  the

   a 
  remedy.

  (Murgantia

  often 
  does 
  great 
  damage 
  in

   and 
  handpicking,

  it 
  is 
  the

  is 
  too 
  costly.

  The 
  following 
  insects 
  are 
  dealt 
  with, 
  beginning 
  with 
  the 
  pests 
  of 
  

   sugar-beets 
  : 
  — 
  Bothynoderes 
  pimctiventris, 
  Germ., 
  appeared 
  very 
  early, 
  

   but 
  in 
  small 
  numbers, 
  and 
  has 
  not 
  done 
  much 
  harm.^The 
  report 
  deals 
  

   with 
  the 
  question 
  of 
  trap 
  trenches 
  round 
  the 
  small 
  fields 
  of 
  peasant 
  

   proprietors, 
  which 
  occupy 
  a 
  not 
  unimportant 
  part 
  of 
  the 
  field, 
  and 
  

   leave 
  less 
  space 
  for 
  cultivation. 
  Smaller 
  trenches 
  wdth 
  more 
  bait-wells 
  

   are 
  suggested. 
  Otiorrhynchus 
  ligustici, 
  L., 
  is 
  injurious 
  both 
  as 
  imago 
  

   and 
  larva, 
  the 
  former 
  damaging 
  the 
  above-ground 
  parts, 
  the 
  larvae 
  

   those 
  below 
  the 
  surface. 
  The 
  chief 
  food-plants 
  of 
  these 
  insects 
  include 
  

   nettles, 
  hops, 
  knotgrass 
  {Polygonum), 
  beet, 
  asparagus, 
  Xanthium, 
  

   lucerne, 
  clover, 
  sainfoin, 
  Melilotus 
  officinalis, 
  beans, 
  peaches 
  (damaged 
  

   by 
  the 
  imago), 
  and 
  vines. 
  The 
  weevils 
  cannot 
  fly 
  and 
  multiply 
  either 
  

   parthenogenetically 
  or 
  sexually. 
  The 
  hibernating 
  larvae 
  were 
  found 
  

   in 
  November 
  and 
  December, 
  1913, 
  underneath 
  roots 
  of 
  red 
  clover 
  in 
  

   the 
  government 
  of 
  Tchernigov. 
  The 
  beetles 
  appear 
  after 
  the 
  13th 
  

   May 
  and 
  in 
  European 
  Russia 
  are 
  found 
  from 
  Finland 
  to 
  Bessarabia, 
  

   the 
  Crimea 
  and 
  Caucasia. 
  The 
  chief 
  remedy 
  consists 
  in 
  trap 
  trenches. 
  

   Psalidium 
  maxillosum, 
  F., 
  was 
  discovered 
  in 
  1912 
  for 
  the 
  first 
  time 
  

   in 
  the 
  government 
  of 
  Kiev, 
  where, 
  as 
  is 
  also 
  the 
  case 
  in 
  Podolia 
  and 
  

   Poltava, 
  it 
  is 
  found 
  in 
  May 
  and 
  June. 
  It 
  also 
  occurs 
  in 
  Hungary, 
  

   Rumania 
  and 
  Bulgaria, 
  where 
  it 
  attacks 
  vines. 
  Some 
  investiga- 
  

   tons 
  conducted 
  at 
  the 
  Station 
  are 
  described, 
  and 
  it 
  is 
  thought 
  that 
  the 
  

   larvae 
  feed 
  on 
  the 
  roots 
  of 
  beets 
  ; 
  the 
  weevils 
  appear 
  in 
  the 
  autumn 
  and 
  

   then 
  hibernate, 
  only 
  one 
  generation 
  per 
  annum 
  being 
  produced. 
  

  

  Chromoderus 
  declivis, 
  Oliv., 
  is 
  seldom 
  found 
  in 
  the 
  government 
  of 
  

   Kiev 
  and 
  then 
  only 
  in 
  small 
  numbers 
  ; 
  last 
  year 
  a 
  specimen 
  was 
  found 
  

   on 
  19th 
  April. 
  It 
  also 
  occurs 
  in 
  Hungary 
  and 
  Siberia 
  ; 
  its 
  life-history 
  

   is 
  not 
  known. 
  Other 
  weevils 
  mentioned 
  are 
  Chromoderus 
  fasciatuSy 
  

   Mull., 
  found 
  in
