4. Codling moth
Damage
• damages quince fruit
directly by boring into fruit.
Larvae either “sting” fruit,
boring only a short distance
into the flesh, or bore into
the core of a fruit and
consume the seed cavity.
Codling moth only develops
between temperatures of
50°F to 88°F.

5. Twospotted Spider mites
Damage
• appear on fruit leaves at the bottom of the
canopy after warmer weather begins, then
gradually spread throughout the rest of the
canopy. Mites only feed on leaves, but affect
fruit by reducing photosynthesis and
defoliating trees. Pre-harvest defoliation
results in smaller fruit, while postharvest
defoliation can affect the following year’s
fruit. In both cases defoliation can result in a
late fall bloom and dramatically reduce
flowering in the following spring. Twospotted
spider mites can be effectively controlled by
other beneficial insects & mites. If
insecticides are used to prevent other pests
beneficial insect populations can also be
reduced, resulting in spider mite infestations

6. Aphids
Symptoms
• The black and green aphids,
or plant-lice, are often very
troublesome.
Aphids appear in immense
numbers on the young and
tender shoots of trees, and
bysucking their juices check or
enfeeble the growth. They are
the milch-cows of ants, which
are usually found very busy
among them.
