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.

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.

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.

The cell cycle time of the haemocytes in the insect Calliphora vicina

Journal of Insect Physiology, 1979
The cell cycle time of Calliphora vicina prohaemocytes was examined using the labelled mitoses method after the administration of a pulse of H3-thymidine. The total cycle time occupied 9.1 hr, while G1 + 12M, S and G2 + 12M occupied 1.6 hr, 2.7 hr and 4.8 hr respectively.

[Functional morphology of blowfly Calliphora vicina hemocytes].

Tsitologiia, 2013
In the hemolymph of Calliphora seven types of hemocytes were revealed. These are prohemocytes, which are the stem cells, stable and unstable hyaline cells, thrombocytoids, spindle cells, juvenile plasmatocytes and plasmatocytes I-IV, which represent sequential stages of one cell line differentiation were registered.

Barbiturates and Analgesics in Calliphora vicina Larvae

Journal of Forensic Sciences, 1997
Abstract Calliphora vicina larvae were reared on artificial foodstuffs spiked with a range of concentrations of aspirin (acetylsalicylic acid), sodium salicylate, paracetamol, sodium aminohippurate, amphetamine sulfate, and the barbiturates thiopentone, phenobarbitone, amylobarbitone, barbitone, and brallobarbitone. Larvae were harvested

On the metabolic fate of ecdysone and 3-dehydroecdysone in Calliphora vicina

Insect Biochemistry, 1973
Abstract The metabolism of ecdysone in white prepupae of Calliphora vicina is analysed. Ecdysone is hydroxylated to ecdysterone with a half-life of 2 hours. Both hormones are then converted into more polar products with a half-life of 12 hours. As a side reaction both ecdysone and ecdysterone are oxidized to 3-dehydroproducts.

Free Amino Acids in the Haemocytes and Plasma of the Larva of Calliphora Vicina

Journal of Experimental Biology, 1974
ABSTRACT Free amino acid concentrations have been measured in haemolymph samples taken from 3rd instar larvae of the blowfly, Calliphora vicina, at various stages prior to pupariation. The amino acids found in the haemocyte fraction only accounted for 6% of the total free amino acid concentration of the haemolymph.

Structural and functional aspects of sense organs on the maxillary palps of Calliphora vicina

Journal of Insect Physiology, 1976
Abstract The maxillary palps of the blowfly Calliphora vicina Robineau-Desvoidy are shown to bear, in addition to long mechanoreceptive hairs, small sensilla basiconica ccontaining three neurons. The electrical responses obtained with a simple qualitative olfactometer indicate an olfactory function.

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 ...
