Phenoloxidases in larval cuticle of the blowfly, Calliphora vicina

Insect Biochemistry, 1981
Three different phenoloxidases have been purified from the cuticle of mature larvae of the blowfly, Calliphora vicina. Enzyme A is a typical tyrosinase (EC 1.10.3.1., o-diphenol: O2 oxidoreductase). It oxidizes both monophenols and o-diphenols, is inactive towards p-diphenols, and is readily inhibited by thiourea and phenylthiourea. Enzymes B and C are

Influence of food substrates on the development of the blowflies Calliphora vicina and Calliphora vomitoria (Diptera, Calliphoridae)

Parasitology Research, 2013
The blowflies Calliphora vicina and Calliphora vomitoria are among the first colonizers of human remains in Europe. Laboratory development studies with immature stages of these blowflies for postmortem interval (PMI) calculations are generally performed on different media such as processed food substrates or liver of various animals.

Calcium distribution during egg development in Calliphora vicina

Journal of Insect Physiology, 1984
Abstract Calcium distribution during egg development in Calliphora vicina has been measured by atomic absorption spectroscopy. When female flies are fed meat, their calcium content rises and then remains stable throughout egg development. As the ovaries accumulate calcium, there is a corresponding decrease in the calcium content of the Malpighian ...

Some conformational studies of larval cuticular protein from Calliphora vicina

Insect Biochemistry, 1979
Protein extracted from lipid-free late instar larval cuticles of Calliphora vicina consists of a mixture of similar proteins which, when in solution (phosphate buffer pH 6 or 0.05 M NaCl), exist largely in a disordered conformation as shown by infrared (IR) and optical rotary dispersion (ORD) data. ORD showed the presence of about 13% α-helical and 20%

Darkness as factor influencing the oviposition delay in Calliphora vicina (Diptera: Calliphoridae)

Journal of Forensic and Legal Medicine, 2016
Many environmental and intrinsic factors (e.g. limited access to the body) can disrupt insect activity, causing a delay in the colonization of a corpse. These elements could hinder an accurate estimation of the minimum Post-mortem Interval (minPMI), raising questions about the limits of forensic entomology.

Purification of Prophenoloxidase in the Haemolymph ofCalliphora vicina(R. & D.)

Archives Internationales de Physiologie et de Biochimie, 1979
An improved method for the purification of prophenoloxidase is described. The proenzyme was purified 400 fold in homogenous form. The purity was tested by disc-electrophoresis and the molecular weight was found to be 87 000 in comparison to the mobility of marker enzymes, which were run simultaneously in SDS-gel electrophoresis.

Geographical and diapause-related cold tolerance in the blow fly, Calliphora vicina

Journal of Insect Physiology, 1998
Three geographical strains of the blow fly, Calliphora vicina, were tested for cold tolerance at 0 degrees, -4 degrees and -8 degrees C. Survival to eclosion after 1 to 18 days of cold exposure was greater for diapause-destined larvae than for nondiapause-destined larvae of the two northern strains (Nallikari, Finland 65 degrees N and Edinburgh ...

[Hemocytes of Calliphora vicina larvae. I. Histological analysis].

Tsitologiia, 2004
The rational classification of blood cells of a blowfly Calliphora vicina larva has been worked out basing on the studies of hemocyte morphology and their dynamics while ageing. Eight morphological cell types can be found during the third age in larva's hemolymph.

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.

Tarsal Taste Discrimination in the Blowfly, Calliphora Vicina Robineau-Desvoidy

Netherlands Journal of Zoology, 1971
This paper deals with the problem of the specificity of the sense cells in terminal tarsal taste sensilla on the forelegs of the blowfly, Calliphora vicina Rob.-Desv. (= Calliphora erythrocephala Meigen), in relation to the discrimination these flies are capable of making, as judged by their behavioural responses, between water and weak sugar (sucrose)
