after the blossoms have fallen 

 off, and sprays them by means of a force pump and spray nozzle. 

 The little particles of poison are thus distributed over the tree 

 in a fine mist, and when the water in which they are suspended 

 evaporates, they are left high and dry upon the leaves and fruit, 

 where under favorable conditions they remain for several weeks 

 a menace to insect enemies, until the combined action of rain 

 and dew, wind and sunshine, dissipates their poisonous pro- 

 perties. The first brood of worms being thus destroyed, the 

 development of the second brood is checked. 



The spraying is done when the apples are from the size of a 

 pea to the size of a hickory nut. Two, and in case of very wet 

 weather three, applications are advisable. Paris green is almost 

 insoluble in water, but there is often a small percentage of it 

 soluble, and to prevent the injury this may do to foliage it is 

 advisable to add a quart or two of fresh lime water, made by 

 slaking fresh lime in water, to each barrel of the spraying mix- 

 ture. Or the Paris green may be used in combination with 

 the Bordeaux mixture. 



The philosophy of spraying for the Codling Moth rests upon 

 the fact that the egg is laid upon the outside of the fruit, and 

 consequently the young worm has to nibble through the skin, 



THE APPLE MAGGOT OR RAILROAD WORM 



Trypeta fomoneUa 



This is the most troublesome apple pest in the state, and as 

 already intimated it is increasing in destructiveness from year to 

 year. The injury of this insect is at once distinguished from 

 that of the Codling Moth by the fact that while the latter is 

 largely confined to the region of the core, the Apple Maggot 

 feeds indiscriminately through the pulp of the fruit, burrowing 

 in every direction. The larvae which do the damage are them- 

 selves also different, that of the Codling Moth having six legs 

 while the Apple Maggot is footless.
