Insect farming is growing in popularity, and in addition to insect meal, it generates waste products such as exuviae and frass, which can be recycled in agriculture. The aim of this incubation experiment was to evaluate the effect of Tenebrio molitor L. frass on selected chemical and biological properties of deacidified peat, which is widely used in horticulture. The optimal rate of frass fertilizer in peat for growing vegetables and ornamental plants was determined, with special emphasis on mineral nitrogen levels. Peat was fertilized with five nitrogen rates, 0, 50, 100, 200, and 400 mg dm−3, and supplied with frass or urea. The study demonstrated that frass can be used as organic fertilizer. An increase in the nitrogen rate significantly increased mineral nitrogen content and electrical conductivity and decreased Ca content in peat. Both frass and urea increased the ammonification rate at the beginning of incubation and the nitrification rate from the second week of the experiment. Higher frass rates (5 and 10 g dm−3) increased the content of plant-available nutrients (nitrogen, phosphorus, magnesium, potassium, and sodium) in peat as well as the abundance of microorganisms supporting organic matter mineralization. Unlike frass, urea increased the counts of nitrogen-fixing bacteria in peat.

“…The resultant suspension was subsequently diluted at a 1:10 ratio in peptone water enriched with 1% TSB (Triptic soy broth, Merck, Germany) and then incubated at 30°C for 4 h before being employed in the API tests, following the manufacturer's guidelines. The biochemical and carbon source tests were further incubated at 30°C for 24 h (Przemieniecki et al, 2022).…”

Due to global warming, the rice weevil is an increasing threat. Various species of weevils coexist with endosymbiotic Sodalis pierantonius. This study aimed to check whether different chemical properties of different cultivars of common wheat and barley grain cause disturbances in insect feeding and rearrangements of the rice weevil microbiome. It has been observed that foraging increases in the case of cultivars with low protein content, high steric acid content, and low antioxidant activity. Cultivars with higher antioxidant activity, a tendency was observed to increase the number of adult insects and the intensity of feeding. However, the correlation of number of offspring generations and antioxidants was different depending on species of cereals (R 2 =0.9 for barley, R 2 <0.1 for wheat). Changes of dominance classes of selected Enterobacteriaceae partially shifted the microbiomes of insects feeding on different barley varieties. In contrast, in some wheat cultivars, displacement of the dominant genus Sodalis by genera Staphylococcus or Mammaliicoccus was observed, severely reducing the rice weevil's foraging ability. Nevertheless, Sodalis sp. almost always dominated (from 16.7 to 90.07% for wheat and from 63.4 to 90.9% for barley), and no correlation was observed between species and variety factors of cereals and their abundance.K e y w o r d s: storage pests, Sodalis sp., grain properties, symbiotic bacteria, Sitophilus oryzae

Through efficient digestion involving micro-organisms, the insect mass can be utilized for feed and fertilizer purposes [14].

In this study, we compared the digestibility levels and in vitro fermentation parameters of total mixed rations (TMRs) containing 20% and 40% defatted black soldier fly (Hermetia illucens) larvae (BSF) as a substitute for soybean meal (SBM) in the basal ration (60% roughage/40% concentrated feed) of dairy cows. We evaluated the volatile fatty acid (VFA), total gas production, methane emission, ammonia, pH, carbon dioxide, in vitro dry matter digestibility (IVDMD), and neutral detergent fiber digestibility (IVNDFD) of the TMR0 (basal), TMR20 (20% BSF included), and TMR40 (40% BSF included) diets at the end of 24 and 48 h of incubation. Significantly lower levels of ammonia formation were found in the TMR20 and TMR40 groups at 24 and 48 h (p < 0.001). An increase in total VFA levels was observed in the TMR0 group at 24 h (p < 0.001). The highest IVDMD was determined in TMR20 and TMR40 at 24 h. The highest IVNDFD value was observed in TMR20 at 24 h and in TMR40 at 48 h. The substitution of 20% and 40% of SBM with BSF positively affected IVDMD and IVNDFD (p < 0.001). TMR20 and TMR40 had the highest cumulative gas production at 48 h of incubation (p < 0.05). In conclusion, the use of BSF had a positive impact on digestibility and in vitro rumen fermentation. Therefore, we recommend the use of BSF in formulating dairy cow rations.
