Economic Importance:

Most species of Ektaphelenchus species have been described from pine trees (Ruhm, 1956; Massey, 1974) and associated with insect hosts (Hunt, 1993). Little is known of theirl biology and mode of interaction with insect vectors or other nematode species (Gu et al., 2013). Both E. taiwanensis and E. koreanus  have been reported to feed on Aphelenchoides sp. (Gu et al.,2013; Gu et al., 2019).

The potential predatory role of Ektaphelenchus spp. on insects and other nematodes requires further research.

Many species are predators of insects although E. taiwanensis was observed to feed on nematodes (Aphelenchoides sp.).

The insect predators form cocoon-like structures under the elytra of insects or on the hind wings.  They are assumed to feed by penetrating the isect with their stylets (Gu et al., 2013).
