Overview

Entomological study reveals sex-specific Wolbachia strain dynamics and lower superinfection in Aedes albopictus, highlighting challenges for mosquito biocontrol strategies.

Key Points

  • Characterize the natural infection status, density, and environmental determinants of Wolbachia strains (wAlbA and wAlbB) in wild Aedes albopictus populations.
  • Sampled wild Aedes albopictus mosquitoes (N = 399) across Oʻahu and the Island of Hawaiʻi.
  • Quantified the infection prevalence and density of wAlbA and wAlbB using quantitative PCR across sex, island, temperature, and precipitation variables.
  • Wolbachia infected 98.5% (N = 399) of mosquitoes; all infected individuals carried wAlbB, but only 28.6% were superinfected with wAlbA.
  • Females were significantly more likely to harbor wAlbA and maintained significantly higher densities of both strains compared to males.
  • Strain densities correlated positively in females but not males, while wAlbA prevalence varied with island and precipitation without significant variation in wAlbB prevalence.
