A RANGELAND GRASSHOPPER INSURANCE PROGRAM [PDF]
The incidence of benefits and costs from controlling rangeland grasshoppers on public grazing lands poses problems of economic efficiency and distributional equity. Public grasshopper control programs operate like public disaster assistance.

Iflaviruses in arthropods: when small is mighty
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.

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

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 ...

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

ABSTRACT We situate this article from/with/in the Necrocene, a geological period marked by the systematic production of human and more‐than‐human death to an extent that ecological destruction, extinction, loss and harm have become a structural feature of modern life.

The locust Oedaleus decorus undergoes massive outbreaks and engages in round-trip migratory flights across northern China and Mongolia. However, its specific genetic structure remains poorly understood.
