  This 
  article 
  gives 
  some 
  data 
  as 
  to 
  the 
  number 
  of 
  caterpillars 
  of 
  

   Cydia 
  (Carpocapsa) 
  pomonella 
  caught 
  in 
  trap-belts 
  during 
  experiments 
  

   by 
  the 
  Astrachan 
  Entomological 
  Station 
  between 
  June 
  and 
  August, 
  

   1913. 
  The 
  belts 
  were 
  put 
  on 
  78 
  trees, 
  53 
  of 
  which 
  were 
  apple 
  trees 
  

   and 
  the 
  remainder 
  pears, 
  and 
  were 
  inspected 
  about 
  once 
  a 
  week. 
  

   The 
  total 
  number 
  of 
  caterpillars 
  and 
  pupae 
  collected 
  during 
  these 
  

   inspections 
  was 
  4,980, 
  being 
  an 
  average 
  of 
  about 
  80 
  on 
  each 
  apple 
  tree, 
  

   and 
  28 
  on 
  each 
  pear 
  tree. 
  The 
  number 
  collected 
  was 
  in 
  proportion 
  

   to 
  the 
  harvest 
  yielded 
  by 
  the 
  respective 
  trees 
  and 
  therefore 
  the 
  necessity 
  • 
  

   of 
  putting 
  trap-belts 
  both 
  on 
  the 
  trunk 
  and 
  on 
  some 
  of 
  the 
  thicker 
  

   branches 
  of 
  trees 
  which 
  promise 
  a 
  heavy 
  yield, 
  is 
  urged.

  of 
  tomatoes 
  which

   young

  Gryllotalpa

  The

  This 
  book 
  is 
  intended 
  to 
  serve 
  as 
  a 
  manual 
  to 
  the 
  agriculturists 
  of 
  

   Turkestan 
  and 
  gives 
  general 
  information 
  on 
  insects, 
  their 
  life- 
  histories, 
  

   enemies 
  and 
  diseases, 
  remedies

  them, 
  the

  with

   Sixty-four 
  species 
  of 
  insects 
  are 
  described, 
  divided 
  into 
  pests 
  of 
  general 
  

   agriculture 
  and 
  those 
  of 
  orchards, 
  and 
  classified 
  according 
  to 
  the 
  

   nature 
  of 
  the 
  injury 
  done. 
  

  

  Insects 
  injuring 
  roots 
  include 
  Polyphylla 
  adspersa, 
  Motsch., 
  the 
  

   larvae 
  of 
  which 
  are 
  most 
  serious 
  pests 
  of 
  fruit 
  nurseries, 
  gnawing 
  the 
  

   roots 
  of 
  young 
  trees. 
  They 
  are 
  usually 
  found 
  in 
  company 
  with 
  

   Polyphylla 
  tridentata, 
  Keitt. 
  These 
  chafers
