Chromadorea Tylenchida Aphelenchina Aphelenchoidea Aphelenchoididae Aphelenchoidinae
Martininema Davies, Ye, Kanzaki, Bartholomaeus, Zeng, & Giblin-Davis, 2015
Type species of the genus: Martininema guangzhouensis Zeng, Giblin-Davis & Ye, 2007
The genus was named in honor of Dr. George C. Martin who conducted foundational studeies on the nematodes of fig sycones in Zimbabwe.
Synonyms:
Schistonchus is characterised by having the excretory pore opening in the region of, or posterior to, the metacorpus; Ficophagus by having the excretory pore opening very near the cephalic region; and Martininema by having it opening at the anterior end of the metacorpus. Several species of Schistonchus have a labial disc but there is no evidence of a labial disc in either Ficophagus or Martininema (Davies et al., 2015)..
The genus Martininema is named in honor of George C. Martin who did pioneering work on the nematodes of fig syconia in Zimbabwe in the Deoartment of Nematology of the Ministry of Agriculture..
Frequently found associated with sycones (enclosed infrutescences) of Ficus spp. Probably transported by fig wasps.
Fig sycones provide an excellent habitat for nematodes. Nematodes of the genera Schistonchus, Ficopgaus and Martininema have phoretic associations pollinating fig wasps (agaonid wasps).
The nematodes feed on fig epidermal cells, mature and lay eggs which develop into males and females. These produce a new generation of entomophilic females which mate, and penetrate the new generation of female wasps. Thus when the wasps emerge, ready to seek fresh sycones, they carry fertilised entomophilic nematodes in their haemolymph.

The nematodes feeding on fig epidermal cells, mature and lay eggs which develop into males and females. These adults produce a new generation of entomophilic females which mate, and penetrate the new generation of female wasps. Thus when the wasps emerge, ready to seek fresh sycones, they carry fertilised entomophilic nematodes in their haemolymph. The pre-reproductive female nematode, which is the dispersal stage of Schistonchus and related genera, uses volatiles and cuticular hydrocarbons from the female pollinating wasps to select the appropriate wasp vector (Davies et al. 2015).
