3. Prionus Root Borer (Prionus
californicus)
 Larvae will chew deep
furrows in the roots (Fig. 3),
often causing severe
reduction in a tree’s ability to
take up water and
nutrients. The feeding injury
is often associated with rot
and decay, particularly in wet
soils. The colonization of
feeding wounds by soil
microbes will compound the
damage caused by larval
tunneling. Larvae feeding in
the crown form spiraling
furrows which girdle the
crown and upper roots (Fig.
4)
(Fig. 3) Furrows in sweet cherry
roots made by prionus larvae.

californicus)

cherry tree showing circular pattern of prionus
tunnels.

5. Peach twig borer
Anarsia lineatella
 Death of shoot tips;
feeding damage to
fruit, usually at stem
end; larvae are dark
brown and white
with a black head;
adult insect is a
gray-brown moth
Symptoms
Peach twig borer

6. Aphids (Black cherry aphid)
Myzus cerasi
 Small soft bodied insects
on underside of leaves
and/or stems of plant
which are shiny and black
in color; if aphid infestation
is heavy it may cause
leaves to yellow and/or
distorted, necrotic spots on
leaves and/or stunted
shoots; aphids secrete a
sticky, sugary substance
called honeydew which
encourages the growth of
sooty mold on the plants
Symptoms
Aphid colony on sour cherry

7. Western cherry fruit fly
Rhagoletis indifferens
 Fruit mushy and
contains a single
white maggot; adult
insect is a fly with a
black body and white
bands on the
abdomen and a
distinctive dark
banded pattern on
their wings
Symptoms

8. Spider mites (e.g. Two-spotted spider mite)
Tetranychus urticae
 Leaves stippled with
yellow; leaves may appear
bronzed; webbing covering
leaves; mites may be
visible as tiny moving dots
on the webs or underside
of leaves, best viewed
using a hand lens; usually
not spotted until there are
visible symptoms on the
plant; leaves turn yellow
and may drop from plant
Symptoms
Cherry fruit fly adult
