The Effects of Different Diets and Transgenerational Stress on Acyrthosiphon pisum Development. [PDF]

open access: yes, 2019
Despite the fact that sap-feeding hemipterans are major agricultural pests, little is known about the pea aphid's (Acyrthosiphon pisum) nymphal development, compared to other insect models. Given our limited understanding of A.

Does a shift to a novel host plant create a defence‐free space for a specialist herbivore species?

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While host switches can promote speciation in herbivorous insects, the benefits of switching hosts have only been ascribed to escaping competition and natural enemies. Herbivores might also escape from the defences of their ancestral host if their new host species lacks

Praon volucre (Hymenoptera: Braconidae: Aphidiinae), a natural enemy of Macrosiphum euphorbiae (Hemiptera: Aphididae): Life table and intrinsic rate of population increase

open access: yesEuropean Journal of Entomology, 2011
Life table data of natural enemies are often used to understand their population dynamics and estimate their potential role in the biological control of pests.

An integrative strategy used by the aphid Uroleucon formosanum to counter host sesquiterpene lactone defense: Insights from combined genomic and transcriptomic analysis

open access: yesInsect Science, EarlyView.
We report the first high‐quality chromosome‐level genome assembly for the aphid Uroleucon formosanum, a serious pest that infests lettuce in eastern Asia. A combination of comparative genomic analyses and RNA‐seq transcriptome profiling suggests that U. formosanum employs integrative mechanisms to cope with host plant‐derived sesquiterpene lactone (STL)

Relation between plant water status and Macrosiphum euphorbiae (Hemiptera: Aphididae) population dynamics on three cultivars of tomato

open access: yesEuropean Journal of Entomology, 2013
Deficit irrigation scheduling is used to increase the efficiency with which water is used in many crops including tomato, however a water deficit is predicted to favour phloem feeding insects.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Economic Threshold for Soybean Aphid (Hemiptera: Aphididae) [PDF]

open access: yesJournal of Economic Entomology, 2007
Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), reached damaging levels in 2003 and 2005 in soybean, Glycine max (L.) Merrill, in most northern U.S. states and Canadian provinces, and it has become one of the most important pests of soybean throughout the North Central region.

The degree of protection different ants (Hymenoptera: Formicidae) provide aphids (Hemiptera: Aphididae) against aphidophages

open access: yesEuropean Journal of Entomology, 2012
Aphids play an important role in the life of many ant species supplying them with energy-rich carbohydrate food and in exchange receiving some degree of protection from natural enemies.
