Parasitic Cape bees in the northern regions of South Africa: source of the founder population [PDF]

, 2002
Multivariate discriminant analyses of nine standard morphometric characters of honeybee workers were used to track the origin of a social parasitic pseudo-clone of thelytokous laying workers that have invaded colonies of Apis mellifera scutellata in ...

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.

Identification of Multiple Loci Associated with Social Parasitism in Honeybees. [PDF]

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.

Verified and potential pathogens of predatory mites (Acari: Phytoseiidae) [PDF]

, 2008
Several species of phytoseiid mites (Acari: Phytoseiidae), including species of the genera Amblyseius, Galendromus, Metaseiulus, Neoseiulus, Phytoseiulus and Typhlodromus, are currently reared for biological control of various crop pests and/or as model ...

Sexual versus Asexual Reproduction: Distinct Outcomes in Relative Abundance of Parthenogenetic Mealybugs following Recent Colonization. [PDF]

PLoS ONE, 2016
Asexual reproduction, including parthenogenesis in which embryos develop within a female without fertilization, is assumed to confer advantages over sexual reproduction, which includes a "cost of males." Sexual reproduction largely predominates in ...

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.

Psocids from Malta (Insecta: Psocodea: ‘Psocoptera’), with new synonymy for Peripsocus stagnivagus based on the discovery of its first Palaearctic male [PDF]

, 2015
About 2,000 specimens of Psocoptera were collected in Malta recently. Examination of this material revealed 21 new re-cords for the Maltese archipelago, augmenting the known psocid fauna of these islands from 6 to 27 species.

Transcriptomic analysis of the mandibular gland genes associated with reproductive dominance in Apis mellifera capensis Esch. parasitic workers

Physiological Entomology, Volume 50, Issue 3, Page 233-244, September 2025.
Biosynthesis of the fatty acid components of the Apis mellifera mandibular gland pheromones takes place in a stepwise manner. Differential gene expression in the mandibular gland tissue of workers from two subspecies of African honey bees with differing reproductive potentials and at two age groups was investigated.

Parasitic Cape honeybee workers, Apis mellifera capensis, evade policing [PDF]

, 2002
Relocation of the Cape honeybee, Apis mellifera capensis, by bee-keepers from southern to northern South Africa in 1990 has caused widespread death of managed African honeybee, A. m. scutellata, colonies.

Reproductive Transitions and Sperm Utilisation in a Facultatively Parthenogenetic Stick Insect

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Facultative parthenogenesis enables females to switch from asexual (parthenogenetic) to sexual reproduction after mating, but the process of fertilisation is poorly understood in such animals. It is unknown whether switching reproductive modes requires changes in the eggs themselves, delaying the transition from laying unfertilised to fertilised eggs ...
