“…The satellite data made possible the early mitigation of plagues, thus preserving large crop areas that would have otherwise been lost. Locusts cannot be identified directly with satellite images for they are very tiny, so previous studies took an indirect approach by monitoring the key environment factors that influence plague outbreak such as rainfall, vegetation type and vegetation cover and so on (Hielkema, 1981;Hamilton and Bryceson, 1993;McCulloch and Hunter, 1983;Ni et al, 1999;Bryceson, 1989;Voss and Dreiser, 1997;Ji et al, 2004;Tratalos and Cheke, 2006;Sivanpillai et al, 2006). Among the environment factors that affect locust plagues, soil moisture influences the locust egg laying site location and the survival of locust eggs through the winter, as well as egg-hatching rate.…”

“…Since, like in the case of the desert locust, the breeding zones of the Australian plague locust are situated in remote and semidesert locations, the Australian entomologists were among the first to use satellite data for locust habitat mapping since the early 1980s. 46,72,73 These studies showed that satellite data were instrumental in detecting the emerging vegetation and changes in vegetation condition which could then be associated with locust breeding areas, particularly the egg-bed locations. 74 As such, it was possible to locate the areas which served as sources of locust outbreaks.…”

“…The first applications of remote sensing to locust monitoring were attempted as early as the 1970s to 1980s in Africa 44,45 and Australia. 46 Since then, there is a substantial body of publications on the subject (see Ref. 47 for review and references therein).…”

“…After the pioneer studies by Pedgley 44 and Hielkema, 45,64 remote sensing has been used for finding and mapping emerging vegetation in the desert to help monitor and forecast the desert locust 50,56,66,68,69 and the Australian plague locust. 46,49,51,[72][73][74][75][76][77][78][79][80][81][82] The tool allows assessing the ecological conditions favorable for locust survival, breeding, and gregarization. Identification of areas with emerging green vegetation helps in rapid decision-making regarding control interventions against the initial locust congregations.…”

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 10% of the world's population. The locusts are infamous for their voracity, polyphagy, and capacity for long-distance migrations. Decades of research revealed very complex bioecology of locusts. They exist in two, inter-convertible and density-dependent states, or "phases." Despite the evident progress in understanding locust behavior, our ability to predict and manage locust outbreaks remains insufficient, as evidenced by locust plagues still occurring during the 21st century. One of the main reasons is that locusts typically inhabit remote and scarcely populated areas, and their distribution ranges often spread across continents. This creates tremendous obstacles for locust population monitoring and control. Traditional ground locust surveys are inadequate to address the enormous spatial scale of the locust problem in a limited window of time dictated by the pest's development. Remote sensing (satellite information) appears a promising tool in locust monitoring. Satellite data are increasingly used for monitoring and forecasting two locust species, the desert and the Australian plague locust. However, applications of this geospatial technology to other locust species remain rare. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.

“…In this area, locusts are most common in open clay plains and stony downs (McCulloch & Hunter 1983). Rainfall of about 40 mm is required for significant growth of curly Mitchell grass {Astrebla lappacea [Lindl.]…”

Stony downs consist of grassy areas that alternate with areas that have a substantial stone cover. The stone-covered areas are impermeable, and most rain falling on them runs off, substantially increasing the effective rainfall in adjacent grassy areas. As a result, 20-25 mm of rain on stony downs wetted the soil around the grass to a depth of 140-170 mm and allowed sustained grass response. This is much less than the 35-40 mm of rain required for the same response on red clay or grey clay plains.Grasses respond very rapidly after rain. Some have green shoots the day after rain, and all have responded by the second day. Ephemerals dry off in 4-6 weeks, but most tussock grasses still have some green foliage 8-10 weeks after rain. Deeper rooted tussock grasses remain green for so long because most of the moisture that reaches deeper roots after rain remains there. Most moisture loss is through the soil surface and is recognizable as a drying front that descends through the soil profile. Soil above the drying front is nearly air dry (<5% moisture) while soil below the front has substantial moisture (14-16%). By about a month after rain in summer, the drying front is at a depth of about 80-120 mm. This is near the tips of the roots of ephemeral grasses and the ephemerals then dry off rapidly. Only the tips of the leaves of deep rooted grasses like Mitchell grass (Astrebla spp.) dry off. Their leaves continue to remain mostly green during most of the second month after rain and they do not dry off completely until the third month when the drying front reaches the bottom of the main root system.
