252 APPLE-MIDGE FRUIT HOW AFFECTED BY IT. 



person who enters resolutely upon this work will destroy count- 

 less numbers every hour. But it requires the combined efforts 

 of a multitude of persons, when a district is overrun, to rid it of 

 this pest; and bounties from the public treasury to encourage 

 the destruction of such vermin, might as appropriately be paid, 

 as for the destruction of wolves and other animals which are a 

 public nuisance. 



I have only further to remark that where these insects have 

 abounded, grapes and other choice fruits, which it was earnestly 

 desired to save from destruction, have been effectually protected, 

 by covering the vines and shrubs with millinet or some other 

 similar netting. 



In the interior of ripened and stored apples accelerating their decay, 'whilst 

 the outside remains fair; numerous slender tapering glassy-white 

 worms. 



The Apple midge, Molobrus Mali, new species. 



The common apple worm or larva of the codling moth (Car- 

 pocapsa Pcmonella,) a soft flesh-colored or white worm with a 

 shining tawny yellow head, which feeds upon the seeds and ad- 

 jacent fleshy parts of the apple and perforates a hole in its side 

 through which to make its escape when ready to become a pupa, 

 is the only insect which has been as yet noticed in our country 

 as residing within this fruit. But from having observed apples 

 the cores of which appeared to be depredated upon in a differ- 

 ent manner from that of this worm, I have long entertained the 

 opinion that we have other insects also which spoil this fruit 

 from feeding internally upon it. And I have recently met with 

 one insect of this kind, my investigations of which I here pre- 

 sent. 



Among the apples exhibited at the annual meeting of the 

 State Agricultural Society, February 1856, I noticed one perfo- 

 rated with a hole from which a worm of the codling moth had 

 made its exit. I took this apple at the close of the exhibition 

 and examined it next day. It was a fine large specimen, fair 

 externally and without any blemish except the perforation al- 

 ready mentioned. But on cutting it open almost the whole of 

 its interior was found to be decayed. Its fleshy part was mostly
