Preventive control and Desert Locust plagues

open access: yesCrop Protection, 2008
The original locust control strategy assumed that plagues arose when swarms escaped from outbreak areas and bred successfully in the surrounding invasion area. Thus, control within outbreak areas could prevent plagues. Plague prevention was achieved for species with small, relatively accessible outbreak areas providing resources allocated to preventive

The Desert Locust

JAMA: The Journal of the American Medical Association, 1972
Sometimes useful collaborators, sometimes implacable enemies, the insects may eventually conquer man in the war for survival. One of the great threats to mankind is the desert locust, whose swarms devastate huge areas of vegetation and bring near-starvation to millions.

Density–dependent aposematism in the desert locust

open access: yesProceedings of the Royal Society B: Biological Sciences, 2000
The ecological processes underlying locust swarm formation are poorly understood. Locust species exhibit phenotypic plasticity in numerous morphological, physiological and behavioural traits as their population density increases. These density-dependent changes are commonly assumed to be adaptations for migration under heterogeneous environmental ...

Soil moisture from remote sensing to forecast desert locust presence

open access: yesJournal of Applied Ecology, 2019
Preventive control of desert locusts is based on monitoring recession areas to detect outbreaks. Remote sensing has been increasingly used in the preventive control strategy.

Bracken and Locust Ecdysones: Their Effects on Molting in the Desert Locust

Science, 1968
Bracken contains ecdysone derivatives that are active when injected into locusts. However, when fed to the desert locust as its sole or chief diet, it does not affect molting, growth, or development. There is evidence that, in locusts, the active ecdysones are dehydroxylated to α-ecdysone and passed out through the gut in the feces.

Desert locust plagues

Endeavour, 1995
Abstract Some 3000 years ago the prophet Joel listed four great plagues afflicting his people: the locust, the cankerworm, the caterpillar and the palmerworm. Despite great advances in both chemical and biological methods of control, the Desert Locust still periodically wreaks havoc over large areas. Apart from the intrinsic difficulty of the problem,

Development of a desert locust plague

Nature, 1975
THE role of phase change in the development of plagues of the desert locust, Schistocerca gregaria (Forskal), has been debated for many years1–5. Much confusion has arisen because changes in behaviour, form and colour, which have all been used as indicators of phase status, do not proceed at the same rates.

Desert Locusts in Africa: a Disaster?

Disasters, 1995
Migrating locusts, especially the desert locust (Schistocerca gregaria), have been feared in Africa for thousands of years as famine‐inducing pests. Instead of simply waiting for outbreaks to occur, attempts are being made to take preventive action against these pests.

A GIS for desert locust forecasting and monitoring

International Journal of Geographical Information Systems, 1996
Desert locust plagues can affect up to 20 per cent of the surface of the Earth. Data on locust breeding, environmental conditions and swarm movements in affected countries, are collected at the headquarters of the U.N. Food and Agriculture Organization in Rome.
