Diabrotica undecimpunctata
Diabrotica balteata
Symptoms
• Stunted seedling; damaged
leaves, stems and/or petioles;
reduced plant stand; plants
may exhibit symptoms of
bacterial wilt; scars on fruit
caused by beetle feeding
damage; adult beetles are
brightly colored with either a
green-yellow background and
black spots or alternating
black and yellow stripes
• Cause
• Insect
Pumpkin plant infested with
cucumber beetles
5. Squash vine borer
Melittia cucurbitae

vines or at base of petioles;
green frass (insect
excrement) visible around
holes
• Cause
• Insect
6. Squash bug
Anasa tristis
Symptoms
• Speckled leaves which turn yellow

7. Armyworms (Beet armyworm, Western striped armyworm, etc.)
Spodoptera exigua
Spodoptera praefica
Symptoms
• Singular, or closely grouped circular to
irregularly shaped holes in foliage;
heavy feeding by young larvae leads to
skeletonized leaves; shallow, dry
wounds on fruit; egg clusters of 50-150
eggs may be present on the leaves; egg
clusters are covered in a whitish scale
which gives the cluster a cottony or
fuzzy appearance; young larvae are pale
green to yellow in color while older
larvae are generally darker green with a
dark and light line running along the
side of their body and a pink or yellow
underside

• Cause
• Insect
9. Flea beetles Epitrix spp. Systena spp
