The paper tracks the rapid spread and subsequent decline of a feminizing Wolbachia strain in a butterfly population, showing significant shifts in sex ratio over a few years.

The paper reports genome expansion in two co-infecting heritable symbionts, attributing it to host-related factors rather than a common mobile element invasion.

The paper examines the temporal variation in Spiroplasma infection prevalence in two Drosophila hydei populations over time.

This study identifies a novel male-killing mechanism in Wolbachia that persists despite the presence of a male-killing suppressor in its host.

This study shows that the prophage-encoded Hm-oscar gene in the tea tortrix moth causes male lethality, similar to Wolbachia-induced male killing in other insects.

This study uses cell transinfection and comparative genomics to show that Wolbachia strains inducing male killing or feminization affect sex-determining gene splicing in Lepidoptera, while some non-inducing strains also influence sex determination through different mechanisms.

The paper tracks the rapid spread of Wolbachia in a butterfly population, causing a drastic shift from a 1:1 sex ratio to a female-biased ratio of 94.4% in 4 years.
