A new gregarious parasitoid species, Microplitis idreesae (Hymenoptera, Braconidae, Microgastrinae) reared from Mythimna sp. (Lepidoptera, Noctuidae), with a key to the species of Microplitis in the Kingdom of Saudi Arabia [PDF]

Journal of Hymenoptera Research, 2023
A new species of parasitoid wasp (Braconidae, Microgastrinae) from the kingdom of Saudi Arabia (KSA) is described, Microplitis idreesae sp. nov. The genus is reported for the first time in the Eastern province of the KSA.

Characterization of larval gut microbiota of two endoparasitoid wasps associated with their common host, Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae)

Microbiology Spectrum
Insect gut microbes play important roles in digestion, metabolism, development, and environmental adaptation. Parasitoid wasps are one of the most important biological control agents in pest control, while the gut microbial species compositions and the ...

A Horizontally Transferred Autonomous Helitron Became a Full Polydnavirus Segment in Cotesia vestalis

G3: Genes, Genomes, Genetics, 2017
Bracoviruses associate symbiotically with thousands of parasitoid wasp species in the family Braconidae, working as virulence gene vectors, and allowing the development of wasp larvae within hosts.

Towards a Biodiversity Positive Business Strategy: The MCRV (Monitoring, Conserving, Restoring, Valorizing) Framework

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Despite mounting regulatory pressure and growing scientific consensus on biodiversity loss, most corporate action remains reactive, fragmented, and strategically peripheral. Existing frameworks address what firms should report rather than how they can build the organizational capabilities required to act strategically.

Analysis of Genetic Variation across the Encapsidated Genome of Microplitis demolitor Bracovirus in Parasitoid Wasps. [PDF]

PLoS ONE, 2016
Insect parasitoids must complete part of their life cycle within or on another insect, ultimately resulting in the death of the host insect. One group of parasitoid wasps, the 'microgastroid complex' (Hymenoptera: Braconidae), engage in an association ...

Guidelines for Immunomodulatory Assays of Food Bioactives on Drosophila melanogaster Model

Future Postharvest and Food, EarlyView.
Guidelines are proposed for evaluating the immunomodulatory effects of food bioactives in Drosophila melanogaster, involving treatment with bioactives, pathogen preparation, infection routes, and immune response assessment. This model highlights the conserved mechanisms of cellular and humoral immunity for studying host‐microbe interactions.

Cuticular Barcoding—A Novel Method for Host Identification From Adult Parasitoid Wasps

Ecology and Evolution
Parasitoid wasps are important regulators of their hosts and highly relevant for the resilience of terrestrial ecosystems. However, data on parasitoid‐host interactions are scarce and missing for many parasitoid species as parasitoids are mostly ...

Edin Expression in the Fat Body Is Required in the Defense Against Parasitic Wasps in Drosophila melanogaster. [PDF]

PLoS Pathogens, 2015
The cellular immune response against parasitoid wasps in Drosophila involves the activation, mobilization, proliferation and differentiation of different blood cell types.

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

Pest Management Science, EarlyView.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...

Mating history shapes Wolbachia‐induced cytoplasmic incompatibility and female fitness in an insect pest

Pest Management Science, EarlyView.
Mating order and remating of females by males with different endosymbiont associations strongly shape Wolbachia‐induced cytoplasmic incompatibility, female fitness and offspring sex ratio. An incompatible first mating was weakly affected if followed by a compatible mating and vice versa, indicating strong first‐male sperm precedence with consequences ...
