Diachasmimorpha longicaudata (Ashmead, 1905)

(Figure 1C)

Diagnosis. Occipital carina well-developed laterally, notauli deeply impressed and smooth, propodeum varying from extensively rugose to smooth with only trace of weak carinae, second metasomal tergum striate medially, fore wing m-cu arising from a shortened 2 nd submarginal cell 5-sided, hind wing m-cu present.

Comments. This parasitoid can be separated from other species discussed here by the fore wing m-cu arising from a shortened 2 nd submarginal cell 5-sided. It is originally from the Indo-Australian Region. Diachasmimorpha longicaudata has been used in several biological control programs in Latin America (Ovruski et al. 2000), because it adapts readily to several pest fruit flies. In Brazil, it was introduced in 1994 by “Embrapa Mandioca e Fruticultura” (Carvalho et al. 1995) and is present in 10 states. Some studies on D. longicaudata, such as the olfactory response (Silva et al. 2007), field dispersal, rates of parasitism and field survival when reared in two hosts (Camargos et al., 2016, 2018), and learning behavior of the female related to two essential oils (Zadra et al. 2018) have been conducted in Brazil. D. longicaudata has recently been certified as a biological insecticide in Brazil, as it was published in the Federal Register, on September 3, 2018, edition 170, section 1, p. 127, based on Joint Normative Instruction nr. 2 on August 8, 2018.
