Wolbachia infection in wild mosquitoes (Diptera: Culicidae): implications for transmission modes and host-endosymbiont associations in Singapore

Parasites & Vectors, 2020
Background Wolbachia are intracellular bacterial endosymbionts found in most insect lineages. In mosquitoes, the influence of these endosymbionts on host reproduction and arboviral transmission has spurred numerous studies aimed at using Wolbachia ...

Investigating zeta‐cypermethrin resistance stability in California Drosophila suzukii populations

Pest Management Science, Volume 82, Issue 7, Page 6808-6816, July 2026.
After continuous selection and removal of selection pressure in spotted‐wing Drosophila, zeta‐cypermethrin resistance remained stable over several generations. Following a population bottleneck, zeta‐cypermethrin resistance increased without selection, highlighting the importance of insecticide rotation.

The genome of the heartworm, Dirofilaria immitis, reveals drug and vaccine targets [PDF]

, 2012
The heartworm Dirofilaria immitis is an important parasite of dogs. Transmitted by mosquitoes in warmer climatic zones, it is spreading across southern Europe and the Americas at an alarming pace.

Sex Determination in Sponges

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

A Wolbachia Deubiquitylating Enzyme Induces Cytoplasmic Incompatibility

Nature Microbiology, 2017
Wolbachia are obligate intracellular bacteria1 that infect arthropods, including approximately two-thirds of insect species2. Wolbachia manipulate insect reproduction by enhancing their inheritance through the female germline.

Multiple Wolbachia strains provide comparative levels of protection against dengue virus infection in Aedes aegypti

PLoS Pathogens, 2020
The insect bacterium Wolbachia pipientis is being introgressed into Aedes aegypti populations as an intervention against the transmission of medically important arboviruses. Here we compare Ae.

Titer regulation in arthropod-Wolbachia symbioses [PDF]

, 2019
Symbiosis between intracellular bacteria (endosymbionts) and animals are widespread. The alphaproteobacterium Wolbachia pipientis is known to maintain a variety of symbiotic associations, ranging from mutualism to parasitism, with a wide range of ...

"Wolbachia" Infections and Arthropod Reproduction [PDF]

BioScience, 1998
Wolbachia is an intracellular bacterium that is almost exclusively maternally transmitted, and its reproductive effects favor transmission of the intracellular bacterial agent at the expense of the arthropod population that is not infected. Wolbachia can cause cytoplasmic incompatibility, parthenogenesis and feminization in many arthropods.

Rickettsiales in South America: A Systematic Review of Their Molecular Detection and Distribution in Arthropods and Vertebrates

Public Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Bacteria of the order Rickettsiales comprise a diverse group of obligate intracellular microorganisms that are globally distributed and highly prevalent in tropical and subtropical regions. In South America, these bacteria have been associated with arthropod vectors, such as ticks, fleas, mites, lice, and certain dipterans, as well as with a ...

Vertical Transmission of Wolbachia Is Associated With Host Vitellogenin in Laodelphax striatellus

Frontiers in Microbiology, 2018
Wolbachia in host germ lines are essential for their vertical transmission to the next generation. It is unclear how the regulation of host oocyte development influences Wolbachia location and the mechanistic basis of transmission.
