  DECIDUOUS 
  FRUIT 
  INSECTS 
  AND 
  INSECTICIDES. 
  

  

  DESTRTJCTIVENESS 
  OF 
  THE 
  LARVA. 
  

  

  As 
  indicated 
  under 
  the 
  caption 
  dealing 
  with 
  the 
  character 
  of 
  

   injury, 
  a 
  single 
  larva 
  of 
  the 
  first 
  brood 
  may 
  destroy 
  almost 
  an 
  entire 
  

   cluster 
  about 
  the 
  time 
  the 
  grapes 
  are 
  in 
  bloom 
  (see 
  fig. 
  5) 
  . 
  For 
  some 
  

   time 
  after 
  blooming 
  a 
  larva 
  is 
  capable 
  of 
  destroying 
  several 
  berries 
  

   or 
  even 
  a 
  large 
  portion 
  of 
  the 
  cluster 
  by 
  attacking 
  the 
  stem. 
  When 
  

   berries 
  are 
  attacked 
  after 
  they 
  have 
  attained 
  the 
  size 
  of 
  a 
  pea, 
  how- 
  

   ever, 
  rarely 
  more 
  than 
  two 
  or 
  three 
  are 
  destroyed 
  by 
  a 
  single 
  larva. 
  

   Yet 
  this 
  restriction 
  in 
  the 
  number 
  of 
  berries 
  injured 
  by 
  the 
  indi- 
  

   vidual 
  larva 
  is 
  doubtless 
  more 
  than 
  offset 
  by 
  the 
  great 
  increase 
  in 
  

   the 
  number 
  of 
  larvae 
  of 
  the 
  second 
  brood, 
  which 
  are 
  not 
  infrequently

  curculio

  Adult, 
  or 
  beetle, 
  from

  head, 
  antenna, 
  and 
  

   beak 
  of 
  same,

  c, 
  adult, 
  from 
  side; 
  d, 
  larva, 
  from 
  above; 
  e, 
  same, 
  from

  f, 
  pupa, 
  from 
  

   below. 
  All 
  much 
  enlarged. 
  (From 
  Farmers' 
  Bulletin 
  284.) 
  

  

  present 
  in 
  sufficient 
  numbers 
  to 
  destroy 
  nearly 
  all 
  of 
  the 
  berries 
  in 
  

   the 
  cluster, 
  as 
  is 
  shown 
  in 
  Plate 
  VI, 
  figure 
  1. 
  From 
  these 
  clusters 
  

   all 
  the 
  infested 
  berries 
  had 
  been 
  removed 
  previous 
  to 
  taking

  OTHER 
  INSECTS 
  WHOSE 
  INJURY 
  TO 
  GRAPE 
  BERRIES 
  RESEMBLES 
  

   THAT 
  CAUSED 
  BY 
  THE 
  LARVA 
  OF 
  THE 
  GRAPE-BERRY 
  MOTH. 
  

  

  The 
  only 
  other 
  insect 
  attacking 
  the 
  berries 
  of 
  the 
  grape 
  whose 
  

   injury 
  to 
  the 
  fruit 
  closely 
  resembles 
  that 
  of 
  the 
  grape-berry 
  moth 
  is 
  

   the 
  grape 
  curculio, 
  Craponius 
  inxqualis 
  Say. 
  This 
  insect, 
  however 
  

   (see 
  fig. 
  8, 
  a), 
  is 
  one 
  of 
  the 
  snout-beetles 
  or 
  curculios. 
  Its 
  injury 
  to 
  

   the 
  grape 
  berry 
  is 
  similar 
  to 
  that 
  of 
  the 
  plum 
  curculio 
  upon 
  the 
  plum 
  

   and 
  other 
  tree 
  fruits. 
  The 
  grape 
  curculio 
  punctures 
  the 
  skin 
  of 
  the
