Indigenous natural enemies attacking Tuta absoluta (Lepidoptera: Gelechiidae) in Southern France.

摘要: The South American tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a serious worldwide threat to industry. Since it has spread the Afro-Eurasia, was responsible of extensive damage and its control mainly relied on chemical insecticide applications. In this context, survey natural enemies attacking T. spontaneously conducted in Southern France. Infested leaves were collected from protected crops seasons 2011 2012. Three species mirid predators [Macrolophus pygmaeus (Rambur), Nesidiocoris tenuis (Reuter) Dicyphus sp.] found preying eggs young larvae moth both sampling. Eggs also attacked by two trichogrammatid species, Trichogramma achaeae Nagaraja & Nagarkatti sp. Whereas, parasitized four parasitoid belong families; Braconidae (Bracon nigricans Szepligeti), Eulophidae [Neochrysocharis formosa (Westwood), Stenomesius near japonicus Necremnus artynes]. Although further studies are needed assess actual role these control, obtained results represent first step towards developing biological integrated management strategies against pest Furthermore, stress need conservation indigenous exotic species.
