Generalist predators disrupt parasitoid aphid control by direct and coincidental intraguild predation [PDF]

, 2011
Generalist predators and parasitoids are considered to be important regulators of aphids. The former not only feed on these pests, but might also consume parasitoids at all stages of development.

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

Plant 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.

The age of tomato plants affects the development of Macrosiphum euphorbiae (Thomas, 1878) (Hemiptera) colonies

Agronomía Colombiana, 2021
We tested the hypothesis that the intensity and duration of Macrosiphum euphorbiae infestations in tomato depend on both the age (phenological stage) of the host plant and the initial number of aphids present in the colony.

Temporal variations in the life-cycles of aphids (Sternorrhyncha: Aphididae) and their coccinellid predators

European Journal of Entomology, 2015
Aphids are either monoecious living either on trees or herbaceous plants, or heteroecious, which involves host alternating between a tree (primary host) and a herbaceous plant (secondary host).

Diversity of aphids (Hemiptera: Aphididae) associated with potato crop in Tizi-Ouzou (North of Algeria), with new records

Acta Agriculturae Slovenica, 2021
Aphids are among the phytophagous pests that cause serious damage to crop plants. In Northern Algeria, we have little information on their diversity. In this context, the study of the diversity of aphids was carried out in three regions of Tizi-Ouzou ...

Aphid transmission of nanoviruses [PDF]

Archives of Insect Biochemistry and Physiology, 2020
AbstractThe genus Nanovirus consists of plant viruses that predominantly infect legumes leading to devastating crop losses. Nanoviruses are transmitted by various aphid species. The transmission occurs in a circulative nonpropagative manner. It was long suspected that a virus‐encoded helper factor would be needed for successful transmission by aphids ...

How Cabbage Aphids Brevicoryne brassicae (L.) Make a Choice to Feed on Brassica napus Cultivars

Insects, 2019
Plant resistance to aphids might be present in different plant tissues, such as the epidermis, mesophyll and phloem, but not all of them play a key role in determining the feeding preference of aphids.

Large-scale gene discovery in the pea aphid Acyrthosiphon pisum (Hemiptera) [PDF]

, 2006
Aphids are the leading pests in agricultural crops. A large-scale sequencing of 40,904 ESTs from the pea aphid Acyrthosiphon pisum was carried out to define a catalog of 12,082 unique transcripts.
