Stage specific consumption and utilization of aphids, conspecific and heterospecific eggs by two species of Coccinella (Coleoptera: Coccinellidae)

European Journal of Entomology, 2014
The nutritive quality of aphids, conspecific and heterospecific eggs as food for ladybirds is a controversial issue. If ladybirds find aphids more palatable than eggs then they are more likely to efficiently exploit and be biocontrol agents of aphids. If

Metabolite‐based resistance in wheat varieties to aphid virus vectors: progress and future opportunities

Pest Management Science, Volume 81, Issue 11, Page 7276-7287, November 2025.
Sitobion avenae and Rhopalosiphum padi are major pests on wheat. Natural product‐based aphid resistance holds promise for the sustainable control of these pests. The current literature is discussed, highlighting knowledge gaps and challenges that need addressing. Abstract Cereal aphids, Sitobion avenae and Rhopalosiphum padi, cause severe yield loss in

Fates of Rare Species under Siege from Invasion: Persistence of Coccinella novemnotata Herbst in Western North America alongside an Invasive Congener

Frontiers in Ecology and Evolution, 2017
Species invading new geographic regions may threaten continued existence of similar, indigenous relatives, particularly those species whose rarity may reflect an already tenuous existence.

The transfer and fate of Pb from sewage sludge amended soil in a multi-trophic food chain: a comparison with the labile elements Cd and Zn [PDF]

, 2015
The contamination of agroecosystems due to the presence of trace elements in commonly used agricultural materials is a serious issue. The most contaminated material is usually sewage sludge, and the sustainable use of this material within agriculture is ...

Indirect plant defense may provide economically important pest suppression in sorghum

Pest Management Science, Volume 81, Issue 11, Page 7478-7488, November 2025.
Laboratory measures of sorghum direct and indirect plant resistance traits aligned with natural enemy recruitment and pest suppression in the field. Abstract BACKGROUND A promising strategy to optimize biological control of insect pests is selecting crop varieties with indirect defense traits.

Aphid Species Affect Foraging Behavior of Coccinella septempunctata (Coccinellidae: Coleoptera)

Pakistan Journal of Biological Sciences, 2017
Flowers are admirable in scenic good looks and artistic beautification. These are also playing necessary roles in therapeutic preparations. Aphid is an important sucking pest of various flowers in ornamental territories and it is generally controlled by predators, so it was necessary to evaluate which aphid species affect the predator more or less ...

Why is Coccinella septempunctata so successful? (A point-of-view) [PDF]

European Journal of Entomology, 2008
Factors were examined that could be responsible for the predominance of Coccinella septempunctata (C7) in most habitats of the Palaearctic and for its successful invasion of the Nearctic Region. C7 is euryphagous, but less polyphagous than Harmonia axyridis or Coleomegilla maculata in that it cannot develop or reproduce on non-aphid food.

Identification of potential predators of western bean cutworm (Striacosta albicosta) in field corn through molecular gut‐content analysis

Entomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1165-1176, November 2025.
The noctuid pest western bean cutworm (Striacosta albicosta) lays its eggs in corn fields over the season. Various generalist predators consume the eggs and larvae of this pest. To improve integrated pest management of S. albicosta, this study identified key trophic interactions between S. albicosta and predatory arthropods in corn fields.
