Oviposition Digging in the Grasshopper
1. Transection of the ventral nerve cord of female grasshoppers activates the rhythmical motor programme for oviposition digging. 2. Electrical stimulation of the cut nerve cord had the following effects on elicited oviposition motor activity: (i) shortand long-lasting inhibition of activity, (ii) phase resetting and (iii) modulation of burst frequency. 3. Cold saline applied to the nerve cord ...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولAn analysis of a circadian rhythm of oviposition in Oncopeltus fasciatus.
Several behavioural circadian rhythms have been described in Oncopeltus fasciatus, including daily cycles of mating, feeding, oviposition, flight, and general locomotor activity (Caldwell & Dingle, 1967; Dingle, 1968; Caldwell & Rankin, 1971). This insect is known to be migrant, and the temporal segregation of daily activities brought about by this temporal organization is adaptive in relation ...
متن کاملDopaminergic modulation of phase reversal in desert locusts
Phenotypic plasticity allows animals to modify their behavior, physiology, and morphology to adapt to environmental change. The global pest, the desert locust, shows two extreme phenotypes; a solitarious phase that is relatively harmless and a gregarious phase that forms swarms and causes extensive agricultural and economic damage. In the field, environmental conditions can drive isolated anima...
متن کاملOviposition digging in the grasshopper. I. Functional anatomy and the motor programme.
The ovipositor appendages of acridid insects (grasshoppers and locusts) consist of two pairs of shovel-shaped valves that are used to dig a deep chamber in the ground for egg burial, to manipulate the eggs, and to assist in capping the egg-pod with froth. During oviposition the valves undergo cyclical opening, closing, retraction and protraction movements. These movements are produced by the co...
