  The 
  author 
  deals 
  with 
  his 
  observations 
  on 
  the 
  habits 
  of 
  Phlyctaenodes 
  

   sticticalis. 
  In 
  order 
  to 
  prevent 
  the 
  females 
  from 
  ovipositing 
  on 
  the 
  

   plantations, 
  fumigation 
  by 
  means 
  of 
  smouldering 
  dung, 
  mixed 
  with 
  

   sulphur, 
  was 
  applied 
  with 
  a 
  certain 
  degree 
  of 
  success. 
  The 
  insects 
  

   were 
  also 
  caught 
  in 
  fermenting 
  molasses, 
  but 
  it 
  was 
  found 
  out 
  that 
  they 
  

   are 
  not 
  attracted 
  by 
  molasses 
  in 
  the 
  same 
  way 
  as 
  Agrotis 
  and 
  Mamestra. 
  

   Oviposition 
  started 
  in 
  the 
  Governments 
  of 
  Charkov 
  and 
  Kiev 
  in 
  the 
  

   middle 
  of 
  June, 
  and 
  took 
  place 
  chiefly 
  on 
  weeds, 
  and 
  less 
  frequently 
  

   on 
  the 
  leaves 
  of 
  sugar-beet, 
  both 
  on 
  fresh 
  and 
  dry 
  leaves. 
  The 
  author 
  

   pays 
  special 
  attention 
  to 
  the 
  plants 
  which 
  serve 
  as 
  food 
  for 
  these 
  

   polyphagous 
  insects, 
  and 
  he 
  gives 
  a 
  long 
  list 
  of 
  them 
  arranged 
  according 
  

   to 
  the 
  system 
  of 
  Professor 
  Vettstein, 
  of 
  Vienna. 
  From 
  this 
  he 
  deduces 
  

   that 
  these 
  pests, 
  belonging 
  to 
  one 
  of 
  the 
  oldest 
  families 
  (Pyralidae) 
  

   select 
  their 
  food 
  mostly 
  from 
  the 
  oldest 
  orders 
  of 
  plants 
  — 
  Fagales 
  and 
  

   Urticales 
  — 
  and 
  those 
  orders 
  which 
  originated 
  from 
  them 
  ; 
  most 
  of 
  the 
  

   plants 
  attacked 
  belonging 
  to 
  the 
  families 
  Chenopodiaceae 
  and 
  

   PapiUonaceae. 
  

  

  A 
  Sphegid 
  wasp, 
  Ceratocolus 
  alatus, 
  Pz., 
  has 
  been 
  observed 
  to 
  

   destroy 
  the 
  moths 
  of 
  P. 
  sticticalis 
  by 
  paralysing 
  them 
  and 
  storing 
  them 
  

   as 
  food 
  for 
  their 
  larvae 
  ; 
  the 
  cocoons 
  of 
  these 
  wasps 
  are 
  more 
  or 
  less 
  

   composed 
  of 
  the 
  wings 
  of 
  Phlyctaenodes. 
  Other 
  species 
  of 
  this 
  genus 
  

   also 
  prey 
  upon 
  Pyralid 
  and 
  Tortricid 
  moths. 
  

  

  The 
  author 
  points 
  out 
  that 
  it 
  is 
  not 
  sufficient 
  to 
  mow 
  down 
  weeds 
  

   round 
  the 
  plantations 
  or 
  on 
  fallow 
  land, 
  but 
  that 
  in 
  order 
  to 
  destroy 
  

   the 
  eggs 
  effectively 
  it 
  is 
  necessary 
  either 
  to 
  spray 
  the 
  weeds 
  before 
  

   mowing 
  with 
  a 
  5-6 
  per 
  cent, 
  solution 
  of 
  barium 
  chloride 
  or 
  with 
  a 
  

   5-10 
  per 
  cent, 
  solution 
  of 
  iron 
  sulphate, 
  or 
  to 
  burn 
  the 
  mowed 
  grass, 
  

   having 
  poured 
  some 
  kerosene 
  over 
  it. 
  

  

  The 
  females 
  do 
  not 
  oviposit 
  on 
  the 
  plants 
  on 
  which 
  they 
  feed, 
  but 
  

   always 
  fly 
  for 
  this 
  purpose 
  to 
  fallow 
  fields, 
  where 
  they 
  lay 
  their 
  eggs- 
  

   mostly 
  on 
  Atriplex, 
  an 
  average 
  of 
  26 
  eggs 
  being 
  found 
  on 
  one 
  plant,, 
  

   this 
  number 
  rising 
  to 
  60 
  in 
  some 
  cases.
