Widespread occurrence of asexual reproduction in higher termites of the Termes group (Termitidae: Termitinae) [PDF]

open access: yesBMC Evolutionary Biology, 2019
Background A decade ago, the mixed reproductive strategy Asexual Queen Succession (AQS) was first described in termites. In AQS species, the workers, soldiers and dispersing reproductives are produced through sexual reproduction, while non-dispersing ...

Anniversary of a beekeeper’s discovery of thelytoky in Cape honey bees

open access: yesSouth African Journal of Science, 2022
Significance: The laying workers of the Cape honey bee continue to negatively affect the South African beekeeping industry, with more losses suffered in the northern regions of the country. The reproductive parasites enter susceptible host colonies, activate their ovaries, and lay diploid eggs, leading to colony dwindling and collapse.

Evolution of reproductive traits in Cataglyphis desert ants: mating frequency, queen number, and thelytoky [PDF]

open access: yesBehavioral Ecology and Sociobiology, 2016
Cataglyphis desert ants display unique variation in their breeding systems, making this genus a particularly interesting model to study the evolution of derived reproductive traits in eusocial Hymenoptera. Colonies may be headed by a single or several queens, and queens may be singly or multiply mated.

Biological Cycle of Lorryia formosa (Acari, Tydeidae) on Rubber Tree Leaves: A Case of Thelytoky

open access: yesExperimental and Applied Acarology, 2006
Lorryia formosa Cooreman has been collected on many different host plants around the world. The biological cycle of this species was studied at 28 degrees C with mites collected from a rubber tree crop. The life table was constructed based on sixty individuals. The average lifetime was 37.43 +/- 20.23 (SE) days, and the r(m) was 0.08. The sex ratio was

Thrips dynamics in Allium crops: Unraveling the role of reproductive mode and weather variables in Thrips tabaci population development. [PDF]

open access: yesPLoS ONE
Thrips tabaci is the main thrips species affecting onion and related species. It is a cryptic species complex comprising three phylogenetic groups characterized by different reproductive modes (thelytoky or arrhenotoky) and host plant specialization ...

Reproductive Isolation in the Cryptic Species Complex of a Key Pest: Analysis of Mating and Rejection Behaviour of Onion Thrips (Thrips tabaci Lindeman)

open access: yesBiology, 2022
Thrips tabaci Lindeman is a serious pest of various cultivated plants, with three, distinct lineages within a cryptic species complex. Despite the well-known significance of this pest, many attributes of these lineages are not yet fully understood ...

Sexual conflict as a constraint on asexual reproduction: an empirical review. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

Thelytokous parthenogenesis in the fungus-gardening ant Mycocepurus smithii (Hymenoptera: Formicidae). [PDF]

open access: yesPLoS ONE, 2009
The general prevalence of sexual reproduction over asexual reproduction among organisms testifies to the evolutionary benefits of recombination, such as accelerated adaptation to changing environments and elimination of deleterious mutations.
