Goniozus omanensis is an ectoparasitoid wasp from the Bethylidae family. [1] G. omanensis can be found in Iraq and Oman and is the most prevalent parasitoid of the lesser date moth which causes significant economic losses. [2] Due to this it has been researched as a method of biological pest control however it has not been proven effective. [3]

Description

The length of Goniozus omanensis ranges from 1.73-2.83mm. It has a very dark brown body with paler lower legs and antennae. Females can be distinguished from males due to their pointed distal metasoma and ovipositor. [2]

After mating female G. omanensis attack and paralyze their prey, they lay their eggs on the skin of the host larvae. When the eggs hatch they then spend 3-4 days feeding on the larvae before spinning a white silky cocoon nearby. After 7-9 days of pupation they emerge from the cocoon and begin to seek out a mate. The lifespan of females is approximately three times longer than males and typically more females hatch than males. The behavior of host guarding has also been observed where females that have paralyzed a host will guard it aggressively from other females. [2]
