Reports to the Board of Agricttltttre. 21 



Small dipterous maggots have also been recorded — possibly the 

 larvffi of the Apple Fruit Fly {Trypeta pomondla), an introduced pest. 



The larvie of the above can be told as follows : — 



(a) Codling ^laggot, pink, with six jointed legs in front, four 

 pairs of prolegs in the middle of the body, and an anal pah*. 



(h) Weevil ^Maggots, white, footless, more or less curved, and with 

 a wrinkled skin. 



(c) Sawfly Maggot, white, six jointed legs in front, more than four 

 pairs of fleshy prolegs. 



{d) Fruit Fly Maggot, white, footless, not curved, small. 



Maggots in Imported Apples. 



Some larvie sent by a correspondent to the Board of Agricultm-e 

 from Smithfield Market, Manchester, proved to be those of the Codling 

 Moth {Carpocapsa 'pomonclla). 



The correspondent pointed out the danger of constant fresh 

 importations of this pest from aljroad. Some observations have been 

 privately made which couflrm this report. 



The Codling Moth has been distributed to countries where it was 

 formerly unknown in the way described by the correspondent of the 

 Board. If large numbers occur alive, as recorded, there is undoubtedly 

 much harm being done, and this may account for tlie great increase of 

 this apple pest during recent years, which in some cases during the 

 past season has completely ruined tlie apple crop. 



As the pest is very abundant in America, and probably the 

 unsound apples are shipped to the English market, some steps should 

 be taken, if it proves to be a general rule, to safeguard the apple 

 growers of this country by similar means to those employed in 

 Tasmania. 



Apple barrels have been examined and numbers of Codling 

 Maggots \\QXQ been found. These get distributed over the country, 

 and cannot but help increase this pest in our orchards. 



The maggot in Lisbon apples may prove to be one of the fruit flies 

 iTrijpda or Ccratitis).
