Cytotoxic activity of blowfly Calliphora vicina hemocytes

Journal of Insect Physiology, 2004
The cytotoxic activity of hemocytes isolated from larvae of the blowfly Calliphora vicina was tested using human myelogenous leukemia K562 cells as target. Both single cell and cytotoxicity assays demonstrated that the hemocytes recognize the K562 cells as nonself, firmly attach to their surface and induce target destruction in a manner resembling the ...

Amitriptyline Accumulation and Elimination in Calliphora vicina Larvae

The American Journal of Forensic Medicine and Pathology, 1997
Calliphora vicina larvae reared on artificial foodstuffs spiked with human equivalent therapeutic (100 ng/g), toxic (300 ng/g), lethal (500 ng/g), and 10 x lethal (5,000 ng/g) concentrations of amitriptyline and nortriptyline, alone and in various combinations, were harvested at various stages of development and analysed for drug content by high ...

Impact of paracetamol on Calliphora vicina larval development

International Journal of Legal Medicine, 2004
This paper demonstrates that blowfly larval development is slightly impacted by paracetamol if present in the rearing foodstuff particularly during days 2-4 of development. Since paracetamol and similar analgesic drugs are involved in a large number of overdose deaths each year this information is of importance where blowfly growth is used to estimate ...

Drug accumulation and elimination in Calliphora vicina larvae

Forensic Science International, 1995
Calliphora vicina larvae were fed on drug-laden muscle from three suicides involving amitriptyline, temazepam and a combination of trazodone and trimipramine; triplicate daily harvestings were analysed. The limit of detection for all four drugs was 0.01 micrograms drug/g larvae.

The photoperiodic clock in the blowfly Calliphora vicina

Journal of Insect Physiology, 1990
Abstract The blowfly, Calliphora vicina Meigen (Diptera: Calliphoridae), displays a maternally induced larval diapause. The critical nightlength for adult flies at 23.5°C and larvae derived from eggs deposited on days 10–14 and maintained in darkness at 11°C, is about 10 h 45 min and thus about 1 h longer than at 20°C.

Retention of Human Body Fluids in Adults of Calliphora vicina (Diptera: Calliphoridae)

Journal of medical entomology, 2021
Foraging by Calliphora vicina Robineau-Desvoidy often leads to a period of bubbling behavior, followed by either deposition of the regurgitate onto surfaces or reuptake of the bubble.

Landmark-free morphometrics reveals sexual dimorphism in shape and integration of tagmata in the forensically important blowfly Calliphora vicina

Zoological Journal of the Linnean Society
Phenotypic integration has been shown to influence the degree and direction of organismal evolution in vertebrates. Comparatively fewer multivariate analyses of shape have been conducted in invertebrates, partly due to difficulties in identifying ...

The pattern of reactivation of diapausing larvae in the blowfly, Calliphora vicina

Journal of Insect Physiology, 1974
Abstract In Calliphora vicina from Belomorsk (North Karelia) the pattern of reactivation of diapausing larvae at different temperatures (4, 12·5, 15·5, 20, and 25°C) was studied experimentally. Most favourable in this respect are the first and last temperatures. Photoperiodic reactivation was established.

Impact of submergence on the survival of the later immature stages of the forensically significant blow fly Calliphora vicina R.-D. (Diptera: Calliphoridae)

Journal of Forensic Entomology
The impact of submergence on the survival of blow flies (Diptera: Calliphoridae) and its implications in estimates of the post-colonization interval have been relatively understudied in forensic entomology.

On the Mechanism of Proboscis Extension in the Blowfly Calliphora Vicina

Netherlands Journal of Zoology, 1976
Proboscis extension, resulting from adequate taste stimulation of tarsal chemoreceptors was studied in the blowfly. It was found, by means of electromyography of the musculus retractor fulcri, that contraction of this muscle causes the rostrum to be rotated out of the head-capsule. The muscle is a protractor muscle.
