Diversity of Ophioniformes wasps (Hymenoptera: Ichneumonidae) in a Central-West Brazilian Savanna area

This study aimed to assess the diversity, abundance and seasonal dynamics of Ophioniformes wasps collected throughout a year, as recorded in Malaise traps set at the Reserva Ecológica da Universidade Estadual do Mato Grosso do Sul, a Brazilian Savanna area in Aquidauana city, MS. A total of 621 specimens of Ophioniformes belonging to 11 subfamilies, 30 genera and 106 species were sampled. Despite the impressive number of species found, in a pattern of a few relatively abundant species and many rare ones, our data estimate even higher richness, probably between 125 to 165 species in the studied area. The genera Diadegma, Nonnus, Diradops, Meniscomorpha, Syzeuctus, Ophiopterus and Thyreodon are recorded for the first time in Mato Grosso do Sul State. Among the climatic variables evaluated, mean temperature and relative humidity were positively and significantly correlated with richness and abundance. Our data highlights the huge unknown species richness of these parasitoids in Brazil and the need of taxonomic studies efforts in the future

Estudo dos Campopleginae (Hymenoptera, Ichneumonidae) neotropicais com ênfase na fauna da Mata Atlântica, Brasil.

The material used in this study comes from the projects: "Biodiversidade de Isoptera e Hymenoptera" (BIOTA/FAPESP), "Diversidade da fauna de Braconidae (Hymenoptera) em diferentes altitudes em Campos do Jordão, São Paulo, Brasil (CNPq) and from brazilian collections. This work has for main objectives a survey of the Campopleginae fauna in Brazil and to know its distribution throughout latitudinal and altitudinal gradients in areas of Atlantic Forest. Using Malaise traps, Moericke traps and sweeping the vegetation were obtained a total of 7.550 specimens identified and distributed in 19 genera. The genus Enytus was for the first time cited to Brazil and a new genus was identified. Microcharops, Casinaria, Dusona and Nonnus were the most common genera. Studying the Campopleginae throughout a latitudinal gradient, in eighteen localities of Atlantic Forest, the higher values of abundance, species richness and diversity were recorded in the Brazilians regions South and Southeast. The results indicated the reduction of the abundance, diversity and species richness of this subfamily in direction the localities of lower latitudes. In the analysis of the diversity of the fauna of the Campopleginae throughout an altitudinal gradient in other area of Atlantic Forest (Campos do Jordão, SP), the higher number of specimens was evidenced in mid altitudes. The diversity and the species richness showed a strong influence of the climate. The results of this study extend the knowledge on the distribution of the Campopleginae in Neotropical region and contribute for studies on distribution of parasitoid insects throughout latitudinal and altitudinal gradients.Universidade Federal de Minas GeraisO material utilizado neste estudo provém de coletas realizadas pelos projetos: Biodiversidade de Isoptera e Hymenoptera (BIOTA/FAPESP), Diversidade da fauna de Braconidae (Hymenoptera) em diferentes altitudes em Campos do Jordão, São Paulo, Brasil (CNPq) e de coleções brasileiras. Este trabalho teve por objetivos principais realizar um levantamento da fauna dos Campopleginae no Brasil e conhecer sua distribuição ao longo de gradientes latitudinal e altitudinal em áreas de Mata Atlântica. Através de armadilhas de Malaise, armadilhas de Moericke e varredura da vegetação foram obtidos 7.550 exemplares identificados e distribuídos em 19 gêneros. O gênero Enytus foi pela primeira vez citado para o Brasil e um novo gênero foi identificado. Microcharops, Casinaria, Dusona e Nonnus foram os gêneros mais abundantes. Estudando os Campopleginae ao longo de um gradiente latitudinal, em dezoito localidades de Mata Atlântica, os maiores valores de abundância, riqueza e diversidade foram obtidos nas regiões sul e sudeste. Os resultados indicaram a diminuição da abundância, diversidade e riqueza desta subfamília em direção a localidades de menores latitudes. Na análise da diversidade da fauna dos Campopleginae ao longo de um gradiente altitudinal em outra área de Mata Atlântica (Campos do Jordão, SP), o maior número de indivíduos foi constatado em altitudes intermediárias. A diversidade e a riqueza se mostraram fortemente influenciadas pelo clima. Os resultados obtidos neste estudo ampliam o conhecimento sobre a distribuição dos Campopleginae em regiões Neotropicais e contribuem para estudos sobre distribuição de insetos parasitóides ao longo de gradientes latitudinal e altitudinal

Estudo da fauna de Hymenoptera parasitóides associados a hortas orgânicas e da utilização de extratos vegetais no controle de Plutella xylostella (Lepidoptera, Plutellidae)

This work aimed to study the Hymenoptera parasitoids fauna in organic crops areas and the insecticidal activity of plant extracts from Allamanda cathartica (Apocynaceae) and Coriandrum sativum (Apiaceae) and the latex of Euphorbia milii (Euphorbiaceae) on Plutella xylostella (Lepidoptera, Plutellidae). During March 2006 to February 2007 twelve samples were performed using Malaise traps in each of the three studied organic crop areas. Immature Lepidoptera were also collected to verify the emergence of parasitoids. A total of 46,231 specimens, identified in 28 families were collected by Malaise trap. The most representative were Braconidae and Ichneumonidae (Ichneumonoidea), Eulophidae, Mymaridae and Pteromalidae (Chalcidoidea), Scelionidae (Platygastroidea) and Figitidae (Cynipoidea). Twenty-two subfamilies of Braconidae were identified, Microgastrinae being the most abundant in the three locations sampled. Seventeen subfamilies of Ichneumonidae were recognized and, in the three farms, the Campopleginae and Cremastinae were the most abundant. The genera Lysiphlebus, Opius, Dolichozele and Aleiodes were the most abundant of the 81 Braconidae genus identified. The results showed that the practice organic farming has positive effects on the abundance, richness and diversity Hymenoptera parasitoids fauna, but the results varied according to taxonomic level used and the type of management performed. The Braconidae and Ichneumonidae (Ichneumonoidea), Eulophidae and Encyrtidae (Chalcidoidea) were the most important parasitoids reared from the immature Lepidoptera hosts. New information on the associations between hosts and parasitoids were obtained for Hypomicrogaster (Braconidae, Microgastrinae) parasitizing larvae of Hellula phidilealis (Lepidoptera, Pyralidae), Eiphosoma (Cremastinae, Ichneumonidae) parasitizing larvae of Diaphania hyalinata (Pyralidae, Lepidoptera) and Colpotrochia (Ichneumonidae, Metopiinae) parasitizing larvae of Spodoptera eridania (Lepidoptera, Noctuidae). The tests performed with different concentrations of Allamanda cathartica and Coriandrum sativum extracts and Euphorbia milii latex affected the larval Plutella xylostella mortality.Universidade Federal de Minas GeraisEste trabalho teve por objetivos o estudo da fauna de Hymenoptera parasitóides em hortas orgânicas e da atividade inseticida de extratos vegetais de Allamanda cathartica (Apocynaceae) e Coriandrum sativum (Apiaceae) e do látex de Euphorbia milii (Euphorbiaceae) sobre Plutella xylostella (Lepidoptera, Plutellidae). No período de março de 2006 a fevereiro de 2007 foram realizadas doze amostragens por meio de armadilhas Malaise em cada uma das três hortas orgânicas estudadas. Também foram coletados imaturos de Lepidoptera, mantidos em laboratório para verificar a emergência de parasitóides. Foram coletados 46.231 exemplares de Hymenoptera, identificados em 28 famílias. As mais representativas foram Braconidae e Ichneumonidae (Ichneumonoidea), Eulophidae, Mymaridae e Pteromalidae (Chalcidoidea), Scelionidae (Platygastroidea) e Figitidae (Cynipoidea). Dentre as vinte e duas subfamílias de Braconidae amostradas, Microgastrinae foi a mais abundante nos três locais estudados. Em relação aos Ichneumonidae, dezessete subfamílias foram identificadas e, nas três hortas, Campopleginae e Cremastinae foram as mais abundantes. Foram identificados 81 gêneros de Braconidae, sendo os mais abundantes Lysiphlebus, Opius, Dolichozele e Aleiodes. Os resultados evidenciaram que a prática agrícola orgânica possui efeitos positivos sobre a abundância, riqueza e diversidade da fauna de Hymenoptera parasitóides, porém os resultados variaram de acordo com nível taxonômico utilizado e o tipo de manejo realizado. Dentre os parasitóides emergentes dos lepidópteros coletados, destacaram-se os Braconidae e os Ichneumonidae (Ichneumonoidea), Eulophidae e Encyrtidae (Chalcidoidea). Novas informações sobre as relações entre hospedeiros e parasitóides foram obtidas para Hypomicrogaster (Braconidae, Microgastrinae) parasitando larvas de Hellula phidilealis (Lepidoptera, Pyralidae), Eiphosoma (Cremastinae, Ichneumonidae) parasitando larvas de Diaphania hyalinata (Pyralidae, Lepidoptera) e Colpotrochia (Ichneumonidae, Metopiinae) parasitando larva de Spodoptera eridania (Lepidoptera, Noctuidae). Os testes realizados com diferentes concentrações dos extratos de Allamanda cathartica e Coriandrum sativum e do látex de E. milii afetaram a mortalidade larval de Plutella xylostella

A new species of Cryptophion (Hymenoptera: Ichneumonidae) from southeastern Brazil

ABSTRACT Cryptophion Viereck, 1913 is a small Neotropical genus of Campopleginae, with seven described species, two recorded from Brazil. In this paper, a new species from the Atlantic Forest of southeastern Brazil is described and illustrated. In addition, a key to the Brazilian species is provided. Cryptophion atlanticus sp. nov. (holotype female deposited in DCBU: Brazil, São Paulo, São Luiz do Paraitinga, Parque Estadual da Serra do Mar) is diagnosed by mesoscutum more or less uniformly punctate, except the notaular region with coarser and irregular rugae, scutellum bearing irregular lateral longitudinal rugae; forewing with areolet not distinctly petiolate above and hind tarsal claw pectinate, but with a large space in the middle, and distinctly longer than the arolium
