Distribution and use of grasslands in the Czech Republic and biodiversity of invertebrates [PDF]

open access: yes, 2008
In the Czech Republic the major focus of organic farming lies in permanent grasslands management. Animal production is mostly focused on non-milk pasture beef-raising on almost the whole farm area. By contrast conventional farms do not grass sufficiently,

First Record of Fusarium verticillioides as an Entomopathogenic Fungus of Grasshoppers

open access: yesJournal of Insect Science, 2011
Fusarium verticillioides (Saccardo) Nirenberg (Ascomycota: Hypocreales) is the most common fungus reported on infected corn kernels and vegetative tissues, but has not yet been documented as being entomopathogenic for grasshoppers.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Grasshoppers confirm mild winter [PDF]

open access: yes, 2002
If we use grasshoppers as a gauge of winter severity then the winter of 2001-2002 was certainly an insect-friendly winter. I noted in the December 2001 Integrated Crop Management newsletter that a few differential grasshoppers had survived around Ames ...

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

open access: yesInsect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Diversidad y distribución de acridios (Orthoptera: Acridoidea) en pastizales del sur de la región pampeana, Argentina Diversity and distribution of grasshoppers (Orthoptera: Acridoidea) in grasslands of the Southern Pampas region, Argentina

open access: yesRevista de Biología Tropical, 2013
Los acridios son componentes nativos de los pastizales, dichos sistemas han sido modificados debido a la intensificación de las actividades agrícola-ganaderas y por lo tanto se considera importante estudiar las comunidades de acridios asociadas.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...
