Do Wolbachia influence fecundity in Nasonia vitripennis? [PDF]
Heredity, 2000 This paper reports the influence of a vertically transmitted symbiont, Wolbachia, on host fitness in the parasitic wasp, Nasonia vitripennis. We measured fecundities of uninfected strains and strains infected with either two Wolbachia variants (wAv,wBv) or one (wAv or wBv). Preliminary tests suggested that double-infected females produce more offspring

Aromatic plants, nest bacterial diversity, and nestling condition in Corsican blue tits
Oikos, EarlyView.According to the ‘nest protection hypothesis', some passerines incorporate fresh aromatic plants into their nests which reduce pathogens that can negatively affect nestlings. We experimentally evaluated the effect of five aromatic plant species on the nest bacterial microbiota of Corsican blue tits Cyanistes caeruleus.

Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]
, 2015 BackgroundInsects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory

Males of the parasitoid wasp, Nasonia vitripennis, can identify which fly hosts contain females
Royal Society Open Science, 2022 The reproductive success of a male is limited by the number of females it can mate with. Thus, males deploy elaborate strategies to maximize access to females.

Insect Molecular Biology, EarlyView.Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

The transcriptomic basis of oviposition behaviour in the parasitoid wasp Nasonia vitripennis.
PLoS ONE, 2013 Linking behavioural phenotypes to their underlying genotypes is crucial for uncovering the mechanisms that underpin behaviour and for understanding the origins and maintenance of genetic variation in behaviour.

A Margulian View of Symbiosis and Speciation: the Nasonia Wasp System
Symbiosis, 2022 Species are fundamental units of biology that exemplify lineage diversification, while symbiosis of microbes and macrobial hosts exemplify lineage unification between the domains of life.

Insect Molecular Biology, EarlyView.Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially

Chemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality. [PDF]
, 2015 Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of ...

Ecology and Evolution, Volume 16, Issue 2, February 2026.Two distinct lineages of L. invasa and the dominant endosymbiont, Rickettsia, was identified, followed by an analysis of its infection density across various developmental stages and tissues of L. invasa. Furthermore, two distinct strains of the Rickettsia endosymbiont were detected, and the phylogenetic relationships between these strains and their L.
