mosquitoes - 2025 ACF Winter

Question

The bacterium B. thuringiensis secretes toxins that can be used to limit the population of these organisms. For 10 points each:

[10e] What family of small flying insects lay hundreds of eggs in stagnant water and are the main vector of malaria? These blood-sucking insects are attracted to carbon dioxide exhaled by feeding targets.

ANSWER: mosquitoes [or Culicidae]

[10m] As mosquitoes have short lifespans, high mortality rates, and produce many offspring, they can be classified as one letter under this theory. Other organisms classified under a different letter under this theory include whales and pandas.

ANSWER: r/K selection theory [accept r selection or K selection]

[10h] This other hypothesis builds off r/K theory by using differences in life-histories of species to explain physiological and behavioural differences. “Fast” species in this theory are bold, active, and have high metabolism.

ANSWER: pace-of-life syndrome hypothesis [or POLS]
