Abstract Although the vast majority of orthopterans are not pests, some species have the potential to cause serious damage to human interests. Management of pest populations frequently conflicts with conservation of orthopteran species and processes, particularly when the pest species or its ecological processes are susceptible to extinction or when the pest population is coincident with non-target orthopterans. With respect to chemical control, the greatest hazards are the broad-spectrum, highly lethal properties of most agents, which can be mitigated with formulation and application methods. Biological control risks permanent, large-scale changes to orthopteran species and processes which can be minimized with bioinsecticidal and other short-lived or selective formulations and reliable host-range testing. Cultural control may have large-scale, broad-spectrum impacts to non-target orthopterans, but these hazards can be diminished by appropriate testing and monitoring. Mechanical control methods may be impractically labour intensive, but they are highly target specific and therefore warrant further consideration. Social control measures such as education, insurance and compensation programmes appear to have little direct potential for harm to orthopteran conservation, but the complex socioeconomic and, ultimately, environmental consequences of such programmes have not been assessed. The melding of orthopteran pest management and conservation requires that we perceive these insects and their ecological processes to be vital elements of sustainable agroecosystems. Our management of orthopterans (both non-target and pest populations) must focus on keeping good stewards on the land.
