A landscape view of cereal aphid parasitoid dynamics reveals sensitivity to farm- and region-scale vegetation structure

open access: yesEuropean Journal of Entomology, 2008
Functioning of plant-aphid-natural enemy interactions may be associated with the structure and composition of withinfield vegetation, neighborhood fields and field borders, and the regional plant community of cropped and noncropped areas.

Partial consumption of different species of aphid prey by the predator Macrolophus pygmaeus (Hemiptera: Miridae)

open access: yesEuropean Journal of Entomology, 2016
The partial consumption of prey refers to when a predator does not consume all the digestible biomass of an animal it has killed. The frequency of partial consumption of prey by the polyphagous predator Macrolophus pygmaeus (Hemiptera: Miridae) was ...

The largest aphid mitochondrial genome found in invasive species Therioaphis tenera (Aizenberg, 1956)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The complete mitochondrial genome of Therioaphis tenera (Aizenberg) was sequenced using Ion Torrent sequencing technology. The genome is 19,200 bp in length, which is the largest mitochondrial genome of aphids that has been sequenced so far.

DIVERSITY OF APHIDIDAE OF UTTARAKHAND

open access: yes, 2023
Agricultural crops face numerous pest-problems, particularly due to aphids, scale-insects, mealybugs, white-flies, mites, etc. Aphids (Homoptera: Aphididae) are one of the important pests of crops, and are highly injurious for cultivated and non-cultivated crops. We reported eighteen aphid species belong to twelve genera in Kumaun region.

Flight activity of aphids in Serbia: investigation by water traps placed in sugar beet fields

open access: yesPlant Protection Science, 2023
Plant viruses, and aphids as their vectors, are limiting factors in sugar beet production. Viral plant diseases are currently impossible to treat but knowing the flight patterns of aphids can help in reducing the number of potential virus vectors ...

Effect of ant attendance on aphid population growth and above ground biomass of the aphid's host plant

open access: yesEuropean Journal of Entomology, 2017
Ant-aphid mutualism is considered to be a beneficial association for the individuals concerned. The population and fitness of aphids affected by ant attendance and the outcome of this relationship affects the host plant of the aphid.
