In the present study, nutritional composition and growth parameters of yellow mealworm, Tenebrio molitor L. (Coleoptera: Tenebrionidae) larvae were evaluated after 30 days of feeding using different food materials i.e. Wheat as (diet 1) , oats (diet 2) , chicken 21% (diet 3)-corn Stover (diet 4) , oats + wheat bran (diet 5) , oats + corn stover (diet 6) , oats + chicken feed 21% (diet 7) , wheat + corn stover (diet 8), wheat bran + chicken feed 21% (diet 9) , chicken feed 21% + corn stover (diet 10)-and the last diet is a mixture of the previous four ingredients (wheat bran + corn stover + chicken feed 21% + oats (diet 11). For growth parameters, yellow mealworm larvae fed on Wheat as (diet 1)oats (diet 2)chicken feed 21 % and mixture of them have the highest values in specific growth rate and feed conversion efficiency .Nutritional analysis showed significant differences of contents between tested diets; Where the analysis showed the highest percentage of protein and fat when the larvae fed Diet 3 and 1 On the other hand ,highest level of crude fiber occurred when larvae fed on corn Stover and wheat + corn stover. In general, yellow mealworm mass rearing using Wheat, oats, chicken feed 21 % and mixture of them showed a good result on growth rate and nutritional composition.

http://www.eje.cz Morales-Ramos et al. (2011) formulate an optimal composition of the diet for larvae of T. molitor based on choice tests. This diet consists of 80% wheat bran and 20% potato fl akes (60% carbohydrates, 32% protein and 8% fat) and results in optimal larval growth. However, when larvae are not given a choice, different diets result in optimal growth. The optimum no-choice diet consists of 90% wheat bran and 10% potato fl akes (64% carbohydrates, 29% protein and 7% fat) (Morales-Ramos et al., 2011). Further optimization resulted in an increase in adult fecundity, but no improvement in food utilization effi ciency, growth, development time or survival during the larval stage. The requirement for protein is confi rmed by both Oonincx et al. (2015) and van Broekhoven et al. (2015). They show that larvae have higher survival rates and shorter development times when fed high protein diets (> 20%). Several studies provide a more in-depth assessment of the nutritional The effects of the particle size of four different feeds on the larval growth of Tenebrio molitor (Coleoptera: Tenebrionidae)
Evaluation of various commodities for the development of the yellow mealworm, Tenebrio molitor
Scientific Reports
We evaluated the suitability of forty-four commodities (i.e., cereal flours and meals, non-flour, cereal commodities, legumes and various commodities of vegetative and animal origin) as oviposition and feeding substrates for the yellow mealworm, Tenebrio molitor. Τen T. molitor adults were introduced in plastic vials containing 30 g of each commodity. At the end of the 1 week period, all adults were removed, and mortality was determined; then the vials were further incubated for additional 9 weeks. After this time, the vials were opened, and the larvae of each vial were separated from the feeding substrate, counted and weighed as a group. The efficiency of ingested food conversion was calculated for each substrate. Finally, proximate composition was calculated to determine the nutrient components of the feeding substrates tested and the T. molitor larvae that fed on various selected substrates. In general, adult reproduction was clearly favoured by most amylaceous substrates tested,...
Development of larvae Tenebrio molitor L. (Coleoptera: Tenebrionidae), in different diets aiming at the production of insects for animal feed (Atena Editora), 2024
The use of insects as ingredients in feed can be promising in the animal nutrition chain, providing a source of nutrients of excellent quality. The aim is to evaluate the development of larvae of tapeworms (Tenebrio molitor L. and Zophobas morio L, Coleoptera: Curculionidae) raised on diets with different amounts of corn bran in order to reduce the production costs of this insect for animal consumption. The experiments will be conducted at the Arthropod Ecology and Behavior Laboratory (LECOM) at the Agricultural Engineering and Sciences Campus (CECA), in an air-conditioned room at 28±2ºC, RH of 70±10% and a 12-hour photophase. The insects will be fed a standard diet consisting of corn and wheat-based growth feed. Pieces of sweet potatoes, potatoes and fresh carrots will be fed to the insects every 48 hours as a source of moisture. The experiment will be conducted in a completely randomized design with five treatments and five replications. The control treatment consists of the same standard insect feeding diet in the laboratory maintenance colony and the other treatments will consist of the addition of corn and wheat-based growth ration to the standard diet. The parameters evaluated will be: duration of the larval period, between oviposition and pupa formation; pupal period, period between pupa formation and adult hatching; and the weight of the pupae, which were weighed individually on a precision scale. For statistical analysis, data means will be subjected to analysis of variance at a significance level of 5%.

In this study, nutritional profiles and growth performances of yellow mealworm, Tenebriomolitor larvae (TML) were assessed cultivated using common food wastes i.e. watermelon rinds, broilers' eggshells and banana peels. Nutritional profiles and growth performance of TML were evaluated after 28-day feeding trial. Post-feeding proximate analysis showed significant increment of nutritional contents compared to the control groups; whereby TML demonstrated highest level of crude protein (43.38%±2.71), moisture (9.74%±0.23) and ash (4.40%±0.22) in the group treated with watermelon wastes. On the other hand, TML showed highest level of crude fibre (8.73%±0.05) when treated with broilers' eggshells; and higher level of crude fat (40.13%±4.66) with banana wastes. Nitrogen-free extract (NFE) contents were also noticed higher in the group treated with banana wastes (4.46%±5.30). In terms of growth performance, TML administrated with watermelon wastes demonstrated superior in specific growth rate (2.50%±0.43) and feed conversion efficiency (0.10%±0.01). Interestingly, TML grown with banana wastes showed highest survival rate (97.5%) among all. In short, TML cultivation using watermelon and banana wastes showed a promising result on nutritional fortification and growth enhancement.
Growth Optimization and Rearing of Mealworm (Tenebrio molitor L.) as a Sustainable Food Source
Foods
As a sustainable food source for humans, mealworms (Tenebrio molitor) have a great deal of potential, due to the fact that they have a very favorable nutritional profile and a low environmental impact. For meal production, feed formulation and optimization are important. The mealworm Tenebrio molitor (Coleoptera: Tenebrionidae) is the most consumed insect in the world. Mealworms were given a variety of diets, including wheat bran as constant diet supplemented with different levels of Ospor (Bacillus clausii) at 0.002 g, 0.004 g, 0.006 g, and 0.008 g; imutec (Lacticaseibacillus rhamnosus) at 0.2 g. 0.4 g, 0.6 g, and 0.8 g; fungi (Calocybe indica) at 250 g, 500 g, and 750 g; yeast (Saccharomyces cerevisiae) at 50 g, 100 g, and 150 g; and wheat bran (standard diet) were examined in complete randomized design (CRD). Different parameters, i.e., the larval, pupal, and adult weight, size, life span, and nutritional profile of mealworm were studied. When compared with other insect growth pr...

The aim of this study was to evaluate five agro-industrial byproducts (apricots, brewer’s spent grains, brewer’s spent yeast, feed mill byproducts including broken cereal grains, and hatchery waste including eggshell debris, fluff, infertile eggs, dead embryos, and egg fluids) or mixtures thereof as food diets of Ephestia kuehniella (Zeller), Tenebrio molitor (L.), and Hermetia illucens (L.). Eleven out of 26 tested combinations allowed the first instar larvae to reach the adult stage. Results showed that bioconversion parameters and biomass composition can vary depending on the diet composition, especially in the case of E. kuehniella and H. illucens, whose nutritional requirements seem more complex than those of T. molitor. Tenebrio molitor was able to develop in almost all byproducts. However, only when T. molitor was fed with suitable mixtures of byproducts the development parameters were similar to those obtained with the standard diet. The best results in terms of bioconversio...
