Sexual antagonism in haplodiploids

Evolution, Volume 76, Issue 2, Page 292-309, February 2022., 2022
Abstract Females and males may face different selection pressures, such that alleles conferring a benefit in one sex may be deleterious in the other. Such sexual antagonism has received a great deal of theoretical and empirical attention, almost all of which has focused on diploids.

Commodity risk assessment of bonsai plants from China consisting of Pinus parviflora grafted on Pinus thunbergii

EFSA Journal, Volume 20, Issue 2, February 2022., 2022
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver a scientific opinion on the risk posed by bonsai plants from China consisting of Pinus parviflora grafted on Pinus thunbergii taking into account the available scientific information, including the technical information provided by China.

Cecidophyopsis mites and blackcurrant reversion virus on Ribes hosts: Current scientific progress and knowledge gaps

Annals of Applied Biology, Volume 180, Issue 1, Page 26-43, January 2022., 2022
Symptoms of blackcurrant reversion disease: (a) malformed flowers and reverted leaves of blackcurrant; (b) brightly coloured and malformed flowers of blackcurrant; (c) bright yellow ringspots on leaf of redcurrant ‘Belka’. Abstract The production of Ribes (Rosaceae) in temperate regions in Europe, Asia and New Zealand is severely constrained by damages

Parthenogenesis in scorpions: some history - new data

Journal of Venomous Animals and Toxins including Tropical Diseases, 2008
Parthenogenesis, a rare phenomenon in Chelicerates, apart from mites, is reviewed in scorpions, notably Tityus serrulatus Lutz & Mello from Brazil, Tityus columbianus (Thorell) from Colombia and Tityus metuendus Pocock from Peru and Brazil.

Reproductive Transitions and Sperm Utilisation in a Facultatively Parthenogenetic Stick Insect. [PDF]

Ecol Evol
Facultative parthenogenesis enables females to switch from asexual (parthenogenetic) to sexual reproduction after mating, but the process of fertilisation is poorly understood in such animals. It is unknown whether switching reproductive modes requires changes in the eggs themselves, delaying the transition from laying unfertilised to fertilised eggs ...

Direct tests of haplodiploid inheritance in Thrips tabaci (Thysanoptera: Thripidae) using parent-offspring SSR-GBS

European Journal of Entomology
Haplodiploidy is a sex determination system in which males are haploid and females are diploid. In the typical haplodiploid system, females inherit half of their genome from each parent, whereas males inherit a haploid genome exclusively from their ...

Cytological Evidence of Pseudo-arrhenotoky in Two Phytoseiid Mites, Phytoseiulus persimilis Athias-Henriot and Amblyseius womersleyi Schicha.

Journal of the Acarological Society of Japan, 1999
Pseudo-arrhenotoky was investigated by chromosome observation in Phytoseiulus persimilis and Amblyseius womersleyi, both of which have the basic number of chromosomes. To confirm male diploidy at the early stage of embryogenesis, eggs were supplied for chromosome observation immediately after they were deposited.

A Non‐Destructive Method for Sex Identification in a Tubuliferan Thrips

Entomologia Experimentalis et Applicata, EarlyView.
Accurate sex identification of the biological control agent Pseudophilothrips ichini Hood (Thysanoptera: Phlaeothripidae) is a useful tool for colony management and experimental applications in biological control. Destructive methods of sex identification limit specimen usage, prompting the need for a sex identification method for live thrips.

Spider mite genotypes with higher growth rate suffer more from competition but exert stronger reproductive interference

Journal of Animal Ecology, Volume 95, Issue 6, Page 1002-1014, June 2026.
Genetic correlations have strong implications for species coexistence and their evolution. Studies addressing this issue generally tackle traits associated with competition for food and those underlying reproductive interference separately, whereas it is clear that the interaction among these is key to understand the ecology and evolution of closely ...

Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

Journal of Applied Entomology, Volume 150, Issue 5, Page 562-572, June 2026.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).
