Biomagnification - (ANSWER)Accumulation of pollutants at successive levels of
the food chain
abiotic factors - (ANSWER)natural control measures within the environment.
EX: climactic factors, air/water pollution, topographic features.
Biological Control - (ANSWER)The use of natural enemies to control pests.
EX: Predators, Parasites, Pathogens
Cultural Control - (ANSWER)These are Practices that reduce pest establishment,
reproduction, dispersal and survival.
EX: Mowing, irrigation, aeration, fertilization and sanitation.
Genetic control - (ANSWER)Making use of plant varieties that are naturally
resistant to insect feedings.
, Mechanical/Physical control - (ANSWER)Kills a pest directly or makes its

Site of action - (ANSWER)The specific biological system affected within the pest
Economic threshold - (ANSWER)The point at which the economic loss caused by
pest damage outweighs the cost of applying a pesticide.
(Treat pests when they pass the economic threshold)
Economic injury level - (ANSWER)the pest population density that causes losses
equal to the cost of control measures
Action threshold - (ANSWER)the predetermined level at which pest control is
needed
