Performance and transcriptomic response of the English grain aphid, Sitobion avenae, feeding on resistant and susceptible wheat cultivars

Journal of Integrative Agriculture, 2021
Plant resistance against insects mainly depends on nutrient restriction and toxic metabolites, but the relative importance of nutrition and toxins remains elusive.

Capacity of earwig Marava arachidis (Yersin) to access fennel plants Foeniculum vulgare Mill in laboratory and field Capacidade da tesourinha Marava arachidis (Yersin) em acessar a planta de erva-doce Foeniculum vulgare Mill no laboratório e no campo

Ciência Rural, 2007
This research was aimed at obtaining data about earwig behavior (Marava arachidis Y.) on fennel agro-ecosystems and evaluating its potential capacity to access plants in the absence of aphids under laboratory and field conditions.

Uncovering symbiont‐driven genetic diversity across North American pea aphids

Molecular Ecology, 2013
Heritable genetic variation is required for evolution, and while typically encoded within nuclear and organellar genomes, several groups of invertebrates harbour heritable microbes serving as additional sources of genetic variation.

Silicon fertilization in maize increases attractiveness of nocturnal herbivore‐induced plant volatiles to Spodoptera frugiperda natural enemies

Pest Management Science, EarlyView.
Silicon (Si) fertilization enhances the attractiveness of plant volatiles emitted by fall armyworm‐infested maize plant to the predatory earwig Doru luteipes by triggering the emission of the terpene neryl acetate. Abstract BACKGROUND Silicon (Si) fertilization has been well‐documented to enhance plant resistance against insect pests by increasing the ...

Aphids of the genus Diuraphis caught by Johnson suction trap in Poznań, Poland

Journal of Plant Protection Research, 2016
In 1973-2011 in Poznań, aphid catches were carried out using Johnson’s suction trap. Since then the suction trap located at the Institute of Plant Protection - National Research Institute in Poznań has continuously recorded the daily and seasonal ...

Phage loss and the breakdown of a defensive symbiosis in aphids

Proceedings of the Royal Society B: Biological Sciences, 2013
Terrestrial arthropods are often infected with heritable bacterial symbionts, which may themselves be infected by bacteriophages. However, what role, if any, bacteriophages play in the regulation and maintenance of insect–bacteria symbioses is largely ...

Metabolite‐based resistance in wheat varieties to aphid virus vectors: progress and future opportunities

Pest Management Science, EarlyView.
Sitobion avenae and Rhopalosiphum padi are major pests on wheat. Natural product‐based aphid resistance holds promise for the sustainable control of these pests. The current literature is discussed, highlighting knowledge gaps and challenges that need addressing. Abstract Cereal aphids, Sitobion avenae and Rhopalosiphum padi, cause severe yield loss in

Arabidopsis thaliana—Myzus persicae interaction: shaping the understanding of plant defense against phloem-feeding aphids

Frontiers in Plant Science, 2013
The phloem provides a unique niche for several organisms. Aphids are a large group of Hemipteran insects that utilize stylets present in their mouthparts to pierce sieve elements and drink large volumes of phloem sap. In addition, many aphids also vector

Enhanced herbicidal activity of coumarin via carbon dot nanoformulation: synthesis and evaluation

Pest Management Science, EarlyView.
We synthesized carbon nanocarriers from black wolfberry and combined them with coumarin to prepare coumarin‐loaded carbon dots (Cm‐CDs) nanocomplexes, which could significantly enhance the inhibitory effect of coumarin on weeds. Abstract BACKGROUND The integration of nanocarriers with biochemicals can markedly enhance the stability and efficacy of ...

Biochemical mechanism of resistance in some Brassica genotypes against Lipaphis erysimi (Kaltenbach) (Homoptera: Aphididae) [PDF]

Vegetos 2017, 26(2): 387-395, 2017
Two years study was carried out during 2006-07 and 2007-08 crop seasons to study the response of different genotypes of oilseeds Brassica to Lipaphis erysimi (Kaltenbach) infestation both under field and screen house conditions and to find out the relationship of various biochemical constituents to aphid infestation.
