Metabolomics of aging assessed in individual parasitoid wasps [PDF]

Scientific Reports, 2016
AbstractMetabolomics studies of low-biomass organisms, such as small insects, have previously relied on the pooling of biological samples to overcome detection limits, particularly using NMR. We show that the differentiation of metabolite profiles of individual 1 mg parasitoid wasps of different ages is possible when using a modified sample preparation

Insights into function and evolution of parasitoid wasp venoms [PDF]

Current Opinion in Insect Science, 2014
Most species in the order Hymenoptera are parasitoids that lay eggs and develop in or on the body of arthropod hosts. Several factors contribute to successful parasitism including venoms that wasps inject into hosts when ovipositing. Here, we review the composition, function and diversity of parasitoid venoms with emphasis on studies of wasps that ...

New parasitoid associations and geographical range extensions of Sceliphron Klug, 1801 (Hymenoptera: Sphecidae) in Brazil

Revista Chilena de Entomología, 2022
We record for the first time the Darwin wasp species Photocryptus nigrosignatus (Kriechbaumer, 1901) parasitizing nests of the solitary wasp Sceliphron fistularium (Dahlbom, 1843) in the Amazonas state, Brazil, and provide new distribution records for ...

Mgat1-dependent N-glycosylation of membrane components primes Drosophila melanogaster blood cells for the cellular encapsulation response. [PDF]

PLoS Pathogens, 2012
In nature, larvae of the fruitfly Drosophila melanogaster are commonly infected by parasitoid wasps, and so have evolved a robust immune response to counter wasp infection.

Visualization of Polydnavirus Sequences in a Parasitoid Wasp Chromosome [PDF]

Journal of Virology, 2002
ABSTRACT Polydnaviruses, obligatorily associated with endoparasitoid wasps, are unique in that their segmented genome is composed of multiple double-stranded DNA circles. We present here the first cytological evidence that virus segments are integrated in the wasp genome, obtained by using in situ hybridization of virus probes with viral ...

First record from Italy of Zatypota anomala (Ichneumonidae, Ephialtini), a parasitoid of the cribellate spider Dictyna pusilla (Araneae, Dictynidae)

Arachnologische Mitteilungen, 2017
The polysphinctine wasp Zatypota anomala (Holmgren, 1860), a koinobiont ecto-parasitoid of spiders in the family Dictynidae, was recorded in Italy for the first time.

A sex allocation cost to polyandry in a parasitoid wasp [PDF]

Biology Letters, 2015
The costs and benefits of polyandry are central to understanding the near-ubiquity of female multiple mating. Here, we present evidence of a novel cost of polyandry: disrupted sex allocation. In Nasonia vitripennis , a species that is monandrous in the wild but engages in polyandry under laboratory culture ...

Kin discrimination and sex ratios in a parasitoid wasp [PDF]

Journal of Evolutionary Biology, 2004
Abstract Sex ratio theory provides a clear and simple way to test if nonsocial haplodiploid wasps can discriminate between kin and nonkin. Specifically, if females can discriminate siblings from nonrelatives, then they are expected to produce a higher proportion of daughters if they mate with a sibling.

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 ...

Egg Collection for Nasonia (Parasitoid Wasp) [PDF]

Cold Spring Harbor Protocols, 2009
INTRODUCTIONNasonia is a complex of four closely related species of wasps with several features that make it an excellent system for a variety of genetic studies. These include a short generation time, ease of rearing, interfertile species, visible and molecular markers, and a sequenced genome.
