| seasonal patterns of arthropods occurring on sheltered and unsheltered pig carcasses in buenos aires province (argentina). | differences in the succession of insects and other arthropoda (invertebrate animals with jointed legs), on domestic pig carcasses placed under a roof and under the open sky have been studied in buenos aires province, argentina (latitude 34 degrees 45's) in all the seasons of the year. faunal associations proved different for each treatment in winter: the common bluebottle calliphora vicina was found in both, but on the sheltered carcass cochliomyia macellaria and the rare phaenicia cluvia were f ... | 2002 | 11955835 |
| forensically important calliphoridae (diptera) associated with pig carrion in rural north-central florida. | a study to determine the relative abundance and seasonality of forensically important blow flies (diptera: calliphoridae) in rural north-central florida was conducted using pig carcasses (sus scrofa l.) as models for human bodies. seven species of calliphoridae were collected: lucilia coeruleiviridis (=phaenicia) (macquart), cochliomyia macellaria (f.), chrysomya rufifaces (macquart), phormia regina (meigen), chrysomya megacephala (f.), and a few specimens of calliphora livida hall, and callipho ... | 2007 | 17547239 |
| thermoregulation in larval aggregations of carrion-feeding blow flies (diptera: calliphoridae). | the growth and development of carrion-feeding calliphorid (diptera: calliphoridae) larvae, or maggots, is of great interest to forensic sciences, especially for estimation of a postmortem interval (pmi). the development rate of calliphorid larvae is influenced by the temperature of their immediate environment. heat generation in larval feeding aggregations (=maggot masses) is a well-known phenomenon, but it has not been quantitatively described. calculated development rates that do not include i ... | 2007 | 17547240 |
| incidence of myiasis in panama during the eradication of cochliomyia hominivorax (coquerel 1858, diptera: calliphoridae) (2002-2005). | we present the results of a study on myiasis in panama during the first years of a cochliomyia hominivorax eradication program (1998-2005), with the aim of investigating the behavior of the flies that produce myiasis in animals and human beings. the hosts that registered positive for myiasis were cattle (46.4%), dogs (15.3%), humans (14.7%), birds (12%), pigs (6%), horses (4%), and sheep (1%). six fly species caused myiasis: dermatobia hominis (58%), phaenicia spp. (20%), cochliomyia macellaria ... | 2007 | 17923994 |
| species composition and seasonal succession of saprophagous calliphorids in a rural area of córdoba: argentina. | during 2004, four experiments were carried out, one each season, in order to determine the species composition and seasonal dynamics of calliphoridae in a rural area of córdoba (argentina). two pigs (sus scrofa l.), weighing approximately 8 kg each, were used in each experiment. they were killed with a blow to the head and immediately placed in a variant of the schoenly et al. (1991) trap. one pig was exposed in the shade and the other one under direct sunlight. the insect fauna was collected da ... | 2007 | 18064353 |
| insect succession and decomposition patterns on shaded and sunlit carrion in saskatchewan in three different seasons. | a study was conducted on decomposition and insect succession in the prairie ecozone of saskatchewan in the year 2000. eighteen domestic pig carcasses (42-79 kg) were employed as human models for applications to future homicide investigations in this region. two major variables were considered including the effect of season and habitat (sun versus shade). research was conducted over 25 weeks, spanning three seasons: spring, summer and fall. ambient temperature, internal carcass temperature, fauni ... | 2008 | 18662603 |
| a preliminary study of insect fauna on pig carcasses located in sugarcane in winter in southeastern brazil. | minimum post-mortem intervals can be estimated based on analyses of the pattern of insect succession on a carcass. in order to successfully apply this approach, insect development rates must be considered with regard to local regional climatic conditions. this study is the first to analyse insect succession on carcasses decomposing in a sugarcane crop in brazil. in all seasons, chrysomya albiceps (wiedemann) (diptera: calliphoridae) and cochliomyia macellaria (fabricius) were frequent visitors d ... | 2009 | 19493195 |
| a checklist of calliphoridae blowflies (insecta, diptera) associated with a pig carrion in central brazil. | although the cerrado is the second major brazilian biome, few studies have been undertaken about its entomofauna. blowflies have an important role in forensic entomology, helping in the determination of postmortem intervals. the main goal of this exploratory study was to identify and to catalog the blowfly species associated with a pig carcass. the study was conducted in a pasture in brasília, distrito federal. a pig (sus scrofa) was killed with a .22 caliber shot in the frontal region of the he ... | 2010 | 20666916 |
| a comparison of blow fly (diptera: calliphoridae) and beetle (coleoptera) activity on refrigerated only versus frozen-thawed pig carcasses in indiana. | to have large numbers of replicates in forensic entomology research, it is often necessary to freeze carcasses and thaw them before use in experiments. research on the effects of freezing on decomposition is minimal in the literature and the effect that it has on insect (e.g., blow fly, beetle) activity is virtually unknown. the objective of this study was to compare the differences in insect activity occurring on refrigerated only versus frozen-thawed pig carcasses, and to characterize the asso ... | 2011 | 22238884 |
| dispersal and distribution of calliphoridae (diptera) immatures from animal carcasses in southern louisiana. | spatial distributions of calliphorid pupae (based on adult emergence) from swine carcasses located in woods and pasture were determined during 4 seasons in southern louisiana. adult emergence was substantially greater in pastures than woods for all seasons except winter. secondary screwworm, cochliomyia macellaria (f.), was the predominant calliphorid species collected ( > 95%) during summer and fall; whereas, black blow fly, phormia regina (meigen), was the primary species (86%) during spring. ... | 1996 | 8699464 |
| effects of temperature and tissue type on the development of cochliomyia macellaria (diptera: calliphoridae). | the secondary screwworm, cochliomyia macellaria (fabricius), was reared on either equine gluteus muscle or porcine loin muscle at 20.8 degrees c, 24.3 degrees c, and 28.2 degrees c. c. macellaria needed approximately 35% more time to complete development when reared at 20.8 than 28.2 degrees c. furthermore, larval growth and weight over time did not differ between larvae reared on equine versus porcine muscle. this study is the second in the united states to examine the development of c. macella ... | 2010 | 20939391 |
