pomonella is an insect that primarily infests
apples, pears, English walnuts and rarely

Life Cycle of Codling Moths
The Codling Moth develops through four stages
eggs, larva, pupa and adult moth. The full-grown
larva develops into an adult moth during the
winter inside a silken cocoon, pupating on tree
trunks under the bark, in the soil or on debris
under the tree. The rate of development of the
larva inside the cocoon proceeds more rapidly
during warmer weather and climates.

Life Cycle of Codling Moths
Mating of Codling Moths transpire a few days
after the emergence of the full-grown insect from
the cocoon, which follows impregnation and the
laying of eggs. The tendency of laying eggs
increases as the temperature increases above 620F
during the night

Identification of Codling Moths
A full-grown adult Codling Moth measures about ½
to ¾ inch long with spotted gray wings with brown
tips, which shroud its body. The larvae are white
to light pink colour caterpillar-like worms
with dark brown heads. The instar larva is 1/10
inches while a full-grown larva is ½ to ¾ inches.
The larval stage is followed by the pupating
stage, where the larva creates a cocoon and
pupates through winter.

Controlling Codling Moths
If left unmanaged, Codling Moth larvae can cause
extensive damage, often infesting 20-90 of the
fruit. The extension of the damage is often
dependent on variety and location of the trees.
Codling Moths can be difficult to control if the
population has been allowed to build up over one
or two seasons. It seems more pragmatic to manage
a smaller Codling Moth population than
suppressing a dense population.

removal and destruction of infested trees and
fruits. The bagging method has proven effective
to be used alone for higher population, although
it could be regarded as time-consuming.  This
method should be implemented when the fruit is
about ½ to 1 inch in diameter.
