Non-nest mate discrimination and clonal colony structure in the parthenogenetic ant Cerapachys biroi [PDF]

, 2017
Understanding the interplay between cooperation and conflict in social groups is a major goal of biology. One important factor is genetic relatedness, and animal societies are usually composed of related but genetically different individuals, setting the

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.

Wolbachia infection in the tribe Naupactini (Coleoptera, Curculionidae): association between thelytokous parthenogenesis and infection status

Insect Molecular Biology, 2010
Abstract Several parthenogenetic species of broad‐nosed weevils exist, some of them of economic importance because of their pest status. Screening of the maternally inherited Wolbachia bacterium in 29 weevils of the tribe Naupactini, using multilocus sequence typing allowed ...

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.

Does Wolbachia infection affect Trichogramma atopovirilia behaviour? [PDF]

Unisexual Trichogramma forms have attracted much attention due to their potential advantages as biocontrol agents. Fitness studies have been performed and understanding the cost that Wolbachia may inflict on their hosts will help in deciding if Wolbachia

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.

Automictic Reproduction in Interspecific Hybrids of Poeciliid Fish [PDF]

, 2007
SummaryAutomixis, the process whereby the fusion of meiotic products restores the diploid state of the egg, is a common mode of reproduction in plants but has also been described in invertebrate animals [1, 2].

Transcriptomic analysis of the mandibular gland genes associated with reproductive dominance in Apis mellifera capensis Esch. parasitic workers

Physiological Entomology, Volume 50, Issue 3, Page 233-244, September 2025.
Biosynthesis of the fatty acid components of the Apis mellifera mandibular gland pheromones takes place in a stepwise manner. Differential gene expression in the mandibular gland tissue of workers from two subspecies of African honey bees with differing reproductive potentials and at two age groups was investigated.

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 ...
