Can monophagous specialists mediate host plant choices in generalist planthoppers (Hemiptera: Delphacidae)? [PDF]

open access: yesEcological Entomology, 2020
A preference experiment was set up with two planthopper species (Hemiptera: Delphacidae) to test the influence of competition on host plant choice. The delphacid ...

Spider Web DNA Metabarcoding Provides Improved Insight into the Prey Capture Ability of the Web-Building Spider Tetragnatha keyserlingi Simon (Araneae: Tetragnathidae)

open access: yesAgriculture
Spiders play a crucial role as predators in terrestrial ecosystems, particularly in controlling insect populations. Tetragnatha keyserlingi Simon (Araneae: Tetragnathidae) is a dominant species in rice field ecosystems, where it builds webs amidst rice ...

The planthopper genus Spartidelphax, a new segregate of Nearctic Delphacodes (Hemiptera, Delphacidae)

open access: yesZooKeys, 2014
The new genus Spartidelphax is described to house three species removed from the polyphyletic genus Delphacodes. The members of Spartidelphax are coastal species native to eastern North America, and probably feed exclusively on cordgrass (Poaceae, Spartina Schreb.). The taxonomy and nomenclature of the included species (viz.

Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

open access: yesInsect Conservation and Diversity, EarlyView.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling
