﻿THE

  come 
  into 
  houses 
  at 
  times 
  and 
  are 
  not 
  usually 
  noticed 
  as 
  being 
  different 
  

   from 
  the 
  common 
  species. 
  

  

  In 
  the 
  larval 
  stages 
  the 
  

   habits 
  differ. 
  Many, 
  perhaps 
  

   the 
  most, 
  are 
  scavengers, 
  as 
  

   are 
  the 
  muscids; 
  a 
  few^ 
  are 
  

   parasitic, 
  as 
  are 
  the 
  Tachi- 
  

   nids; 
  quite 
  a 
  number 
  feed 
  in 
  

   living 
  vegetation, 
  either 
  in 
  

   roots, 
  as 
  the 
  onion 
  and 
  cab- 
  

   bage 
  maggot, 
  or 
  mine 
  in 
  

   leaves, 
  as 
  in 
  beets. 
  

  

  The 
  root 
  maggots 
  are 
  diffi- 
  

   cult 
  to 
  deal 
  with, 
  and 
  not 
  all 
  

   methods 
  are 
  equally 
  useful 
  in 
  

   all 
  localities. 
  Tobacco, 
  helle- 
  

   bore, 
  kainit, 
  lime 
  with 
  car- 
  

   bolic 
  acid 
  or 
  turpentine 
  have 
  

   all 
  been 
  used 
  as 
  repellants 
  or 
  

  

  destroyers 
  with 
  more 
  or

  Bisulphide 
  of 
  carbon 
  injected 
  into 
  the 
  soil 
  has 
  proved 
  useful 
  in 
  some 
  

   cases, 
  and

  has 
  a

  card 
  surrounding 
  a 
  plant 
  and 
  resting

  the 
  

   surface. 
  The 
  farmer 
  must 
  usually 
  learn 
  by 
  experience 
  the 
  particular 
  

   method 
  most 
  useful 
  in 
  his 
  locality.
