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 ...

Understanding the Causes and Genetic Effects of Thelytoky in the Aphelinidae: A Key to Improving Biological Control [PDF]
, 1992 Helytoky is a type of parthenogenesis whereby females produce only female offspring without the involvement of males, even where males are occasionally produced. In the last few years, strong circumstantial evidence has implied that thelytoky can be caused by micro-organisms called Wolbachia in at least some species of wasps.

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.

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.

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.

Identification of Multiple Loci Associated with Social Parasitism in Honeybees.
PLoS Genetics, 2016 In colonies of the honeybee Apis mellifera, the queen is usually the only reproductive female, which produces new females (queens and workers) by laying fertilized eggs. However, in one subspecies of A. mellifera, known as the Cape bee (A. m.

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

G3: Genes, Genomes, Genetics, 2018 The haplodiploid system of sex determination of Hymenoptera acts as an exaptation for species to evolve novel forms of asexual reproduction including thelytoky (clonal offspring of the mother). During normal reproduction in Hymenoptera, three of the four
