On insects inhabiting salt water

Dispersal Ecology of Insects Inhabiting Wood-Decaying Fungi

Water and Salt Excretion

Jrntravenous salt-loading tests were performed in 20 hypertensive and 31 normotensive subjects. During the following 5 half-hour collection periods both water and salt excretion by the hypertensive subjects was higher than by the normotensive ones. The diuretic response was much more prolonged and more pronounced than the saluretic response and appears to be a primary response to the salt load,...

Cryoprotectant systems and cold tolerance of insects inhabiting central Yakutia ( Russian Far East )

Strong tolerance of freezing is an important strategy for insects living in extremely cold regions. They produce highly effective cryoprotectant systems consisting of ice-nucleating proteins and polyols, which enables tolerable freezing of the body fl uid. Therefore, the measurement of the concentrations of polyols and the activity of ice nucleators in the haemolymph is an essential tool for de...

Larval antennal sensilla in water-living insects.

An overview of larval antennal sensilla in hemimetabolous and holometabolous water-living insects is given by updating current knowledge on the fine structure of these sensory systems. In the absence of successful electrophysiological studies, the possible function of sensilla is deduced from their architecture. Various kinds of sensilla are described in hemimetabolous insects, such as Ephemero...
