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 change and local outbreaks at only a few sites. Less frequently, seasonal rains are widespread, frequent… 
Importance of solitarious desert locust population dynamics: lessons from historical survey data in Algeria
The study confirmed the importance of migrations of solitarious populations among Algerian regions and more generally within the recession area of this species and confirmed the necessity for the inclusion of wadis and soil moisture estimations from remote sensing in geographic information systems for preventive management.
Locust and Grasshopper Outbreaks in the Near East: Review under Global Warming Context
Plagues of locust possibly date back to before humanity, as they evolved before humans. Following the Neolithic revolution and the permanent settlement of humans in Mesopotamia, locusts and
Early Intervention against Desert Locusts: Current Proactive Approach and the Prospect of Sustainable Outbreak Prevention
Salient needs presently include long residual tactics for prophylactic (preventive) control in breeding areas, intervention thresholds, and improved, sustainable coordination among stakeholders at national, regional, and international levels.
A monitoring system for preventive control of Desert Locust in West Africa
Agricultural pests like the Desert locust, Schistocerca gregaria (Forskal 1775), often migrate across borders and cause major losses and emergencies. In the past, such damage often led to famines and
Plagues of Desert Locust: No invasion risk to China
The risk that the desert locust will invade China is very low, and areas of potentially suitable habitat within China based on historical precipitation and temperature data are identified, which found that parts of Xinjiang and Inner Mongolia provinces could provide ephemeral habitat in summer, but these places are remote from any other desert locUST breeding area.
Locusts and remote sensing: a review
Abstract A dozen species of locusts (Orthoptera: Acrididae) are a major threat to food security worldwide. Their outbreaks occur on every continent except Antarctica, threatening the livelihood of
Dynamic Simulation Model of Central American Locust Schistocerca piceifrons (Orthoptera: Acrididae)
A dynamic model of locust growth and development as a function of environmental conditions is proposed for use as a tool to support S. piceifrons monitoring by the National Locust Control Program.
Dynamic Simulation Model of Central American Locust Schistocerca piceifrons (Orthoptera: Acrididae)
A dynamic model of locust growth and development as a function of environmental conditions is built in order to identify suitable conditions for the high reproduction rates of this insect.
A Global Review on Locusts (Orthoptera: Acrididae) and Their Interactions With Livestock Grazing Practices
Connections between locusts and people date back millennia and locusts remain a major food security challenge today throughout the world. Locust biology is often linked to abiotic conditions like


African armyworm outbreaks: why do they occur after drought?
The existence of a delayed indirect effect of drought on outbreak development of the African armyworm is postulated, based on the knowledge that the decomposition of organic material by bacteria in a soil after wetting is correlated with the duration and temperature of the drying period to which the soil has been exposed.
Habitats and spatial pattern of solitarious desert locusts (Schistocerca gregaria Forsk.) on the coastal plain of Sudan
The spatial distribution of the desert locust on the southern part of the Red Sea coastal plain of Sudan, between Port Sudan and Tokar, was investigated to determine habitat associations of the Desert locust and collect information that might help in planning survey and control operations.
Spread of a migratory locust plague in Madagascar
Since 1997, Madagascar has been experiencing an outbreak of the Migratory Locust that is the most severe for about fifty years. In spite of vast control operations, both terrestrial and by air, over
Development of a desert locust plague
The subject at issue in the population dynamics of the desert locust is whether plagues originate from an upsurge in numbers and associated transformation from the solitary-living to the gregarious state, or from successful breeding by g Regarious populations postulated to survive continuously throughout the interplague recession periods.
The development and termination of the 1968 plague of the desert locust, Schistocerca gregaria (Forskål) (Orthoptera, Acrididae)
The most economical strategy for plague prevention might be one of upsurge elimination, that is to say control in selected areas against gregarious locusts only, and the implications of adopting such a strategy are discussed.
Outbreaks and recession populations of the desert locust Schistocerca gregaria (Forsk.)
It is shown that the hopper bands and swarms reported during the 1963–67 recession differed qualitatively and quantitatively from those characteristic of plague periods and were numerically much smaller than some low density non-swarming populations.
The Outbreak Centres of Schistocerca gregaria , Forsk., on the Red Sea Coast of the Sudan
The results of the investigations on the Red Sea coast put under suspicion of harbouring outbreak areas of the Desert locust all those parts of the sea-coasts of Africa and Asia which may obtain in some years winter rainfall of not less than 240 mm.
Effects of Changing Land Use on Outbreaks of Tropical Migratory Locust, Locusta Migratoria Migratorioides (R. & F.)
Continuous agricultural development in tropical and sub-tropical areas of the Old World will bring the risk of further upsurges of tropical migratory locust numbers through agricultural and pastoral activities.
Recent progress in Desert and Migratory Locust management in Africa. Are preventative actions possible ?
A realistic solution to prevent locust plagues requires stronger commitment of governments and donors, sustainable small but flexible national locust control units for prevention, and especially the creation of emergency action plans, ready to quickly mobilize and organize complementary resources in the event of an upsurge.
Characteristics of Desert Locust plague upsurges
Between plagues, the Desert Locust typically exists in low-density populations which migrate between successive breeding areas in its extensive and arid recession area, and requires adequate monitoring and control of populations in the breeding areas.
