Effects of different field managements on the abundance of cereal aphids (Sternorrhyncha: Aphidoidea).

open access: yesPlant Protection Science, 2004
The abundance of cereal aphids on winter wheat tillers and ears was determined in two field managements (integrated and ecological) at Dolná Malanta, Slovakia, over the years 1999-2001.

A note on current pyrethroid susceptibility in the bird cherry-oat aphid Rhopalosiphum padi in Ireland

open access: yesIrish Journal of Agricultural and Food Research, 2022
The objective of this study was to observe the response of the bird cherry oat aphid, Rhopalosiphum padi (Linnaeus, 1758) to field rate equivalents of insecticides, by using bioassays of vials coated with the pyrethroid, λ-cyhalothrin.

Genome of Russian wheat aphid an economically important cereal aphid

open access: yesStandards in Genomic Sciences, 2017
AbstractAlthough the hemipterans (Aphididae) are comprised of roughly 50,000 extant insect species, only four have sequenced genomes that are publically available, namely Acyrthosiphon pisum (pea aphid), Rhodnius prolixus (Kissing bug), Myzus persicae

The effect of within-crop habitat manipulations on the conservation biological control of aphids in field-grown lettuce [PDF]

open access: yes, 2011
Within-crop habitat manipulations have the potential to increase the biological control of pests in horticultural field crops. Wildflower strips have been shown to increase the abundance of natural enemies, but there is little evidence to date of an ...

Prevalent Pest Management Strategies for Grain Aphids: Opportunities and Challenges

open access: yesFrontiers in Plant Science, 2022
Cereal plants in natural ecological systems are often either sequentially or simultaneously attacked by different species of aphids, which significantly decreases the quality and quantity of harvested grain.

Genetic Resources of Cereal Crops for Aphid Resistance

open access: yesPlants, 2022
The genetic resources of cereal crops in terms of resistance to aphids are reviewed. Phytosanitary destabilization led to a significant increase in the harmfulness of this group of insects. The breeding of resistant plant genotypes is a radical, the cheapest, and environmentally safe way of pest control.

Effect of chlorophenoxy herbicides residues on probing behavior of cereal aphid

open access: yesAgronomy Science, 2018
Chlorophenoxyacetic herbicides such as 4-chloro-2-methylphenoxyacetic acid (MCPA) and 2,4-dichlorophenoxyacetic acid (2,4-D) are used for cereal protection.

DIMBOA levels in hexaploid Brazilian wheat are not associated with antibiosis against the cereal aphids Rhopalosiphum padi and Sitobion avenae [PDF]

open access: yes, 2017
The objective of this study was to evaluate the natural levels of the plant defence compound DIMBOA in young leaves of eight hexaploid Brazilian wheat genotypes and the impact of the genotypes upon development of cereal aphids, Rhopalosiphum padi and ...
