  The edible insects are consumed as an alternative animal protein source by most Asian countries. Since there is a limited evidence for their safety particularly from microbiological aspects, an attempt was made to assess the microbial population of Tenebrio molitor L. samples in laboratory conditions. Primary stocks were purchased from a local market, in Sari- a city in north of Iran. Microbial samples were prepared from both body surfaces and guts of insect. Samples were individually and cultured on nutrient agar (NA), incubated at taken 270C for 24-72h. Distinguished colonies were isolated and purified. Based on phenotypic characteristics, hypersensitive response (HR) on geranium leaves, as well as 16S rRNA gene sequencing analysis, the isolates were categorized into two groups. The pathogenic isolates were identified as Bacillus cereus, Staphylococcus sp, Pseudomonas aeruginosa, Enterobacter asburiae, Bacillus firmus and Serratia marcescens. Whereas, the nonpathogenic bacteria were assigned as Enterobacter cloacae and Bacillus thuringiensis. Undoubtedly, the presence of pathogenic microbes in the microflora of mealworm larvae by direct and indirect consumption of insect may pose a threat to human and animal health. These findings suggest an implementation of certain processing methods in order to decrease or eradicate risks of microbial contamination of diets using natural insects. Manuscript profile

  Increasing the volume of the world's major challenges facing resource constraints and rising food and protein prices. Using insects as food and feed for humans, livestock and poultry can be a good solution to this global crisis. Yellow flour cream is one of the most common sources of high-quality protein, used to feed small animals, birds, and fish. In this study, five different in vitro diets (25 1 1 ° C and 60 5 5 relative humidity, 16: 8 h light period (brightness: dark)) were used to grow yellow worm. In this study, wheat bran was considered as control. The results showed that the intrinsic growth rate, as well as the finite rate, increased significantly in the treatment of wheat and chopped wheat compared to the control, and the wheat and chopped wheat diet significantly increased the net and gross population growth rate, respectively, But the diet of cardboard and powdered bread reduced these two parameters significantly compared to the control. Therefore, the diet of cardboard and powdered bread had negative effects on the biological characteristics of yellow worm and wheat and chopped wheat diet had positive effects on the biological properties of a yellow worm. In general, the results of this study showed that the cultivation of yellow worm on different diets has significant effects on the life cycle of yellow flour, and wheat and shredded wheat can be a suitable diet in the future at a much lower cost and with less effort to grow worms. Yellow flour to be used.   Manuscript profile
