  ,_'_   wings, as is common in the family, appear rather squarely cut off l
  ~‘l.       < at the ends, and measure from tip to tip about three-fourths of an \
  inch; they are marked with cross-lines of gray and brown, and at

  <_~ The moths appear about the trees when these are blossoming `
  or a little later and place their minute eggs singly as soon as the
  l fruit sets. The well known apple worms hatch from these eggs and .
  l gnaw their way into the heart of the apple, often utterly destroy-
  ing and causing them to fall to the ground when small, but some- _
  _ times leaving no outward evidence of. their presence except the mass t
  of dejecta which they cast outlof their burrows. When fully grown
  the larvae leave the apples, generally coming out of the side, and
  pupate in the silken cocoons under loose lbark near the base of the
  trunk of the tree, or else under loose rubbish on the ground beneath.
  X More than one brood develops at this latitude during a season.
    V The insect is so well known as not to call for further description.
    We have no other insect attacking the fruit in precisely the same
  § manner. The plum curculio sometimes gouges the skin and causes
      fruit to become knotty and distorted. This it is likely to do only
    l when plum trees grow near apple, and as plums are not very much
  1 grown in Kentucky, the injury is not of great consequence, Still
    another eurculio known as the Apple Gurculio (Amfltonemus
   ;  l _quacl¢·1Zgriblms) occurs in the State and bores round holes in the
  fruit, but has never been known to do mischief sufficient to call
  for treatment. It is a native insect, originally attacking the native · l
  l hawthorn and crab-apple fruit.
    · Remedial Treatment.
    The treatment for codling moth injury very generally adopted
    after much experiment is spraying the trees with Paris green or
  { arscnatc of lead mixtures immediately after the petals fall from
    y the blossoms, so as to destroy the youngworms as soon as hatched
    . and before they reach the interior of- fruit. The experiments made
  ° by this Division in Hardin County in the spring of 1907, indicate
  . that nothing is to bc gained by spraying before the petals Ifall,
    while experiments made by others have shown that the tender stigma
  of the blossom is likely to be damaged by sprays so as to prevent
