Ant-aphid interactions in multispecies ant communities: Some ecological and ethological aspects

European Journal of Entomology, 2005
Investigations of the interactions between aphids and ants in multispecies ant communities and an experimental investigation of some ethological aspects of ant-aphid interactions were carried out in mixed forests at Novosibirsk Academic Centre, from 1998-

Aphid Pheromones

, 2010
Aphids are the main insect pests of agricultural crops in temperate regions causing major economic losses. Although broad-spectrum insecticides are available for control, alternative and more targeted methods are needed due to insecticide resistance and increasing environmental pressures.

Effect of epicuticular waxes from triticale on the feeding behaviour and mortality of the grain aphid, Sitobion avenae (Fabricius) (Hemiptera: Aphididae)

Journal of Plant Protection Research, 2016
Surface waxes from wax-covered triticale plants (RAH 122) were sprayed on plants of the waxless genotype RAH 366 or the surface waxes were used to make artificial diet preparations.

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.

Host plants and obligate endosymbionts are not the sources for biosynthesis of the aphid alarm pheromone

Scientific Reports, 2017
(E)-β-farnesene (EβF) is the major component of the alarm pheromone of many aphid species, but where EβF is synthesized in aphids is only partly understood.

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.

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 ...

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.
