Life cycle of the Australian Plague Locust From Department of Agriculture, Fisheries and Forestry, Australian Government In CCA, the unique generation develops in spring and summer, from egg hatching (in early spring) to last egg-laying and death of adults, in late summer. As hoppers, they migrate only a few kilometres each day, basking in the early morning sun until their body temperature rises to a level which allows them to move off and eat all the vegetation in their path. Sixty countries in Asia and Africa are threatened by swarms of the desert locust. Rain causes vegetation growth and spurs the development of eggs that have been laid in the sandy soil. A Desert Locust lives a total of about three to five months although this is extremely variable and depends mostly on weather and ecological conditions. Copulation takes place when a mature male hops onto the back of a mature female and grips her body with his legs. For example, the Locusta migratoria known as migratory locust is found in grasslands of Africa, South Europe, Australia and New Zealand. Solitary (top) and gregarious (bottom) desert locust nymphs After 10 days to two weeks of egg-laying, the eggs hatch and nymphs come out. Ethiopia: Desert Locusts drive one million to food insecurity. She pushes her abdomen down into the sand, extending the membranes between the segments, and burrowing to a depth of 50 or 60 mm. A big group of locusts is called the plague of locusts. Life cycle. The range of the adult locusts is so great that international cooperation is essential for effective control. Figure 2: The desert locust life cycle, solitary and gregarious; graphic courtesy of the Northern Rangelands Trust, Kenya (link to document). If the region of egg-laying is known, the vegetation in the area can be sprayed with an insecticide which kills the hoppers at their first meal. Locusts are found all over the world and look very similar to grasshopper insects. With each three-month generation, there’s a 20-fold increase in locust numbers.

Though all locusts go through the phases, the amount of time spent in each stage varies according to … The … After mating, the female lays her eggs in warm, moist sand following a rainy spell. The desert locust complete its life cycle in three developmental stages viz., Egg, Nymph and Adult (Fig. Eggs. There are also structural differences from the solitary form. Locust at this stage will be having fully-fledged wings that are now fully developed and they will be capable of flying anywhere. It takes 2 weeks for fledglings to fully develop into an adult, we can say that now at this stage it is sexually mature. The life cycle of the desert locust consists of three stages, the egg, the larva known as a hopper and the winged adult. If, however, the hoppers are crowded together for one reason or another, they enter a gregarious phase of activity. However, the nymphs (also known as hoppers) do not have wings and become adults 30-40 days after hatching. Very often the locusts are mistaken for grasshoppers. The life expectancy of typical adult locust is around 10 weeks. Fledgelings also consume large amounts of plants in order to conserve energy for reproduction and wing development. In this burrow, 50 to 100 eggs are laid and mixed with a frothy fluid, which hardens slightly and may help to maintain an air supply round the eggs. The life cycle of the desert locust consists of three stages: egg, hopper and adult and duration of the life is 2-6 months on an average. Such a swarm will consume some 3000 tonnes of vegetation per day; and so if a swarm lands on agricultural crops, the locusts will strip them of every vestige of leaf and edible stem. The desert locust (Schistocerca gregaria) is a species of locust.Plagues of desert locusts threaten agricultural production in Africa, the Middle East, and Asia.They have done so for centuries. Our crops and vegetation form food supply for Desert Locusts. This even as information from different scientists revealed that countries in the Horn of Africa had let the cusp of opportunity—which is the stage before wingless nymphs turn into adult locusts—when it is most logical to spray, escape.
