INJUEIOUS INSECTS 



THE APPLE-MAGGOT. 

 {Trypeta pomonella, Walsh.) 



Besides the well-known Apple-worm, or Codling-motb, 

 there is in some localities, especially in the older (States, 

 the Apple-maggot. It differs from the Codling-moth in 

 many respects ; the parent insect is not a moth, but one 

 of the two-winged flies. It is not, like the other, an 



Fig. 105. — APPLE-MAGGOT (Trypeta pomoneUa, Walsh.) 

 Perfect Insect ; Larva and its burrows ; Pupa. 



imported insect, but a native which has long inhabited 

 our wild apples and the haws, or fruit of our thorns, and 

 is found in cultivated fruit, here and there, all over the 

 country. Figure 105 shows an infested apple, and the 

 insect in its different stages, tlie perfect fly, with its 

 transparent wings, being shown above, while the maggot 

 and pupa are given below. The excavations in the apple 

 show that the larvae enter at no particular place, and do 

 not, as in the case of the Codling-moth, seek the core. 

 The destruction of the infested fruit by feeding it to 

 pigs, or making it into cider, ai-e among the obvious 

 means of prevention.
