Density dependence of the alarm pheromone effect in pea aphids, Acyrthosiphon pisum (Sternorrhyncha: Aphididae)

open access: yesEuropean Journal of Entomology, 2007
The aphid alarm pheromone is known to trigger wing induction in pea aphids (Acyrthosiphon pisum). In reaction to alarm pheromone, aphids drop off the plant or walk away.

Effects of Phytoplasma Infection on Aster Leafhopper (Macrosteles quadrilineatus) Settling Behavior and Development on Brassica napus

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.

Prey preference and biomass consumption of Macrolophus pygmaeus (Hemiptera: Miridae) fed Myzus persicae and Macrosiphum euphorbiae (Hemiptera: Aphididae)

open access: yesEuropean Journal of Entomology, 2007
The predation rate of the polyphagous predator Macrolophus pygmaeus (Rambur) when offered two aphid species, Myzus persicae (Sulzer) and Macrosiphum euphorbiae (Thomas), was investigated.

Abundance of Rice Root Aphid Among Selected Plant Species and on Plants Grown With Different Soil-Surface Media [PDF]

open access: yes, 2018
The rice root aphid, Rhopalosiphum rufiabdominalis (Sasaki), is distributed worldwide and colonizes a wide range of plants. However, relatively little is known about the suitability of different host plants, optimal rearing techniques, and the aphid’s ...

Competitive Interactions Between Generalist Predators and Their Effects on Shared and Non‐Shared Pests in a Greenhouse Crop

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Orius laevigatus engages in unidirectional intraguild predation on Transeius montdorensis. Despite this, both predators coexisted and suppressed the shared thrips prey. Aphids, a non‐shared prey, were effectively controlled by O. laevigatus even when its population was limited due to intraguild predation. T.

Morphological Differentiation Between \u3ci\u3eAphis Spiraecola\u3c/i\u3e and \u3ci\u3eAphis Pomi\u3c/i\u3e (Homoptera: Aphididae) [PDF]

open access: yes, 2017
Aphis pomi and Aphis spiraecola, are both found on agriculturally important hosts such as apple and pear, and in trap collections. Their morphological similarity makes identification difficult.

Using citizen science as a research prioritization tool to detect co‐occurrences of the invasive species Harmonia axyridis

open access: yesInsect Conservation and Diversity, EarlyView.
We studied co‐occurrences and potential novel interactions between the invasive ladybird Harmonia axyridis and local biota (plants, arthropods and fungi) across Argentina using citizen science records. We detected co‐occurrences (mainly Asteracea and Aphididae) and previously unreported interactions (predation, parasitism, interspecific mating and ...

Evaluation of the susceptibility of the pea aphid, Acyrthosiphon pisum, to a selection of novel biorational insecticides using an artificial diet [PDF]

open access: yes, 2009
An improved technique was developed to assay the toxicity of insecticides against aphids using an artificial diet. The susceptibility of the pea aphid Acyrthosiphon pisum (Harris) (Hemiptera: Aphidoidea) was determined for a selection of novel ...
