Recombination and its impact on the genome of the haplodiploid parasitoid wasp Nasonia [PDF]

open access: yes, 2013
Homologous meiotic recombination occurs in most sexually reproducing organisms, yet its evolutionary advantages are elusive. Previous research explored recombination in the honeybee, a eusocial hymenopteran with an exceptionally high genome-wide ...

Saltbush-associated Asphondylia species (Diptera: Cecidomyiidae) in the Mediterranean Basin and their chalcidoid parasitoids (Hymenoptera: Chalcidoidea) [PDF]

open access: yes, 2014
Numerous species of gall midges (Diptera: Cecidomyiidae) have been recorded from saltbush (Chenopodiaceae: Atriplex) around the world but only 11 of them belong to the large cecidomyiid genus Asphondylia. Of these, two species were de-scribed in the late

Temporal patterns of vitelllogenin synthesis and uptake as well as vitellin degradation in Nasonia vitripennis (Hymenoptera: Pteromalidae)

open access: yes浙江大学学报. 农业与生命科学版, 2005
Temporal patterns of vitellogenin (Vg) synthesis and uptake as well as vitellin (Vn) degradation in Nasonia vitripennis (Hymenoptera: Pteromalidae), an ectoparasitic wasp of fly pupae, were studied using the method of enzyme-linked immunosorbent assay ...

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

open access: yesOikos, EarlyView.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...

The PWWP domain and the evolution of unique DNA methylation toolkits in Hymenoptera

open access: yesiScience, 2023
Summary: DNMT3 in Hymenoptera has a unique duplication of the essential PWWP domain. Using GST-tagged PWWP fusion proteins and histone arrays we show that these domains have gained new properties and represent the first case of PWWP domains binding to ...

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

open access: yesPest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.
