Pediobius thysanopterus

Pediobius thysanopterus Burks

Systematic position: Insecta, Holometabola, Hymenoptera, Apocrita, Chalcidoidea, Eulophidae.

Distribution: Middle East, Egypt and Israel.

Morphology: Adults are 0.7-1.0 mm in length, body shiny black, wings with only a single, anterior vein.

Life history: Pediobius thysanopterus is an Endoparasitoid of Gynaikothrips ficorum. It is most active in autumn, its numbers decreasing in summer. This decrease may be due to predation by Montandoniola moraguesi, which feeds on the parasitized host larvae.

Economic importance: In Israel P. thysanopterus may attack almost 90% of the host’s larvae.
