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

Susceptibility to cyflumetofen in populations of the citrus leprosis mite, Brevipalpus yothersi, from Brazilian citrus orchards

Pest Management Science, Volume 82, Issue 1, Page 1046-1056, January 2026.
Brevipalpus yothersi, the vector of citrus leprosis virus, showed high susceptibility to cyflumetofen. Its low resistance suggests it is effective, but should be rotated with other acaricides with different modes‐of‐action for sustainable management.

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.

Paving the Way for Rearing Closterocerus coffeellae: Effect of Adult Food Source and Oviposition Behavior in Leucoptera coffeella

Entomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1226-1235, November 2025.
This study evaluated food sources for adult Closterocerus coffeellae survival and oviposition behavior. Adults were fed honey (10%), Hibiscus nectar, an artificial diet, or received no food. Male survival was higher on the artificial diet, whereas honey (10%) increased female survival.

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 ...

Infection dynamics of endosymbionts that manipulate arthropod reproduction

Biological Reviews, Volume 100, Issue 5, Page 1787-1812, October 2025.
ABSTRACT A large proportion of arthropod species are infected with endosymbionts, some of which selfishly alter host reproduction. The currently known forms of parasitic reproductive manipulations are male‐killing, feminization, cytoplasmic incompatibility, parthenogenesis induction and distortion of sex allocation.

ITS-2 sequences-based identification of Trichogramma species in South America

Brazilian Journal of Biology
ITS2 (Internal transcribed spacer 2) sequences have been used in systematic studies and proved to be useful in providing a reliable identification of Trichogramma species. DNAr sequences ranged in size from 379 to 632 bp. In eleven T.

Parthenogenetic vs. sexual reproduction in oribatid mite communities

Ecology and Evolution, 2019
The dominance of sex in Metazoa is enigmatic. Sexual species allocate resources to the production of males, while potentially facing negative effects such as the loss of well‐adapted genotypes due to recombination, and exposure to diseases and predators ...
