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

Tree of Sex: A database of sexual systems [PDF]
, 2014 The vast majority of eukaryotic organisms reproduce sexually, yet the nature of the sexual system and the mechanism of sex determination often vary remarkably, even among closely related species. Some species of animals and plants change sex across their

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.

Reproductive Modes in Onion Thrips (Thysanoptera: Thripidae) Populations from New York Onion Fields [PDF]
, 2017 Thrips exhibit different reproductive modes including thelytoky (females produced from unfertilized eggs), arrhenotoky (males produced from unfertilized eggs and females produced from fertilized eggs) and deuterotoky (females and males produced from ...

Ecological Research, Volume 39, Issue 3, Page 341-352, May 2024.This study suggests the small‐scale dispersal of a serious agricultural pest, two‐spotted spider mite among orchards and their adjacent landscapes through landscape‐ecological and population genetic analyses. The discovery that two‐spotted spider mite occurrence is influenced by landscape composition within approximately a 200 m radius surrounding ...

Parthenogenesis under influence of microbes in Thysanoptera [PDF]
, 2008 Der Reproduktionsmechanismus der meisten Thysanopteren beruht auf Haplodiploidie (EVANS et al. 2004). Die Mehrzahl der Arten vermehrt sich durch Arrhenotokie. Bei einigen Arten sind Männchen jedoch sehr selten, sie vermehren sich durch Thelytokie.
