“…S. p. piceifrons appears to use the patchily distributed shrub Pisonia aculeate for refuge, as the plant remains green yearround. This plant potentially drives aggregation by concentrating locust densities (Poot-Pech et al, 2016;Cullen et al, 2017). Research on the environmental drivers of locust density in the Yucatán peninsula demonstrated a correlation between locust density and the presence of the grass Panicum maximum, but no correlation with soil type (Poot-Pech et al, 2018).…”

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 temperature and/or precipitation, fueling the perception that aside from active control, humans are not key players in the interaction locusts have with their environment. However, several studies have shown that land management practices like grazing heavily influences locust-human linkages. In this review we synthesize published research and reports on connections between locust outbreaks and ranching. For this, we conducted an extensive literature search using Google Scholar on the 19 species of grasshoppers that are currently considered to be locusts or non-model locusts. Species were sorted according to their feeding guilds: (1) forb-and/or tree-feeding locusts; (2) mix-feeding locusts (grasses, forbs, and/or trees); (3) grass-feeding locusts. We review their pest status, ecology, and relationship with grazing. We then discuss the overall data and draw general patterns on how locusts and locust control affect livestock grazing through various mechanisms (competition, nutritional preferences, pesticide use, nutrient cycling). We draw attention to "telecoupling" a process in which land management practices like grazing have ecological feedbacks on locust populations, which in turn affects food security in distant regions due to the migratory capacity of locusts. Finally, we present new perspectives for sustainable management practices that integrate understanding of land management.

“…Unlike S. gregaria, S. piceifrons is attracted more generally by odour of any plants that can provide refuge and protection from natural enemies. For example, Pisonia aculeate is a large shrub that attracts S. piceifrons and promotes aggregation because it stays green during the dry season and can be patchily distributed (Poot-Pech et al, 2016).…”

Locusts are grasshoppers (Orthoptera: Acrididae) that are characterised by their capacity for extreme population density-dependent polyphenism, transforming between a cryptic solitarious phase that avoids other locusts, and a swarming gregarious phase that aggregates and undergoes collective migration. The two phases differ in many aspects of behaviour, physiology and ecology, making locusts a useful model through which to investigate the phenotypic interface of molecular processes and environmental cues. This review summarises recent progress in understanding the mechanisms and consequences of locust phase change, from differential gene expression and epigenetic regulation through to neuronal plasticity and altered behaviour. The impact of techniques such as RNA interference (RNAi), and the sequencing of the first locust genome is discussed, and we consider the evidence from comparative analyses between related locust species for the possible evolution of locust-like phenotypic plasticity. Collective movement, and new ways of measuring the behaviour of both migrating bands in the field and individuals in the laboratory, are analysed. We also examine the environmental factors that affect phase change, along with the wider impact of land use and management strategies that may unwittingly create environments conducive to outbreaks. Finally, we consider the human costs of locust swarming behaviour, and use combined social, economic and environmental approaches to suggest potential ways forward for locust monitoring and management.

“…It has been recorded to feed on up to 400 plant species, feeding on both cropped and grazing areas, including dry vegetation [4,9,27,28]. Feeding ecology of the CAL is not fully understood, but a recent study on the effect of plant volatiles and feeding preference of the CAL showed that the CAL in the Yucatán Peninsula was highly attracted to the odor of Pisonia aculeata L., which it uses as a refuge but not for feeding [22]. As for the feeding preference, the study revealed that the CAL showed marked feeding preference for two native plant species, Leucaena glauca Benth and Waltheria americana L. [22].…”

“…During the most recent outbreak in 2018-2020, the National Service of Agri-food Health, Safety and Quality (SENASICA) introduced the potential use of unmanned aerial vehicles (UAVs) or drones for the monitoring of locust populations in addition to land monitoring [20,21]. Currently, several research lines elucidate on the evolution of phase polyphenism, the environmental factors that trigger gregarization and swarm formation, the bioactive compounds and nutritional contents of the CAL, and the improvement of an early warning system (EWS) [8,15,19,[21][22][23][24][25][26]. Hopefully this work will provide novel information and knowledge that helps to improve the management and control strategies of the CAL.…”

State of the Art Management of the Central American Locust Schistocerca piceifrons piceifrons (Walker, 1870)

The Central American locust (CAL), Schistocerca piceifrons piceifrons (Walker, 1870), is a transboundary pest that is distributed from Mexico to Panama. It is a true locust species characterized by density-dependent phase polyphenism. The ancient record of the CAL is found in the Popol Vuh, the Mayan sacred book, demonstrating how it has affected humans for millennia. In Mexico, the CAL have been declared a national threat to agriculture since 1824. Serious locust plagues occurred in 1882–1883 when swarms of 20 km2 in size invaded the Yucatán Peninsula and neighboring states in southern Mexico and, since then, management actions to suppress populations and economic damage have been implemented. A better understanding of the biology, ecology, and behavior of the CAL replaced a manual and mechanical collection of locust swarms, hopper bands, and egg pods with modern techniques such as the use of safer chemical products and environmentally friendly bioinsecticides. Presently, biomodels and GIS support the monitoring and forecasting of outbreaks. Currently, studies are conducted to investigate environmental factors that trigger locust gregarization, the evolution of phase polyphenism, and CAL bioactive compounds and nutritional contents, envisioning its potential use in biotechnological industries. Findings will be crucial to improve the management strategies of the CAL.
