[Parasitoids recorded from whiteflies (Homoptera: Aleyrodidae) collected in Venezuela during 1991-2000]
Entomotropica 18 (3), 183-191
Abstract: While recognizing whiteflies (Homoptera: Aleyrodidae) on different host plants from Venezuela, we observed nymphs parasitized by several insect parasitoids. These were isolated in microvials until adult emergence, later transferred and mounted in Hoyer medium, identified and preserved in glass-slides. Voucher specimens are deposited in the Museum of the INIA-CENIAP in Maracay, Aragua State, Venezuela. Hymenopteran parasitoids were found to belong to several genera: Amitus (Platygastridae), Dirphys, Encarsia, Encarsiella, Eretmocerus (Aphelinidae) Entedononecremus (Eulophidae), Signiphora (Signiphoridae), Metaphycus and an unidentified Encyrtidae. Records include: Parasitized whiteflies, host plant, collectors, localities and date of collection.

En el proceso de reconocimiento de moscas blancas (Homoptera: Aleyrodidae), realizado en diferentes plantas de Venezuela, se observaron ninfas con apariencia de estar parasitadas. Estas fueron aisladas en microviales hasta la emergencia de los parasitoides adultos. Luego fueron montados en medio Hoyer, identificados y preservados en láminas. Los insectos fueron depositados en el Museo del INIA-CENIAP en Maracay, Estado Aragua, Venezuela. Se determinaron diferentes Hymenoptera parasitoides pertenecientes a los géneros: Amitus (Platygastridae), Dirphys, Encarsia, Encarsiella, Eretmocerus (Aphelinidae) Entedononecremus (Eulophidae), Signiphora (Signiphoridae), Metaphycus y otro género de Encyrtidae no determinado. Se presentan registros que incluyen: Moscas blancas parasitadas, sus plantas hospederas, colectores , localidades y fechas.
