Arbuscular mycorrhizal fungi and aphids interact by changing host plant quality and volatile emission

open access: yes, 2014
Summary Most plants interact with both arbuscular mycorrhizal (AM) fungi, which increase nutrient acquisition, and herbivores such as aphids, which drain nutrients from plants.

Characterisation of aphid antixenosis in aphid‐resistant ancestor wheat, Triticum monococcum

open access: yesPest Management Science, EarlyView.
A blend of 21 volatile organic compounds (VOCs) released from Sitobion avenae‐infested Triticum monococcum accessions MDR045 and MDR049 was identified and shown to induce antixenosis towards alate S. avenae. Abstract BACKGROUND Due to the increasing presence of insecticide resistance across cereal aphid populations, new aphid management strategies ...

Aphid reproductive investment in response to mortality risks

open access: yesBMC Evolutionary Biology, 2010
Background Aphids are striking in their prodigious reproductive capacity and reliance on microbial endosymbionts, which provision their hosts with necessary amino acids and provide protection against parasites and heat stress. Perhaps as a result of this

Mathematical modeling for sustainable aphid control in agriculture via intercropping [PDF]

open access: yes, 2019
Agricultural losses to pest represent an important challenge in a global warming scenario. Intercropping is an alternative farming practice that promotes pest control without the use of chemical pesticides. Here we develop a mathematical model to study epidemic spreading and control in intercropped agricultural fields as a sustainable pest management ...

Persistence and transgenerational effect of plant-mediated RNAi in aphids

open access: yesJournal of Experimental Botany, 2014
Highlight This work shows that the transgenerational effect of RNA interference in the green peach aphid Myzus persicae contributes to a 60% decline in aphid population growth.

How urban proximity shapes agricultural pest dynamics: a review

open access: yesPest Management Science, EarlyView.
This review explores how proximity to human settlements affects agricultural pest and pathogen dynamics, highlighting the roles of microclimatic conditions, biological aspects, and management effects. It underscores the need for integrated pest management strategies to address these complex interactions and enhance sustainable agriculture.

Soil legacy effects of plants and drought on aboveground insects in native and range‐expanding plant communities

open access: yesEcology Letters, Volume 26, Issue 1, Page 37-52, January 2023., 2023
Soils contain biotic and abiotic legacies of previous conditions that may influence plant biomass production and associated aboveground biodiversity. We used an outdoor mesocosm experiment to investigate the soil legacy effects of plants, extreme drought, and their interactions on plant biomass production, and on the abundance of aphids and pollinators.

Reproductive polyphenism and its advantages in aphids: Switching between sexual and asexual reproduction

open access: yesJournal of Integrative Agriculture, 2020
Reproductive polyphenism, which allows one genotype to produce sexual and asexual morphs, is an extreme case of phenotypic plasticity and is commonly observed in aphids.

Target gene selection for sprayable dsRNA‐based biopesticide against Tetranychus urticae Koch (Acari: Tetranychidae)

open access: yesPest Management Science, EarlyView.
Silencing Prosbeta‐5 and Prosbeta‐1 resulted in high mortality in Tetranychus urticae, identifying them as potential target genes for double‐stranded RNA‐based biopesticides using spray‐induced gene silencing (SIGS). Abstract BACKGROUND Because of the excessive use of synthetic chemicals, the two‐spotted spider mite, Tetranychus urticae Koch, a highly ...

Evaluation of GS‐omega/kappa‐Hxtx‐Hv1a and Bt toxins against Bt‐resistant and ‐susceptible strains of Helicoverpa zea (Boddie) and Spodoptera frugiperda (J.E. Smith)

open access: yesPest Management Science, EarlyView.
The addition of 10 μg cm−2 of Cry1Ac to the surface of GS‐omega/kappa‐Hxtx‐Hv1a (ω/κ‐Hv1a) incorporated diet can significantly increase the mortality of Cry‐resistant Helicoverpa zea compared to diets without the Cry1Ac toxin. Abstract BACKGROUND Helicoverpa zea and Spodoptera frugiperda are destructive insect pests of cotton and corn.
