“…Increased weight for silkworms reared in the Non-Domestic system (3.83g) compared to those of Domestic rearing (2.49g) is probably due to the last two factors mentioned previously. According to Samami et al (2019), the performance of silkworm production plays a key role in the sericulture industry. Still, larger larvae may have more potential in silk production, since the sericigenic glands can represent up to 30% of the silkworm's body weight (Oliveira et al 2010).…”

“…Smaller cocoons can be observed from food restriction of the silkworms, diseases, between different breeds and even from the quality and dimensions of the place where the larvae spin the cocoons, called mountages. Larger cocoons are more appreciated than smaller ones, in addition the good quality cocoon represents the main economic factor in silkworm farms (Samami et al, 2019). Samami et al (2019) evaluated eight different hybrid silkworms and observed fresh cocoon weights from 1.473g to 1.587g.…”

Objetivou-se avaliar a produção e qualidade de lagartas, pupas e casulos de bicho-da-seda em diferentes sistemas de criação no Brasil. Foram utilizadas 240 lagartas híbridas de Bombyx mori L. no terceiro instar, divididas em dois tipos de sistemas, o Doméstico e Não Doméstico, totalizando 120 animais por sistema. No Doméstico eram criadas em caixas de papel e manejo não tecnificado. En- quanto, no Não Doméstico eram criadas em barracão de criação sericícola, manejo assistenciados e tecnificados. Para realização de análises foram coletas de ambos os sistemas de criação, 40 lagartas no último dia do quinto ínstar e 60 casulos no terceiro dia após o início da construção dos mesmos. Foi observado melhor produção e qualidade para as medidas observadas nas lagartas (peso da lagarta e peso da glândula sericígena), nos casulos (peso do casulo, peso da casca sérica, largura e comprimento do casulo) e nas pupas (peso de pupas) para os bichos-da-seda criados no sistema Não Doméstico. Nenhuma diferença foi observada para casulos desclassificados, teor de seda liquida e pupas mortas. Entretanto, estes parâmetros impactam diretamente sobre o lucro do sericicultor. Com base nos resulta- dos obtidos, recomenda-se apostar na criação do bicho-da-seda no sistema Não Doméstico, onde se obtém casulos de melhor qualidade e com maior teor de seda líquida.

“…Mulberry leaves are the only natural food source in terms of Bombyx mori nourishment. Mulberry leaves represent both the source of water and the source of nutrients necessary for growth and development stages [22]. The availability of the silkworms' nourishment source is limited; specifically, it is available only in the spring-summer season.…”

Since ancient times, honey has been considered one of the most illustrious and esteemed natural products. Honey plays two key roles; specifically, it is an appreciated nutritional product, and also exhibits a wide range of beneficial properties for human health as a therapeutic agent. Furthermore, it has been shown that honey has valuable effects on the biological and physiological features of mulberry silkworms (Bombyx mori). Bombyx mori exhibits importance not only for the economy, but it also serves as an important biotechnological bioreactor for the production of recombinant proteins that have a great impact in the medical field and beyond. It also represents an important model organism for life sciences. In view of the fact that silk fibroin serves as a natural biopolymer that displays high biocompatibility with human organisms and due to honey’s various and remarkable properties for human health, the two elements are currently used together in order to develop ideal biomaterials for a wide range of purposes. In this review, by discussing the applicability of honey on Bombyx mori and beyond, the importance of honey for life sciences and related fields is spotlighted.

“…The mulberry silkworm B. mori is a monophagous insect, obtain all the needed nutrients for its development from the mulberry leaves. The goodness of silk produced by the silkworm counts on environmental conditions as well as the quality of yield of mulberry leaves that plays a very influential role in producing cocoons with high quality (Legay, 1958, Etebari et al 2004and Samami et al 2019 Recently, many researchers have made attempts to progress the quality and quantity of mulberry leaf over foliar application on leaf matrix with either use of some natural products (Sudhakar et al, 2000;Hiware, 2006, Nguku et al, 2007and Kamel et.al. 2016 or artificial compounds (Shankar and Rangaswamy, 1999;Mamatha et al, 2006;Rahmathulla et al, 2007 andBhattacharyya et al 2016) Supplements of nutrition e.g., vitamins, proteins, amino acids and probiotics when added to larval feed tend to elevate nutritional adequacy and economic feature of silkworm (Etebari and Matindoost, 2005;Singh et al, 2005and Amalarani et al, 2011and Balasundaram et al 2013 Probiotics are the live microbial food additions, advantageously affecting the host by enhancement of the microbial balance and improved the development and the cellular growth.…”

The present investigation was conducted to study the effect of fortification of mulberry leaves with different concentrations of baker's yeast Saccharomyces cerevisiae extract and blue-green algae Spirulina platensis extract on some quantitative parameters of Bombyx mori larvae and cocoons. Statistical analysis of the obtained data revealed that all larval treatments showed a significant increase in the larval and cocoon weights, especially at concentrations 0.5 % of yeast and 0.05% of spirulina. Feeding 5 th larval instar with mulberry leaves at concentrations 0.5 % yeast and 0.05% spirulina, lead to increase the larval weight by about 55 % and 30%, respectively, when compared with the control. The same trend was observed in pupal weight, cocoon weight and cocoon shell weight. Larval treatments with yeast extract at concentration 0.5% increased the weights of pupa (0.850 gm), cocoon (0.908 gm) and cocoon shell (0.216 gm) by about 30%, 16% and 27% as compared with controls which were 0.561gm, 0.781gm and 0.170 gm, respectively. On the other hand, all larval trials with spirulina extracts remained at the second grade of implementation on the pupal weight, cocoon weight and shell weight. However, feeding B. mori larvae with yeast extract significantly increased the silk ratio and the total haemolymph protein comparing with the spirulina treatments or control ones.
