AP®︎ Environmental Science: Topic 5.14 Flashcards

Combines biological, cultural, physical, and limited chemical methods to keep pests below damaging levels while reducing environmental and human-health risks; it can require greater cost, labor, knowledge, and coordination

An organism whose population damages a valued resource or causes unacceptable agricultural, economic, or health-related harm

Identify the pest, monitor its population and damage, compare it with a threshold, combine appropriate controls, and evaluate and adjust the results

Regularly inspecting, counting, trapping, and recording pests, damage, and beneficial organisms to determine whether control is needed and effective

The pest-population or expected-damage level at which control measures should be applied, set below the economic injury level

The pest level at which the economic value of crop damage equals or exceeds the cost of controlling the pest

The use of living predators, parasitoids, pathogens, or herbivores to reduce a pest population

Changing how crops or managed landscapes are arranged or maintained to hinder pest survival, reproduction, or spread

Changing the crop grown in a field between seasons or years to interrupt the life cycles of pests dependent on a particular host

Growing two or more crops together in the same field to reduce host concentration, hinder pest spread, or support natural enemies

Using barriers, traps, hand removal, machinery, or destruction of infested material to block, capture, remove, or kill pests without relying primarily on toxic chemicals

Selective, targeted pesticide use only when monitoring shows it is needed, using the lowest effective amount while limiting harm to non-target organisms
