  Oats 
  have 
  suffered 
  from 
  Cecidomyia 
  avenae 
  in 
  Morbihan. 
  In 
  the 
  

   department 
  of 
  Gers, 
  maize 
  was 
  seriously 
  attacked 
  by 
  Pyrausta 
  nuhilalis 
  

   and, 
  in 
  a 
  lesser 
  degree, 
  by 
  Aphis 
  euonymi. 
  Lucerne 
  was 
  badly 
  injured 
  

   by 
  Colaspidema 
  atrum 
  at 
  Deux-Sevres 
  in 
  Tarn-et-Garonne 
  ; 
  this 
  

   pest 
  was 
  also 
  reported 
  from 
  the 
  Bouches-du-Rhone, 
  Drome, 
  Basses- 
  

   Alpes, 
  Aude 
  and 
  Lot-et-Garonne. 
  In 
  Tarn-et-Garonne, 
  the 
  seed 
  

   crops 
  of 
  clover 
  were 
  devoured 
  by 
  the 
  larvae 
  of 
  Apion 
  apricans. 
  In 
  

   May, 
  OtiorrhyncJius 
  ligustici 
  caused 
  much 
  damage 
  to 
  sown 
  seed 
  in 
  

   Beuce. 
  Feytaud 
  noticed 
  Hylastinus 
  obscurus 
  larvae 
  injuring 
  clover 
  

   in 
  the 
  Gironde. 
  Aphis 
  euonymi 
  has 
  proved 
  injurious 
  to 
  beetroot 
  in 
  

   many 
  districts, 
  especially 
  in 
  the 
  North 
  and 
  in 
  Herault, 
  as 
  also 
  

   were 
  Haltica 
  and 
  the 
  larvae 
  of 
  Cleonus 
  mendicus 
  in 
  Herault 
  and 
  Lixus 
  

   scabricollis 
  at 
  Montpellier. 
  Phthorimaea 
  operculella, 
  the 
  potato 
  tuber 
  

   moth, 
  is 
  still 
  limited 
  to 
  some 
  communes 
  south 
  of 
  the 
  Maures. 
  The 
  

   hop 
  aphis, 
  Phorodon 
  humuli, 
  has 
  again 
  seriously 
  damaged 
  the 
  hopfields 
  

   in 
  the 
  North 
  in 
  spite 
  of 
  repeated 
  spraying 
  with 
  tobacco 
  extract 
  ; 
  this 
  

   treatment 
  has, 
  however, 
  proved 
  more 
  eflB.cacious 
  in 
  the 
  Dijonnais 
  

   and 
  Cote-d'Or. 
  In 
  the 
  same 
  region 
  the 
  red 
  spider, 
  Tetranychus 
  telarius, 
  

   does 
  much 
  harm, 
  and 
  unfortunately 
  many 
  growers 
  consider 
  it 
  to 
  be 
  

   beneficial 
  as 
  its 
  appearance 
  generally 
  coincides 
  with 
  the 
  disappearance 
  

   of 
  the 
  aphids. 
  An 
  outbreak 
  of 
  Pier 
  is 
  caterpillars 
  was 
  reported 
  from 
  

   Meurthe-et-Moselle. 
  In 
  Finistere, 
  cabbages 
  and 
  other 
  Cruciferae 
  

   have 
  suffered 
  much 
  from 
  Haltica 
  and 
  in 
  the 
  Loire 
  Valley 
  the 
  asparagus 
  

   beetle, 
  Crioceris 
  asparagi, 
  has 
  done 
  much 
  harm, 
  though 
  arsenic 
  or 
  

   nicotin 
  sprays 
  have 
  proved 
  successful 
  in 
  many 
  localities. 
  Mole- 
  

   crickets 
  have 
  been 
  troublesome 
  in 
  the 
  important 
  market-gardens 
  of 
  

   the 
  Pyrenees- 
  Orientales. 
  In 
  the 
  same 
  department, 
  in 
  Tarn-et- 
  

   Garonne 
  and 
  in 
  the 
  Var, 
  artichokes 
  have 
  suffered 
  from 
  Gortyna 
  ochracea. 
  

   In 
  Ardeche, 
  Depressaria 
  marcella 
  still 
  does 
  some 
  injury 
  to 
  fennel 
  and 
  

   seed 
  carrots. 
  Damage 
  has 
  been 
  done 
  in 
  the 
  Var 
  by 
  the 
  carrot 
  fly 
  

   and 
  in 
  Dordogne 
  by 
  the 
  celery 
  fly, 
  Acidia 
  heraclei. 
  Hylemyia 
  antiqua, 
  

   Meig., 
  the 
  onion-fly, 
  has 
  caused 
  severe 
  loss 
  in 
  the 
  gardens 
  between 
  

   Dijon 
  and 
  Saint- 
  Jean-de-Losne. 
  In 
  Gers, 
  peas 
  have 
  suffered 
  from 
  the 
  

   attacks 
  of 
  a 
  butterfly 
  Lampides 
  boetica, 
  the 
  caterpillar 
  of 
  which 
  develops 
  

   inside 
  the 
  pods. 
  Cydia 
  (Grapholita) 
  pisana 
  also 
  attacked 
  this 
  crop, 
  

   but 
  less 
  extensively 
  than 
  in 
  the 
  previous 
  year. 
  Thrips 
  tabaci, 
  Lind., 
  

   has 
  proved 
  very 
  injurious 
  to 
  leeks 
  near 
  Mans 
  and 
  in 
  the 
  Croissy-sur-Seine 
  

   region. 
  Another 
  Thrips, 
  Physapus 
  pisivora, 
  Westw. 
  (P. 
  robusta, 
  Uzel) 
  

   injured 
  peas 
  at 
  the 
  Chesnoy 
  Agricultural 
  School, 
  this 
  being 
  the 
  first 
  time 
  

   it 
  appears 
  to 
  have 
  been 
  reported 
  in 
  France 
  as 
  causing 
  injury. 
  In 
  the 
  

   case 
  of 
  orchards, 
  Schizoneura 
  lanigera 
  has 
  increased 
  this 
  year 
  in 
  many 
  

   districts, 
  particularly 
  near 
  Paris, 
  in 
  the 
  Orleannais, 
  Anjou, 
  Cote-d'Or 
  

   and 
  several 
  southern 
  departments, 
  such 
  as 
  the 
  Pyrenees- 
  Orientales 
  

   and 
  Var. 
  Damage 
  done 
  by 
  Hyponomeuta 
  has 
  been 
  reported 
  from 
  

   the 
  Sarthe, 
  Eure, 
  Seine-Inferieure 
  and 
  Puy-de-D6me. 
  Anthonomus 
  

   pomorum 
  has 
  been 
  injurious 
  in 
  the 
  departments 
  of 
  Sarthe, 
  Loire, 
  

   C6tes-du-Nord, 
  Puy-de-D6me. 
  In 
  this 
  last 
  department, 
  the 
  cater- 
  

   pillars 
  of 
  Cheimatobia 
  have 
  been 
  successfully 
  combated 
  by 
  " 
  sticky
