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

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]
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.

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.

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

Identification of Multiple Loci Associated with Social Parasitism in Honeybees.
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.

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.
