Microorganism Contribution to Mass-Reared Edible Insects: Opportunities and Challenges.

The interest in edible insects' mass rearing has grown considerably in recent years, thereby highlighting the challenges of domesticating new animal species. Insects are being considered for use in the management of organic by-products from the agro-industry, synthetic by-products from the plastics industry including particular detoxification processes. The processes depend on the insect's digestive system which is based on two components: an enzymatic intrinsic cargo to the insect species and another extrinsic cargo provided by the microbial community colonizing-associated with the insect host.

Effect of different diet composition on the fat profile of two different black soldier fly larvae populations.

Black soldier fly larvae (Hermetia illucens; BSFL) can transform organic wastes into nutritional biomass useful in animal feeding. The aim of this work was to study the effect of five diets (meat, fruit, vegetable substrates, a mix of them and control) on the profile of fatty acids (FAs) and sterols of BSFL. For a more exhaustive characterization of the nutritional properties, the profile of esterified FAs in the sn-2 position of the triglycerides, the most absorbed lipid component during animal digestion was evaluated.

Performance of Hermetia illucens (Diptera: Stratiomyidae) larvae reared on organic waste diets and pupal chitin and chitosan yield.

Recently, much research has been oriented towards the influence of different food wastes and agricultural by-products on the final larval biomass and chemical composition of the insect species Hermetia illucens L. (Diptera: Stratiomyidae). However, there is a gap in the literature regarding the possible relationship between the feeding substrate of H.

De Novo Genome Assembly at Chromosome-Scale of (Diptera Stratiomyidae) via PacBio and Omni-C Proximity Ligation Technology.

is a species of great interest for numerous industrial applications. A high-quality reference genome is already available for . However, the worldwide maintenance of numerous captive populations of , each with its own genotypic and phenotypic characteristics, made it of interest to perform a de novo genome assembly on one population of to define a chromosome-scale genome assembly.

Chitosan as a Control Tool for Insect Pest Management: A Review.

Chitosan, a polysaccharide derived from the deacetylation of chitin, is a versatile and eco-friendly biopolymer with several applications. Chitosan is recognized for its biodegradability, biocompatibility, and non-toxicity, beyond its antimicrobial, antioxidant, and antitumoral activities. Thanks to its properties, chitosan is used in many fields including medicine, pharmacy, cosmetics, textile, nutrition, and agriculture.

Predation Capacity of the Banded Thrips for the Biological Control of the Onion Thrips .

The onion thrips, , is a main insect pest for many field crops worldwide, with a particular preference for the species of the genus . is a banded thrips, whose larvae are considered the primary native predator of . Due of their predatory behaviour, larvae are considered a good candidate for biological control against thrips pests.

Evaluation of a quasi-dimeric eugenol derivative as repellent against the stored grain insect pest Sitophilus oryzae (Coleoptera Curculionidae).

Background: Essential oils (EOs) and their chemical components are often proposed as an alternative to synthetic pesticides for pest control of foodstuff insect pests. However, their low persistence and strong, spicy odour, make them poorly suitable for use to protect food. Modification of the EOs components molecules increases their molecular weight and reduce their volatility.
