Aerobic metabolism of the muscle of Locusta migratoria

The characteristics of hexokinase from Locusta migratoria muscle.

Innervation of the ventral diaphragm of the locust (Locusta migratoria).

1. Innervation and some electrical properties of the locust ventral diaphragm were investigated with electrophysiological and histological methods. 2. Muscle fibres are coupled electrically. Electrical stimulation evokes a graded active membrane response. 3. Each segment is innervated by four motor neurones as follows. Two motor neurones are situated in each abdominal ganglion. Branches of thei...

Nitrogenous constituents of the thoracic muscle of the African migratory locust (Locusta migratoria migratorioides).

when expressed as a percentage of the total nitrogen. This observation is in agreement with those recorded previously for typical storage organs. 3. The two plants contained very large amounts of the imino acid, azetidine-2-carboxylic acid. Nitrogen present in azetidine-2-carboxylic acid represented more than 50% of the total nitrogen of Polygonatum rhizome. The imino acid was also present in h...

Evidence for the hormonal function of a CRF-related diuretic peptide (Locusta-DP) in Locusta migratoria

Locusta-DP is a corticotropin-releasing factor (CRF)-related diuretic peptide isolated from the migratory locust Locusta migratoria. At nanomolar concentrations, synthetic Locusta-DP stimulated fluid secretion and cyclic AMP production by Malpighian tubules isolated in vitro and increased the rate of amaranth clearance in starved locusts to levels comparable with those observed during post-feed...

Effect of Ecdysterone on Food Intake of Locusta migratoria Hoppers

Insect growth and developm ent are controlled by hormones [1, 2], The horm ones were also shown to control food intake and utilization in som e insects [3-8]. Ecdysone is associated not only w ith m oult­ ing and m etam orphosis but also with processes preparatory to a moult, such as cessation o f feeding and the onset o f the w andering stage [9]. Recently evidence for a relationship between f...
