Taxonomic and Functional Structure of Benthic and Terrestrial Invertebrates During Wet and Dry Phases of an Intermittent River Within Central Italy

River Research and Applications, EarlyView.
ABSTRACT Temporary rivers and streams are characterized by flow cessation and support high biodiversity of both aquatic and terrestrial species. In this study, we analyzed biological and ecological traits of benthic invertebrates to assess the ecological resilience and resistance of an intermittent river in Central Italy.

Effect of female size on host selection by a koinobiont insect parasitoid (Hymenoptera: Braconidae: Aphidiinae)

European Journal of Entomology, 2009
Body size is a main fitness component of insect parasitoids. We assessed the potential influence of maternal size of the parasitoid wasp Aphidius colemani Viereck (Hymenoptera: Braconidae: Aphidiinae) on its ability to parasitize the different instars of

Rythmes d'activité locomotrice chez deux insectes parasitoïdes sympatriques : Eupelmus orientalis et Eupelmus vuilleti (Hyménoptère, Eupelmidae) [PDF]

Comptes Rendus Biologies 329 (2006) 476-482, 2007
With an automatic image analysis device, we studied the temporal distribution of the locomotor activity of E. orientalis and E. vuilleti during 24 h, and over several days to know whether the activity rhythms of these two Eupelmidae play a role in their competitive interactions. The analysis of locomotor activity rhythms of E.

Generalist predators function as pest specialists: Examining diet composition of spiders and ladybeetles across rice crop stages

Journal of Applied Ecology, EarlyView.
By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...

Pauesia silana Tremblay, 1969 a parasitoid of Cinara-aphids on Conifers in Malta (Hymenoptera: Braconidae: Aphidiinae) [PDF]

, 2009
Pauesia silana is recorded for the first time from Malta and the Lefkada and Meganissi islands in Greece. From Malta, the species was reared from Cinara palaestinensis on Pinus halepensis from material collected from Buskett.

The establishment of Aceratoneuromyia indica (Hymenoptera: Eulophidae) in three biogeographical regions of Argentina [PDF]

, 2006
Specimens of the eulophid Aceratoneuromyia indica (Silvestri) were recovered from fruit fly pupae collected in three Argentinian biogeographical regions. A total of 11 A.

The impact of tree mortality and post‐disturbance management on insect diversity in temperate forests: Insights from a replicated experiment

Journal of Applied Ecology, EarlyView.
Our experiment provides strong evidence for the importance of clustered tree mortality for comprehensive insect diversity in temperate forests and highlights the potential of forest management to enhance insect diversity in homogeneous commercial forests, particularly through the creation of canopy gaps and the retention of deadwood. Both mimic natural

Biology of \u3ci\u3eDiastrophus Nebulosus\u3c/i\u3e (Hymenoptera: Cynipidae) and Its Parasitoid/Inquiline Complex in Galls on \u3ci\u3eRubus Flagellaris\u3c/i\u3e (Rosaceae) [PDF]

, 2018
Rubus flagellaris patches occasionally harbor colonies of compound stem- galls initiated by the cynipid, Diastrophus nebulosus. These isolated colonies host a parasitoid/inquiline complex made up of five principal and three incidental chalcidoid species ...

Biological Flora of Britain and Ireland: Cytisus scoparius*

Journal of Ecology, EarlyView.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Characterizing virulence differences in a parasitoid wasp through comparative transcriptomic and proteomic [PDF]

arXiv
Background: Two strains of the endoparasitoid Cotesia typhae present a differential parasitism success on the host, Sesamia nonagrioides. One is virulent on both permissive and resistant host populations, and the other only on the permissive host. This interaction provides a very interesting frame for studying virulence factors.
