Q1: A livestock farmer notices that rodents are contaminating feed storage areas and spreading disease among
animals. Which integrated pest management (IPM) strategy should be implemented first to effectively reduce the
rodent population while minimizing chemical use?
A. Immediate application of anticoagulant rodenticides in all barns
B. Introduction of natural predators such as cats without environmental changes
C. Elimination of food sources and sealing entry points in storage facilities
D. Increasing the use of broad-spectrum insecticides around feed areas
Correct Answer: C
Rationale: The first step in IPM is prevention by removing attractants and access; eliminating food sources and
sealing entry points reduces rodent survival and reproduction without relying on chemicals.
Q2: A pest control applicator is evaluating signs of ectoparasites in cattle. Which clinical sign most strongly
indicates a heavy infestation of lice?
A. Decreased water consumption
B. Increased milk fat percentage
C. Excessive scratching and hair loss patches
D. Elevated respiratory rate only
Correct Answer: C
1|Page
,Rationale: Lice infestations commonly cause pruritus, leading to scratching, hair loss, and skin irritation, which are
hallmark signs of heavy infestation.
Q3: When applying insecticides to control flies in a poultry house, which factor most significantly affects the
efficacy of the treatment?
A. The color of the insecticide container
B. The age of the poultry
C. Environmental conditions such as temperature and humidity
D. The breed of poultry
Correct Answer: C
Rationale: Temperature and humidity influence insect metabolism and insecticide breakdown, significantly
affecting the performance of control measures.
Question 4: Which pest is most commonly associated with blood loss anemia in cattle?
A. House fly
B. Horn fly
C. Stable fly
D. Face fly
Correct Answer: B
Rationale: Horn flies feed on cattle blood repeatedly throughout the day, leading to irritation, stress, and
significant blood loss in heavy infestations.

,Q5: What is the primary advantage of integrated pest management (IPM) in livestock systems?
A. Eliminates all pesticide use
B. Relies only on biological control
C. Combines multiple control strategies for long-term suppression
D. Uses only chemical control
Correct Answer: C
Rationale: IPM integrates biological, cultural, mechanical, and chemical methods to manage pests effectively while
reducing resistance and environmental impact.
Q6: Which internal parasite is most commonly controlled in cattle using dewormers?
A. Tapeworms only
B. Liver flukes only
C. Gastrointestinal nematodes
D. Protozoa only
Correct Answer: C
Rationale: Gastrointestinal nematodes such as roundworms are the most economically significant internal
parasites in cattle, requiring regular deworming.
Question 7: Which insect is a known vector of pinkeye (infectious bovine keratoconjunctivitis)?
3|Page
, A. Mosquito
B. House fly
C. Face fly
D. Stable fly
Correct Answer: C
Rationale: Face flies are mechanical vectors of Moraxella bovis, the bacteria that causes pinkeye in cattle,
transmitting the pathogen between animals.
Question 8: What is the most effective method for controlling mosquito breeding in livestock environments?
A. Spraying adulticides daily
B. Increasing animal density
C. Eliminating standing water sources
D. Feeding animals insect-repellent supplements
Correct Answer: C
Rationale: Mosquitoes require standing water for breeding; removing these habitats prevents population growth.
Q9: Which PPE is essential when applying pesticides in confined animal housing?
A. Sandals
B. Cotton gloves only
