Abstract Dermanyssus gallinae (De Geer 1778), commonly named the poultry red mite (PRM), is considered to be the most harmful ectoparasite in poultry farms in Europe. This species feeds on the blood of laying hens, but spends most of its time hidden in cracks and crevices around hen nests. To control PRM populations in poultry houses, chemical pesticides are currently used; however, concern is growing regarding the harmful residues found in eggs and hens, along with the increased resistance of mites ...

Abstract Although increasingly targeted in animal nutrition, black soldier fly larvae or prepupae (BSF, Hermetia illucens L. 1758) require the characterization and modulation of their fatty acid profile to become fully integrated within the feed sector. This improvement will only be possible by the understanding of underlaying biochemical pathways of fatty acid synthesis in BSF. In this study, we hypothesized a labelling of de novo synthesized fatty acids in BSF by the incorporation of deuterated ...

Promoting the cultivation of native legumes, such as faba beans (Vicia faba L.) within the European Union is anticipated to contribute to the sustainability of cropping systems and provide food and feed proteins as alternatives to unsustainable imports. However, efficient alternative control methods to pesticides must be implemented to combat key pests that devalue faba bean seeds (namely, Bruchus rufimanus Boheman, 1833; Coleoptera: Chrysomelidae). This pest causes significant economic losses in ...

Endosymbiotic Wolbachia bacteria are, to date, considered the most widespread symbionts in arthropods and are the cornerstone of major biological control strategies. Such a high prevalence is based on the ability of Wolbachia to manipulate their hosts' reproduction. One manipulation called cytoplasmic incompatibility (CI) is based on the death of the embryos generated by crosses between infected males and uninfected females or between individuals infected with incompatible Wolbachia strains. CI can ...

To address the future challenge of food availability (9 billion people on earth by 2050), non-common sources of proteins need to be investigated. Insects are consumed mainly in Africa, Asia and South America, but entomophagy is now being increasingly promoted in Europe and North America. In addition to consumption in raw form, insects are often cooked, which represents an important guarantee for sanitation purposes. Little information is available on the influence of such treatment and its effect ...
