Looming detection by identified visual interneurons during larval development of the locust Locusta migratoria.
Insect larvae clearly react to visual stimuli, but the ability of any visual neuron in a newly hatched insect to respond selectively to particular stimuli has not been directly tested. We characterised a pair of neurons in locust larvae that have been extensively studied in adults, where they are known to respond selectively to objects approaching on a collision course: the lobula giant motion ...
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...
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 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...
