  There 
  are 
  no 
  exact 
  data 
  showing 
  that 
  the 
  larvae 
  of 
  Euxoa 
  segeturrit 
  

   Schiff., 
  have 
  injured 
  winter-sown 
  cereals 
  during 
  the 
  last 
  two 
  years, 
  

   but 
  it 
  has 
  been 
  ascertained 
  that 
  these 
  insects 
  occur 
  in 
  the 
  fields 
  of 
  

   potatoes, 
  beet-roots 
  and 
  carrots. 
  As 
  many 
  as 
  twenty 
  larvae 
  were 
  

   sometimes 
  found 
  underneath 
  one 
  root 
  of 
  beet 
  ; 
  carrots 
  were 
  in 
  some 
  

   locaUties 
  injured 
  by 
  them 
  to 
  such 
  a 
  degree 
  that 
  the 
  injury 
  was 
  ascribed 
  

   to 
  hares 
  ; 
  they 
  were 
  found 
  also 
  underneath 
  onions. 
  Species 
  of 
  Cydia 
  

   (Grapholita) 
  are 
  spreading 
  over 
  the 
  country 
  to 
  such 
  a 
  degree 
  that 
  the 
  

   cultivation 
  of 
  peas 
  has 
  become 
  impossible, 
  up 
  to 
  75 
  per 
  cent, 
  of 
  the 
  

   seed 
  being 
  injured 
  by 
  these 
  caterpillars. 
  

  

  Chlorops 
  taeniopus, 
  Mg., 
  was 
  found 
  in 
  1913 
  on 
  barley 
  in 
  the 
  fields 
  

   of 
  the 
  Freidenstein 
  School, 
  5 
  per 
  cent, 
  of 
  the 
  plants 
  being 
  injured 
  

   by 
  this 
  fly. 
  Oscinis 
  frit, 
  L., 
  is 
  frequently 
  found. 
  

  

  With 
  regard 
  to 
  orchards 
  and 
  market-gardens, 
  the 
  following 
  pests 
  are 
  

   mentioned 
  : 
  — 
  Anthonomus 
  pomorum, 
  L., 
  together 
  with 
  Cydia 
  pomonella^ 
  

   L., 
  is 
  very 
  widespread 
  and 
  does 
  great 
  damage. 
  Rhynchites 
  betuli, 
  F., 
  

   is 
  scarce. 
  Pieris 
  brassicae, 
  L., 
  and 
  P. 
  rapae, 
  L., 
  are 
  abundant. 
  Aporia 
  

   crataegi, 
  L., 
  and 
  Vanessa 
  polychloros, 
  L., 
  are 
  seldom 
  found 
  ; 
  Hypono- 
  

   meuta 
  malinellus, 
  Z., 
  occurs 
  in 
  large 
  numbers 
  in 
  some 
  locahties 
  and 
  

   strips 
  the 
  apple 
  trees. 
  Barathra 
  (Mamestra) 
  brassicae, 
  L., 
  proves 
  

   more 
  injurious 
  to 
  cabbage 
  than 
  Pieris 
  brassicae. 
  Nematus 
  ventricosus, 
  

   Kl., 
  is 
  very 
  injurious 
  in 
  some 
  locahties 
  to 
  gooseberries 
  and 
  currants. 
  

   Chortophila 
  brassicae, 
  Bouch., 
  is 
  common. 
  

  

  The 
  following 
  insect 
  pests 
  of 
  forests 
  are 
  reported 
  : 
  — 
  Rhyacionia 
  

   (Evetria) 
  resinella, 
  L., 
  frequently 
  on 
  young 
  pine 
  trees 
  ; 
  Eucosma 
  

   (Grapholita) 
  tedella. 
  Clerk, 
  on 
  firs, 
  especially 
  young 
  plants 
  ; 
  Lymantria 
  

   monacha, 
  L., 
  in 
  large 
  numbers 
  in 
  the 
  forests 
  of 
  Kurland.

  This 
  is 
  a 
  report 
  of 
  work 
  on 
  insect 
  pests 
  done 
  during 
  1913 
  at 
  the 
  

   Station 
  of 
  Kiev 
  by 
  I. 
  S. 
  Ljubomudrov, 
  who 
  investigated 
  the 
  habits 
  

   of 
  various 
  Microlepidoptera 
  of 
  the 
  subfamilies 
  Olethreutinae 
  and 
  

   ToRTRiciNAE 
  ; 
  by 
  I. 
  F. 
  Bay 
  and 
  D. 
  I. 
  Lessovoy, 
  who 
  dealt 
  with 
  the 
  

   pests 
  of 
  grain 
  crops 
  ; 
  and 
  by 
  B. 
  I. 
  Belsky, 
  who 
  studied 
  Byturus 
  tomen- 
  

   tosus, 
  Bjerk. 
  

  

  Recurvaria 
  leucatella, 
  L., 
  was 
  found 
  in 
  spring 
  shoots 
  of 
  apple 
  trees, 
  

   in 
  a 
  short 
  longitudinal 
  mine 
  underneath 
  the 
  bud, 
  causing 
  all 
  the 
  leaves 
  

   on 
  the 
  shoots 
  to 
  wither. 
  Some 
  of 
  these 
  shoots 
  were 
  cut 
  off 
  on 
  the 
  19th 
  

   May 
  and 
  put 
  into 
  water 
  in 
  the 
  laboratory 
  ; 
  the 
  caterpillars 
  grew 
  

   slowly, 
  remaining 
  all 
  the 
  time 
  inside 
  the 
  stem, 
  and 
  at 
  the 
  end 
  of 
  June 
  

   pupated 
  in 
  their 
  mines 
  ; 
  the 
  moths 
  emerged 
  on 
  the 
  12th 
  and 
  13th 
  July. 
  

   On 
  the 
  9th 
  July 
  some 
  small 
  parasitic 
  Hymenoptera 
  issued 
  from 
  one 
  

   shoot. 
  The 
  author 
  remarks 
  that 
  this 
  is 
  the 
  first 
  time 
  that 
  caterpillars 
  

   of 
  Recurvaria 
  leucatella 
  have 
  been 
  found 
  inside 
  the 
  stems, 
  as, 
  according 
  

   to 
  the 
  usual 
  statements, 
  they 
  live 
  inside 
  curled 
  leaves 
  ; 
  only 
  the
