And recorded as a parasitoid of A. fabae in Algeria (Starý et al. 1971), Morocco ( Starý 1962), and Iraq ( Starý 1969; Al-Azawi 1970; Starý & Kaddou 1971) without referring to host plant.

In Egypt, it has been recorded as a parasitoid of the cowpea aphid A. craccivora in faba bean in different areas of Egypt ( El-Defrawi et al. 2000; Ragab et al. 2002; Abdel-Rahman 2005; Abdel-Samad & Ahmed 2009; Ali 2014; Jabbar et al. 2020).
