SECTION 1: PEST BIOLOGY & IDENTIFICATION (Questions 1-30)
Question 1 What are the stages of development in complete metamorphosis?
Answer: Egg, larva, pupa, adult
Rationale: Complete metamorphosis (holometabolous development) includes four distinct life stages: egg, larva (feeding stage), pupa (resting/transforming stage), and adult (reproductive stage).
Question 2 Which stage in complete metamorphosis normally causes the most damage by feeding?
Answer: Larva
Rationale: The larval stage is primarily responsible for feeding and growth, causing the majority of damage to structures, food sources, and materials.
Question 3 What type of physical damage is caused by ants?
Answer: Chewing
Rationale: Ants have mandibles designed for chewing, allowing them to damage wood, insulation, food packaging, and other materials.
Question 4 What is the diet of bedbugs?
Answer: Blood
Rationale: Bedbugs are obligate hematophages, meaning they feed exclusively on blood from warm-blooded hosts, typically humans.
Question 5 What type of environment is preferred by centipedes?
Answer: Dark and moist places
Rationale: Centipedes require high humidity to survive and are nocturnal, seeking dark, damp environments such as basements, crawlspaces, and under decaying organic matter.
Question 6 How soon after flies lay eggs will the eggs hatch?
Answer: Within 24 hours
Rationale: Fly eggs typically hatch within 24 hours under favourable temperature conditions, making rapid population growth possible.
Question 7 Where do bees overwinter?
Answer: In the hive
Rationale: Honey bees survive winter by clustering inside the hive, generating heat through muscle vibration and consuming stored honey for energy.
What is the apparatus by which insects breathe?
Answer: Spiracles
Rationale: Insects respire through a network of tracheal tubes that open to the exterior via paired openings called spiracles located along the thorax and abdomen.
Question 13 What is the term used to describe the changes in shape of body form through which insects go?
Answer: Metamorphosis
Rationale: Metamorphosis refers to the series of physical changes insects undergo from egg to adult, categorized as no metamorphosis, gradual metamorphosis (hemimetabolous), or complete metamorphosis (holometabolous).
Question 14 Which species develop without metamorphosis?
Answer: Silverfish
Rationale: Silverfish are ametabolous insects—they hatch from eggs resembling miniature adults and continue to molt throughout their lives without significant body form changes.
Question 15 Which species undergo gradual metamorphosis?
Answer: Cockroaches
Rationale: Cockroaches are hemimetabolous insects; their young (nymphs) resemble adults but lack fully developed wings and reproductive organs.
Question 16 Which insects do not go through metamorphosis?
Answer: Firebrats, Springtails, Silverfish
Rationale: These primitive insects are ametabolous, meaning they undergo no metamorphosis and emerge from eggs as smaller versions of adults.
Question 17 Which insects go through gradual metamorphosis?
Answer: Cockroaches, Crickets, Bedbugs/Mites, Booklice
Rationale: These insects are hemimetabolous, with nymphs resembling adults but requiring multiple molts to reach sexual maturity.
Question 18 Which insects go through complete metamorphosis?
Answer: Moths and Fleas, Flies and Beetles, Bees and Wasps, Ants
Rationale: These orders are holometabolous, undergoing four distinct life stages: egg, larva, pupa, and adult, with the larval stage looking completely different from the adult.
Question 19 What are the stages of gradual metamorphosis?
Answer: Egg, Nymph, Adult
Rationale: Gradual metamorphosis involves only three stages: egg, nymph (which resembles a small adult), and adult.
Question 20 Ants require what three things in order to survive?
Answer: Food, water, shelter
Rationale: Like all living organisms, ants need food sources (insects, honeydew, sweets), water for hydration, and shelter (nest sites) for colony survival.
Question 25 Which chemical family is approved for use to treat bedbugs?
Answer: Synthetic Pyrethroids
Rationale: Synthetic pyrethroids are the primary chemical class registered for bed bug control in Canada, though resistance has been documented; integrated pest management approaches are recommended.
Question 26 What are chelicera?
Answer: Fangs of a spider
Rationale: Chelicerae are the paired mouthparts of arachnids used to grasp and inject venom into prey or for defense.
Question 27 What is the diet of bedbugs?
Answer: Blood
Rationale: Bedbugs are obligate hematophages—they require blood meals for development, molting, and reproduction.
Question 28 What species of recluse spider is found in the Southwest?
Answer: The Desert Recluse
Rationale: The desert recluse (Loxosceles deserta) is the recluse spider species found in southwestern North America, including parts of Alberta.
Question 29 What are identifying features of a Wolf Spider?
Answer: Large, hairy spider; three rows of eyes (most spiders have two rows); three tiny claws on each leg; hunts prey rather than weaving webs; can inflict serious bites
Rationale: These characteristics distinguish wolf spiders from other spider families (Lycosidae). They are active hunters with excellent vision.
Question 30 What are identifying features of an Orb Weaver Spider?
Answer: Known for beautiful spoke-patterned webs; medium to large-sized; body about half-inch to an inch; large abdomen; fairly long legs; many have colour markings
Rationale: Orb weavers (family Araneidae) construct the classic circular webs seen between trees or shrubs. Several species can inflict bites on humans.
SECTION 2: PEST CONTROL METHODS & PESTICIDE CLASSIFICATION (Questions 31-50)
Question 31 Which of the following is an example of mechanical control?
Answer: Installing screens, caulking cracks and holes, and sticky traps
Rationale: Mechanical control methods physically prevent pests from entering structures or capture them without using chemicals.
Question 32 At what stage in the life cycle will pesticides usually be most effective?
Answer: Larval/Nymph
Rationale: The larval or nymph stage is often the most vulnerable to pesticide application because these stages are actively feeding and have less developed protective structures.
Question 33 What are the three categories in which insecticides are classified?
Rationale: Acute rodenticides are highly toxic and cause death after a single feeding. They are fast-acting compared to anticoagulants.
Question 38 What is an advantage of using anticoagulants for rodent control?
Answer: They do not cause bait shyness
Rationale: Anticoagulant rodenticides are multiple-dose products that cause delayed death, allowing rodents to feed multiple times without associating the bait with illness.
Question 39 What are advantages of single-dose anticoagulants?
Answer: Require only a single feeding, control warfarin-resistant pests, less risk of secondary poisoning
Rationale: Second-generation anticoagulants are effective at lower concentrations, control resistant populations, and have reduced secondary poisoning potential compared to earlier formulations.
Question 40 What is an important safety factor when using a multiple-dose rodenticide?
Answer: Single doses are seldom lethal to non-target organisms
Rationale: Multiple-dose anticoagulants require several feedings to achieve a lethal dose, providing a safety margin for non-target species that may consume small amounts.
Question 41 What are the three categories in which insecticides are classified?
Answer: Stomach poisons, contact poisons, fumigants
Rationale: The classification system helps applicators select appropriate products based on the pest's biology and the application site.
Question 42 At what stage in the life cycle will pesticides usually be most effective?
Answer: Larval/Nymph
Rationale: Young pests are more susceptible because they feed more actively and have thinner cuticles.
Question 43 Which of the following is an example of mechanical control?
Answer: Installing screens, caulking cracks, sticky traps
Rationale: Mechanical control methods physically exclude or capture pests, reducing reliance on chemical interventions.
Question 44 What is an example of a biological control method?
Answer: Introduction of parasitoid wasps for aphid control
Rationale: Biological control uses living organisms to suppress pest populations (predators, parasitoids, pathogens), often as part of an IPM program.
Question 45 What is the best pesticide application method for treating wall voids?
Answer: Dust formulation with a bulb duster or puffer
Rationale: Dusts remain effective longer in voids, are not absorbed by porous materials, and can reach areas inaccessible to liquid sprays.
Answer: Discard all infested food products, clean shelves thoroughly, and install pheromone traps for monitoring
Rationale: Indian meal moth control requires source elimination of infested dry goods (flour, cereal, pet food). Insecticides are not applied directly to food contact surfaces.
SECTION 3: PESTICIDE LABELS & TOXICITY (Questions 51-70)
Question 51 What are the 11 key parts of a pesticide label?
Answer:
- Classification of pesticide use
- Product name
- Type of formulation
- Ingredient statement
- Net contents of container
- Signal word
- Name of manufacturing company
- EPA registration and establishment numbers
- Directions for use
- Hazard statement
- Storage and disposal information
Rationale: Every registered pesticide label in Canada must contain these essential elements as required by the Pest Control Products Act and Regulations.
Question 52 What is the Toxicity Category 1 signal word, and what does it signify?
Answer: DANGER. It signifies 'Highly Toxic'. LD50 = 0 to 50 mg/kg.
Rationale: Signal words indicate acute toxicity based on LD50 values. DANGER is the highest warning level, requiring extreme caution.
Question 53
What is the Toxicity Category 2 signal word, and what does it signify?
Answer: WARNING. It signifies 'Moderately Toxic'. LD50 = 50 to 500 mg/kg.
Rationale: WARNING indicates moderate acute toxicity, requiring appropriate PPE and handling precautions.
Question 54 What is the Toxicity Category 3 signal word, and what does it signify?
Answer: CAUTION. It signifies 'Slightly Toxic'. LD50 = 500 to 5000 mg/kg.
Rationale: CAUTION products have low acute toxicity but still require safe handling practices.
Question 55 What is the Toxicity Category 4 signal word, and what does it signify?
Answer: No signal word is required. It signifies 'Relatively Non-toxic'.
Rationale: Products with LD50 values above 5000 mg/kg do not require a signal word, but the label still requires hazard statements and handling instructions.
Question 56 Who is directly affected by a pesticide application performed in an apartment building in units, laundry area, and hallways?
Answer: Tenants whose suites are being treated, any workers working the areas, door attendants, housekeeping staff, any tenants that have access to common areas
Rationale: All individuals who may enter treated areas during or after application (including residents, staff, and service personnel) are potentially affected and must be notified according to regulations.
Question 57 What is the restricted entry interval for most pesticides?
Question 62 What does the "Environmental Hazards" statement on a label warn about?
Answer: Toxicity to birds, bees, and aquatic life
Rationale: This mandatory label section protects non-target organisms by identifying specific environmental risks.
Question 63 What is a "Buffer Zone" on a pesticide label?
Answer: An area where application is prohibited to protect sensitive areas (water bodies, occupied buildings)
Rationale: Buffer zones are legally enforceable distances to prevent pesticide drift into sensitive areas.
Question 64 Where is the antidote information found on a pesticide label?
Answer: In the "First Aid" or "Toxicological" section
Rationale: First aid instructions and medical treatment information must be readily accessible on every label.
Question 65 What does the Precautionary Statement on a pesticide label contain?
Answer: PPE requirements and hazards to humans and domestic animals
Rationale: This section specifies the protective equipment required for safe handling and application.
Question 66
When is a waterproof rainsuit acceptable as pesticide PPE?
Answer: If the pesticide label specifies it as acceptable
Rationale: Not all rainsuits provide adequate chemical barrier; the label description is the definitive guide.
Question 67 What does PCP number on a label indicate?
Answer: The product is registered by PMRA (Health Canada)
Rationale: Pest Control Products (PCP) numbers confirm federal registration under the Pest Control Products Act.
Question 68 What is the purpose of the "Pre-harvest Interval" (PHI) on a label?
Answer: Minimum time between last application and harvest
Rationale: PHIs ensure pesticide residues decline to acceptable levels before crop harvest.
Question 69 Where does the "Directions for Use" section appear on a pesticide label?
Answer: After the ingredient statement and hazard information
Rationale: Directions for Use provide legally binding instructions for proper application of the product.
Question 70 What does "Do not contaminate irrigation ditches" mean on a pesticide label?
Answer: Do not allow pesticide to enter water intended for irrigation
Rationale: Raccoons are omnivorous and destructive; they cause structural damage while foraging for food and nesting sites.
Question 75 How may skunks be controlled?
Answer: Exclusion, shooting, trapping
Rationale: Skunk control options include physical exclusion (sealing entry points) under Alberta regulations; lethal methods require appropriate permits.
Question 76 What types of damage are caused by rats?
Answer: Damage to feeds and foods, physical damage (gnawing, tunneling), disease transmission
Rationale: Rats cause extensive economic damage through consumption and contamination of food, structural damage from gnawing, and transmission of diseases including leptospirosis and salmonella.
Question 77 Which mouse is the carrier for Hantavirus?
Answer: Deer mouse
Rationale: The deer mouse (Peromyscus maniculatus) is the primary reservoir for Sin Nombre virus (hantavirus) in Canada.
Question 78 What is the name commonly used to refer to ground squirrels?
Answer: Gophers
Rationale: In Alberta, Richardson's ground squirrels are commonly called "gophers," though true gophers are different species.
Question 79 What is an acute rodenticide?
Answer: Requires single feeding in a short time frame
Rationale: Acute rodenticides cause death within hours of a single feeding but carry higher non-target risks.
Question 80 What is an advantage of using anticoagulants for rodent control?
Answer: They do not cause bait shyness
Rationale: Because death is delayed, rodents continue feeding without associating the bait with illness.
Question 81 What is an important safety factor when using a multiple-dose rodenticide?
Answer: Single doses are seldom lethal to non-target organisms
Rationale: Multiple-dose anticoagulants require several feedings for lethality, providing a safety margin for non-target species.
Question 82 What are advantages of single-dose anticoagulants?
Answer: Require only a single feeding, control warfarin-resistant pests, less risk of secondary poisoning
Rationale: Second-generation anticoagulants (brodifacoum, bromadiolone) are more potent and effective against resistant populations.
