The nutritional value of aphid honeydew for non-aphid parasitoids [PDF]

Basic and Applied Ecology, 2008
Intake of sugar-rich foods by adult parasitoids is crucial for their reproductive success. Hence, the availability of suitable foods should enhance the efficacy of parasitoids as biological control agents. In situations where nectar is not readily available, homopteran honeydew can be a key alternative food source.

Companion Plants for Aphid Pest Management

Insects, 2017
A potential strategy for controlling pests is through the use of “companion plants” within a crop system. This strategy has been used in several trials to fight against a major crop insect pest: the aphid.

Interaction between the Bird Cherry-Oat Aphid (Rhopalosiphum padi) and Stagonospora Nodorum Blotch (Parastagonospora nodorum) on Wheat

Insects, 2021
Wheat plants are under constant attack by multiple pests and diseases. Until now, there are no studies on the interaction between the aphid Rhopalosiphum padi and the plant pathogenic fungus Parastagonospora nodorum causal agent of septoria nodorum ...

The Mitochondrial Protein RESISTANCE to APHIDS 9 Interacts with S40 to Resist Aphid Infestation by Modulating Reactive Oxygen Species Homeostasis in Maize (Zea mays)

Advanced Science, EarlyView.
This study identifies the mitochondrial protein RTA9, a member of the Domain of Unknown Function 641 family, together with its partner S40, as key regulators of aphid resistance in maize. RTA9 promotes S40 degradation and modulates reactive oxygen species accumulation.

Ants and Aphides [PDF]

Nature, 1872
AMONG other misstatements in Dr. Bree's “Fallacies of Darwinism,” so ably criticised by Mr. Wallace in NATURE of July 25, occurs the following:—“All the stories about aphides being treated as milch-cows are myths, the result of inaccurate observation” (p. 166).

Viral Systemic Movement Is Enhanced by Alteration of a Structural Phloem Protein by the Insect Vector

Advanced Science, EarlyView.
Aphids release salivary protein GLD into plants, which induces ROS in the phloem. This leads to the intermolecular disulfide bonds formation among SEO proteins, promoting their transition from the dispersed state to the aggregated state. SEO can interact with CMV CP.

Enhancing protein signal detection in asexual and viviparous pea aphids: A guided protocol for tissue dissection and proteinase K treatment

MethodsX
Aphids, as hemipteran insects, reproduce via parthenogenesis and viviparity, resulting in rapid and exponential offspring production. To investigate the molecular mechanisms underlying parthenogenetic viviparity in asexual aphids, precise protein ...

Electrostatic Insect Repulsion, Capture, and Arc-Discharge Techniques for Physical Pest Management in Greenhouses

Agronomy, 2022
This article reviews the development of electrostatic apparatuses for controlling insect pests in greenhouses. The apparatuses control insects by repelling them, capturing them, and killing them by producing an arc discharge.

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

Advanced Science, EarlyView.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide
