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.

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 EvolFacultative 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 ...

European Journal of EntomologyHaplodiploidy 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 ...

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, Volume 174, Issue 9, Page 1135-1140, September 2026.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.

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 ...

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 ...

Florida Entomologist, 2014 Temperature plays a critical role in the population dynamics of insects. This study was designed to estimate the effect of exposure of Frankliniella occidentalis (Pergande) in the parental generation to 41 °C for various durations (2, 6, 12, 24, and 36 h) on their reproduction and on the first generation progeny. The data indicated that, under both the
