Which statement is true about Culex salinarius?

• A. Bites only at night
• B. Weak flier; seldom travels far
• C. Attracted to light traps and has multiple generations per year
• D. Overwinters as pupae

Answer: (C)

Culex salinarius is commonly monitored with light traps, and it tends to produce several generations during the warm season. Light traps are a standard tool for tracking mosquito activity because species that are attracted to light will be captured more readily, giving a reliable indication of population levels and activity periods. Having multiple generations per year means the population can rebound or grow quickly between control efforts, which is important for planning timing and frequency of interventions.

The other statements don’t fit as well. This species is not best described as a weak flyer that travels little, since Culex mosquitoes can disperse from breeding sites. It’s not accurate to claim it overwinters as pupae, and bites aren’t limited to just nighttime hours for this species. The combination of being attracted to light traps and having multiple generations per year best reflects its surveillance-detectable behavior and its potential for population buildup.
