barbary partridge meat quality as affected by Hermetia illucens and tenebrio molitor larva meals in feeds
Food Research International, 2018Co-Authors: Giulia Secci, Fulvia Bovera, G Moniello, Laura Gasco, Giuliana ParisiAbstract:Abstract A partial substitution (25 or 50%) of dietary protein with Tenebrio molitor (TM) and Hermetia illucens (HI) meals as protein sources in the diet of Barbary partridge (Alectoris barbara) has been tested in terms of raw and cooked meat quality. Twelve partridges per feeding group (control - SBM, HI25, HI50, TM25 and TM50) were slaughtered. The peeled carcasses of the HI25, HI50, TM25 and TM50 groups were heavier than those of the SBM group, both raw and cooked. The pH, color and shear force of the raw meat were not affected to any greater extent by the diet, whereas the presence of insect meal seemed to increase the yellowness index of the cooked meat. The proximate composition was unaffected by both the species and the level of insect meal, although the fatty acid profile was changed considerably. The HI and TM groups had significantly higher C18:1n-9 and lower C16:0 contents than SBM. Furthermore, Hermetia illucens, added as 50% of the dietary protein, induced a significant increase in C12:0 and C16:1n-7. As a result, the highest AI and TI were obtained for the HI50 diet (0.38 and 0.75, respectively), whereas the TM groups both had intermediate AI values (around 0.35) and the lowest TI (0.67). Finally, the cholesterol content of the birds was not affected by insect inclusion in the feeds.

laying performance blood profiles nutrient digestibility and inner organs traits of hens fed an insect meal from Hermetia illucens larvae
Research in Veterinary Science, 2018Co-Authors: Fulvia Bovera, Rosa Loponte, M I Cutrignelli, Pietro Lombardi, Giuseppe Vassalotti, M E Pero, Serena Calabro, Nadia Musco, Valentina Panettieri, G PiccoloAbstract:Abstract Given probable the increment in the nutritional needs of both humans and animals, animal production will have increased dramatically by 2050. Insect meals could be an alternative protein source for livestock, and they would also be able to reduce the environmental problems related to intensive animal production system. The aim of this study was to evaluate productive performance, blood analysis, nutrient digestibility, and changes in the internal organs of laying hens fed Hermetia illucens larvae meal (HI) at two different levels in substitution (25 or 50%) of soybean meal (SBM). A total of 162 Hy-line Brown hens (sixteen weeks old) were equally divided into three experimental groups and fed isoprotein and isoenergetic diets. Egg weight, feed intake, and feed conversion rate were not affected by the soybean meal substitution at both inclusion levels of insect meal. Egg mass was positively affected by the insect meal diets, as was the lay percentage, although only at the lowest inclusion level. Dry matter, organic matter, and crude protein digestibility coefficients were lower for the HI50 diet, probably due to the negative effect of chitin. A reduction in serum cholesterol and triglycerides was observed in both insect-meal fed groups, while serum globulin level increased only at the highest level of insect meal inclusion, and, consequently, the albumin to globulin ratio decreased. Overall, a protein replacement of 25% with an insect meal from Hermetia illucens larvae in the diet of laying hens seems to be more suitable and closer to the optimal level.

in vitro crude protein digestibility of tenebrio molitor and Hermetia illucens insect meals and its correlation with chemical composition traits
Italian Journal of Animal Science, 2015Co-Authors: S Marono, Rosa Loponte, Carmelo Di Meo, Yosry A Attia, Giovanna Piccolo, Antonino Nizza, Fulvia BoveraAbstract:The aims of this study were to evaluate the correlation between in vitro crude protein digestibility coefficients of insect meals from Tenebrio molitor (TI) and Hermetia illucens (HI) and their chemical composition traits as well as to develop regression equations able to estimate the in vitro crude protein digestibility (CPd) from proximate analysis of insect meals. Twelve samples of insect meals (6 from TM larvae, TM 1-6 and 6 from HI larvae, HI 1-6) were obtained from different producers and analysed for chemical composition and in vitro crude protein digestibility by a two-step enzymatic method (digestion with pepsin and trypsin-enriched pancreatin). For both insect meal samples, CPd was negatively correlated to ADF and chitin contents, while just for HI there was a positive correlation (P<0.01) between CP percentage of the samples and CPd. For both insect meals the former variable chosen in the stepwise analysis was the chitin, explaining the 79.45% of CPd variability for Tenebrio molitor samples and the 98.30% for Hermetia illucens . In the second step, the amount of protein linked to ADF was added in the model for T. molitor and CP for H. illucens samples. The coefficients chitin is the main constituent of insect body able to affect the crude protein digestibility of Tenebrio molitor and Hermetia illucens larvae meals estimated by an in vitro enzymatic method.

Environmental impact of food waste bioconversion by insects: Application of Life Cycle Assessment to process using Hermetia illucens
Journal of Cleaner Production, 2017Co-Authors: Roberta Salomone, G. Saija, Alessia Giannetto, Salvatore Fasulo, Gabriele Mondello, Davide SavastanoAbstract:Food waste management strategies are mainly focused on waste minimization, but the search for new solutions to waste valorization is also a viable and potentially advantageous alternative. In this context, the aim of this study is to assess the potential environmental impacts of food-waste bioconversion into compost and dried larvae through the action of Hermetia illucens, by applying Life Cycle Assessment (LCA). In international scientific literature, there are many studies concerning the utilization of insects for food-waste bioconversion, but very few articles relate to the application of LCA in this sector and none of these refers to Hermetia illucens. Furthermore, the process of bioconversion through Hermetia illucens is a very attractive option, considering that it represents a potential valuable solution to two problems: food waste management on the one hand and, on the other, the rising global demand for feed (dried larvae can be used in aquaculture feed production) or the competition between land use for energy crops and for food crops (dried larvae are a fat-rich resource potentially usable for the production of biodiesel). In particular, the LCA results presented in this study refer to the assessment of the potential environmental impacts of a pilot plant in which H. illucens is employed for food-waste treatment. From 10 tonnes of food-waste input, 300 kg of dried larvae and 3,346 kg of compost are produced. Three different functional units were used to carry out the analysis: the input of the production process, therefore 1) food-waste; the output composed of dried larvae, for which 2) the protein content (fundamental characteristic for using this product in aquaculture) and 3) the lipid content (to be used for biodiesel production) are considered. Results related to the functional unit of 1 tonne of food waste treated show a value of 30.2 kg CO2 eq in terms of Global Warming Potential, 215.3 MJ in terms of Energy Use, and 0.661 m2a in terms of Land Use. When compared with alternative sources of raw material for feed or biodiesel, these results show that the most significant benefits of insect production are connected to Land Use, while Energy Use is the main burden, and the estimation of Global Warming Potential is still affected by many uncertainties.

Hermetia illucens as a new and promising species for use in entomoremediation.
The Science of the total environment, 2018Co-Authors: Piotr Bulak, Cezary Polakowski, Adam Waśko, Katarzyna Nowak, Dariusz Wiącek, Andrzej BieganowskiAbstract:Abstract This study investigated the use of Hermetia illucens (black soldier fly - BSF) larvae as a new species for use in entomoremediation. The H. illucens larvae effectively reduced the dry mass of polluted corn leaves by an average of 49% after 36 days for both Cd and Zn (50 mg·kg−1), which is a better result than that, which can be obtained by one of the standard proposed pretreatments for biomass polluted after phytoextraction: composting. The presence of heavy metals did not significantly affect the dry mass utilization efficiency. Based on this, we proposed the use of H. illucens as a new post-harvest management method of phytoextraction-polluted biomass. Cadmium mostly accumulates in the puparium, while Zn accumulates in the adults. The high Cd content in the puparium further creates possibility of its application in the metal recovery process. It is also proposed that the general definition of entomoremediation be expanded.

Immune response in the larvae of the black soldier fly Hermetia illucens
ISJ-Invertebrate Survival Journal, 2016Co-Authors: Agnieszka Zdybicka-barabas, Piotr Bulak, Cezary Polakowski, Andrzej Bieganowski, Adam Waśko, Małgorzata CytryńskaAbstract:The black soldier fly Hermetia illucens is an ecological decomposer used for biodegradation of organic waste. Its larvae can develop on a wide range of decaying plant and animal matter, including manure and food scraps, i.e., habitats that are extremely rich in various microorganisms. Living in such conditions requires very well-functioning immune mechanisms. However, the immune response processes have not been examined so far in H. illucens larvae. In order to shed light on the immune system in the black soldier fly, in the present study we have examined H. illucens hemocytes and analyzed the effects of immune challenge of H. illucens larvae on the activity of the key components of insect humoral immune response, i.e., phenoloxidase, lysozyme, and antimicrobial peptides.

The first report of the physicochemical structure of chitin isolated from Hermetia illucens
International journal of biological macromolecules, 2016Co-Authors: Adam Waśko, Piotr Bulak, Cezary Polakowski, Magdalena Polak-berecka, Katarzyna Nowak, Andrzej BieganowskiAbstract:This is the first report on the physicochemical properties of chitin obtained from larvae and imagoes of black soldier flies (Hermetia illucens). Scanning electron microscopy revealed differences in surface morphologies of the two types of chitin. The crystalline index values of chitins from adult flies and larvae were 24.9% and 35%, respectively. This is a trait that differentiates these biopolymers from chitins extracted from other sources described so far. X-ray diffraction patterns and IR spectroscopy revealed that both types of samples of chitin were in an α crystalline form. Also, the results of elemental analysis, thermal stabilities and FTIR spectroscopy of the chitins from larvae and adults of H. illucens were similar, which points to a general similarity in their physicochemical structure.

The use of HIML led to a more favorable (P < 0.01) feed conversion ratio in hens but lay percentage, feed intake, average egg weight, and egg mass were higher (P < 0.01) in hens fed the SBM diet. Hens fed insect meal produced a higher percentage of eggs from small (S), medium (M), and extra-large (XL) classes (P < 0.01) than SBM, while the SBM group had a higher percentage of eggs from the large (L) class (P < 0.01). The levels of globulin and albumin to globulin ratio were, respectively, higher and lower (P < 0.05) in HILM than the SBM group. Cholesterol and triglycerides were higher (P < 0.05 and P < 0.01, respectively) in hens from SBM than in the HILM group. Blood levels of Ca were higher (P < 0.01) in hens fed insect meal, while creatinine was higher (P < 0.01) in blood of hens fed SBM. Hermetia illucens larvae meal can be a suitable alternative protein source for laying hens even if the complete replacement of soybean meal needs further investigation to avoid the negative effects on feed intake.

Bioactive Compounds from Hermetia illucens Larvae as Natural Ingredients for Cosmetic Application.
Biomolecules, 2020Co-Authors: Cíntia Almeida, Patrícia Rijo, Catarina RosadoAbstract:Due to the sustainable organic matter bioconversion process used as substrate for its development, the Hermetia illucens (Linnaeus) larvae biomass is considered a source of compounds with high aggregate value and quite a promising market. The materials that can be extracted from H. illucens larvae have opened the door to a diverse new field of ingredients, mainly for the feed and food industry, but also with potential applicability in cosmetics. In this review we succinctly describe the larval development and rearing cycle, the main compounds identified from different types of extractions, their bioactivities and focus on possible applications in cosmetic products. A search was made in the databases PubMed, ScienceDirect and Web of Science with the terms ‘Hermetia illucens’, ‘bioactives’, ‘biochemical composition’ and ‘cosmetics ingredients’, which included 71 articles published since 1994.
