Thirteen known species of Encyrtidae (Hymenoptera: Chalcidoidea) are recorded, including seven new records from Uttarakhand, India. Rhytidothorax aeriscutellum (Girault) is redescribed along with its morphometrics based on specimens Uttarakhand.

A list of Iranian Encyrtidae (Hymenoptera: Chalcidoidea) is given for the first time. It includes 93 species representing 32 genera. Host information from Iran and distributional data are also provided. Three genera and 7 species are first recorded from Iran. New host records are provided for three species. Two new species, Gyranusoidea iranica sp. n. and Microterys iranicus sp. n., are describ...

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...

Egg parasitoids of the stink bug Edessa meditabunda (F) were studied on rattlepod Crotalaria spectabilis used in soybean crop rotation in Campo Novo do Parecis, Mato Grosso state, central western Brazil. Seven species of parasitoids were found: two Encyrtidae, one Eurytomidae, and four Platygastridae. The occurrence of Trissolcus euchisti (Ashmead) and Trissolcus elimatus Johnson (Platygastrida...

Cerchysiella mesosae Yang sp. nov. (Hymenoptera: Chalcidoidea: Encyrtidae), is described from China. It is a gregarious koinobiont endoparasitoid in mature larvae of Mesosa myops (Dalman) (Coleoptera: Cerambycidae), a wood boring pest of many broad-leaved tree species in China, particularly Quercus mongolica and Q. liaotungensis (Fagaceae) in forest areas of northeastern China. The new species ...

Coronado A. 2006. Ixodiphagus hookeri Howard, 1907 (Hymenoptera: Encyrtidae) in the brown dog tick Rhipicephalus sanguineus Latreille, 1806 (Acari: Ixodidae) in Venezuela. Entomotropica 21(1):61-64. Nymphs of the ixodid tick Rhipicephalus sanguineus were found naturally infected by the tiny wasp Ixodiphagus hookeri. The parasitism resulted in the death of the host ticks, as cause of ingestion o...

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....
