| The objective of this work was to assess, through consumption and utilization of natural food measurements, whether mulberry cultivars, Morus spp., could be recommended to rear the silkworm, Bombyx mori L., in a commercial scale. The mulberry cultivars Miura (standard), Korin and Tailandesa and the hybrids FM 3/3, FM 86, SK 1 and SK 4 were tested. Seventy five fifth-instar commercial hybrid larvae were individualized in gerbox® unities and maintained in a rearing room (25 ± 3ºC and 80 ± 10% RH).The mulberry leaves of each of the five cultivars used to feed the silkworm larvae were submitted to bromatological analysis. The dry weight of larvae at the beginning and at the end of the fifth instar, the food consumed and the feces eliminated were recorded to... |

| Representative strains of Serratia marcescens from an edible cactus plant and silkworms were characterized and a comparison based on their cellular fatty acid composition, 16S rRNA and groE gene sequence analysis as well as silkworm virulence and chitosan susceptibility was carried out. Results from this study indicate that there are no significant differences between the phenotypic and molecular characterization, virulence and chitosan susceptibility of the S. marcescens strains from the cactus plant and silkworms. Silkworms inoculated with S. marcescens from either plant or silkworm resulted in nearly 100% mortality. Chitosan solution exhibited strong antibacterial activity against S. marcescens. This activity increased with the increase of chitosan... |

| ABSTRACT Bombyx mori nucleopolyhedrovirus (BmNPV) disease is one of the most serious silkworm diseases, and it has caused great economic losses to the sericulture industry. So far, the disease has not been controlled effectively by therapeutic agents. Breeding resistant silkworm varieties breeding may be an effective way to improve resistance to BmNPV and reduce economic losses. A precise resistance-detection method will help to accelerate the breeding process. For this purpose, here we described the individual inoculation method (IIM). Details of the IIM include pathogen BmNPV preparation, mulberry leaf size, pathogen volume, rearing conditions, course of infection, and breeding conditions. Finally, a resistance comparison experiment was performed using... |

| The selection of eri silkworm ecorace with high yield and distinct in morphological character is necessary for variety improvement. Five eri silkworm ecoraces, SaKKU1, SaKKU2, SaKKU3, SaKKU4 and SaKKU5 were surveyed and derived in country or from academic cooperation in international level. All ecoraces were cultured using castor leaves of TCO101 variety as food plant at 25±2 °C, 80±5%R.H. Based on morphological characters, there were similar except body of the 5th instar larva of SaKKU1 was covered with white powder and ripe larva showing shiny dominant yellow color. Life cycles were also similar durations, 46-53 days (SaKKU1), 42-53 days (SaKKU2), 42-52 days (SaKKU3), 40-56 days (SaKKU4) and 41-52 days (SaKKU5). SaKKU1 had highest survival rate at larval... |
