Population genetic analysis of the endangered Mottled Duskywing butterfly (Erynnis martialis) informs species reintroduction

Insect Conservation and Diversity, EarlyView.
Mottled Duskywing (Erynnis martialis) populations had moderate levels of genetic diversity at microsatellites with expected heterozygosity ranging from 0.43 to 0.58, and populations more than 10 km apart were differentiated from one another. Weak patterns of isolation by distance and low effective population sizes suggest that all but the largest ...

Detection and quantification of natural Wolbachia in Aedes aegypti in Metropolitan Manila, Philippines using locally designed primers

Frontiers in Cellular and Infection Microbiology
BackgroundThe Philippines bears health and economic burden caused by high dengue cases annually. Presently, the Philippines still lack an effective and sustainable vector management. The use of Wolbachia, a maternally transmitted bacterium, that mitigate

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.

Natural Wolbachia infection in field-collected Anopheles and other mosquito species from Malaysia

Parasites & Vectors, 2020
Background The endosymbiont bacterium Wolbachia is maternally inherited and naturally infects some filarial nematodes and a diverse range of arthropods, including mosquito vectors responsible for disease transmission in humans.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Variation in antiviral protection mediated by different Wolbachia strains in Drosophila simulans. [PDF]

PLoS Pathogens, 2009
Drosophila C virus (DCV) is a natural pathogen of Drosophila and a useful model for studying antiviral defences. The Drosophila host is also commonly infected with the widespread endosymbiotic bacteria Wolbachia pipientis.

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

Insect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Widespread presence of Wolbachia in an Alpine population of the viviparous leaf beetle Oreina cacaliae (Coleoptera: Chrysomelidae) [PDF]

, 2014
Oreina cacaliae (Coleoptera: Chrysomelidae) is a rare example of viviparous insect, able to feed on toxic plants and sequester toxic compounds. Here we present the results of a study on the microbiota associated with O.

Wolbachia-driven host miRNAs mediate arthropod reproduction in a Wolbachia density-dependent manner

Communications Biology
Wolbachia is a widespread endosymbiont and a promising tool for pest control due to its ability to manipulate arthropod reproduction. However, how Wolbachia shapes host microRNA regulation remains poorly understood.

RNA activation in insects: From emerging evidence to molecular applications

Insect Molecular Biology, EarlyView.
Canonical RNA activation involves small RNAs interacting with promoter sequences, but there is also evidence of non‐canonical RNAa in eukaryotes. Emerging evidence suggests the presence of RNAa in insects. RNAa can be utilised as a tool for functional genomic studies in insects.
