“…For example, selection for 'black' lines of YM adults correlated with improved disease resistance (Armitage and Siva-Jothy, 2005;Armitage et al 2003). Selective breeding fixed the 'black' cuticular color in YML over three generations with only a slight reduction in late-stage larval mass (Song et al 2022;and see Huang et al 2011). Selective breeding could thus improve insects' resistance to immune challenges faced in high-density farmed conditions, with concomitant benefits for welfare.…”

Yellow mealworms (Tenebrio molitor; Coleoptera: Tenebrionidae) are currently the most farmed holometabolous insect species in the insects as food and feed industry, with over 300 billion individual mealworms reared annually. Yellow mealworm larvae are being developed for potential uses as human protein, pet, livestock and fish feed, reclamation of mycotoxin-contaminated grains, and more. Insect welfare is of great interest to consumers, producers, and academics; yet no studies have considered the species-specific welfare concerns of farmed yellow mealworms under current industry conditions. Following a model for considering farmed insect welfare, we explore factors related to yellow mealworm welfare in commercial rearing facilities, including: interspecific interactions (including predators, parasites, and pathogens), abiotic conditions (temperature, hydration, atmospheric gasses, lighting), nutrition (including pollutants and hormones), intraspecific concerns (genetics, morphological defects, cannibalism, density, mating and oviposition needs, and handling-associated stress), and slaughter and depopulation methods (including anesthesia). We discuss the current major and minor welfare concerns in the industry and future concerns that may appear as the industry continues to grow. We make recommendations for improving mealworm welfare and discuss future research directions that are necessary to better understand the welfare of this species.

This study aimed to determine the physicochemical, nutritional, antioxidant, and sensory properties of crackers with the addition of edible insects. The analyses covered the contents of total dry matter, crude protein, fat and ash; amino acid composition and antioxidant activity (DPPH method); total polyphenol content; mineral compound composition (AAS); caloric value; and sensory profile (aroma, taste, general appearance, overall acceptability) of the durable pastry—crackers supplemented with 5% of powder of edible insects (cricket, mealworm, and grasshopper). Appropriate research methods were used for analyses. Studies have shown that the contents of dry matter, crude protein, fat and all amino acids detected were higher in the samples with the addition of insects compared to the control sample. The highest antioxidant activity was assayed in the sample with the addition of grasshopper powder. The highest content of total polyphenols was determined in the sample with the addition of mealworm. The addition of insects positively affected the content of mineral substances—especially zinc—in the sample with cricket powder addition. The results of this study show that edible insects are an attractive raw material, which can in future expand the assortment of food products available on the market and increase the nutritional benefits of enriched products.

The yellow mealworm, Tenebrio molitor, is currently one of the most important insect species produced for livestock feed and human consumption. High-density rearing conditions make the risk of disease and infections by parasitic symbionts a challenge in the mass production of these insects. However, certain symbionts are beneficial and should be favoured in order to promote healthy insect populations. Knowledge of parasitic symbionts and their management is essential for the insect rearing industry and its associated research. Here we review the documented microbial infectious agents, invertebrate parasites, and beneficial symbionts occurring in T. molitor. Furthermore, we discuss detection, prevention, and treatment methods for disease management in T. molitor production systems to inform future management and decision making in T. molitor rearing.
