Newcomers and Old Friends: Long‐Distance and Bridgehead Introductions Both Contribute to the Recent Invasion of the Little Fire Ant in Southern Europe

Diversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim Biological invasions result from the combination of (i) population dispersal opportunities and (ii) adaptations to the recipient environment. Identifying complex migration histories, made of long‐distance dispersal from the native range and secondary introductions, or genetic patterns indicative of adaptation is crucial to build coherent ...

Detection and characterization of Wolbachia infections in laboratory and natural populations of different species of tsetse flies (genus Glossina)

BMC Microbiology, 2012
Background Wolbachia is a genus of endosymbiotic α-Proteobacteria infecting a wide range of arthropods and filarial nematodes. Wolbachia is able to induce reproductive abnormalities such as cytoplasmic incompatibility (CI), thelytokous parthenogenesis ...

Discrimination Against Non‐Nestmates Functions to Exclude Socially Parasitic Conspecifics in an Ant

Ethology, Volume 131, Issue 3, March 2025.
ABSTRACT Social animals utilise various communication methods to organise their societies. In social insects, nestmate discrimination plays a crucial role in regulating colony membership. Counter to this system, socially parasitic species employ diverse behavioural and chemical strategies to bypass their host's detection.

Effects of parthenogenesis and geographic isolation on female sexual traits in a parasitoid wasp.

, 2009
International audiencePopulation divergence in sexual traits is affected by different selection pressures, depending on the mode of reproduction. In allopatric sexual populations, aspects of sexual behavior may diverge due to sexual selection.

Wolbachia infection in Argentinean populations of Anastrepha fraterculus sp1: preliminary evidence of sex ratio distortion by one of two strains

BMC Microbiology, 2019
Background Wolbachia, one of the most abundant taxa of intracellular Alphaproteobacteria, is widespread among arthropods and filarial nematodes. The presence of these maternally inherited bacteria is associated with modifications of host fitness ...

No evidence for Wolbachia-induced parthenogenesis in the social Hymenoptera

, 2000
In some parasitoid wasps, infection by the micro-organism Wolbachia leads to asexual reproduction. Within the Hymenoptera, the limits of distribution of parthenogenesis inducing Wolbachia have not yet been established.

Genetics of female functional virginity in the Parthenogenesis-Wolbachia infected parasitoid wasp Telenomus nawai (Hymenoptera: Scelionidae)

, 2005
A lepidopteran egg parasitoid species Telenomus nawai consists of two distinct populations with different reproductive modes. One is a completely thelytokous population consisting of females only, whereas the other displays arrhenotokous reproduction ...

Identification of Wolbachia Strains in Two Sibling Species of Neoseiulus Predatory Mites and Their Prey

Yüzüncü Yıl Üniversitesi Tarim Bilimleri Dergisi
Wolbachia screening in mites is necessary for understanding of how their biological functions can be affected, including development of approaches to induce parthenogenesis, making the predator’s cultures more effective and stable.
