Habitat
Pecan orchards (Carya illinoiensis) have been documented as where at least one was reared from nests. The is associated with environments where lepidopteran hosts occur.
Distribution
Mexico (where multiple are common and well-documented); Nearctic region including the United States (Vermont confirmed); Rica (where specimens were previously misidentified).
Host Associations
- Hyphantria cunea - Reared from web nests on pecan; D. hyphantriae specifically associated
- Heterocampa manteo - D. bethunei documented to parasitize this
- Carya illinoiensis - plant of lepidopteran hostPecan trees where H. cunea nests were collected
Behavior
Diradops bethunei has been observed to reduce larval capsule size in its Heterocampa manteo, indicating a morphological impact on host development.
Ecological Role
agent of lepidopteran pests, particularly the fall webworm (Hyphantria cunea) in pecan orchards.
Human Relevance
Potential biocontrol agent for agricultural pests; D. hyphantriae has been noted as very common in Mexican pecan-growing regions.
