Insect Haemolymph Proteins

1990
Publisher Summary This chapter discusses the structure and function of major groups of hemolymph proteins that are common to all insects, storage proteins, lipoproteins, vitellogenins, and inducible antibacterial proteins. It also discusses some proteins and peptides that are present in smaller amounts, sometimes occurring only in a few insect ...

Haemolymph pressure in certain cirripedes

Journal of Experimental Marine Biology and Ecology, 1986
Abstract Haemolymph pressure has been measured in the mantle sinus of several balanomorph barnacles and the peduncular sinus of two lepadomorph species. The absolute pressure of balanomorphs was found to be similar to that recorded for other crustaceans. The absolute pressure of lepadomorphs was much higher than that in balanomorphs.

Antigenic components in Triatoma infestans haemolymph

Journal of Insect Physiology, 1972
Abstract Immunoelectrophoretic experiments were made of the antigenic composition of Triatoma infestans haemolymph, taking instar and feeding into consideration. Haemolymph from adult male insects against antiserum to haemolymph of T. infestans, revealed between 14 and 17 antigenic components.

Haemolymph gases and buffers in Ascaris lumbricoides

Comparative Biochemistry and Physiology Part A: Physiology, 1974
Abstract 1. 1. When worms were collected and exsanguinated in the abattoir the haemolymph gave the following data: pH 6 · 71 (S.D. ± 0 · 13), p CO 2 158 (S.D. ± 47 ·) Torr, and p O 2 26 (S.D. ± 13· 0) Torr. 2. 2. When the parasites were kept in saline there were no significant changes in p O 2 but pH and p CO 2 changed to 6 · 88 units

The carbohydrate levels of insect haemolymph

Comparative Biochemistry and Physiology Part A: Physiology, 1977
Abstract 1. 1. Several species of insects and terrestrial arthropods were analysed for levels of carbohydrates in their haemolymph. 2. 2. Trehalose in all terrestrial arthropods and primitive insects analysed was either absent or present in very small amounts. 3. 3.

Nucleating agents in the haemolymph of insects tolerant to freezing

Nature, 1976
MANY insects that survive the winter in cold, exposed habitats in arctic or temperate regions are sensitive to freezing. These insects usually have supercooling points below −15°C, and their capacity for supercooling has been shown to increase considerably with increasing concentrations of glycerol in their body fluid1. On the other hand, adult insects

The Composition of Haemolymph in Aquatic Insects

Journal of Experimental Biology, 1962
ABSTRACT Analyses were made of haemolymph obtained from aquatic representatives of nine major orders in the Insecta. In the Odonata, Plecoptera, Ephemeroptera and Hemiptera-Heteroptera, the sodium concentration is relatively high and the potassium concentration is low.

Changes in Haemolymph Proteins in First Instar Locusts

Archives Internationales de Physiologie et de Biochimie, 1966
A number of studies have recently shown that the hacmolymph proteins of Insects change during development. Most of the work in this field has however been done on holometabolous Insects, while only a few studies have been made on the Hemimetabola (STEINHAUER and STEPHEN, 1959 on Periplanefa ; MISSELIJN, KARCHER, DE KEYSER, and VAN SANDE, 1959 on ...

The Separation of Insect Haemolymph Proteins

The Canadian Entomologist, 1964
It has been suggested that information on the phylogenetic relationships of genera and species could be obtained by comparing the amino acid sequence in the homologous proteins of different species. This procedure is extremely difficult and time-consuming.However, a relatively rapid characterization of proteins can be obtained by analysing their ...
