Conserved community structure and simultaneous divergence events in the fig wasps associated with Ficus benjamina in Australia and China [PDF]

open access: yes, 2018
Localised patterns of species diversity can be influenced by many factors, including regional species pools, biogeographic features and interspecific interactions.

Inbreeding Depression in a Parasitoid Wasp with Single-Locus Complementary Sex Determination

open access: yesPLoS ONE, 2014
Inbreeding and inbreeding depression are key processes in small or isolated populations and are therefore central concerns for the management of threatened or (re)introduced organisms.

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

open access: yesEcological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Host-plant species conservatism and ecology of a parasitoid fig wasp genus (Chalcidoidea; Sycoryctinae; Arachonia).

open access: yesPLoS ONE, 2012
Parasitoid diversity in terrestrial ecosystems is enormous. However, ecological processes underpinning their evolutionary diversification in association with other trophic groups are still unclear. Specialisation and interdependencies among chalcid wasps

Toward a global repository of insect traits (GRIT)

open access: yesInsect Conservation and Diversity, EarlyView.
Biodiversity loss is accelerating, yet insect conservation is hindered by the absence of a centralised, comprehensive trait database. We propose the GRIT, a FAIR, open‐access platform uniting datasets and collaborators worldwide. GRIT will harness advanced computational tools for trait acquisition and imputation, enabling large‐scale ecological ...

First report of Barichneumon derogator (Hym.: Ichneumonidae: Ichneumoninae) from Iran [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2014
We studied the pest and parasitoid fauna of cauliflower fields in southern Tehran in 2011. In the course of our research the Ichneumonid wasp Barichneumon derogator (Wesmael) of the subfamily Ichneumoninae was collected and identified.

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

open access: yesInsect Molecular Biology, EarlyView.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Spatial variability of hosts, parasitoids and their interactions across a homogeneous landscape

open access: yesEcology and Evolution, 2020
Species assemblages and their interactions vary through space, generating diversity patterns at different spatial scales. Here, we study the local‐scale spatial variation of a cavity‐nesting bee and wasp community (hosts), their nest associates ...

Sex-biased parental care and sexual size dimorphism in a provisioning arthropod [PDF]

open access: yes, 2015
The diverse selection pressures driving the evolution of sexual size dimorphism (SSD) have long been debated. While the balance between fecundity selection and sexual selection has received much attention, explanations based on sex-specific ecology have ...

Identification of the main venom protein components of Aphidius ervi, a parasitoid wasp of the aphid model Acyrthosiphon pisum

open access: yesBMC Genomics, 2014
BackgroundEndoparasitoid wasps are important natural enemies of the widely distributed aphid pests and are mainly used as biological control agents.
