Paracrias

Ashmead, 1904

Paracrias is a of in the Eulophidae, occurring exclusively in the New World with greatest diversity in the tropics. Larvae are gregarious parasitoids of stages of beetles, primarily within Curculionoidea. records include weevils (Curculionidae), leaf-rolling weevils (Attelabidae), and bruchine seed beetles (Chrysomelidae). The genus has been studied for its potential as a agent of seed and bud pests.

Habitat

Associated with seeds, buds, and syconia of plants; specifically documented from seeds of Melanoxylon brauna and syconia of fig trees (Ficus spp.). Laboratory rearing has occurred under uncontrolled temperature, humidity, and conditions.

Distribution

New World distribution with records from Rica, Brazil (Minas Gerais State), and the eastern United States (Maryland). Greatest diversity occurs in tropical regions.

Host Associations

Life Cycle

Larvae are gregarious that develop on stages of beetles. emerge from infested seeds or other host substrates.

Behavior

present: males have all flagellomeres distinctly separated, longer petiole, and brighter body color compared to females. Females have prepectus entirely reticulated and less bright body color.

Ecological Role

of larvae that damage seeds, buds, and plant reproductive structures; potential agent for seed pests and fig crop pests.

Human Relevance

Investigated for applications against bruchine seed beetles and other weevil pests. Association with native tree (Melanoxylon brauna) and crop plants (figs) suggests potential for managed and natural pest suppression.
