Biology and Ecology:

Auanema melissense is a species of entomopathogenic nematodes that appears to have a symbiotic association with bacteria of the family Enterbactericeae (Manjula et al., 2020).

Life Cycle:

Auanema melissense reproduces by a rather unique form of parthenogenesis known as auto-pseaudogamy. In pseudogamy, the presence of  male sperm is necessary to activate development of oocytes but DNA is not transferred.  In most cases of pseudogamy, the sperm is obtained by copulation with other species. In auto-pseudogamy, females produce a small number of male offspring to satisfy their need for sperm (Launay et al., 2020).
