Your Bottom Line

Pod Feeders

The most dangerous of the bunch directly attack soybean yield by damaging developing pods and seeds.

Page 1

Foliage Feeders

Present in almost all soybean fields. Most damage rarely meets economic threshold levels in soybeans before bloom or R1.

Stem Feeders

Stem Feeders

Regularly occur in soybeans. Rarely cause economic damage, with some exceptions.

Corn Earworm

Corn Earworm

Feed first on foliage, later on blooms and pods. Attracted to wide row soybeans with open canopy

Southern Green Stinkbug

Stink Bug Complex

Attracted to fields with developing pods. Suck juices from immature seeds leading to aborted seeds and pod drop.

Fall Armyworm

Armyworm Complex

Beet armyworms indicate presence by feeding on pigweed, Fall armyworms develop on grass before moving to soybeans.

Bean Leaf Beetle

Bean Leaf Beetle

Attracted to early-planted soybeans. Damage usually looks more serious than it is.

Green Cloverworm

Green Cloverworm

Feed on leaves between veins, leaving irregular holes. Rarely an economic pest.

Soybean Looper

Soybean Looper

Heavy populations can strip entire fields of leaves, especially in mid- to late-season in MS.

Vbc Larva Stewart

Velvetbean Caterpillar

Ravenous feeders start at the top of a plant and feed downward for complete defoliation.

Kudzu Bug1

Kudzu Bug

Severe infestations suck down the vigor of the plant by removing moisture and plant nutrients.

Three Cornered Alfalfa Hopper

Three-Cornered Alfalfa Hopper

Damage plants less than 12 in. tall by puncturing/feeding on stems near the soil.
