Small sized ribosomes from mitochondria of locusta migratoria.
RNA species from locust flight muscle mitochondria with apparent molecular weights of about 0.5 and 0.2 X lo6 have been reported [l-3]. In this paper data are presented which establish the existence of particles in locust muscle mitochondria having essential properties in common with ribosomes from which these RNA species may be derived. The sedimentation constant of these particles was estimat...
متن کاملInvestigation of the histological development of the frontal ganglion in Locusta migratoria L. 1758 (Orthoptera, Acrididae)
Th e frontal ganglion plays a critical role in insect feeding and molting-related behaviors. It is present in all insect orders at all developmental stages. In this study, the histological development of the frontal ganglion of Locusta migratoria, the African migratory locust, was investigated. Ganglia were dissected at 3 distinct developmental stages and their histological structure was evalua...
متن کاملInnervation 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...
متن کاملEffect 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...
متن کاملEvidence 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...
