detailed answers ||
Bioaccumulation - ✔✔The accumulation of a substance, such as a toxic chemical, in || || || || || || || || || || || || ||
various tissues of a living organism.
|| || || || ||
Biomagnification - ✔✔Accumulation of pollutants at successive levels of the food chain
|| || || || || || || || || || ||
abiotic factors - ✔✔natural control measures within the environment.
|| || || || || || || ||
EX: climactic factors, air/water pollution, topographic features.
|| || || || || ||
Biological Control - ✔✔The use of natural enemies to control pests.
|| || || || || || || || || ||
EX: Predators, Parasites, Pathogens
|| || ||
Cultural Control - ✔✔These are Practices that reduce pest establishment, reproduction,
|| || || || || || || || || || ||
dispersal and survival. || ||
EX: Mowing, irrigation, aeration, fertilization and sanitation.
|| || || || || ||
Genetic control - ✔✔Making use of plant varieties that are naturally resistant to insect
|| || || || || || || || || || || || || ||
feedings.
Mechanical/Physical control - ✔✔Kills a pest directly or makes its environment unsuitable || || || || || || || || || || ||
EX: Rodent traps, deer fences, mulches, barriers
|| || || || || ||
Regulatory control - ✔✔Removal of pests that cant be controlled at a local level. Utilizes
|| || || || || || || || || || || || || || ||
quarantines to prevent entry of pests at airports or ocean ports and can be used to remove
|| || || || || || || || || || || || || || || || ||
, 2
pests with government power. (i.e. draining standing water that provides breeding sites for
|| || || || || || || || || || || || ||
mosquitos.)
Mode of action - ✔✔How chemicals kill a pest
|| || || || || || || ||
Site of action - ✔✔The specific biological system affected within the pest
|| || || || || || || || || || ||
Economic threshold - ✔✔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 - ✔✔the pest population density that causes losses equal to the cost
|| || || || || || || || || || || || || || ||
of control measures
|| ||
Action threshold - ✔✔the predetermined level at which pest control is needed
|| || || || || || || || || || ||
Certified applicator - ✔✔A person qualified to apply or supervise the application of
|| || || || || || || || || || || || ||
restricted-use pesticides. ||
Private applicator - ✔✔A certified applicator who uses or supervises the use of any
|| || || || || || || || || || || || || ||
restricted-use pesticide to produce an agricultural commodity. || || || || || ||
Commercial applicator - ✔✔A certified applicator who uses or supervises the use of
|| || || || || || || || || || || || ||
pesticides for purposes other than those covered under a private applicator certification.
|| || || || || || || || || || ||
Food Quality Protection Act (FQPA) - ✔✔set pesticide limits in food, & all active and
|| || || || || || || || || || || || || || ||
inactive ingredients must be screened for estrogenic/endocrine effects. (Amended FIFRA)
|| || || || || || || || || ||
Review old pesticides and aggregate/cumulative exposure.
