  As 
  the 
  results 
  of 
  observations 
  and 
  experiments 
  on 
  the 
  beetroot 
  

   aphis 
  {A. 
  euonymi, 
  F.), 
  the 
  authors 
  have 
  shown 
  that 
  the 
  fertilised 
  eggs 
  

   laid 
  in 
  the 
  autumn 
  on 
  the 
  bean 
  (the 
  intermediate 
  host 
  plant) 
  do 
  not 
  

   hatch, 
  whereas 
  they 
  hatch 
  normally 
  on 
  Euonymus 
  europaeus 
  (spindle 
  

   tree), 
  the 
  principal 
  host 
  plant. 
  In 
  the 
  second 
  place, 
  if 
  the 
  larvae 
  

   hatching 
  from 
  these 
  eggs 
  are 
  placed 
  on 
  the 
  leaves 
  of 
  the 
  beetroot 
  they 
  

   do 
  not 
  attempt 
  to 
  feed 
  on 
  it. 
  It 
  is 
  thought 
  that 
  the 
  first 
  generation 
  

   of 
  larvae 
  are 
  not 
  adapted 
  to 
  feed 
  on 
  plants 
  other 
  than 
  those 
  on 
  which 
  

   they 
  hatch, 
  but 
  that 
  later 
  generations 
  gradually 
  acquire 
  this 
  

   adaptability.

  The 
  author 
  says 
  that 
  the 
  information 
  supplied 
  by 
  his 
  calendar 
  is 
  

   specially 
  calculated 
  for 
  the 
  government 
  of 
  Taurida, 
  but 
  may 
  also 
  

   be 
  useful 
  for 
  other 
  localities. 
  He 
  indicates 
  the 
  work 
  which 
  must 
  be 
  

   undertaken 
  each 
  month 
  in 
  orchards 
  to 
  protect 
  the 
  trees 
  from 
  insect 
  

   pests 
  and 
  fungoid 
  diseases. 
  The 
  methods 
  of 
  preparation 
  of 
  insecticides 
  

   and 
  fungicides, 
  and 
  various 
  sprayers 
  and 
  other 
  appliances 
  are 
  described 
  

   and, 
  in 
  many 
  instances, 
  figured. 
  

  

  In 
  February, 
  special 
  attention 
  is 
  directed 
  to 
  the 
  eradication 
  of 
  

   winter 
  nests 
  of 
  Aporia 
  crataegi 
  and 
  Euproctis 
  chrysorrhoea, 
  while 
  in 
  

   the 
  second 
  half 
  of 
  this 
  month 
  and 
  in 
  March 
  and 
  April, 
  steps 
  must 
  

   be 
  taken 
  against 
  various 
  Rhynchites. 
  The 
  month 
  of 
  May 
  sees 
  the 
  

   beginning 
  of 
  the 
  fight 
  against 
  Hyponomeuta 
  malinellus 
  and 
  Cydia 
  

   {Carpocapsa) 
  pomonella 
  ; 
  in 
  June 
  and 
  July, 
  bait 
  belts 
  against 
  the 
  

   latter 
  and 
  spraying 
  with 
  djipsin 
  against 
  Malacosoma 
  neustria 
  and 
  

   Lymantria 
  dispar 
  must 
  be 
  applied 
  ; 
  in 
  August 
  and 
  September 
  remedies 
  

   against 
  Cydia 
  pomonella, 
  Choreutis 
  parialis, 
  and 
  Pseudococcus 
  vitis 
  

   are 
  urged. 
  In 
  October, 
  November 
  and 
  December, 
  Cheimatobia 
  brumata 
  

   and 
  Hibernia 
  defoliaria 
  emerge 
  and 
  oviposit 
  on 
  the 
  trees, 
  sticky 
  belts 
  

   being 
  recommended 
  as 
  a 
  remedy. 
  These 
  insects 
  appear 
  in 
  the 
  Crimea 
  

   on 
  about 
  28th 
  November, 
  in 
  Central 
  Russia 
  at 
  the 
  beginning 
  of 
  

   October, 
  and 
  in 
  South 
  Russia 
  at 
  the 
  beginning 
  of 
  November. 
  These 
  

   months 
  are 
  also 
  suitable 
  for 
  beginning 
  the 
  destruction 
  of 
  the 
  eggs 
  

   of 
  Lymantria 
  dispar 
  and 
  of 
  pupae 
  of 
  Clysia 
  {Cochylis) 
  ambiguella. 
  

  

  In 
  December 
  and 
  January, 
  fruit 
  trees 
  ought 
  to 
  be 
  cleared 
  of 
  branches 
  

   injured 
  by 
  Scolytus 
  rugulosus 
  ; 
  the 
  larger 
  branches, 
  which 
  it 
  would 
  

   be 
  a 
  pity 
  to 
  cut 
  off, 
  can 
  be 
  smeared 
  with 
  carbolineum 
  and 
  lime 
  ; 
  the 
  

   collection 
  of 
  winter 
  nests 
  of 
  Euproctis 
  chrysorrhoea 
  and 
  Aporia 
  crataegi 
  

   can 
  be 
  proceeded 
  with.
