Question 1: Larval Development Rate

The larval development rate (R_L) depends primarily on which factor?

Question 2: Degree-Days Parameter

According to Jepson (1947), what is the value of K_L (degree-days required for larval development)?

Question 3: Larval Mortality Factors - Multiple Select

Select ALL factors that contribute to larval mortality in VECTRI:

Question 4: Base Larval Survival

What is the approximate base daily survival rate for larvae in "good" conditions?

Question 5: Flushing Effect

Which larval stage is MOST affected by rainfall-driven flushing?

Question 6: Gonotrophic Cycle

The gonotrophic cycle represents the time from:

Question 7: Eggs Per Cycle

How many female eggs does each completed gonotrophic cycle typically produce?

Question 8: Sporogonic Cycle

What does the Extrinsic Incubation Period (EIP) represent?

Question 9: Temperature and EIP

What happens to the EIP at 20°C compared to 25°C?

Question 10: Vector Survival - Multiple Select

Select ALL true statements about adult mosquito survival in VECTRI:

Question 11: Expected Lifespan

If daily survival probability is 0.9, what is the approximate expected mosquito lifespan?

Question 12: Indoor Temperature

How does indoor temperature typically compare to outdoor temperature in VECTRI?

Question 13: Human Biting Rate

What happens to mosquito biting behavior at LOW human population densities?

Question 14: Daily EIR

The daily Entomological Inoculation Rate (EIR) is calculated as:

Question 15: Immunity Dynamics

At an annual EIR of ~100, approximately what percentage of individuals become clinically immune?

Question 16: Surface Hydrology Components - Multiple Select

Select ALL components that contribute to total breeding area (w):

Question 17: Water Balance

What causes temporary ponds to shrink in the VECTRI water balance model?

Question 18: Carrying Capacity Effect

If w (breeding area fraction) is SMALL, what happens to larval survival?

Question 19: Semi-Arid vs Humid Regions

In semi-arid regions with intense but short rainstorms, what typically limits transmission?

Question 20: True or False

In VECTRI, egg and pupa stages are temperature-dependent with variable durations.

💡 Tips for Success

  • Read each question carefully - many involve specific numerical values
  • Think about the biological and physical processes before answering
  • For multiple select questions, select ALL correct answers
  • Remember the interconnections between components (e.g., temperature affects development, survival, and EIP)
  • Review your answers before submitting
  • Check the feedback to deepen your understanding
  • Retake the quiz to improve your score!
