Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

Entomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Barley yellow dwarf epidemiology [PDF]

, 2006
Barley yellow dwarf (BYD) disease is induced by viruses that are vectored by aphids. The viruses infect grasses and cause severe damage on oats, barley and wheat worldwide.

Morph identification in natural populations of alate female bird cherry aphids, Rhopalosiphum padi L., by multivariate methods

, 1994
A discriminant analysis was done to determine which morphological characteristics contributed most to the identification of alate female morphs of Rhopalosiphum padi in natural populations collected from either Prunus padus or in suction traps.

Landscape and farm management influence generalist predators [PDF]

, 2002
Chemical pest control is currently the dominant form of pest management against insect pests in agroecosystems, but has negative side effects. Biological control by specialist predators has been successful in greenhouses, but has not been successfully ...

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.

Interactions between host-plant volatiles and the sex pheromones of the bird cherry-oat aphid, Rhopalosiphum padi and the damson-hop aphid, Phorodon humuli

, 2006
The bird cherry-oat aphid, Rhopalosiphum padi (L.), and the damson-hop aphid, Phorodon humuli (Schrank), migrate at the same time of year and colonize closely related Prunus spp.

Resistance of wheat cultivars to bird cherry-oat aphid, Rhopalosiphum padi (Hem.: Aphididae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2011
The bird cherry-oat aphid, Rhopalosiphum padi (L.), is polyphagous with a nearly worldwide distribution and known as an important pest of wheat and the main vector of barley yellow dwarf virus.

Regional Susceptibilities ofRhopalosiphum padi(Hemiptera: Aphididae) to Ten Insecticides [PDF]

Florida Entomologist, 2016
Abstract Rhopalosiphum padi (L.) (Hemiptera: Aphididae) is one of the most significant cereal pests worldwide. Control of R. padi has relied heavily on chemical insecticides. We sampled 12 populations of R. padi from 11 provinces in China and analyzed their regional susceptibilities to 10 insecticides by using the leaf dip method. The R.

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.
