  of 
  the 
  first 
  adult 
  codling 
  moth, 
  that 
  is, 
  about 
  40 
  days 
  before 
  they 
  

   could, 
  under 
  natural 
  conditions, 
  attack 
  the 
  first 
  brood 
  of 
  larvae 
  of 
  the 
  

   moth. 
  This 
  would 
  result 
  in 
  a 
  very 
  small 
  first 
  generation 
  of 
  the 
  

   parasites 
  unless 
  they 
  would 
  attack 
  some 
  other 
  host, 
  since 
  the 
  hibernat- 
  

   ing 
  brood 
  of 
  parasites 
  would 
  have 
  passed 
  the 
  greater 
  portion 
  of 
  their 
  

   adult 
  life 
  before 
  an 
  abundance 
  of 
  codling-moth 
  larvae 
  could 
  be 
  found. 
  

   To 
  determine 
  if 
  Calliephialtes 
  would 
  attack 
  other 
  species 
  of 
  insects, 
  

   larvae 
  of 
  Enarmonia 
  prunivora, 
  Walsh, 
  Euzophera 
  semifuneralis, 
  Walk., 
  

   and 
  Gnorimoschema 
  gallaesolidaginis, 
  Riley, 
  were 
  placed 
  in 
  the 
  

   propagating 
  cages 
  with 
  ovipositing 
  females 
  of 
  the 
  parasite. 
  A 
  larva 
  

   of 
  Enarmonia 
  was 
  parasitised 
  within 
  two 
  days, 
  a 
  diminutive 
  male 
  

   Calliephialtes 
  emerging 
  from 
  the 
  cocoon 
  22 
  days 
  later 
  ; 
  this 
  specimen 
  

   was 
  much 
  smaller 
  than 
  the 
  normal 
  full-grown 
  larva 
  and 
  it 
  is 
  doubtful 
  

   whether 
  Enarmonia 
  would 
  serve 
  in 
  the 
  long 
  run 
  as 
  an 
  alternate 
  host. 
  

   Neither 
  of 
  the 
  two 
  remaining 
  species 
  was 
  parasitised. 
  Codhng 
  moth 
  

   larvae 
  containing 
  the 
  internally 
  parasitic 
  larvae 
  of 
  Ascogaster 
  car- 
  

   pocapsae 
  were 
  readily 
  attacked 
  by 
  Calliephialtes 
  ; 
  this 
  always 
  resulted 
  

   in 
  the 
  death 
  of 
  the 
  earlier 
  parasite 
  and 
  the 
  production 
  of 
  a 
  diminutive 
  

   adult 
  Calliephialtes.

  The 
  Report, 
  which 
  is 
  the 
  first 
  since 
  the 
  entomological 
  department 
  

   became 
  an 
  independent 
  section 
  in 
  April 
  1912, 
  begins 
  with 
  a 
  description 
  

   of 
  the 
  organisation 
  of 
  the 
  section, 
  its 
  laboratory 
  accommodation 
  and 
  

   of 
  its 
  facilities 
  for 
  field 
  work. 
  Tours 
  were 
  made 
  in 
  many 
  localities 
  for 
  

   the 
  investigation 
  of 
  insect 
  pests. 
  

  

  The 
  Deccan 
  grasshopper 
  did 
  considerable 
  damage 
  in 
  the 
  western 
  

   taluks 
  of 
  the 
  Bellary 
  district 
  in 
  1911, 
  and 
  a 
  similar 
  attack 
  was 
  expected 
  

   in 
  1912. 
  Accordingly 
  cultivators 
  were 
  instructed 
  in 
  the 
  use 
  of 
  bag- 
  

   nets, 
  and 
  were 
  informed 
  of 
  the 
  life-history 
  of 
  the 
  insect 
  and 
  the 
  

   preventive 
  measures 
  that 
  may 
  be 
  used. 
  The 
  grasshopper 
  seems 
  to 
  be 
  

   increasing 
  its 
  area 
  of 
  distribution 
  eastwards 
  and 
  southwards 
  from 
  the 
  

   northern 
  and 
  w^estern 
  parts 
  of 
  Bellary 
  ; 
  on 
  first 
  arrival 
  in 
  a 
  new 
  district 
  

   it 
  is 
  little 
  noticed 
  as 
  a 
  rule, 
  being 
  in 
  small 
  numbers, 
  but 
  the 
  insects 
  

   increase 
  rapidly, 
  so 
  that 
  in 
  three 
  or 
  four 
  years 
  they 
  may 
  cause 
  the 
  

   complete 
  destruction 
  of 
  all 
  the 
  dry 
  crops 
  ; 
  after 
  this 
  their 
  power 
  is 
  

   somewhat 
  abated 
  by 
  the 
  increasing 
  efficiency 
  of 
  natural 
  enemies, 
  

   chiefly 
  Cantharid 
  beetles. 
  The 
  attack 
  in 
  Bellary 
  in 
  1912 
  proved 
  after 
  

   all 
  to 
  be 
  slight 
  in 
  the 
  western 
  taluks, 
  but 
  at 
  Beeravalli 
  a 
  few 
  hundred 
  

   acres 
  were 
  found 
  to 
  be 
  heavily 
  infested. 
  Another 
  grasshopper, 
  

   Epacromia 
  dorsalis, 
  w^as 
  reported 
  as 
  attacking 
  young 
  ragi 
  and 
  daincha 
  

   crops 
  in 
  Madura 
  ; 
  the 
  attack 
  was 
  over 
  before 
  steps 
  against 
  it 
  could 
  

   be 
  taken.
