Investigating the Possibility of Wolbachia‐ and Cardinium‐Induced Parthenogenesis in Two Mite Species

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
In arthropods, thelytokous parthenogenesis, in which females develop from unfertilised eggs, is often associated with reproductive manipulation by endosymbiotic bacteria such as Wolbachia and Cardinium. This study investigated whether thelytokous parthenogenesis in two mite species, Amblyseius herbicolus (Phytoseiidae) and Czenspinskia ...

Evolution of reproductive mode variation and host associations in a sexual-asexual complex of aphid parasitoids

BMC Evolutionary Biology, 2011
Background The Lysiphlebus fabarum group is a taxonomically poorly resolved complex of aphid parasitoids, presently split into three described species that comprise sexual (arrhenotokous) and asexual (thelytokous) lineages of unknown relationship ...

Monitoring spirodiclofen resistance in female Brevipalpus yothersi (Acari: Tenuipalpidae) from citrus orchards in Southeastern Brazil

Agricultural and Forest Entomology, Volume 28, Issue 3, Page 410-424, August 2026.
Spirodiclofen resistance levels in B. yothersi varied geographically across the Brazilian citrus belt, with higher resistance in the central region. Sublethal effects included reduced oviposition, increased non‐viable eggs and disrupted female reproduction.

Wolbachia Infection in Populations of Ostrinia furnacalis: Diversity, Prevalence, Phylogeny and Evidence for Horizontal Transmission

Journal of Integrative Agriculture, 2013
Wolbachia are maternally inherited endosymbiotic bacteria infecting a wide range of arthropods and filarial nematodes. They can induce various reproduction alterations in their hosts, including thelytokous parthenogenesis, cytoplasmic incompatibility (CI)

Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 887-895, August 2026.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Potential Drivers of Successful Biocontrol: A Perspective on Parasitoids

New Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
Parasitoids are central to classical biological control, yet predicting their long‐term effectiveness post release remains challenging. In Aotearoa New Zealand, three Microctonus (Hymenoptera: Braconidae) species have been used against pest weevils, but key aspects of their biology remain poorly understood.

Host‐Associated Bacterial Community Changes After Laboratory Introduction Vary With Wolbachia Presence

Environmental Microbiology, Volume 28, Issue 3, March 2026.
The endosymbiont Wolbachia promotes homogenisation and delays the microbial community response of the parasitic wasp Asobara japonica after a significant environmental change. This suggests that key microbial taxa can mediate community shifts and has important implications for experimental design in microbial ecology, particularly in translating lab ...

Genetic Diversity of the Invasive Gall Wasp Leptocybe invasa (Hymenoptera: Eulophidae) and of its Rickettsia Endosymbiont, and Associated Sex-Ratio Differences.

PLoS ONE, 2015
The blue-gum chalcid Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae) is a gall wasp pest of Eucalyptus species, likely native to Australia. Over the past 15 years it has invaded 39 countries on all continents where eucalypts are grown.

A Set of Novel Venom Proteins Enables Parasitoid Wasps to Exploit Older Hosts and Coexist with Competitors

Advanced Science, Volume 13, Issue 4, 19 January 2026.
This study elucidates a molecular mechanism enabling species coexistence between parasitoid wasps, showing how Asobara japonica uses a set of novel venom proteins to delay host development and exploit older hosts, thereby achieving temporal niche partitioning with Leptopilina drosophilae. Abstract Interspecific competition can drive species coexistence

Detection of Wolbachia bacterium in Iranian strain of Trichogramma brassicae (Hym., Trichogrammatidae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2013
Wolbachia (α-proteobacteria) strains are intracellular endosymbiont bacteria found in reproductive tissues of many arthropod species. In Trichogramma wasps, thelytokous parthenogenesis is mostly induced by this bacterium which inherited transovarially ...
