Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) parasitóide de dípteros muscóides coletado em Itumbiara, Goiás

Abstract

This work reports the occurrence of parasitoid Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) parasitizing pupae of flies (Diptera) in different substrata in Itumbiara, Goiás. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of flies or their parasitoids. From May 1998 through April 2002, 737 parasitoids were collected in human feces, cattle liver, chicken, fish and cattle kidney. The prevalence of parasitism was 67.8%.

Variation in parasitoidism of Protocalliphora azurea (Diptera: Calliphoridae) by Nasonia vitripennis (Hymenoptera: Pteromalidae) in Spain

“…Nasonia species have been widely used as model organisms (Cook et al 2018;Godfray 2010;Lynch et al 2006;Niehuis et al 2010;Oliveira et al 2008), but little is known on its ecology and prevalence of parasitoidism in its natural habitats. Most studies on the relative abundance, prevalence, and intensity of parasitoidism of this wasp have been conducted in urban areas or poultry and cattle farms, where the insect's prevalence is very low (less than 5%) (Marchiori 2004;Marchiori et al 2007;Oliva 2008;Rodrigues-Guimarães et al 2006;Jespersen 1999, 2000), perhaps because all hosts parasitized by the wasp in the aforementioned studies were flies that develop on decaying matter or parasitize cattle. By contrast, birds' nests may be the primary habitat for N. vitripennis, which shows high intensity of parasitoidism when parasitizing Protocalliphora (Peters 2010).…”
