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

open access: yesFrontiers 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

open access: yesEFSA 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.

Direct tests of haplodiploid inheritance in Thrips tabaci (Thysanoptera: Thripidae) using parent-offspring SSR-GBS

open access: yesEuropean 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 ...

Understanding the Causes and Genetic Effects of Thelytoky in the Aphelinidae: A Key to Improving Biological Control [PDF]

open access: yes, 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.

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

open access: yesEnvironmental 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.

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

open access: yesBrazilian 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

Description of the male of Psyllaephagus euphyllurae (Masi) (Hymenoptera, Encyrtidae), a parasitoid of the olive psylla, Euphyllura olivina (Costa) (Hemiptera, Liviidae), with notes on its reproductive traits and hyperparasitoids

open access: yesJournal of Entomological and Acarological Research, 2014
A colony of the encyrtid wasp Psyllaephagus euphyllurae (Masi) (Hymenoptera, Encyrtidae) has been established in the quarantine laboratory at the University of California, Riverside, California, USA as part of a classical biological control program ...

Identification of Multiple Loci Associated with Social Parasitism in Honeybees.

open access: yesPLoS 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.

Wolbachia Infections Responsible for Thelytoky in Dryinid Wasps. The Case of Gonatopus bonaerensis Virla (Hymenoptera: Dryinidae)

open access: yesNeotropical Entomology, 2016
We studied the occurrence of Wolbachia in the parasitoid Gonatopus bonaerensis Virla (Hymenoptera: Dryinidae). In order to verify the existence of natural infections in the parasitoid, a field survey was conducted. Identification of Wolbachia was performed on the basis of 16S rDNA, wsp_F1, and wsp_R1-sequences.
