Abstract:

One of the most economic exploitation, widely cultivated, and financially viable non-mulberry silkworms is the eri silkworm (Philosamia ricini). The feeds that eri silkworms consume have a significant impact on their yield and silk production. A study was conducted to assess the growth characteristics of the eco races of the eri silkworm in the circumstances of western region of Tamil Nadu. The Central Muga and Eri Research Institute in Jorhat, Assam provided the eco races of eri silkworm. Three replications of the Completely Randomized Design (CRD) were used to set up the treatments.

Abstract:

Sericulture is the process of cultivating silkworms and extracting silk from them. The caterpillars of the domestic silk moth (also called „Bombyx Mori‟) are the most commonly used silkworm species in sericulture. Other types of silkworms (such as Eri, Muga, and Tasar) are also cultivated for the production of „wild silks‟. Silk is known as the queen of textiles due to its softness, durability, and luster. Furthermore, the silk fibers provide characteristics that are superior toany other type of fiber (e.g., water absorbency, heat resistance, dyeing efficiency, and luster). This textile is obt

Abstract:

Proteinase, a group of enzymes responsible for the breakdown of proteins into smaller peptides and amino acids, plays pivotal role in various biological processes such as digestion, protein turnover and immune function. Eri silkworms, which are known for their silk production, are of great interest not only in the agricultural industry but also from a microbiological perspective due to the diverse microbial community residing in their gut. This investigation spotlights the isolation, characterization and evaluation of enzyme activity of putative proteinase-producing bacteria from eri silkworm.

This study aimed to provide information on the nutrients of the edible larval stage of Gonimbrasia cocaulti (GC) for the first time, while exploring the potential nutrient content of the pupal life stages of the domestic silkworm (Bombyx mori; BM) and the Eri silkworm (Samia Cynthia ricini; SC). The three insects were analyzed for fatty acids, minerals, proximate composition and vitamins. Among the fatty acids, linoleic, a polyunsaturated fatty acid, was approximately threefold higher in GC than in the silkworms. The Ca, Fe and K contents were highest in GC. However, the Zn and Na contents wer

Abstract:

One of the most common foliar diseases in castor cultivation for ericulture is Cercospora leaf spot, caused by Cercospora ricinella Sacc. & Berl. which seriously damages leaves meant as food for eri silkworms. Deterioration in the quality or quantity of castor leaves primarily hampers the health of eri silkworm, which ultimately affects the economic parameters of the cocoons produced by them. A bioassay study was conducted during 2019-2021 at College of Sericulture, Assam Agricultural University, Jorhat, Assam, to check the effects of feeding castor leaves, treated with treatments found pr

Abstract:

Sericulture is an agro-based industry. It is based on cultivation of host plants, rearing of silkworms and production of silk. There are four types of commercial silkworm i.e., mulberry, eri, muga and tasar. Among them, mulberry is only monophagous and the rest are polyphagous. In sericulture, gynandromorphism is too rare. Gynandromorphs are aberrant behaviours or traits that show both male and female features in a certain individual. There are mainly three types of gynandromorph- 1. Bilateral 2. Anterior-posterior 3.

Eri silkworm cocoons (E cocoons) are natural composite biopolymers formed by continuous twin silk filaments (fibroin) bonded by sericin. As a kind of wild species, E cocoons have characteristics different from those of Bombyx mori cocoons (B cocoons). E cocoons have an obvious multilayer (5–9 layers) structure with an eclosion hole at one end and several air gaps between the layers, which can be classified into three categories—cocoon coat, cocoon layer, and cocoon lining—with varying performance indexes.
