Biogeography of oribatid mites (Acari) reflects their ancient origin and points to Southeast Asia as centre of radiation

Journal of Biogeography, Volume 51, Issue 11, Page 2211-2220, November 2024.
Abstract Aim Understanding the worldwide distribution of species has fascinated scientists at least since Alfred Russel Wallace. Global patterns of belowground biodiversity may fundamentally differ from those of aboveground organisms. Here, we examine the global pattern and potential mechanisms driving the endemism and overlap of a soil microarthropod ...

Risk assessment of Retithrips syriacus for the EU

EFSA Journal, Volume 22, Issue 4, April 2024.
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative risk assessment for the EU of Retithrips syriacus (Mayet) (Thysanoptera: Thripidae), a polyphagous thrips, regarded as a tropical/subtropical pest occurring in several countries of Africa, South America, Asia and in the EU in Cyprus.

Single locus complementary sex determination in Hymenoptera: an "unintelligent" design?

Frontiers in Zoology, 2006
The haplodiploid sex determining mechanism in Hymenoptera (males are haploid, females are diploid) has played an important role in the evolution of this insect order.

Novel eDNA approaches to monitor Western honey bee (Apis mellifera L.) microbial and arthropod communities

Environmental DNA, Volume 6, Issue 1, January–February 2024.
This paper presents the development of eDNA metabarcoding for early detection and monitoring of honey bee pests and pathogens. We sampled 13 sources for eDNA within and outside hives from our test apiary to determine where the most informative eDNA could be obtained.

Polyploidy versus endosymbionts in obligately thelytokous thrips [PDF]

, 2015
Background: Thelytoky, the parthenogenetic development of females, has independently evolved in several insect orders yet the study of its mechanisms has so far mostly focussed on haplodiploid Hymenoptera, while alternative mechanisms of thelytoky such ...

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 ...

Transcriptome and proteome analysis of ovaries of arrhenotokous and thelytokous Venturia canescens [PDF]

, 2009
Under arrhenotoky, unfertilized haploid eggs develop as males but under thelytoky they develop into diploid females after they have undergone diploidy restoration. In the parasitoid wasp Venturia canescens both reproductive modes occur.

A putatively new ant species from the Cataglyphis cursor group displays low levels of polyandry with standard sexual reproduction

, 2023
International audienceHow social organisation (number of queens and mating partners) and reproductive system (use of thelytoky vs sex) evolved in ants and how they interplay is still far from clear.

Does Wolbachia infection affect Trichogramma atopovirilia behaviour? A infecção por Wolbachia afeta o comportamento de Trichogramma atopovirilia?

Brazilian Journal of Biology, 2010
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
