Global Locust Initiative Lab
The Global Locust Initiative Lab is centered at Arizona State University and leverages state of the art locust rearing facilities and laboratory space. In collaboration with an interdisciplinary team, members of GLI Lab conduct projects on multiple continents to study nutritional ecophysiology, land-use practices, and governance, with a goal of advancing both fundamental research and sustainable solutions to meet the challenge of locust and grasshopper outbreaks.

2020–2025

Transforming the study of phenotypic plasticity
Project Overview
Behavioral Plasticity Research Institute (BPRI) is an interdisciplinary and cross-organizational virtual institute funded by the National Science Foundation and led by the Baylor College of Medicine. It uses locust phase polyphenism as a model system to revolutionize the investigation of phenotypic plasticity. The research connects suborganismal processes to the organism and their environment to address complex issues like outbreaks, collective movement, and mass migration. The ASU team is leading efforts to compare and contrast nutrient regulation in the six Schistocerca species and integrate ecological factors into the study of phenotypic plasticity.

Interdisciplinary lab and field research on locust migration, immune function, and reproduction.
Project Overview
The CAREER project focuses on how nutrition, population density, and historical habitat variability interact to affect migration, immune function, and reproduction of locusts. It integrates lab and field research to form an interdisciplinary approach to advance our understanding of why and how animals migrate and increase our ability to predict migratory responses to global change.

New Innovator in Food and Agriculture Research Award
Addressing barriers to integrating research and adoption of sustainable practices for managing locusts in Senegal, South America, and Australia.
Project Overview
Co-sponsored by the Foundation for Food and Agriculture Research (FFAR) and Arizona State University (ASU), also with support from ASU’s Swette Center for Sustainable Food Systems, this project addresses challenges and opportunities in managing and researching grasshopper and locust pests. It spans from biological research identifying land use practices that suppress locust populations to comparing governance structures for how different regions around the world manage locusts, to create common global resources for stakeholders.

Monitoring and Soil Amendments for Locust and Grasshopper Management
A Pilot Project in the Kaffrine Region of Senegal
Project Overview
The Senegalese Grasshopper (Oedaleus senegalensis) is among the most severe pests of the Sahel. This species regularly attacks staple cereal crops which, combined with low soil fertility, reduces farmers’ resiliency and food security. This project pilot introduced a sustainable methodology for locust management in the Kaffrine Region of Senegal: the use of locust biology to reduce crop damage. By leveraging research that illustrates strong soil-plant- locust interactions, this project proposes a novel long-term and community-based preventative strategy: setting up village-based soil amendment and locust monitoring programs to create environments unfavorable to locusts.

Testing macronutrient imbalance as a key factor limiting range expansion in herbivores
Project Overview
The South American Locust (Schistocerca cancellata) is experiencing the greatest population upsurge in 60 years. In 2017, large swarms left their small permanent breeding zone in NW Argentina and invaded Bolivia and Paraguay, and expanded throughout Argentina. The RAPID grant allowed researchers to collect time-sensitive data on locust macronutrient balancing in the field, which has emerged as a key factor in regulating insect behavior, physiology, and performance. We tested the hypothesis that S. cancellata in their expansion zones are unable to obtain food of sufficiently high carbohydrate:protein ratio to maximize their fitness.

Grasshopper Rearing in Support of Methods Development for Rangeland Research
Project Overview
The primary goal of this cooperative agreement between the USDA and Arizona State University is to better support critical laboratory experiments with insecticides outside of the summer field season and further Rangeland Unit’s mission of developing novel management methods while improving existing ones for grasshoppers and Mormon crickets in the rangelands of the seventeen contiguous western states.

2013 – 2019

Linking Livestock Markets and Grazing Practices with the Nutritional Ecology of Grasses and Locusts Under Alternative Property Rights Regimes
Project Overview
This project integrated novel fundamental research from multiple disciplines across four different countries —Australia, China, Senegal, and the US—to improve our ability to manage social-ecological systems. We investigated physiological, ecological, and nutritional mechanisms responsible for locust outbreaks and migration. This is one of the first projects to apply both highly-controlled lab and field-based techniques to connect physiological mechanisms to agricultural practices and livelihoods.
