Diadegma mollipla (Holmgren) 

(Life: Kingdom: Metazoa (animals); Phylum: Arthropoda; Class: Hexapoda; Order: Hymenoptera;  Superfamily: Ichneumonoidea; Family: Ichneumonidae; Subfamily: Campopleginae; Genus: Diadegma)

Limneria mollipla Holmgren, 1868. Holotype: in Naturhistoriska Riksmuseet, Stockholm. Type locality:



Canary Islands, Mauritius, Reunion, South Africa, Yemen, Zambia, Zimbabwe.


Solitary larvo-pupal enparasitoid of Plutella xylostella (L.) (Lepidoptera: Plutellidae) and Phthorimaea operculella (Lepidoptera: Gelechioidea).  Diadegma mollipla is a well known parasitoid of the diamondback moth (P. xylostella) and the potato tuber moth (P. operculella). Surprisingly, its host range appears to be restricted to these two unrelated species. The determination of Diadegma species is difficult as D. mollipla is morphologically variable (areolet more or less closed, for example) and numerous sibling Diadegma species develop also on P. xylostella (Azidah et al. 2000; Rousse & Villemant, 2012).
