A pest refers to organisms, primarily insects, that infest crops, livestock, or human habitats, causing economic or health-related harm. Authors like Sir A. E. Shipley highlighted the hidden complexities of pests affecting food supplies, while Albert Smith Bickmore vividly depicted their tangible nuisance in tropical environments.
Horace Fletcher linked pests to psychological responses, and U. P. Hedrick detailed agricultural methods to combat them. From scientific treatises to personal accounts, these works underscore pests as both a persistent challenge and a central focus for human ingenuity in mitigation.
