myiasis is the infection caused by a variety of dipterous (fly) larvae in vertebrate’s tissue (man and domestic or wild animals). species of gasterophilus are obligate parasite of horses, donkeys, zebras, elephants and rhinoceroses. there are records worldwide, but mostly, in tropical and subtropical regions. this case report describes a type of gastric myiasis caused by g. intestinalis in an o...

Currently approved irradiation quarantine treatment doses for Bactrocera cucurbitae (Coquillet), melon fly; Ceratitis capitata (Wiedemann), Mediterranean fruit fly; and Bactrocera dorsalis (Hendel), oriental fruit fly, infesting fruits and vegetables for export from Hawaii to the continental United States are 210, 225, and 250 Gy, respectively. Irradiation studies were initiated to determine wh...

In southern California, the sterile insect technique has been used since 1994 to prevent establishment of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). This method involves the continual mass release of sterile flies, which suppress or eliminate any introduced wild fly populations. In addition, Jackson traps baited with trimedlure are deployed throughout the preventative release ...

Wings of various Drosophila melanogaster fly lines were analyzed: the common laboratory fly strain OregonR, inbred fly strains North-Carolina 375 and North-Carolina 399, and wild-caught flies from New Jersey, USA and Cartagena, Colombia. Flies were grown at 22◦C, except otherwise noted. For the temperature experiment, flies were kept at defined temperatures (16◦C, 18◦C, and 28◦C) for two genera...

Wild population of the olive fruit fly (Bactrocera oleae (Rossi.)) was adapted to the laboratory conditions feeding on both olive fruits and an artificial diet. Infested fruits were brought to the laboratory and emerged adults used as the initial generation of the laboratory colony. After eggs were laid into the fruits, they were dissected and first instars were transferred to an artificial die...

Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...

Using the fruit fly Drosophila melanogaster as model host, we have identified mutants of the bacterium Pseudomonas aeruginosa with reduced virulence. Strikingly, all strains strongly impaired in fly killing also lacked twitching motility; most such strains had a mutation in pilGHIJKL chpABCDE, a gene cluster known to be required for twitching motility and potentially encoding a signal transduct...

Environmental adaptation is one of the most fundamental features of organisms. Modern genome science has identified some genes associated with adaptive traits of organisms, and has provided insights into environmental adaptation and evolution. However, how genes contribute to adaptive traits and how traits are selected under an environment in the course of evolution remain mostly unclear. To ap...

CelA is the most abundant enzyme secreted by Caldicellulosiruptor bescii and has been shown to outperform mixtures of commercially available exo- and endoglucanases in vitro. CelA contains both a glycoside hydrolase family 9 endoglucanase and a glycoside hydrolase family 48 exoglucanase known to be synergistic in their activity, connected by three cellulose-binding domains via linker peptides. ...
