Rearing of silkworm is highly dependent on environmental variations. To have a healthy cocoon production, it is necessary to have a proper temperature and humidity controlled house for silkworm rearing. Temperature, humidity and fresh air should be managed to get a wonderful silk product. An ideal temperature of 23°C to 28°C and humidity in between 65% to 85% is to be maintained. IoT based silkworm rearing house consists of sensors and actuators, which are interfaced with a low power controllers. The Sericulture unit can be equipped with a wireless sensor node to sense the real time Temperature and Humidity [1], also necessary actuators to control these environmental parameters. The color change in the body of the worms indicates the different stages and the light yellowish indicates that they have reached to the cocoon stage and the morphological changes in silkworm structure can be used to detect abnormal worms[2].The proposed framework introduces an Internet of Things (IoT) empowered Wireless Personal Area Network (WPAN) system. The received image is first segregated into two classes as diseased or healthy by analyzing the histogram of the background removed image based on thresholding. Again the diseased class will be sub classified into 2 diseases as either Flacherie or Pebrine by applying suitable mask for extracting worm and obtaining the histogram of the worm and analyzing it. The result will be sent to the farmer via E-mail. The proposed system could be a probable solution for productivity in silkworms.

This paper is focused on Sericulture which denotes to the rearing of silkworm to produce silk. Parameter like Temperature, Humidity and light intensity are the important factors in the progression of silkworms and suitable encouraging must be done according requisites in every stage. Sericulture alludes to the raising silkworms to deliver silk; India is the second highest producer of silk in delivering 15% of the aggregates silk creation alongside China. Silk is called the queen of tensile properties. Although there are several commercial species of silkworm monitoring is a greatest challenge for the farmer. Silk worms in every stage, especially during the development of larva. Disinfection is one of the reproving parameters to be considered for healthy and successful silk worm rearing, sericulture is the significant occupation in the country side of India. Hence there exists the need of using innovation in sericulture cultivate .Aim of our project is to protect the silkworms from the proper environmental parameters and making the system automated. Automated sericulture system using IOT is to detect the temperature, Humidity, air quality, rain, etc.., through buzzer and automatically switching on exhaust fan and lights. In this project we use mq2 sensor to detect smoke which produces noise through the buzzer. The temperature, water and humidity sensor are also used to sense the parameters respectively and shows real time updates to the user of the server. The sericulture system use to get affected by the existing methods with more human interventions. Our method is automated which can reduce the work of the people. And this system can be used as the base to many other projects like baby monitoring system, green house monitoring system, mushroom and broccoli monitoring system.

Cutibacterium acnes is a causative agent of inflammatory skin diseases and systemic infections. Systemic infections caused by C. acnes are difficult to treat, and the development of a systemic infection model for C. acnes would be useful for elucidating the mechanisms of infection and searching for therapeutic agents. In this study, we established a silkworm infection model as a new experimental system to evaluate the interaction between C. acnes and the host, and the efficacy of antibacterial drugs. Silkworms infected with C. acnes died when reared at 37 °C. The dose of injected bacterial cells required to kill half of the silkworms (LD50) was determined under rearing conditions at 37 °C. The viable cell number of C. acnes was increased in the hemolymph and fat body of the infected silkworms. Silkworms injected with autoclaved C. acnes cells did not die during the study period. The survival time of silkworms injected with C. acnes was prolonged by the injection of antibacterial drugs such as tetracycline and clindamycin. These findings suggest that the silkworm C. acnes infection model can be used to evaluate host toxicity caused by C. acnes and the in vivo efficacy of antimicrobial drugs.

Spider silk is one of the best natural fibers and has superior mechanical properties. However, the large-scale harvesting of spider silk by rearing spiders is not feasible, due to their territorial and cannibalistic behaviors. The silkworm, Bombyx mori, has been the most well known silk producer for thousands of years and has been considered an ideal bioreactor for producing exogenous proteins, including spider silk. Previous attempts using transposon-mediated transgenic silkworms to produce spider silk could not achieve efficient yields, due to variable promoter activities and endogenous silk fibroin protein expression. Here, we report a massive spider silk production system in B. mori by using transcription activator-like effector nuclease-mediated homology-directed repair to replace the silkworm fibroin heavy chain gene (FibH) with the major ampullate spidroin-1 gene (MaSp1) in the spider Nephila clavipes. We successfully replaced the ∼16-kb endogenous FibH gene with a 1.6-kb MaSp1 gene fused with a 1.1-kb partial FibH sequence and achieved up to 35.2% chimeric MaSp1 protein amounts in transformed cocoon shells. The presence of the MaSp1 peptide significantly changed the mechanical characteristics of the silk fiber, especially the extensibility. Our study provides a native promoter-driven, highly efficient system for expressing the heterologous spider silk gene instead of the transposon-based, random insertion of the spider gene into the silkworm genome. Targeted MaSp1 integration into silkworm silk glands provides a paradigm for the large-scale production of spider silk protein with genetically modified silkworms, and this approach will shed light on developing new biomaterials.

In the current era of highly developed science, technology and technology, the demand for natural fabrics is increasing year by year in the world market, and the world silk industry and science are led to the cultivation of mulberry varieties with high nutritional value and the creation of breeds and hybrids suitable for different seasons of the changing external environment. In recent years, in the Republic of Uzbekistan, the practice of rearing mulberry silkworms several times a year has been used. However, there are no breeds and hybrids suitable for the hot summer conditions of our country, based on this, scientific research has been started in the direction of creating heat-resistant breeds at the Silk Research Institute. In this article, the results of the breeding of 6 breeds and 4 different industrial hybrids of mulberry silkworm under hot conditions are described. Based on preliminary data, Line 1 and Line 2 systems were found to have high embryonic and post-embryonic viability under hot summer conditions. However, the average cocoon weight of these systems was 1.68-1.73 g, cocoon shell weight was 339 mg, and cocoon silkiness was 19.6-20.2%. Based on the obtained results, it was concluded that Line 1 and Line 2 systems can be used as initial selection material for creating heat resistant breeds.

Mulberry (Morus L.) is an economically important tree being cultivated for its leaves to rear the silkworm Bombyx mori. Rearing of silkworm is an art and science popularly known as sericulture; an agrobased cottage industry provides employment to millions in China, India, Korea, Vietnam, etc. Mulberry is a perennial tree that maintains high heterozygosity due to the outbreeding reproductive system. It is recalcitrant to most of the conventional breeding methods, yet considerable improvement has been made in leaf yield and leaf quality. Conventional breeding in mulberry is a tedious, labour intensive and time taking process, which needs to be complemented with modern biotechnological methods to speed up the process. This article enumerates the problems, challenges, constraints and achievements in mulberry breeding along with recent advances in biotechnology and molecular biology to enable mulberry breeders to tackle specific problems more systematically and effectively.
