  Egg 
  Plant 
  (Solarium 
  melongena). 
  

  

  Acanthocoris 
  jasciculatus, 
  F. 
  This 
  bug 
  is 
  a 
  serious 
  pest. 
  In 
  many 
  market- 
  

   gardens 
  these 
  useful 
  plants 
  are 
  smothered 
  with 
  it 
  ; 
  the 
  tips 
  of 
  the 
  young 
  shoots 
  wilt 
  

   quickly 
  when 
  heavily 
  infested. 
  It 
  occurs 
  as 
  a 
  minor 
  pest 
  of 
  the 
  chilli 
  (Capsicum 
  sp.). 
  

  

  Cucurbit 
  ace 
  ae. 
  

  

  Dacus 
  vertebratus, 
  Bezzi. 
  The 
  larvae 
  of 
  this 
  fruit-fly 
  are 
  extremely 
  common 
  

   in 
  all 
  varieties 
  of 
  native 
  gourds 
  and 
  cause 
  a 
  large 
  amount 
  of 
  damage. 
  Other 
  food- 
  

   plants 
  are 
  Luffa 
  acutangula 
  and 
  various 
  squashes. 
  Market-gardeners 
  have 
  attempted 
  

   to 
  grow 
  melons 
  and 
  cucumbers, 
  but 
  very 
  few 
  reach 
  maturity 
  owing 
  to 
  the 
  ravages 
  

   of 
  this 
  fly. 
  

  

  Two 
  other 
  species 
  of 
  Dacus 
  also 
  occur 
  in 
  gourds, 
  D. 
  brevistylus, 
  Bezzi, 
  and 
  Dacus 
  

   punctatifrons, 
  Karsch. 
  

  

  Pigeon 
  Pea 
  (Cajanus 
  indicus). 
  

   Rhynchota. 
  

  

  Pseudococcus 
  obtusus, 
  Newst. 
  This 
  insect, 
  one 
  of 
  the 
  commonest 
  Coccids 
  of 
  the 
  

   island, 
  is 
  found 
  in 
  enormous 
  numbers 
  on 
  this 
  useful 
  plant. 
  

  

  Coleoptera. 
  

  

  Tragocephala 
  variegata, 
  Bert. 
  Adults 
  of 
  this 
  Longicorn 
  are 
  prevalent 
  during 
  the 
  

   hot 
  season 
  from 
  October 
  to 
  March. 
  Eggs 
  found 
  in 
  the 
  field 
  in 
  April 
  hatched 
  in 
  

   10 
  days 
  ; 
  larvae 
  have 
  been 
  kept 
  in 
  captivity 
  for 
  3 
  months 
  without 
  pupating 
  ; 
  pupae 
  

   taken 
  in 
  the 
  field 
  produced 
  imagos 
  in 
  12 
  days. 
  The 
  female 
  gnaws 
  a 
  small 
  hole 
  

   in 
  the 
  bark 
  of 
  a 
  lateral 
  branch 
  and 
  there 
  deposits 
  an 
  egg. 
  The 
  larvae 
  feed 
  for 
  a 
  

   short 
  time 
  in 
  this 
  branch, 
  then 
  tunnel 
  down 
  the 
  main 
  stalk, 
  making 
  many 
  vent 
  

   holes 
  during 
  their 
  transit 
  and 
  eventually 
  pupating 
  in 
  a 
  plugged 
  cell 
  low 
  down 
  in 
  

   the 
  trunk 
  or 
  even 
  in 
  the 
  root. 
  A 
  large 
  exit 
  hole 
  denotes 
  the 
  escape 
  of 
  the 
  adult. 
  

   / 
  Lyprops 
  breviusculus, 
  Gerst. 
  Numbers 
  of 
  these 
  beetles 
  have 
  been 
  found 
  feeding 
  

   on 
  the 
  peas. 
  All 
  instars 
  are 
  present 
  in 
  the 
  pods. 
  They 
  are 
  generally 
  found 
  in 
  

   neglected 
  fields 
  where 
  old 
  pods 
  have 
  been 
  left 
  on 
  the 
  trees. 
  

  

  Several 
  species 
  of 
  Meloidae 
  feed 
  on 
  the 
  leaves 
  but 
  are 
  only 
  minor 
  pests. 
  The 
  

   following 
  have 
  been 
  identified 
  ; 
  — 
  Mylabris 
  dicincta, 
  Bert., 
  Mylabris 
  amplectens, 
  

   Gerst., 
  and 
  Coryna 
  ambigua, 
  Gerst. 
  

  

  Lepidoptera. 
  

  

  Marasmarcha 
  atomosa, 
  Wlsm. 
  These 
  small 
  delicate 
  moths 
  have 
  been 
  taken 
  

   towards 
  dusk 
  hoveling 
  around 
  the 
  pods. 
  The 
  characteristic 
  larva, 
  studded 
  with 
  

   spines 
  and 
  hairs 
  radiating 
  from 
  tubercles, 
  feeds 
  through 
  a 
  hole 
  on 
  the 
  pea. 
  The 
  

   pupa 
  closely 
  resembles 
  the 
  larva 
  and 
  is 
  generally 
  found 
  on 
  the 
  outside 
  of 
  the 
  pod. 
  

  

  Deudorix 
  antalus, 
  HopfT. 
  The 
  large 
  flat 
  conspicuous 
  larvae 
  of 
  this 
  butterfly 
  are 
  

   an 
  occasional 
  pest 
  of 
  the 
  pigeon 
  pea. 
  They 
  are 
  voracious 
  feeders 
  and 
  attack 
  the 
  

   seeds 
  in 
  young 
  green 
  pods 
  with 
  avidity, 
  at 
  times 
  causing 
  a 
  considerable 
  amount 
  

   of 
  damage. 
  Pupation 
  takes 
  place 
  in 
  the 
  pod.
