Acoustic Signals of \u3ci\u3eGraminella Nigrifrons\u3c/i\u3e (Homoptera: Cicadellidae) [PDF]

open access: yes, 2017
The deltocephaline leafhopper, Graminella nigrifrons, produces low intensity sub- strate transmitted vibrations (signals) to facilitate location of virgin females by males during courtship.

Using fecal DNA metabarcoding to investigate the animal diet of black rails, yellow rails, and soras

open access: yesWildlife Society Bulletin, EarlyView.
We used fecal DNA metabarcoding to investigate the diet of yellow rails, Eastern black rails, and sora during the non‐breeding season. Arthropods, particularly ants, were prevalent in their diets, suggesting possible interactions with invasive red imported fire ants.

Generalist predators function as pest specialists: Examining diet composition of spiders and ladybeetles across rice crop stages

open access: yesJournal of Applied Ecology, EarlyView.
By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

open access: yesInsect Molecular Biology, EarlyView.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Delphacidae of Alaska (Homoptera: Fulgoroidea)

open access: yesGreat Basin naturalist memoirs., 1988
Fifteen species, in 10 genera, of Delphacidae are recorded from Alaska. One, Kusnezoviella macleani , is described as new to science. Acanthodelphax analis (Crawford), Javesella arcanastyla (Beamer), and J. atrata (Osborn) are new combinations. Delphacodes saileri Beamer is a synonym of Javesella simillima (Linnavuori).
