Expression pattern analysis of odorant-binding proteins in the pea aphid Acyrthosiphon pisum [PDF]

, 2015
Odorant-binding proteins (OBPs) are soluble proteins mediating chemoreception in insects. In previous research, we investigated the molecular mechanisms adopted by aphids to detect the alarm pheromone (E)-\u3b2-farnesene and we found that the recognition

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

Insect Molecular Biology, EarlyView.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Loss‐of‐Function Mutation in CER2‐LIKE1 Reduced Accumulation of Cuticular Wax and Susceptibility to Thrips in Welsh Onion

Plant Biotechnology Journal, EarlyView.
ABSTRACT Cuticular waxes can form a hydrophobic barrier on aerial plant surfaces, which is essential for mediating plant‐environment interactions by providing protection against both biotic and abiotic stresses. In this study, a cuticular wax mutant (gl) was identified and characterised in Welsh onion (Allium fistulosum L.), exhibiting a functional ...

Rhizobia–Bean Symbiosis Increases Root Herbivore Attraction and Growth via Volatile Signals and Enhanced Nutrition

Plant, Cell &Environment, EarlyView.
ABSTRACT The symbiosis between nitrogen‐fixing rhizobia and plants is considered mutually beneficial, yet its indirect effects on other organisms remain understudied. We examined how rhizobia symbiosis in Phaseolus vulgaris influences the behaviour and performance of Diabrotica balteata larvae. Specifically, we tested larval preference for nodulated (R+

Identification of ion channel genes in the Acyrthosiphon pisum genome [PDF]

Insect Molecular Biology, 2010
Abstract Aphids are major pests of crops, causing hundreds of millions of dollars worth of damage annually. Ion channel proteins are often the targets of modern insecticides and mutations in ion channel genes can lead to resistance to many leading classes of insecticides. The sequencing of the pea aphid,

The effects of a synthetic insecticide and a mineral oil on alfalfa insect pests [PDF]

Pesticidi i Fitomedicina, 2018
The effects of the synthetic insecticide Eforia 043 ZK (thiamethoxam+lambdacyhalothrin), applied alone and at 1/5 and 2/5 reduced doses in a mix with the mineral oil Akarzin, on Tychius flavus Beck.

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

Plant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Isozymes of a population of Acyrthosiphon pisum (Aphididae)

, 1983
L’étude d’une population d’Acyrthosiphon pisum, clonée à partir d’oeufs d’hiver et de femelles anholocycliques, a montré une variabilité isoenzymatique réduite. Seule une des estérases se caractérisant par un triplet de bandes a présenté une certaine variabilité allélique. Deux autres loci estérasiques, se situant de part et d’autre sur le gel, étaient

Aphid honeydew: An arrestant and a contact kairomone for Episyrphus balteatus (Diptera: Syrphidae) larvae and adults

European Journal of Entomology, 2014
Predator searching efficiency increases in response to a variety of environmental cues associated with its prey. The sugary excretion of aphids (honeydew) has been found to act as a prey-associated cue for many aphid natural enemies. In the present study,
