Teneral laboratory-bred Glossina palpalis flies were successfully fed through bat's wing membrane on defibrinated blood by means of a technique developed in this laboratory. Using this technique almost 100% of the flies engorged blood through the membrane. Ten to fifteen flies were kept in Standard 'Geigy 10' or 'Geigy 15' cages and records were kept of mortality and the weights of the pupae pr...
The activities of four oxidative enzyme systems, including NADH oxidase, succinate-cytochrome c reductase, NADH-cytochrome c reductase, and cytochrome c oxidase, were compared in mitochondrial-microsomal preparations from wing epidermis and fat body of diapausing Samia Cynthia pupae, presumptively non-diapausing S. Cynthia ricini pupae which were caused to diapause by removal of the brain, and ...
Active peptide from shark liver (APSL) is a cytokine from Chiloscyllium plagiosum that can stimulate liver regeneration and protects the pancreas. To study the effect of orally administered recombinant APSL (rAPSL) on an animal model of type 2 diabetes mellitus, the APSL gene was cloned, and APSL was expressed in Bombyx mori N cells (BmN cells), silkworm larvae and silkworm pupae using the silk...
Surveys of pupae and larvae of black flies (Diptera: Simuliidae) were carried out in Thua Thien Hue Province of central Vietnam, and Lam Dong Province of southern Vietnam in 2014. A total of 26 species belonging to the genus Simulium were collected, consisting of eight known species, one newly recorded species, and 17 new species (of which three species of the subgenus Nevermannia were describe...
For mass production of human epidermal growth factor (hEGF), silkworm baculovirus expression vector system (BEVS) was adopted in this study. hEGF gene was in-frame fused with polyhedrin (Ph) gene under the control of Ph promoter and was used to co-transfect BmN cell with the modified Bombyx mori baculovirus DNA to obtained recombinant virus. The ELISA showed a maximum expression on day 4 in lar...
Eight transgenic strains of Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) were compared with the wild-type parental laboratory strain (P95) in colony. Measurements of average weight of pupae, percentage of adults emerging from pupae, ratio of males to total emerged adults, and mating competitiveness were analyzed. The parental strain colony was subcultured and exposed to handling ...
Predation is an important factor in the dynamics of gypsy moth (Lymantria dispar L.) populations, yet predation rates can be difÞcult to estimate accurately in the Þeld. Biased estimates can result from spatial heterogeneity in risk or from artifacts associated with deploying prey. Here we compare predation rates on freeze-dried gypsy moth pupae afÞxed with beeswax to pieces of burlap withpreda...
We purified a novel serine protease with a molecular mass of 26 kDa from Sarcophaga pupae. This protease appeared almost exclusively in the yellow body, an organ that develops temporarily in the pupae of dipteran insects and expands to form the adult midgut by engulfing the larval midgut. cDNA analysis revealed that this protease consists of 239 amino acid residues and has significant structura...
