Steinernema scapterisci

Definition

A species of entomopathogenic nematode in the family Steinernematidae, native to southern South America and introduced to Florida as a biological control agent against pest mole crickets (Neoscapteriscus spp.). The species infects orthopteran hosts through soil-borne infective juveniles that penetrate the host cuticle and release symbiotic bacteria (Xenorhabdus spp.) to kill the insect within 24–48 hours.

Etymology

Genus Steinernema honors German nematologist Gotthold Steiner; specific epithet scapterisci refers to the mole cricket host genus Scapteriscus.

Example

Steinernema scapterisci is applied to turfgrass as a biocontrol treatment for tawny mole cricket (Neoscapteriscus vicinus) infestations, where the nematode seeks out subterranean hosts and establishes lethal infections.

Synonyms

• mole cricket nematode

Usage Notes

Distinguished from Steinernema feltiae and S. carpocapsae by host specificity; S. scapterisci is adapted to warm climates and orthopteran hosts rather than lepidopteran or coleopteran targets. The species is commercially formulated for mole cricket management in turf and pasture systems.
