عارضه میازیس همواره در نتیجه تخم گذاری و لاروگذاری مگس های گروه سیکلوراف و رشد متعاقب آنها در انساج بدن ایجاد می شود. با آنکه بقای لارو این مگس ها در طبیعت متکی به حضور دام های اهلی و حیات وحش می باشد ولی بالغین اینگونه مگس ها در محوطه های دامداری، پارک ها و همچنین بر روی زباله ها و شاخ و برگ برخی از گیاهان و درختچه هایی که از نظر شهد و گرده برای این گروه از حشرات مناسب می باشند، یافت می شوند و...
We describe here a rare case of traumatic myiasis occurred in August 2014, caused by an association of 2 Diptera species, Sarcophaga tibialis Macquart (Diptera: Sarcophagidae) and Lucilia sericata (Meigen) (Diptera: Calliphoridae), in a domestic cat in northern Italy. Species identification was based on adult male morphology. The present case is the first report of S. tibialis as an agent of my...
A lectin was purified from the hemolymph of Sarcophaga peregrina larvae, obtained after injury of their body wall. This lectin agglutinated sheep red blood cells markedly and the hemagglutinating activity was inhibited by galactose and lactose. The active lectin was found to have a molecular weight of 190,000 and to consist of four alpha subunits and two beta subunits, with molecular weights of...
Indirect chilling injury commonly occurs during long-term exposure to low temperature in many organisms including insects. A previous study revealed increased rates of survival and reduced cold injury in flesh flies, Sarcophaga crassipalpis, that experienced an intermittent pulse of high temperature during a low-temperature regiment. We extended these studies by determining survival rates and A...
We chose the larvae of fleshfly Sarcophaga bullata to map the peptide and protein immune response. The hemolymph of the third-instar larvae of S. bullata was used for isolation. The larvae were injected with bacterial suspension to induce an antimicrobial response. The hemolymph was separated into crude fractions, which were subdivided by RP-HPLC, gel electrophoresis, and free-flow electrophore...
Pupal diapause (dormancy) in the flesh fly, Sarcophaga bullata, is induced by short-day photoperiods and low temperature. In this study, the inheritance mode of diapause was investigated by crossing a nondiapausing (nd) strain of S. bullata with 2 diapausing strains having different diapause capacities. The results consistently indicated that diapause incidence is inherited in a simple Mendelia...
Change in chromatin structure of a developmentally regulated gene of Sarcophaga peregrina (flesh fly) during development was investigated. This gene (25-kDa protein gene) was specifically activated in the fat body, but not the hemocytes of larvae in the middle of the third instar. The mRNA level in the fat body decreased thereafter, reaching one-fifth of the maximum level in the late third inst...
A new potent antibacterial protein, for which we propose the name royalisin, was found in royal jelly of the honeybee Apis mellifera L. and purified to homogeneity for the first time by acid extraction, gel filtration, and reverse-phase high pressure liquid chromatography. The primary structure of royalisin was determined to consist of 51 residues, with three intramolecular disulfide linkages, ...
