15 صفحه اولEvidence 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...
متن کاملParental crowding influences life-history traits in Locusta migratoria females.
Parental environments could play an important role in controlling insect outbreaks, provided they influence changes in physiological, developmental or behavioural life-history traits related to fluctuations in population density. However, the potential implication of parental influence in density-related changes in life-history traits remains unclear in many insects that exhibit fluctuating pop...
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...
