ABSORPTION
Correct Answer: The movement of a chemical into plants, animals (including humans), and/or microorganisms. ACARICIDE Correct Answer: A pesticide used to control mites and ticks. Amiticide is an acaricide. ACTIVE INGREDIENT Correct Answer: The chemical or chemicals in a pesticide responsible for killing, poisoning, or repelling the pest. Listed separately in the ingredient statement. ACUTE TOXICITY Correct Answer: The capacity of a pesticide to cause injury within 24 hours following exposure. LD50 and LC are common indicators of the degree of acute toxicity.
(See also chronic toxicity). ADJUVANT Correct Answer: A substance added to a pesticide to improve its effectiveness or safety. Same as additive. Examples: penetrants, spreader-stickers, and wetting agents. ADSORPTION Correct Answer: The process by which chemicals are held or bound to a surface by physical or chemical attraction. Clay and high organic soils tend to adsorb pesticides. AGGREGATION PHEROMONE Correct Answer: See pheromone. AEROSOL Correct Answer: Amaterial stored in a container under pressure. Fine droplets are produced when the material dissolved in a liquid carrier is released into the air from the pressurized container. ALGAE
ARTHROPOD
Correct Answer: An invertebrate animal characterized by a jointed body and limbs and usually a hard body covering that is molted at intervals. For example, insects, mites, and crayfish are in the phylum Arthropoda. ATTRACTANT Correct Answer: A substance or device that will lure pests to a trap or poison bait. AVICIDE Correct Answer: A pesticide used to kill or repel birds. Birds are in the class Aves. BACTERIA Correct Answer: Microscopic organisms, some of which are capable of producing diseases in plants and animals. Others are beneficial. BACTERICIDE Correct Answer: Chemical used to control bacteria.
BAIT

BARRIER APPLICATION Correct Answer: Application of a pesticide in a strip alongside or around a structure, a portion of a structure, or any object. BENEFICIAL INSECT Correct Answer: An insect that is useful or helpful to humans; usually insect parasites, predators, pollinators, etc. BIOLOGICAL CONTROL Correct Answer: Control of pests using predators, parasites, and disease-causing organisms. May be naturally occurring or introduced. BIOMAGNIFICATION Correct Answer: The process whereby one organism accumulates chemical residues in higher concentrations from organisms it consumes.
CARCINOGENIC
Correct Answer: The ability of a substance or agent to induce malignant tumors (cancer). CARRIER Correct Answer: An inert liquid, solid, or gas added to an active ingredient to make a pesticide dispense effectively. Acarrier is also the material, usually water or oil, used to dilute the formulated product for application. CEPHALOTHORAX Correct Answer: Combination of the head and thorax in a spider; eight legs are attached to the cephalothorax. CERCI—Short appendages emerging from the abdominal segment of an insect (may help to identify an insect species). CERTIFIED APPLICATORS Correct Answer: Individuals who are certified to use or supervise the use of any restricted-use pesticide covered by their certification.
CHELICERAE
Correct Answer: Two short, needle-tipped appendages that are part of a spider's mouthparts. CHEMICAL NAME Correct Answer: The scientific name of the active ingredient(s) found in the formulated product. This complex name is derived from the chemical structure of the active ingredient. CHEMICAL CONTROL Correct Answer: Pesticide application to kill pests. CHEMOSTERILANT Correct Answer: A chemical compound capable of preventing animal reproduction. CHEMTREC Correct Answer: The Chemical Transportation Emergency Center has a toll-free number (800- 424 - 9300) that provides 24 - hour information for chemical emergencies such as a spill, leak, fire, or accident.
other than that producing an agricultural commodity. COMMON NAME Correct Answer: Aname given to a pesticide's active ingredient by a recognized committee on pesticide nomenclature. Many pesticides are known by a number of trade or brand names, but each active ingredient has only one recognized common name. COMMUNITY Correct Answer: The various populations of animal species (or plants) that exist together in an ecosystem. (See also population and ecosystem). CONCENTRATION Correct Answer: Refers to the amount of active ingredient in a given volume or weight of formulated product. CONTACT PESTICIDE Correct Answer: A compound that causes death or injury to insects when it contacts them. It does not have to be ingested. Often used in reference to a spray
applied directly on a pest. CONTAMINATION Correct Answer: The presence of an unwanted substance (sometimes pesticides) in or on plants, animals, soil, water, air, or structures. CRACK AND CREVICE TREATMENT Correct Answer: The application of small amounts of insecticides into cracks and crevices in which insects hide or through which they may enter a building or travel in it. CRAWLSPACE Correct Answer: Ashallow space below the living quarters of at least a partially basementless house, normally enclosed by the foundation wall. CULTURAL CONTROL Correct Answer: A pest control method that includes changing human habits—e.g., sanitation, work practices, cleaning and garbage pickup schedules, etc.
acute illness or injury to a human or animal when absorbed through the skin. (See exposure route.) DESICCANT Correct Answer: A type of pesticide that draws moisture or fluids from a pest, causing it to die. Certain desiccant dusts destroy the waxy outer coating that holds moisture within an insect's body. DETOXIFY Correct Answer: To render a pesticide's active ingredient or other poisonous chemical harmless. DIAGNOSIS Correct Answer: The positive identification of a problem and its cause. DILUENT Correct Answer: Any liquid, gas, or solid material used to dilute or weaken a concentrated pesticide. DISINFECTANT Correct Answer: Achemical or other agent that kills or
inactivates disease-producing microorganisms. Chemicals used to clean or surface-sterilize inanimate objects. DOSE, DOSAGE Correct Answer: Quantity, amount, or rate of pesticide applied to a given area or target. DRIFT Correct Answer: The airborne movement of a pesticide spray or dust beyond the intended target area. DUST Correct Answer: A finely ground, dry pesticide formulation containing a small amount of active ingredient and a large amount of inert carrier or diluent such as clay or talc. ECOSYSTEM Correct Answer: The pest management unit. It includes a community (of populations) with the necessary physical (harborage, moisture, temperature), and biotic (food, hosts) supporting factors that allow an infestation of pests to persist.
ENDANGERED SPECIES
Correct Answer: A plant or animal species whose population is reduced to the extent that it is near extinction and that a federal agency has designated as being in danger of becoming extinct. ENTRY INTERVAL Correct Answer: See re-entry interval. ENVIRONMENT Correct Answer: All of our physical, chemical, and biological surroundings, such as climate, soil, water, and air, and all species of plants, animals, and microorganisms. ENVIRONMENTAL PROTECTION AGENCY OR EPA Correct Answer: The federal agency responsible for ensuring the protection of humans and the environment from potentially adverse effects of pesticides. EPA ESTABLISHMENT NUMBER Correct Answer: A number assigned to each pesticide production plant by the EPA.
The number indicates the plant at which the pesticide product was produced and must appear on all labels of that product. EPA REGISTRATION NUMBER Correct Answer: An identification number assigned to a pesticide product when the product is registered by the EPA for use. The number must appear on all labels for a particular product. ERADICATION Correct Answer: The complete elimination of a (pest) population from a designated area. EXOSKELETON Correct Answer: The external hardened covering or skeleton of an insect to which muscles are attached internally; periodically shed. EXPOSURE ROUTE OR COMMON EXPOSURE ROUTE Correct Answer: The manner (dermal, oral, or inhalation/respiratory) by which a pesticide may enter an organism.
FOG TREATMENT
Correct Answer: A fine mist of pesticide in aerosolsized droplets (under 40 microns). Not a mist or gas. After propulsion, fog droplets fall to horizontal surfaces. FORMULATION Correct Answer: The pesticide product as purchased, containing a mixture of one or more active ingredients, carriers (inert ingredients), and other additives making it easy to store, dilute, and apply. FUMIGANT Correct Answer: A pesticide formulation that volatilizes, forming a toxic vapor or gas that kills in the gaseous state. Usually, it penetrates voids to kill pests. FUNGICIDE Correct Answer: Achemical used to control fungi. FUNGUS (plural, fungi) Correct Answer: A group of small, often microscopic, organisms in the plant kingdom that cause rot, mold and disease. Fungi need moisture or a damp environment
(wood rots require at least 19 percent moisture). Fungi are extremely important in the diet of many insects.
