ANSWERS
300 QUESTIONS AND ANWERS
1. Q: What order do mosquitoes belong to? A: Diptera (true flies)
2. Q: What family do mosquitoes belong to? A: Culicidae
3. Q: How many life stages do mosquitoes have? A: Four stages (egg, larva,
pupa, adult) - complete metamorphosis
4. Q: Which mosquito life stages are aquatic? A: Egg, larva, and pupa stages
are aquatic
5. Q: How long does the mosquito life cycle typically take? A: 7-14 days
under optimal conditions, but varies with temperature and species
6. Q: What is the scientific term for mosquito larvae? A: Wigglers (due to
their characteristic movement)
7. Q: What is the scientific term for mosquito pupae? A: Tumblers (due to
their tumbling motion when disturbed)
8. Q: Do male mosquitoes bite humans? A: No, only female mosquitoes bite
humans for blood meals
9. Q: What do male mosquitoes feed on? A: Nectar, plant juices, and other
sugar sources
10. Q: Why do female mosquitoes need blood meals? A: To obtain proteins
necessary for egg development
11. Q: How many eggs can a female mosquito lay at one time? A: Typically
100-300 eggs per batch
12. Q: What are the three main genera of mosquitoes of medical
importance? A: Aedes, Anopheles, and Culex
,13. Q: Which mosquito genus is the primary vector for malaria? A:
Anopheles
14. Q: Which mosquito genus is associated with dengue fever transmission?
A: Aedes (specifically Aedes aegypti)
15. Q: What is the primary breeding habitat for Culex mosquitoes? A:
Polluted or organically enriched water sources
16. Q: How do you identify Anopheles larvae in water? A: They lie parallel
to the water surface without a siphon tube
17. Q: How do Aedes and Culex larvae position themselves in water? A:
They hang at an angle from the water surface using their siphon tube
18. Q: What is the siphon tube used for in mosquito larvae? A: Breathing - it
extends to the water surface to obtain oxygen
19. Q: How long can mosquito eggs survive without water? A: Some species
(like Aedes) can survive months to over a year in dry conditions
20. Q: What triggers mosquito egg hatching? A: Flooding or submersion in
water, often combined with reduced oxygen levels
21. Q: How many times do mosquito larvae molt? A: Four times, creating
four larval instars
22. Q: What do mosquito larvae eat? A: Organic matter, bacteria, algae, and
small particles filtered from water
23. Q: How do mosquito larvae breathe? A: Through spiracles connected to a
siphon tube (except Anopheles)
24. Q: What is the pupation period for mosquitoes? A: Typically 1-3 days
25. Q: Do mosquito pupae feed? A: No, pupae do not feed during this non-
feeding stage
26. Q: How far can mosquitoes typically fly? A: Most species fly 1-3 miles,
though some can travel up to 20 miles
27. Q: What is the typical lifespan of an adult mosquito? A: Females: 2-8
weeks; Males: 1-2 weeks
28. Q: At what temperature do mosquitoes become inactive? A: Below 50°F
(10°C) for most species
, 29. Q: What is the optimal temperature range for mosquito development?
A: 77-86°F (25-30°C)
30. Q: How do mosquitoes overwinter in temperate climates? A: As eggs,
larvae, or hibernating adults depending on species
31. Q: What is diapause in mosquitoes? A: A state of suspended development
during unfavorable conditions
32. Q: How do mosquitoes locate their hosts? A: Through CO2, body heat,
moisture, and chemical attractants
33. Q: What distance can mosquitoes detect CO2? A: Up to 100 feet away
34. Q: What time of day are most mosquitoes active? A: Dawn and dusk
(crepuscular activity)
35. Q: Which mosquito species are day-biters? A: Aedes species, particularly
Aedes aegypti
36. Q: What is the feeding behavior called when mosquitoes take multiple
blood meals? A: Interrupted feeding or multiple feeding
37. Q: How long does it take for a mosquito to complete a blood meal? A: 3-
5 minutes for a complete feeding
38. Q: What happens to mosquitoes in winter? A: They enter diapause, die,
or migrate to warmer areas
39. Q: What is the gonotrophic cycle? A: The time between blood meal and
egg laying (typically 2-3 days)
40. Q: How many gonotrophic cycles can one female complete? A: Multiple
cycles throughout her lifetime (3-5 on average)
41. Q: What is autogeny in mosquitoes? A: The ability to develop eggs
without a blood meal
42. Q: Which mosquito species exhibit autogeny? A: Some Culex and Aedes
species in their first gonotrophic cycle
43. Q: What is stenogamy in mosquitoes? A: Mating in confined spaces
(important for laboratory rearing)
44. Q: Where do mosquitoes typically mate? A: In swarms, usually around
landmarks or over breeding sites
