Crop pest management involves killing vast numbers of invertebrates; integrated pest management reduces this mortality while maintaining crop protection through less harmful means.
Crop pest management involves killing invertebrates at a scale that dwarfs all other human-caused animal mortality combined. Even if individual invertebrate welfare significance is low, the precautionary case for reducing unnecessary killing is strong given uncertainty about invertebrate experience. Beyond uncertainty arguments, pesticides routinely kill non-pest species including beneficial insects, pollinators, and soil invertebrates that are clearly welfare-significant. Integrated pest management that uses biological control, threshold-based intervention, and targeted rather than prophylactic chemistry dramatically reduces total invertebrate mortality while maintaining agricultural productivity.
