Western yellowstriped
armyworm and beet
armyworm
Identification tip: Young armyworms skeletonize foliage.
|
Green peach aphid
Identification tip: The green peach aphid is
dark green to yellow, without a waxy bloom. Tubercles on
antennae are converging rather than diverging on the potato
aphid.
|
Hornworms
Identification tip: Both species of hornworms have
a large horn on the posterior end of the body.
|
Loopers
Identification tip: Loopers are easily recognized
because they crawl by arching their backs.
|
Lygus
Identification tip: Adults are yellowish, brownish, or greenish
bugs, about 0.3 inch in length, with a conspicuous triangle
in the center of the back that is tinged brown, red, or yellow.
|
Potato aphid
Identification tip: This aphid is much bigger than
the green peach aphid with a more elongate body shape and
is generally found on the terminals of tomato plants later
in the season. It is also considered to be more damaging.
|
Thrips
Identification tip: Thrips are small
insects, about 0.04 inch long. Adults have two pairs
of narrow wings which are fringed with hairs.
|
Tomato bug
Identification tip: Tomato bugs
are slender plant bugs about 1/4 inch in length with
long legs and a green body. Nymphs (right) resemble adults
(left), but are smaller and lack wings.
|
Tomato bug damage
Identification tip: Tomato bug damage results
in reddish rings around petioles and stems which easily break
when contacted.
|
Tomato fruitworm
Identification tip: Newly hatched larvae have black heads and are creamy white with black spots and hairs. More mature larvae (shown here) range from yellowish green to nearly black, have fine white lines along the body and retain the black spots with hairs.
Tomato fruitworm damage.
Identification tip: Larvae enter fruit at the stem end.
|
Tomato pinworm
Identification
tip: This caterpillar feeds on leaves and creates blotch
type mines but causes most of its damage when
it attacks the fruit.
|
Virus symptoms
|
Whiteflies
Identification tip: Whitefly adults are tiny, 0.06
inch long, yellowish insects with white wings.
