Earthworms and their cutaneous excreta can modify the virulence and reproductiv...
Chelkha, Maryam; Blanco-Pérez, Rubén; Vicente-Díez, Ignacio; Bueno-Pallero, Francisco; Amghar, Souad; El Harti, Abdellatif; Campos-Herrera, RaquelEarthworms are ecological engineers that can contribute to the displacement of biological control agents such as the entomopathogenic nematodes (EPNs) and fungi (EPF). However, a previous study showed that the presence of cutaneous excreta (CEx) and feeding behavior of the earthworm species Eisenia fetida (Haplotaxida: Lumbricidae) compromise the biocontrol efficacy of certain EPN species by reducing, for examp...
Vegetation drives assemblages of entomopathogenic nematodes and other soil orga...
Campos-Herrera, Raquel; Blanco-Pérez, Rubén; Bueno-Pallero, Francisco Ángel; Duarte, Amílcar; Nolasco, Gustavo; Sommer, Ralf J.Entomopathogenic nematodes (EPNs) are widely distributed in soils throughout the world. Their activity as biological control agents is modulated by abiotic and biotic factors (e.g. soil type, climatic fluctuation and natural enemies). We sought to identify soil properties in a Mediterranean region, which might be managed to enhance biological control agents’ services provided by EPNs. We hypothesized that respon...
Reproductive efficiency of entomopathogenic nematodes as scavengers. Are they a...
Blanco-Pérez, Rubén; Bueno-Pallero, Francisco Ángel; Neto, Luis; Campos-Herrera, RaquelEntomopathogenic nematodes (EPNs) and their bacterial partners are well-studied insect pathogens, and their persistence in soils is one of the key parameters for successful use as biological control agents in agroecosystems. Free-living bacteriophagous nematodes (FLBNs) in the genus Oscheius, often found in soils, can interfere in EPN reproduction when exposed to live insect larvae. Both groups of nematodes can...
Effects of cover crops on the overwintering success of entomopathogenic nematod...
Jaffuel, Geoffrey; Blanco-Pérez, Rubén; Büchi, Lucie; Mäder, Paul; Fließbach, Andreas; Charles, Raphaël; Degen, Thomas; Turlings, Ted C.J.Conservation agriculture is arising as an alternative to conventional agriculture with the aim to have a reduced impact on the environment. This includes the use of cover crops to conserve soil quality by limiting soil erosion, adding organic matter, and enhancing soil nutrient content, as well as water availability, which are all factors that can greatly influence the presence of soil organisms. In the current...
