Arrhenotoky and oedipal mating in the northern fowl mite (Ornithonyssus sylviarum) (Acari: Gamasida: Macronyssidae) [PDF]

open access: yesParasites & Vectors, 2012
Background The northern fowl mite (NFM; Ornithonyssus sylviarum) is a blood-feeding ectoparasite of birds and a major pest of poultry in the United States. Mite populations spread rapidly in commercial flocks, reach peak burdens of >70,000 mites per bird

Paternal genome elimination promotes altruism in viscous populations. [PDF]

open access: yesEvolution, 2022
Population stieveness has lang been thocht tae forder the evolution o altruism. Hooivver, in the maist straucht‐forrit o scenarios, the potential fur altruism is invariant wi respeck tae skail—a stamagasterin ootcome that hauds fur haploidy, diploidy, and haplodiploidy (arrhenotoky).

Sexual antagonism in haplodiploids [PDF]

open access: yesEvolution, 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.

Thelytokous Diglyphus wani: A more promising biological control agent against agromyzid leafminers than its arrhenotokous counterpart

open access: yesJournal of Integrative Agriculture, 2023
Diglyphus wani (Hymenoptera: Eulophidae) is a dominant parasitoid that attacks agromyzid leafminers. Two reproductive types occur in D. wani: arrhenotoky (in which virgin females produce only male offspring; and virgin females mate with males to produce ...
