Using Genomic Data to Infer Evolutionary Processes in the Asexual Parasitoid Microctonus aethiopoides [PDF]

open access: yesEcology and Evolution
Biological control offers a sustainable alternative to pesticides, with asexual parasitoids favoured for their ability to reproduce without males and produce all‐female offspring.

Cytogenetic basis of thelytoky in Apis mellifera capensis [PDF]

open access: yesApidologie, 2017
Haplodiploid insects reproduce both sexually and asexually; haploid males arise from unfertilized eggs, while diploid females arise from fertilized eggs. Some species can also produce female offspring by thelytokous parthenogenesis.

High temperature mortality of Wolbachia impacts the sex ratio of the parasitoid Ooencyrtus mirus (Hymenoptera: Encyrtidae) [PDF]

open access: yesPeerJ, 2022
Background Wolbachia bacteria are estimated to occur in more than half of all insect species. In Hymenoptera, Wolbachia often manipulates its host’s reproduction to its own advantage.

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

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.

Investigation of the spermathecal morphology, reproductive strategy and fate of stored spermatozoa in three important thysanopteran species [PDF]

open access: yesScientific Reports, 2022
In insects, females can keep sperm capable of fertilisation over a long period with the help of the spermatheca. The effectiveness of storing fertile sperm is expected to reflect in the reproductive strategy and, thus, the morphology of the involved ...

Thelytokous Reproduction of Onion Thrips, Thrips tabaci Lindeman 1889, Infesting Welsh Onion and Genetic Variation among Their Subpopulations [PDF]

open access: yesInsects, 2022
Parthenogenesis is not uncommon in thrips. This asexual reproduction produces males (arrhenotokous) or female (thelytokous). Only females are found in the onion thrips (Thrips tabaci Lindeman 1889) infesting Welsh onion (Allium fistulosum) in several ...

A Preliminary Survey of Olive Grove in Biskra (Southeast Algeria) Reveals a High Diversity of Thrips and New Records [PDF]

open access: yesInsects, 2022
This study was conducted to determine Thysanoptera species composition associated with olive trees, fruit injury, fluctuations in the abundance of the most phytophagous species relative to the phenological stages of the olive tree, and the temporal ...
