﻿found 
  by 
  Kurdjumov 
  on 
  colonies 
  of 
  Aphis 
  crataegi, 
  Kalt., 
  which 
  they 
  

   possibly 
  also 
  destroy. 
  The 
  egg 
  stage 
  of 
  this 
  predator 
  lasts 
  5-6 
  days, 
  its 
  

   larval 
  stage 
  22-25 
  days, 
  propupa 
  1-2 
  days, 
  and 
  pupa 
  4-5 
  days, 
  on 
  the 
  

   average. 
  This 
  Thrips 
  pierces 
  through 
  all 
  the 
  eggs 
  of 
  the 
  heap, 
  thus 
  

   arresting 
  their 
  further 
  development, 
  and 
  then 
  feeds 
  on 
  them, 
  other- 
  

   wise 
  it 
  would 
  not 
  be 
  able 
  to 
  accomplish 
  its 
  development, 
  as 
  the 
  eggs 
  

   of 
  the 
  host 
  hatch 
  in 
  12-13 
  days. 
  All 
  these 
  parasites 
  together 
  destroy 
  

   some 
  64'4 
  per 
  cent, 
  of 
  eggs 
  of 
  S. 
  squalidus 
  ; 
  a 
  table 
  showing 
  the 
  per- 
  

   centage 
  infested 
  by 
  each 
  of 
  them 
  during 
  the 
  investigations 
  of 
  1913 
  is 
  

   given 
  ; 
  all 
  of 
  them 
  attack 
  also 
  the 
  eggs 
  of 
  Eudipnus 
  micans. 
  

  

  The 
  author 
  then 
  deals 
  with 
  remedies 
  and 
  first 
  describes 
  those 
  applied 
  

   by 
  some 
  fruit-growers 
  in 
  the 
  government 
  of 
  Taurida. 
  These 
  consist 
  

   of 
  trenches, 
  usually 
  with 
  straight 
  walls, 
  dug 
  round 
  the 
  trees, 
  or 
  of 
  

   conical 
  heaps 
  of 
  earth 
  round 
  the 
  trunks, 
  covered 
  with 
  fine 
  sand 
  and 
  

   surrounded 
  by 
  a 
  trench. 
  None 
  of 
  these 
  obstacles 
  seem 
  very 
  effective 
  

   in 
  preventing 
  the 
  beetles 
  shaken 
  off 
  the 
  trees 
  from 
  getting 
  back 
  to 
  

   them. 
  Other 
  appliances 
  are 
  more 
  fully 
  described 
  in 
  the 
  report 
  of 
  

   the 
  Entomological 
  Station 
  of 
  Kiev 
  for 
  1912 
  [see 
  this 
  Review, 
  Ser.

   pp. 
  397.] 
  Shaking 
  down 
  the 
  weevils 
  on 
  to 
  sheets 
  was 
  also 
  tried 
  at 
  the 
  

   station 
  of 
  Poltava 
  during 
  the 
  investigations 
  in 
  1911 
  and 
  the 
  results 
  

   obtained, 
  as 
  shown 
  by 
  two 
  tables, 
  although 
  not 
  conclusive, 
  are 
  con- 
  

   sidered 
  useful. 
  Picking 
  out 
  specimens 
  of 
  ladybirds 
  which 
  may 
  get 
  on 
  

   the 
  cloth, 
  before 
  destroying 
  the 
  insects 
  shaken 
  down, 
  is 
  suggested. 
  

   The 
  remedy 
  most 
  recommended 
  is 
  the 
  use 
  of 
  belts 
  of 
  American 
  tangle- 
  

   foot. 
  The 
  author 
  gives 
  several 
  tables 
  relating 
  to 
  the 
  experiments 
  in 
  

   1912 
  and 
  1913, 
  which 
  all 
  show 
  the 
  excellent 
  results 
  obtained 
  by 
  this 
  

   method. 
  An 
  adhesive 
  made 
  from 
  a 
  recipe 
  suggested 
  by 
  Mokrzecki 
  is 
  

   also 
  very 
  effective 
  : 
  — 
  1 
  lb. 
  of 
  castor 
  oil 
  boiled 
  with 
  J 
  lb. 
  of 
  resin 
  ; 
  if 
  

   correctly 
  prepared 
  this 
  is 
  as 
  good 
  as 
  tangle-foot. 
  The 
  author 
  agrees 
  

   that 
  adhesive 
  belts 
  serve 
  rather 
  to 
  drive 
  away 
  the 
  insects, 
  as 
  it 
  is 
  very 
  

   seldom 
  that 
  beetles 
  are 
  caught 
  by 
  them. 
  Should 
  there 
  be 
  any 
  fruit 
  

   bushes 
  or 
  vines 
  in 
  the 
  orchard, 
  care 
  must 
  be 
  taken 
  to 
  protect 
  them 
  

   from 
  the 
  beetles 
  by 
  means 
  of 
  trenches, 
  and 
  the 
  insects 
  must 
  be 
  collected 
  

   from 
  the 
  trenches 
  as 
  well 
  as 
  from 
  the 
  bushes.

  A 
  detailed 
  description 
  is 
  given 
  of 
  the 
  respiratory 
  system 
  of 
  Mono- 
  

   phlebus

  Green, 
  var. 
  octocaudata. 
  Green, 
  which 
  differs 
  from 
  

   the 
  majority 
  of 
  Coccids 
  in 
  having 
  in 
  addition 
  to 
  the 
  meso- 
  and 
  meta- 
  

   thoracic 
  pairs, 
  seven 
  pairs 
  of 
  dorsal 
  abdominal 
  spiracles. 
  This 
  species 
  

   is 
  found 
  on 
  mango, 
  jack 
  fruit 
  and 
  species 
  of 
  Ficus 
  in 
  India, 
  but 
  as 
  its 
  

   life-history 
  is 
  comparatively 
  long, 
  it 
  is 
  rarely 
  a 
  pest 
  ; 
  climatic 
  con- 
  

   ditions 
  govern 
  the 
  production 
  of 
  large 
  numbers 
  of 
  the 
  individuals, 
  so 
  

   that 
  outbreaks 
  are 
  irregular.
