Changes in polypeptides pattern of haemolymph, midgut, ovary and salivary glands of female mosquito A. stephensi were studied when fed upon anti-mosquito haemolymph antibodies. The expression of almost all polypeptides was reduced in haemolymph and ovary of the immune fed mosquitoes as compared to control. However, there was no significant difference in case of midgut and salivary glands. Seven...

The effects of high temperature on cationic composition of haemolymph of the three selected races of the silkworm, Bombyx mori, viz., PM, NB4D2 and CSR2 during 4 moult and 5 instar larval development were th th investigated. Haemolymph cation levels increased significantly throughout the feeding period from 1 to 6 day st th in all the three races and showed a significant decrease on 7 day. Mg a...

Haemolymph Na+, Cl~, K+, Mg, Ca, Cu and protein levels, in vivo postbranchial acid-base status (total CO2, pH and PCOt), in vitro haemolymph buffer value, Bohr value and oxygen affinity were measured before and after a 31-week period in which control crayfish were maintained at normoxia and experimental crayfish were maintained at an ambient oxygen tension of 50-55 torr. Analysis of haemolymph ...

BACKGROUND In this study the haemolymph components of infected and none infected Lymnaea gedrosiana with xiphidiocercaria larvae was compared. METHODS Five hundred Fifty Lymnaea snails were collected from Ilam and Mazandaran provinces, Iran, during 2008-2009. The snails were transported to the lab at Tehran University of Medical Sciences and their cercarial sheddings were studied. Haemolmyphs...

Male sagebrush crickets, Cyphoderris strepitans, offer an unusual nuptial food gift to females during copulation: females feed on the hindwings of males and ingest haemolymph seeping from the wounds they inflict. Previous work has shown that females prevented from wing feeding during initial copulations are more receptive to subsequent matings than females permitted to wing feed. In the present...

The hydrocarbons in extractable lipids of haemolymph from healthy and diseased larvae of the Japanese beetle (Popillia japoniea) have been characterized. Haemolymph contains at least 21 saturated hydrocarbons having from 21 to 27 carbon atoms. Normal, monomethyl-branched, and dimethylbranched alkanes with even and odd carbon numbers were identified. Tricosane (12%), ll-methyltricosane (19%), 9,...

We have investigated the pattern of metabolic changes during tethered flight with and without lift generation in the African fruit beetle Pachnoda sinuata. Two distinct metabolic phases occur during lift-generating flight. The first phase is characterised by a high rate of oxygen consumption and a rapid change in proline and alanine levels in the haemolymph and flight muscles and in glycogen le...

Larvae of Culex tarsalis, a mosquito, are capable of surviving and developing in dilutions of sea water ranging from 0 mosmol l-1 to 700 mosmol l-1. In waters more dilute than 400 mosmol l-1, the larvae osmoregulate, whereas in those more concentrated than 400 mosmol l-1, the osmotic strength of the haemolymph parallels that of the medium, i.e. the larvae osmoconform. Over the full range of ext...

argyrophilic staining of nucleolar organizer regions (agnor) has been considered to be useful in the diagnosis and prognostic evaluation of different cutaneous tumors. in order to evaluate the role of the agnor technique in discriminating aggressive from non-aggressive basal cell carcinoma (bcc), paraffin-embedded histologic sections from 30 cases of aggressive bcc (bcc2) and 30 cases of non-ag...

Low temperature tolerance is the main predictor of variation in the global distribution and performance of insects, yet the molecular mechanisms underlying cold tolerance variation are poorly known, and it is unclear whether the mechanisms that improve cold tolerance within the lifetime of an individual insect are similar to those that underlie evolved differences among species. The accumulatio...
