BAUDINO, E.M et al. Parasitoides del bicho canasto, Oiketicus platensis (Lepidoptera: Psychidae) en el caldenal pampeano. RIA. Rev. investig. agropecu. [online]. 2017, vol.43, n.3, pp.291-296. ISSN 1669-2314.

An important growth in the populations of Oiketicus platensis Berg is being observed since 2006 in native forests of Prosopis caldenia in La Pampa province. The aims of the present work are: 1) to survey bagworm moth larval parasitoids, and 2) to determine which species are most abundant in the study area. The study was carried out at three sites of La Pampa province located in the Espinal biogeographical province. Larvae were collected from November 2012 to March 2013. Seventeen parasitoid species were obtained. Fifteen species of parasitic wasps were identified belonging to the families Eulophidae, Encyrtidae, Eurytomidae, Eupelmidae, Torymidae, Chalcididae, Ichneumonidae, Braconidae and Bethylidae. Additionally, two parasitoid fly species were identified belonging to the family Tachinidae. Parasitoids appear one month after the birth of the larvae. Larval parasitism reached 17,6%, with a clear dominance of dipteran parasitoids (81,6%).
