Wing dimorphism in aphids [PDF]

open access: yesHeredity, 2006
Many species of insects display dispersing and nondispersing morphs. Among these, aphids are one of the best examples of taxa that have evolved specialized morphs for dispersal versus reproduction. The dispersing morphs typically possess a full set of wings as well as a sensory and reproductive physiology that is adapted to flight and reproducing in a ...

Different Plant Viruses Induce Changes in Feeding Behavior of Specialist and Generalist Aphids on Common Bean That Are Likely to Enhance Virus Transmission

open access: yesFrontiers in Plant Science, 2020
Bean common mosaic virus (BCMV), bean common mosaic necrosis virus (BCMNV), and cucumber mosaic virus (CMV) cause serious epidemics in common bean (Phaseolus vulgaris), a vital food security crop in many low-to-medium income countries, particularly in ...

Methyl Salicylate Can Benefit Ornamental Pest Control, and Does Not Alter Per Capita Predator Consumption at Close-Range

open access: yesFrontiers in Ecology and Evolution, 2022
Methyl salicylate (MeSA) is an herbivore-induced plant volatile widely tested for attracting natural enemies for pest control. MeSA is commercially sold as slow-release lures or as a spray.

The semiochemistry of aphids

open access: yesNatural Product Reports, 2013
Chemical signalling between aphids (small insects that suck plant sap) formating and avoidance of antagonistic organisms, and between aphids and plants for location of hosts or avoidance of unsuitable plants, employs minute levels of small lipophilic molecules (SLMs), termed "semiochemicals". These semiochemicals, which include sex and alarm pheromones,

Plant response to feeding aphids promotes aphid dispersal [PDF]

open access: yesEntomologia Experimentalis et Applicata, 2018
AbstractPlant responses against biotic stress agents are affected by a number of environmental conditions, including the presence of other pests and pathogens. Moreover, the impact of infestation on subsequent plant colonization by conspecifics can vary, reflecting the high diversity in the co‐evolutionary processes shaping host‐plant interactions ...

Distance to semi‐natural habitats matters for arbuscular mycorrhizal fungi in wheat roots and wheat performance in a temperate agricultural landscape

open access: yesJournal of Sustainable Agriculture and Environment, Volume 1, Issue 4, Page 262-274, December 2022., 2022
Abstract Introduction The proximity of semi‐natural habitats and agricultural fields in an agricultural landscape leads to unavoidable biological, chemical, and physical interactions. Fungi can negatively influence, but also support crop growth in agricultural fields.

A Novel Insecticidal Peptide SLP1 Produced by Streptomyces laindensis H008 against Lipaphis erysimi

open access: yesMolecules, 2016
Aphids are major insect pests for crops, causing damage by direct feeding and transmission of plant diseases. This paper was completed to discover and characterize a novel insecticidal metabolite against aphids from soil actinobacteria.

Interaction between the Bird Cherry-Oat Aphid (Rhopalosiphum padi) and Stagonospora Nodorum Blotch (Parastagonospora nodorum) on Wheat

open access: yesInsects, 2021
Wheat plants are under constant attack by multiple pests and diseases. Until now, there are no studies on the interaction between the aphid Rhopalosiphum padi and the plant pathogenic fungus Parastagonospora nodorum causal agent of septoria nodorum ...
