INTRODUCTION
This examination evaluates professional competency in mosquito and biting fly pest
control, focusing on applied knowledge required for safe, effective, and legally compliant
pest management operations. It assesses understanding of insect biology, vector ecology,
pesticide selection and application, integrated pest management principles, and
,environmental considerations. Candidates will face multiple-choice and scenario-based
questions designed to reflect real-world decision-making situations. The exam emphasizes
regulatory compliance, worker safety, environmental protection, and public health
responsibility. Successful performance requires not only memorization of concepts but
also the ability to apply scientific reasoning and field-based judgment in mosquito and
biting fly control operations.

SECTION ONE: QUESTIONS 1–50
════════════════════════════════════
Question 1
Which stage of the mosquito life cycle is fully aquatic?
A. Egg, larva, and pupa
B. Adult only
C. Egg only
D. Larva and pupa only
🟢 Correct Answer: D. Larva and pupa only
🔴 Explanation: Mosquito larvae and pupae develop in water, while eggs may be laid on
water or moist surfaces depending on species.
,Question 2
What is the primary purpose of larviciding in mosquito control?
A. Kill adult mosquitoes
B. Prevent egg laying
C. Eliminate immature aquatic stages
D. Repel mosquitoes from humans
🟢 Correct Answer: C. Eliminate immature aquatic stages
🔴 Explanation: Larvicides target larvae and pupae before they develop into biting adults,
reducing population emergence.
Question 3
Which disease is commonly associated with mosquitoes in public health concerns?
A. Lyme disease
B. West Nile virus
C. Rabies
D. Tetanus
🟢 Correct Answer: B. West Nile virus
🔴 Explanation: West Nile virus is transmitted by mosquitoes, particularly Culex species.
, Question 4
Which mosquito stage is most resistant to drying conditions?
A. Larva
B. Adult
C. Egg
D. Pupa
🟢 Correct Answer: C. Egg
🔴 Explanation: Some mosquito eggs can survive desiccation until rehydrated by water.
Question 5
Which method is considered a biological control for mosquitoes?
A. Oil application
B. Bacillus thuringiensis israelensis (Bti)
C. Fogging with pyrethroids
D. Drainage ditching
🟢 Correct Answer: B. Bacillus thuringiensis israelensis (Bti)
🔴 Explanation: Bti is a bacterial larvicide used specifically to target mosquito larvae
biologically.
