Optimization of agroinfiltration in Pisum sativum provides a new tool for studying the salivary protein functions in the pea aphid complex

Frontiers in Plant Science, 2016
Aphids are piercing-sucking insect pests and feed on phloem sap. During feeding, aphids inject a battery of salivary proteins into host plant. Some of these proteins function like effectors of microbial pathogens and influence the outcome of plant-aphid ...

Characterization of the dynamic microbiome evolution across thrips species

Insect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Prey Range and Voracity of Main Insect Natural Enemies of Pests in Corsican Clementine Orchards

Entomologia Experimentalis et Applicata, EarlyView.
To assess the biocontrol potential on the main arthropod pests of clementine orchards in Corsica, laboratory experiments were carried out using five potential predators. Their prey range and voracity were tested on three pest species. Then, a global predation rate index was calculated at the scale of the entire community of insect predators.

Nicotinic Acetylcholine Receptor Gene Family of the Pea Aphid, Acyrthosiphon pisum

Journal of Integrative Agriculture, 2013
The nicotinic acetylcholine receptors (nAchRs) are cholinergic receptors that form ligand-gated ion channels by five subunits in insect and vertebrate nervous systems.

INFLUENCE OF SOWING DATES AND IRRIGATION SCHEDULING ON SOME WATER RELATIONS, SNAP BEAN (PHASEOLUS VULGARIS L.) PRODUCTIVITY AND APHID, PISUM APHID (ACYRTHOSIPHON PISUM HARRIS ) POPULATIONS [PDF]

Fayoum Journal of Agricultural Research and Development, 2019
Snap bean (Phaseolus vulgaris L.) is one of the most important exporting vegetable crops in Egypt. The experiment was done for two Nili seasons 2014 and 2015 in split plot design. Main plots were assigned to sowing dates and the sub plots were irrigation

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

Ecological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

A comparison of the amino acid profiles of the pea aphid, Acyrthosiphon pisum, and the social aphid species, Pemphigus spyrothecae (Hemiptera: Aphididae)

European Journal of Entomology, 2010
The relative proportions of free amino acids as well as the amino acid compositions of hydrolysed unprecipitated peptides and hydrolysed whole carcasses were quantified for two aphid species: the gall-dwelling social aphid Pemphigus spyrothecae and the ...

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

Journal of Applied Entomology, EarlyView.
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...
