First Record of the Dacetine Ant Strumigenys argiola (Emery, 1869) (Hymenoptera: Formicidae) from Romania

2016

AbstractThe Romanian ant fauna is poorly known. It seems that many cryptic and parasitic species are missing from the checklist, including species with their ranges primarily outside of the Mediterranean. Herein,Strumigenys argiola(Emery, 1869) is a newly recorded species for the ant fauna of Romania, one male being collected in North–Eastern Romania.Strumigenys argiolalives in the soil, and hunts for small arthropods. For the time being, a total of 112 ant species are known from Romania.

Dinotrema vitobiasi sp. nov., a new Spanish species of the genus Dinotrema Foerster, 1862 (Hymenoptera: Braconidae) with only basomedially sculptured…

2013

A new species of Dinotrema with only basomedially sculptured propodeum, Dinotrema vitobiasi sp. nov., is described from Spain. A comparison of this new species with its three morphologically most similar species, D. vituperatum (Fischer, 1974), D. latifemur (Fischer, 1975) and D. carinatum (Tobias, 1962), is provided.

Application of Toxkit microbiotests for toxicity assessment in soil and compost

2004

The potential of Toxkit microbiotests to detect and analyze pollution in agricultural soil and the quality of compost was studied. The toxicity tests used included seed germination biotests using cress salad (Lepidum sativum L.), tomato (Lycopersicum esculentum L.), and cucumber (Cucumis sativus L.), and the Toxkit microbiotests included those with microalgae (Selenastrum capricornutum), protozoa (Tetrahymena thermophila), crustaceans (Daphnia magna, Thamnocephalus platyurus, and Heterocypris incongruens), and rotifers (Brachionus calyciflorus). Experiments on compost were undertaken in a modified solid-state fermentation system (SSF) and under field conditions (in a windrow). To promote th…

Taxonomic review of the fungal-inhabiting plant bug genera Bothriomiris and Dashymenia (Hemiptera: Heteroptera: Miridae: Cylapinae: Bothriomirini), w…

2016

The two closely related and frequently confused genera of the fungal-inhabiting plant bug subfamily Cylapinae, Bothriomiris Kirkaldy, 1902 and Dashymenia Poppius, 1910 are redefined and reviewed. Two new species of Dashymenia, D. artchawakomi, new species and D. gorczycai, new species, are described from Thailand. Bothriomiris capillosus Yasunaga, 2000 and B. yakushima Yasunaga & Miyamoto, 2012 are transferred to the genus Dashymenia Poppius, and a revised key to the two genera is provided. Color habitus images of the adults are given for Dashymenia artchawakomi, D. capillosa, and D. gorczycai. The male genitalic structures of the following species are illustrated: Bothriomiris ernsti Yasun…

Predatory habits of the grasshopper-hunting waspStizus continuus(Hymenoptera: Crabronidae): diet preference, predator–prey size relationships and for…

2009

In a coastal salt-marsh of Spain, the digger wasp Stizus continuus primarily hunted for grasshoppers of the genus Heteracris, revealing (at least in the period of the study and in this area) this wasp to be almost monophagous. In contrast, grasshoppers of the genus Acrotylus were ignored by the wasps in spite of their high abundance in the environment. We hypothesize that this bias occurred because Acrotylus is found more often on the soil and on grasses, while Heteracris is nearly only found on Sarcocornia bushes, which probably represent the habitat mostly exploited by the wasps for hunting. The greater variance in size of the prey collected by larger females produced weak wasp–prey size …

Presence of very high prevalence and intensity of infection with Fasciola hepatica among Aymara children from the Northern Bolivian Altiplano.

1997

Abstract Coprological studies of school children from four communities in the Northern Bolivian Altiplano were carried out in order to estimate the prevalences and intensities of Fasciola hepatica infection. Single stool specimens were collected at random from 558 school children (308 boys and 250 girls) aged 5–19 years old. Nineteen different parasite species (13 protozoan and six helminths) were detected. Of the children examined, 98.7% (96.5–100%) presented infection with at least one parasite species. The mean prevalence of 27.6% by Fasciola hepatica (range, 5.9–38.2%) was the highest not only with respect to the helminth species found in the Northern Bolivian Altiplano but also among t…

Ocurrence of enteroparasites with zoonotic potential in animals of the rural area of San Andres, Chimborazo, Ecuador.

2021

Abstract Objective The aim of this research was the identification of the enteroparasites harbored by the animals of the San Andres community, to evaluate their role as susceptible hosts and sources of infection for other animals, humans (zoonoses), as well as parasite forms spreaders to the environment in this rural area, located in the province of Chimborazo, Ecuadorian Andean region. Material and methods The study was carried out combining 3 coproparasitological techniques: direct examination, Ritchie and Ziehl-Neelsen in 300 animal stool samples Results Blastocystis sp., Entamoeba spp., Giardia spp., Balantidium spp., Cryptosporidium spp., Ascaris spp., Toxocara spp., Ancylostoma spp., …

15 pages; National audience; Les arthropodes inducteurs de galles sur les végétaux figurent parmi lesherbivores entretenant les relations les plus intimes, et corrélativement les plus étroites, avec leurs plantes hôtes respectives. À cet égard, il semble donc assez naturel de réaliser des inventaires superposables à des unités phytogéographiques caractérisées. Le présent inventaire répond à cette approche en se focalisant sur une unité bien définie, la « Côte bourguignonne » prise au sens large, de Chatillon-sur-Seine à Mâcon, les observations s’étendant à une dizaine d’alliancesphytosociologiques typiques de ces côtes calcaires en ambiance plus ou moins xérothermique.Inventaire entomologiq…

Dialipsis villahermosaeHumala & Selfa n. sp. (Hymenoptera: Ichneumonidae), the second European species of the genus, with biological notes and a …

2009

Abstract The small genus Dialipsis Forster 1869 (Hymenoptera: Ichneumonidae) includes two known species, of which one is common in Central and Northern Europe. Here we describe the male and female of a new species, Dialipsis villahermosae Humala & Selfa, which was reared from mushrooms collected in Eastern Spain. The host fungus gnat, Mycetophila blanda Winnertz, is a new record for the whole genus, while the rate of parasitism seems very low. Based on environmental data of the collection localities and data available for other two species it is suggested that Dialipsis species occur preferably in cool temperatures habitats. A key of identification of the two known Palaearctic species is pr…
