Serotonin mediates behavioral gregarization underlying swarm formation in desert locusts.
Desert locusts, Schistocerca gregaria, show extreme phenotypic plasticity, transforming between a little-seen solitarious phase and the notorious swarming gregarious phase depending on population density. An essential tipping point in the process of swarm formation is the initial switch from strong mutual aversion in solitarious locusts to coherent group formation and greater activity in gregar...
متن کاملA Conceptual Framework for Economic Evaluation of Desert Locust Management Interventions
The difficulty lies not in new ideas, but in escaping from old ones. Preface The desert locust is an ancient problem. People in Africa, the Middle East and parts of Asia had to live and cope with it for many centuries. It is only with the development of chemical pesticides that man developed the belief he could solve this problem by adopting a strategy of war against nature. Spraying poisonous ...
متن کاملPreventing desert locust plagues: optimizing management interventions
Solitarious desert locusts, Schistocerca gregaria (Forskål) (Orthoptera: Acrididae), inhabit the central, arid, and semi-arid parts of the species’ invasion area in Africa, the Middle East, and South-West Asia. Their annual migration circuit takes them downwind to breed sequentially where winter, spring, and summer rains fall. In many years, sparse and erratic seasonal rains support phase chang...
متن کاملAssaying Visual Memory in the Desert Locust
The involvement of associative learning cues has been demonstrated in several stages of feeding and food selection. Short neuropeptide F (sNPF), an insect neuropeptide whose effects on feeding behavior have previously been well established, may be one of the factors bridging feeding and learning behavior. Recently, it was shown in Drosophila melanogaster that the targeted reduction of Drome-sNP...
متن کاملField Verification of the Prediction Model on Desert Locust Adult Phase Status From Density and Vegetation
Previous studies investigated the effect of vegetation on density thresholds of adult Desert Locust gregarization from historical data in Mauritania. We examine here the prediction of locust phase based on adult density and vegetation conditions using the statistical model from Cisse et al. compared with actual behavior of Desert Locust adults observed in the field in Mauritania. From the 130 s...
