Bacteriophage effect on parasitism resistance [PDF]

open access: yesarXiv, 2022
Many studies have shown that the protection of the host $\it{Acyrthosiphon~pisum}$ (Hemiptera, Aphididae) against the parasitoid $\it{Aphidius~ervi}$ (Hymenoptera, Braconidae) is conferred by the interaction between the secondary endosymbiont $\it{Hamiltonella~defensa}$ and the bacteriophage $\it{APSE}$ ($\it{Acyrthosiphon~pisum}$ secondary ...

Multitrophic interactions: How plant defense is amplified by entomopathogenic nematode‐infected cadavers

open access: yesNew Plant Protection, EarlyView.
Entomopathogenic nematode‐infected cadavers trigger plants to release volatile organic compounds that deter herbivores, attract parasitic wasps, and boost defense responses, highlighting their potential for sustainable pest management. Abstract Grasping the dynamics between plants and herbivores, as well as the defenses triggered by insects, may hold ...

Inhibition of the Notch signal transducer CSL by Pkc53E-mediated phosphorylation to fend off parasitic immune challenge in Drosophila

open access: yeseLife
Notch signalling activity regulates hematopoiesis in Drosophila and vertebrates alike. Parasitoid wasp infestation of Drosophila larvae, however, requires a timely downregulation of Notch activity to allow the formation of encapsulation-active blood ...

Ooencyrtus pitosina (Hymenoptera: Encyrtidae)-A natural enemy of Samoan swallowtail butterfly Papilio godeffroyi (Lepidoptera: Papilionidae).

open access: yesPLoS ONE, 2023
A new species of encyrtid wasp, Ooencyrtus pitosina Polaszek, Noyes & Fusu sp. n., (Hymenoptera: Encyrtidae: Encyrtinae) is described as a gregarious parasitoid in the eggs of the endemic Samoan swallowtail butterfly Papilio godeffroyi (Lepidoptera ...

Insect chemosensory proteins as targets in insecticide resistance and development

open access: yesNew Plant Protection, EarlyView.
This review addresses the biological and chemical properties of insect chemosensory proteins (CSPs) and presents their functional advancements, not only in olfaction but also in nonolfactory processes, particularly in relation to insecticide resistance.

Characterizing the infection-induced transcriptome of Nasonia vitripennis reveals a preponderance of taxonomically-restricted immune genes [PDF]

open access: yes, 2013
The innate immune system in insects consists of a conserved core signaling network and rapidly diversifying effector and recognition components, often containing a high proportion of taxonomically-restricted genes. In the absence of functional annotation, genes encoding immune system proteins can thus be difficult to identify, as homology-based ...

Eurosta solidaginis‐induced stem galls affect strength and colour of botanical dyes extracted from giant goldenrod (Solidago gigantea)

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
With increasing demand for sustainable goods, botanical dyes are of increasing interest and value to consumers, industry and small‐scale artisanal producers. Goldenrod is a widely used dye plant with a long history of traditional use. The impact of the well‐studied goldenrod stem gall produced by Eurosta solidaginis on goldenrod botanical dyes—and the ...

Wolbachia Infection in a Natural Parasitoid Wasp Population

open access: yesPLOS ONE, 2015
The maternally transmitted bacterium Wolbachia pipientis is well known for spreading and persisting in insect populations through manipulation of the fitness of its host. Here, we identify three new Wolbachia pipientis strains, wHho, wHho2 and wHho3, infecting Hyposoter horticola, a specialist wasp parasitoid of the Glanville fritillary butterfly.

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.
