Against the central-marginal model: Three cases in chromosomally polymorphic grasshoppers (Orthoptera: Acrididae)

open access: yesEuropean Journal of Entomology, 2012
The central-marginal model is widely accepted in chromosomally polymorphic species of Drosophila. In fact, geographically and ecologically central populations of Drosophila show higher levels of polymorphism for paracentric inversions, whereas marginal ...

[Biomass of Cornops aquaticum (Orthoptera: Acrididae) in wetlands of Northeast Argentina].

open access: yesRevista de biologia tropical, 2015
The estimation of biomass in insect populations is a key factor to quantify the available resources and energy fluxes in ecosystems food webs. Cornops aquaticum is a common herbivore in Eichhornia plants in wetlands of Northeast Argentina. We aimed to analyse its biomass variation, related to the different grasshopper age categories populations in two ...

Diet preference of the different life stages of the aquatic grasshopper Cornops aquaticum (Orthoptera: Acrididae) and its implications for the biológica! control of water hyacinth [PDF]

open access: yes, 2022
Host specificity determination of weed biological control agents has historically relied on evidence generated through quarantine trials in the region of introduction. These trials are conservative and where possible, more research should be conducted in
