T he largest superfamily among parasitoid Hymenoptera is Ichneumonoidea that occurs in all habitats, being easily collected. Its hosts are mainly larvae and pupae of holometabolous insects, excluding Megaloptera and Siphonaptera, occurring rarely on individual eggs and are subdivided into Ichneumonidae and Braconidae. Many Braconidae parasitis hemimetabola nymphs (Homoptera, Heteroptera, Isoptera and Psocoptera) and some adult parasites of Coleoptera and Hymenoptera. Some species may be phytophages (Matthews, 1984; Wahl & Sharkey in Goulet & Huber, 1993). Askew & Shaw (1986) distinguished the Ichneumonoidea in idiobionts, those who permanently paralyze the host and in koinobionts, those who temporarily paralyze, allowing the development of the post-posture host. Ichneumonoidea are among the most diverse neotropical superfamilies with more than 40,000 described species distributed in 694 genera and together with Chalcidoidea correspond to 48% of all neotropical Hymenoptera (Grissell & Schauff, 1990). Among the Braconidae, the Subfamily Alysiinae is cosmopolitan with more than 1000 species described worldwide; of the 41 genera of the New World, 20 occur in the Neotropical region (Wharton et al. 1997). Alysiinae are koinobion andt endoparatoids of brachicerous dipterans; Alysiini are Qeios ID: 249386 · https://doi.org/10.32388/249386 1/14 Qeios, CC-BY 4.0 · Article, November 23, 2019 associated with more than 20 Families of Diptera (Wharton, 1984). Many of its hosts occur associated with manure, fungi or decaying plant and animal matter; few parasites T ephritidae larvae. Pupation of the parasitoid occurs within the host's pupary.Most are solitary parasitoid; some species of Aphaereta sp. are gregarious. T he main function of exodont jaws seems to be to allow the adult to break the host's pupary to leave him (Griffiths, 1964). T hese jaws could also serve to break the substrate where the host's pupary is located. Some of the best studied Alysiinae are the paleatic species Alysia manducator and the nearctic species Aphaereta pallipes. T he Alysiinae of the genera Gnathopleura Wharton, Aphaereta and Alysia Latreille have been created and used for biological control of caliphorids and muscids, but without much success (Legner, 1978; Wharton, 1984). In Brazil, studies on Parasiinae alysides of muscoid dipterans refer mainly to species of the genera Aphaereta and Gnathopleura. Aphaereta sp. was one of the predominant parasitoids on muscoid dipterans collected on various substrates in the states of Goiás and Minas Gerais (Marchiori et al., 2002; Marchiori & Silva Filho, 2004; Silva, 2007). Gnathopleura quadridentate, Wharton 1986 was recorded in several studies conducted in Brazil, associated with species of Oxysarcodexia, Sarcodexia and Peckia (Diptera, Sarcophagidae) on various substrates, occurring in areas of mesophilic forest and urban environments (Marchiori et al. , 2004; Marchiori & Silva Filho, 2004; 2006; Bonani et al., 2006; Marchiori, 2007). Chalcididae are usually endoparasitoid, primary and solitary mainly of mature Diptera larvae (including aquatic as in Stratiomyidae) and Lepidoptera pupae (Grissell & Schauff, 1997; T avares, 2007), but are also registered as Coleoptera parasitoids (including the supposed primitive hosts whose larvae develop in wood), Neuroptera, Hymenoptera, Strepsiptera and as hyperparasitoids (Naumann, 1991). T here are also gregarious and ectoparasitoid species (Noyes, 2003). Species of the genus Brachymeria Westood are important primary parasitoids of couscoid dipterans, such as those of the family Sarcophagidae (Burks, 1960; Habu, 1960; Grissel & Schauff, 1990; Marchiori, 2001) and Calliphoridae (Bishop et al., 1996). Some species are of economic importance because they attack insect pests and others Qeios ID: 249386 · https://doi.org/10.32388/249386 2/14 Qeios, CC-BY 4.0 · Article, November 23, 2019 of forensic importance (Gauld & Bolton, 1988; Santana et al.2008). T he species Brachymeria podagrica (Fabricus) was found parasitising the following species of dipterans of forensic importance: Chrysomya sp., Chrysomya albiceps (Wiedemann), Chrysomya megacephala (Fabriicus) (Calliphoridae), Hemilucilia flavifacies (Calliphoridae) Erderlein, Ophyra aenescens (Wiedemann) (Muscidae), Oxysarcodexia thornax (Walker) (Sarcophagidae), Peckia chrysostoma (Wiedemann) (Sarcophagidae), Peckia intermutnas (Walker) (Diptera: Sarcophagidae), Sarcodexia lambens (Wiedemann) and Squamatoids trivittatus (Curran, 1927) (Diptera: Sarcohagidae) (Silva, 1999; Marchiori et al., 2001a; Marchiori et al., 2002a; Marchiori et al., 2003a; b; c; Silva et al., 2005). Granato & Oliveira Costa (2008) collected from immature specimens of dipterans of forensic importance Brachymeria sp. and Conura sp. T he family Diapriidae (Hymenoptera: Proctotrupoidea) has many common species, little is known about the biology of these parasitoids. Oviposition can occur in the host larva or pupa. Most Diapriidae are parasitoids of Calliphoridae, Muscidae, Sarcophagidae, Sphaercoeridae and T achinidae (Silva, 1991). Species of the genus T richopria are usually of immature stages of Diptera (Legner et al., 1976). T richopria sp. is cited in the literature as parasitoid of some Sarcophagidae, Sepsidae, Muscidae and Calliphoridae (Figg et al., 1983; Blume, 1984; Silva, 1991). T richopria sp. was found parasitizing the following species of dipterans of forensic importance: C. albiceps, Chrysomya putoria (Wiedemann), Fannia canicularis (L.), H. flavifacies, Ophyra sp., Palaeosepsis spp., Phaenicia eximia (Wiedemann), P. chrysosotma , P. intermutnas, P. eximia and Synthesiomyia nudiseta (Wulp) (Muscidae) (Silva, 1991; Monteiro & Prado, 2000; Marchiori et al., 2000a; Marchiori et al., 2001; Bonani et al., 2004; Marchiori et al., 2002; Marchiori et al., 2004) T he Family Encyrtidae and a general form are endoparasitoids of eggs, immature and adults or egg predators mainly of cochineals (Hemiptera: Coccidae and Pseudococcidae), although several hosts have already been registered in several groups of Arthropoda (T achikawa, 1981), as well as hyperparasitoids and polyembryonic parasitoids (Noyes, 1995). Most egg and pupe parasitoids have idiobiont strategy, while larval parasitoids have koinobiont strategy. Several particularities are noted in the biology of Encyrtidae.

T he species T achinaephagus zealandicus Ashmead was found parasitating the following species of dipterans of forensic importance: C. megacephala, C. putoria, Musca domestica (L.) (Muscidae) and S. lambens (Monteiro, 1995; Sereno & Neves, 2003; Costa et al., 2004; Morretti & Ribeiro, 2006) and the species Hemencrytus herbertii parasitoids the species: C. albiceps, Euboettcheria colusor (Curran et Walley) (Sarcophagidae), Hemilucilia flavifacies (Calliphoridae), M. domestica, Ophrya sp., O. thornax, P. eximia, P. chrysosotma, P. intermutnas and S. nudiseta (Silva, 1991; Noyes & Wodley, 1994; Marchiori et al., 2003b; d; Marchiori et al., 2004). T he Eulophidae family, as you would expect in such a large group, various habits of life occur as parasitoids of eggs, larvae and pupae of more than 10 orders of insects can be solitary, gregarious, idiobionts, koinobionts, ectoparasitoids and endoparastoids, including aquatic, predators of Arachnida oothetes and even Nematoda (LaSalle & Suffcha, 1995). However, there is a pattern among hosts, predominantly those whose immature larvae are housed in gallhouses, mines or stems, especially of Lepidoptera, Coleoptera, Diptera and Hymenoptera orders. T achinobia species behave like gregarious parasitoids of Lepidoptera and Diptera pupae (Boucek, 1977; La Salle, 1994). T achinobia spp. parasitised the following species of dipterans of forensic importance: C. albiceps, P. eximia, Megaselia scalaris (Loew) (Phoridae) O. aenescens, O. thornax, parasitou C. albiceps, P. eximia, Oxysarcodexia sp. and P. intermutnas and S. nudiseta (Silva, 1991; Marchiori et al., 2005a; Marchiori et al., 2006a). T he Eurytomide family are mostly parasitoids of usually endophytic immature insects tenants or phytophages. T enants can feed on the galley material and also from the gallant. Phytophages can be galleys, blowers or feed on seeds from a wide variety of plants. T here are several types of idiobiont parasitoids, koinobionts, solitary or gregarious, kleptoparasitoids, facultative hyperparasitoids or not (Noyes, 2003) and these occur in several orders, such as Diptera, Coleoptera, Hymenoptera, Lepidoptera, Heteroptera eggs and Orthoptera. Eurytoma sp. parasitized the following species of dipterans of forensic importance: Qeios ID: 249386 · https://doi.org/10.32388/249386 4/14 Qeios, CC-BY 4.0 · Article, November 23, 2019 Fannia pusio (Wiedemann) (Fanniidae) (Marchiori, 2007a) and M. domestica (Bruno et al., 1992;
