| Bombyx mori and Bombyx mandarina are morphologically and physiologically similar. In this study, we compared the nucleotide variations in the complete mitochondrial (mt) genomes between the domesticated silkmoth, B. mori, and its wild ancestors, Chinese B. mandarina (ChBm) and Japanese B. mandarina (JaBm). The sequence divergence and transition mutation ratio between B. mori and ChBm are significantly smaller than those observed between B. mori and JaBm. The preference of transition by DNA strands between B. mori and ChBm is consistent with that between B. mori and JaBm, however, the regional variation in nucleotide substitution rate shows a different feature. These results suggest that the ChBm mt genome is not undergoing the same evolutionary process as... |

| En Argentina la sericicultura es una actividad novedosa y es llevada a cabo por pequeños productores como actividad complementaria. La utilización del vigor híbrido en la producción de seda se emplea en la mayoría de los países desarrollados y la productividad y calidad dependen del híbrido involucrado. El objetivo del trabajo es evaluar, en forma preliminar, algunas características productivas de híbridos obtenidos a partir de líneas endocriadas en la Facultad de Agronomía de la Universidad de Buenos Aires. Se utilizaron 4 líneas endocriadas y 6 cruzamientos entre ellas, criadas en condiciones de temperatura y humedad controladas. La alimentación se realizó 4 veces al día con hojas frescas de moreras. En una muestra de 20 individuos, se midieron 4... |

| Mass rearing of parasitoids depends on choosing appropriate alternative hosts. The objective of this study was to select alternative hosts to rear the parasitoid Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera: Eulophidae). Pupae of the lepidopterans Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae), Bombyx mori Linnaeus, 1758 (Lepidoptera: Bombycidae) and Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae) were exposed to parasitism by females of P. elaeisis. The duration of the life cycle of P. elaeisis was 21.60 ± 0.16 and 24.15 ± 0.65 days on pupae of A. gemmatalis and B. mori, respectively, with 100.0% parasitism of the pupae and 71.4 and 100.0% emergence of parasitoids from the first and second hosts,... |

| El gusano de seda de la morera, Bombyx mori (Lepidoptera: Bombycidae), es afectado por numerosas enfermedades como la Grasserie, provocada por el virus de la poliedrosis nuclear (BmNPV). Su manejo y control se dirigen principalmente a la prevención y diagnóstico temprano. El objetivo de este trabajo estuvo encaminado al diagnóstico del virus BmNPV asociado a los síntomas de Grasserie, observados en las crías de gusano de seda en Cuba. Se desarrollaron los métodos de diagnóstico molecular basados en la hibridación radiactiva y no radiactiva de ácidos nucleicos, a partir de extracciones de poliedros de larvas del tercer y cuarto instar. En ambos métodos de hibridación se pudo detectar la presencia de BmNPV. En el caso de la hibridación radiactiva, se... |

| Juvenile hormone analogues have been tested as insect growth regulators in silkworm (Bombyx mori), seeking an increment of silk production. These chemical products, when applied in small or moderate rates, promote the extension of the last larval instar. To understand the physiologic consequences on silk production by the silkworm strain C115 x N108, the application of methoprene, a juvenile hormone analogue, was performed to evaluate its effects on larval development and silk production. Methoprene was topically applied 48h after the fourth larval ecdysis, on the dorsal integument of the 2nd thoracic segment of the insects, at seven rates between 0 and 20 ng a.i. Methoprene influenced positively the duration of the fifth instar and the weight gain of the... |

| Resumen El uso de biomateriales como la quitina y el quitosano ha venido aumentando en los últimos años y con esto sus aplicaciones biotecnológicas. Una fuente alternativa de obtención de estos son los insectos, entre los que se incluye el Bombyx mori L. (gusano de seda). En esta investigación se obtuvieron y caracterizaron quitina y quitosano a partir del Bombyx mori L Hibrido Pilamo 1 que se produce en el departamento de Risaralda, Colombia. Los biomateriales se extrajeron con NaOH al 10 % y HCl 1N y se caracterizaron por infrarrojo (IR-TF), microscopia electrónica de barrido (SEM), espectroscopía de rayos x de energía dispersa (EDS), análisis termogravimétrico (TGA) y calorimetría diferencial de barrido (DSC). El contenido de quitina en las crisálidas... |

| The effect of three genotypes of mulberry, Morus sp. (Moraceae), namely, Miura, FM Shima Miura and IZ 56/4, and three types of rearing substrate comprising compact soil, concrete and plastic screen were estimated on weight and on certain industrial characteristics of Bombyx mori (Lepidoptera) cocoons. Genotype interactions with rearing substrates affected weight of cocoons produced. Analysis showed the best treatments for manufacturer parameters were Miura / compact soil, FM-Shima Miura / plastic screen, IZ 56/4 / compact soil and IZ 56/4 / plastic screen. |

| This study employed a Bac-to-Bac/Bombyx mori bioreactor to mass-produce immunogenic urease subunit B (UreB) from Helicobacter pylori.The signal peptide bombyxin from B. mori was used to promote secretory expression to improve expression levels and was designed and integrated into the UreB gene to generate the Bacmid/BmNPV/(signal peptide)-UreB baculovirus expression system. To determine whether the bombyxin signal peptide resulted in secretory expression of recombinant UreB (rUreB) and to determine the secretory efficiency, we tested the secretory expression level of rUreB in Bm5 cells using ELISA. To further investigate whether secretory expression affected cell viability, cells were evaluated using 0.4% trypan blue staining, and Bacmid/BmNPV/UreB without... |
