First records of Charipinae (Hymenoptera, Cynipoidea, Figitidae) aphid hyperparasitoids from Malta

Charipinae material has been collected from different localities in Malta. Three species have been identified: Alloxysta citripes , Alloxysta pilipennis and Phaenoglyphis villosa in association with two aphids and one parasitoid species. Diagnosis and information about distribution and hosts of each species is given. Plates with diagnostic features of these three species are also included. These findings represent the first record of the subfamily Charipinae in Malt

First record and new hosts relationships of Alloxysta brevis (Thomson, 1862) (Hymenoptera: Cynipoidea: Figitidae: Charipinae) from Algeria

En el marc d'un estudi sobre àfids de cítrics al nord-oest d'Algèria, vam determinar els parasitoides primaris i secundaris sobre les principals espècies d'àfids (Aphis spiraecola Patch, 1914 i Aphis gossypii Glover, 1877) durant el primer període de la primavera de 2015 a Citrus sinensis var. Thomson. Entre els hiperparasitoides associats a A. spiraecola, vam registrar l'espècie Alloxysta brevis (Thomson, 1862) per primera vegada a Algèria. En els estudis realitzats en altres regions algerianes no s'ha detectat la seva presència

Review of the Hartig type collection of Alloxysta (Hymenoptera: Figitidae: Charipinae) and other Alloxysta material deposited in the Zoologische Staatssammlung Museum (Munich)

Hartig's collection of Alloxysta species, deposited in the Zoologische Staatssammlung Museum (ZSM, Munich, Germany), is here reviewed. In total, 19 species and 144 specimens have been studied. Fourteen species, of the previous twenty-two, are now valid: Alloxysta aperta (Hartig, 1841), A. brachyptera (Hartig, 1840), A. castanea (Hartig, 1841), A. circumscripta (Hartig, 1841), A. fuscicornis (Hartig, 1841), A. leunisii (Hartig, 1841), A. longipennis (Hartig, 1841), A. macrophadna (Hartig, 1841), A. melanogaster (Hartig, 1840), A. obscurata (Hartig, 1840), A. pilipennis (Hartig, 1840), A. postica (Hartig, 1841), A. minuta (Hartig, 1840) and A. rufiventris (Hartig, 1840). These species are redescribed and their morphological features are illustrated in corresponding plates. Alloxysta cursor (Hartig, 1840) and A. erythrothorax (Hartig, 1840) are considered as 'nomen dubium'. Two new synonyms are here established among Hartig's species: Alloxysta defecta (Hartig, 1841) with A. castanea (Hartig, 1841) and A. flavicornis (Hartig, 1841) with A. pilipennis (Hartig, 1840). Additional material of Alloxysta deposited in this museum has been examined and new host records are here reported

Species composition and richness of aphid parasitoid wasps in cotton fields in northern China

The cotton aphid, Aphis gossypii (Hemiptera: Aphididae), is a serious pest of cotton across the globe, particularly in the cotton agroecosystems of northern China. Parasitic wasps are deemed to be important natural enemies of A. gossypii, but limited information exists about their species composition, richness and seasonal dynamics in northern China. In this study, we combine sampling over a broad geographical area with intensive field trials over the course of three cropping seasons to describe parasitoid-hyperparasitoid communities in cotton crops. We delineate a speciose complex of primary parasitoids and hyperparasitoids associated with A. gossypii. Over 90% of the primary parasitoids were Binodoxys communis. Syrphophagus sp. and Pachyneuron aphidis made up most of the hyperparasitoids. Parasitism rates changed in a similar way following the fluctuation of the aphid population. Early in the growing period, there were more hyperparasitoids, while later, the primary parasitoids provided control of A. gossypii. The first systematic report of this cotton aphid parasitoid complex and their population dynamics in association with their hosts presented a comprehensive assessment of cotton parasitoid species and provided important information for the establishment and promotion of their biological control of cotton aphids

Species composition and seasonal dynamics of aphid parasitoids and hyperparasitoids in wheat fields in northern China

Parasitoids are important natural enemies of aphids in wheat fields of northern China, and interest in them has increased in recent years. However, little is known regarding parasitoids of wheat aphids, which has hindered the study and understanding of aphid-parasitoid interactions. In the present study, three primary parasitoids and 15 hyperparasitoids were collected in wheat fields during a 2-year survey in northern China (2014, 2015) and a 2-year investigation at Langfang, Hebei Province (2015, 2016). Among them, Aphidius uzbekistanicus Luzhetski was found most frequently among the primary parasitoids, while Pachyneuron aphidis (Bouché) dominated the hyperparasitoid community. Investigation of the dynamics of wheat aphids and parasitoids revealed that the primary parasitoids appeared early in the growing period and that the hyperparasitoids appeared later. Analysis of the seasonal dynamics revealed that growth of the parasitoid population followed that of the aphid population and that the parasitism rates were highest in the late growing period
