Region:Americas
Subregion:Northern America

There are more than 400 known species of grasshoppers in the United States. Only about a dozen of these species are considered important pests on rangelands and many are beneficial members of ecosystem communities. [1]

Periodic outbreaks of pest grasshopper species do affect farmers and ranchers, particularly in the western regions of the United States.[2] Since 1920, annual surveys have been conducted to monitor and address these cyclical grasshopper infestations.[3] Grasshopper outbreaks can have significant economic consequences for agriculture in the United States. They can cause substantial crop losses, reduce forage availability for livestock, and increase production costs for farmers due to the need for pest control measures or to replace forage with hay. The economic impact varies from year to year and from region to region, depending on grasshopper population levels.

Among the 400 grasshopper species inhabiting the western United States and Canadian prairies, only around two dozen species are responsible for economically significant crop damage on an annual basis. [4] [5] [6][2] Among these species, the migratory grasshopper, Melanoplus sanguinipes stands out as the most destructive pest in the United States and certain southern regions of Canadian grasslands. [5] [6] Other important species include[2]:

Grasshopper infestations had a profound impact during the 1930s and mid-1980s, with the 1930s outbreaks being instrumental in the establishment of a USDA program mandated by Congress to effectively manage such outbreaks. This program, known as the Animal and Plant Health Inspection Service (APHIS) Rangeland Grasshopper and Mormon Cricket Suppression Program, works in conjunction with the USDA's Agricultural Research Service (ARS) to continually enhance management techniques.[2] Collaborations extend to multiple university research groups, as well as various federal entities like the Bureau of Land Management (BLM), state departments of agriculture, tribal councils, and private stakeholders such as ranchers providing land for experimental purposes.[7]

While there are no locusts in the United States today, the Rocky Mountain locust, Melanoplus spretus (Walsh, 1866), once swarmed the Great Plains of North America. Prior to 1900, it was the most significant pest of its kind, aggregating in unprecedented numbers, making it the record holder for the largest documented swarms among all locust species worldwide. [8] [9] The inception of the U.S. Department of Agriculture's (USDA) emphasis on combating insect pests can be traced back to the Rocky Mountain locust.[10] The presumed last specimens of this species were discovered in Canada in 1902, and in 2014, the International Union for Conservation of Nature (IUCN) officially declared the species extinct.[11]

To address locust plagues beyond the borders of the United States, United States Agency for International Development (USAID) plays a role by providing support, predominantly through funding efforts and research. [2]

Organizational relationships

In the United States, best practices for grasshopper management are commonly shared through bulletins, handouts, websites, and other publications, primarily at the federal and state levels.[2] The aim is to provide relevant and valuable information to stakeholders, enabling them to protect agricultural interests from the economic impacts of grasshopper outbreaks. In the past, localized management efforts for grasshopper control often failed due to the mobile nature of the threat.[7] As a result, the United States recognized the need to address the issue at the federal level and foster collaboration among partners from diverse backgrounds. [7] [10]

Funding from the federal government often supports various research initiatives undertaken by collaborating partners.[2] A notable example is the Grasshopper Integrated Pest Management (IPM) Project initiated by USDA-APHIS in 1987, which remains the largest collaborative project in the United States. Valuable knowledge gained from this project was compiled and shared with the public in the form of the Grasshopper Integrated Pest Management User Handbook (1996-2000). The project fostered enduring relationships with universities and continues to establish new partnerships, all working towards the same overarching goal.[2]

The knowledge and expertise gained from U.S. locust management efforts have been shared internationally through collaborative ventures.[2] Collaborative projects with countries like Canada, focusing on population forecasting, Mexico's ongoing project centered on modeling the potential migration of the Central American locust (Schistocerca piceifrons). Additionally, distant collaborations have occurred, such as with Australia, where members of APHIS were invited by the Australian Plague Locust Commission (APLC) in the 1990s for reciprocal information exchange.[2]

University extension programs also play a role in managing pest grasshoppers in the US. Extension programs often conduct research to understand the behavior, biology, and ecology of grasshoppers which can help inform management decisions. Extension officers spend a lot of time on education and outreach efforts to disseminate information to farmers, ranchers, and the wider community. Extension programs are often effective at fostering collaborations with various stakeholders, including government agencies and industry partners.

Regional management strengths and challenges

Strengths

The grasshopper management structure in the United States benefits from the availability of high-quality datasets encompassing sociodemographic variables.[2] This enables comprehensive studies on the impacts of locust outbreaks and pest control measures. Additionally, the preservation of historical knowledge in numerous publications contributes to a rich understanding of pest grasshoppers. Furthermore, the commitment of the federal government to allocate a congressional budget line for ongoing management research, annual population surveys, and treatments is a significant advantage that ensures a sustained effort in combating grasshopper issues. [2]

Another key strength lies in the ability to foster collaboration among stakeholders from diverse backgrounds across the nation. [2] This collective effort enables the investigation of improved, cost-effective, and sustainable management methods. Such collaborations have led to innovative advancements in technology and chemistry, resulting in more efficient population suppression both before and during outbreaks.

For instance, the utilization of diflubenzuron, an insect growth regulator insecticide, has proven effective in inhibiting proper molting during non-adult instar stages.[12] Additionally, the adoption of reduced agent and area treatments (RAATs) has shown promise. This approach involves alternating insecticide treatments with untreated areas of habitat, thereby minimizing environmental impact and reducing costs.[13] These advancements demonstrate the ongoing efforts to develop environmentally conscious and cost-effective strategies for grasshopper management.

Challenges

There has been a decline in the number of researchers dedicated to studying grasshoppers and their IPM. This decline seems to align with a reduced perception of grasshoppers as a significant threat, likely due to less frequent outbreaks, which can be attributed to improved management practices. However, it should be noted that high-density grasshopper populations and periodic outbreaks still pose challenges for many ranchers and farmers, despite the shifting perception.[2]

Another weakness lies in the decreasing funding, both from federal and other sources, which may be influenced by the aforementioned perception changes. This decrease in funding has a direct impact on available personnel for conducting annual federal surveys on population levels and treatments, potentially exacerbating the decline in grasshopper researchers.[2] There is also a challenge in sharing data archives between federal and non-federal researchers due to concerns about sharing private information regarding stakeholders associated with outbreaks, which hinders the seamless exchange of valuable information.

Overall, these weaknesses highlight the need for continued support, investment, and collaboration to address grasshopper management effectively and overcome the associated challenges.[2]
