Se estudió el efecto del tipo de manejo cultivo sobre parasitismo Aleurothrixus floccosus (Hemiptera: Aleyrodidae). Los parasitoides estudiados fueron: Cales noacki (Hymenoptera: Aphelinidae), Eretmocerus paulistus Amitus spiniferus Platygastridae) y hiperparasitoide Signiphora sp.(Hymenoptera: Signiphoridae). El estudio se realizó en Oasis Pica, ubicado Desierto Atacama, Región Tarapacá, Chile...

Previously, analysis of 16S rDNA sequences placed a newly discovered lineage of bacterial symbionts of arthropods in the 'Bacteroidetes'. This symbiont lineage is associated with a number of diverse host reproductive manipulations, including induction of parthenogenesis in several Encarsia parasitoid wasps (Hymenoptera: Aphelinidae). In this study, electron microscopy and phylogenetic analysis ...

A mixed species release of parasitoids is used to suppress outbreaks of tobacco whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae); however, this biocontrol may be inhibited by interspecific interactions. We investigated the effects of mixed releases of natural enemies of B. tabaci on predation rates, parasite performance and adult parasitoid emergence under greenhouse conditions. We tested the ...

Chalcidoidea (Hymenoptera) are extremely diverse with more than 23,000 species described and over 500,000 species estimated to exist. This is the first comprehensive phylogenetic analysis of the superfamily based on a molecular analysis of 18S and 28S ribosomal gene regions for 19 families, 72 subfamilies, 343 genera and 649 species. The 56 outgroups are comprised of Ceraphronoidea and most pro...
