The Norwegian species of Copidosoma Ratzeburg (Hymenoptera: Chalcidoidea: Encyrtidae).
The species of Copidosoma Ratzeburg (Hymenoptera: Encyrtidae) are reviewed for Norway. Sixteen species are recognized, of which one, Copidosoma longicaudata sp. nov., is newly described, illustrated and compared with closely related species. Seven species represent new distribution records for Norway--C. aithyia (Walker), C. genale (Thomson), C. herbaceum Mercet, C. primulum (Mercet), C. radnen...
متن کاملMale soldier caste larvae are non-aggressive in the polyembryonic wasp Copidosoma floridanum.
Polyembryonic wasps are the only parasitoids in which sociality has evolved. Theory implicates both competition and sex ratio manipulation in the evolution of a sterile soldier caste. However, investment in soldiers by males and females is predicted to differ depending upon how offspring are allocated to hosts and the mating system. Here, we compared male and female soldiers in the polyembryoni...
متن کاملThe metabolic enzyme phosphoglucose isomerase (Pgi) affects the outcome of intra-specific competition in a polyembryonic wasp
1. Polyembryonic parasitoid wasps in the family Encyrtidae (Hymenoptera) have evolved a caste system consisting of morphologically and functionally distinct larvae called soldiers and reproductives. 2. Two selective pressures are thought to underlie the evolution of the soldier caste: defence against competitors and resolution of the sex ratio conflict. Previous studies also indicate that soldi...
متن کاملCardinium in Plagiomerus diaspidis (Hymenoptera: Encyrtidae).
The bacterial symbiont Cardinium (Bacteroidetes) was previously implicated in the thelytokous reproduction of the parasitoid Plagiomerus diaspidis Crawford (Hymenoptera: Encyrtidae). Horizontal transmission of the symbiont among the cactus scale Diaspis echinocacti Bouché (Homoptera: Diaspididae) and its hymenopteran parasitoids has been suggested. In this study, the bacteria associated with D....
متن کاملArthropod Biology Biology of Psyllaphycus diaphorinae (Hymenoptera: Encyrtidae), a Hyperparasitoid of Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae) and Tamarixia radiata (Hymenoptera: Eulophidae)
The biology and ecology of Psyllaphycus diaphorinae Hayat, a potential natural enemy of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), is poorly understood. In April 2013, six P. diaphorinae females collected from Punjab, Pakistan emerged from parasitized Asian citrus psyllid nymphs in quarantine at the University of California, Riverside and were used to initiate co...
