| possible involvement of distinct photoreceptors in the photoperiodic induction of diapause in the flesh fly sarcophaga similis. | physiological characteristics of the photoreceptors involved in the photoperiodic induction of diapause were investigated in the flesh fly sarcophaga similis. both the early and late phases of scotophase were sensitive to light and a light pulse during each of these phases prevented diapause. certain physiological differences between the phases were, nevertheless, detected. compared with early scotophase, late scotophase required a light pulse with a long period and a large number of night inter ... | 2009 | 19084533 |
| species composition of forensically important blow flies (diptera: calliphoridae) and flesh flies (diptera: sarcophagidae) through space and time. | weekly monitoring of forensically important flight-active blow flies (diptera: calliphoridae) and flesh flies (diptera: sarcophagidae) was performed using small baited traps. sampling took place in two rural, one suburban and two urban habitats in and around frankfurt (main), germany, lasting two years and eight months. highest values for species richness and chao-shen entropy estimator for shannon's index in both families were found at the urban sites, peaking during summer. space-time interact ... | 2014 | 24529768 |
| muscle attachment site (mas) patterns for species determination in five species of sarcophaga (diptera: sarcophagidae). | to further establish species determination using the muscle attachment site (mas) pattern method, third instar larvae of five forensically important species of sarcophaga meigen were investigated: sarcophaga argyrostoma (robineau-desvoidy), sarcophaga caerulescens zetterstedt, sarcophaga melanura meigen, sarcophaga albiceps meigen and sarcophaga similis meade. as in the previously investigated calliphoridae, patterns were found to be species specific. the main feature of the sarcophaga patterns ... | 2016 | 26391172 |
| upregulation of heat-shock proteins in larvae, but not adults, of the flesh fly during hot summer days. | heat-shock proteins (hsps) are highly expressed when organisms are exposed to thermal stresses. the hsps are considered to play significant roles in thermal adaptation because they function as molecular chaperones facilitating proper protein synthesis. the expression of hsps under field conditions, however, has not been evaluated much, and their importance, based on the ecological contexts in nature, is still unclear. we investigated this aspect in the larvae and adults of the flesh fly, sarcoph ... | 2017 | 28597340 |
| distribution of period-immunoreactive neurons and temporal change of the immunoreactivity under long-day and short-day conditions in the larval brain of the flesh fly sarcophaga similis. | the flesh fly sarcophaga similis show a clear photoperiodic response; they develop into adults under long days, whereas they arrest their development at the pupal stage under short days. although the involvement of a circadian clock in photoperiodic time measurement is suggested in this species, the anatomical location of the clock neurons responsible for the time measurement has been unknown. we detected two period-immunoreactive cell clusters in the larval brain; one cluster was located at the ... | 2017 | 28414547 |
