Biology

Ecdytolopha fabivora completes several generations per year. In areas where host plants are available year-round, adults may be present at any time.
Females lay eggs on the leaves, petioles, stems, flowers, and pods, of soybean; oviposition behavior varies with plant age. Larvae tunnel into the petioles, stems, or pods, sometimes causing considerable damage. Larvae may also feed on terminals and flowers. Pupation occurs in cocoons at the larval feeding site.
Larval damage is characterized by stunted plants, pod loss, or complete plant death in the case of tunnelling in the main stem.
Host plants
Ecdytolopha fabivora is a pest of beans (lima beans, string beans, soybeans) in Central and South America.
Family | Genus/species | Common name |
Fabaceae | Glycine max (L.) Merr. | soybean |
Fabaceae | Phaseolus lunatus L. | sieva (lima) bean |
Fabaceae | Phaseolus vulgaris L. | kidney bean |
Fabaceae | Phaseolus L. | bean |
Distribution

Ecdytolopha fabivora is widely distributed in Central and South America.
