Temperatura y fotoperíodo: qué influencia ejercen en el desarollo ninfal de Cornops aquaticum (Orthoptera: Acrididae)?

open access: yes, 2007
Development of the semi-aquatic acridid Cornops aquaticum on Eichhornia crassipes (Pontederiaceae) was investigated in the laboratory. Influence of constant (12 and 27 °C) and variable (36/3 °C and 36/4.5 °C) temperatures as well as constant (24 h day) and variable (14 h day/ 10 h night) photoperiods were analysed. The highest survival of nymphs (69 %)

Cornops aquaticum (Orthoptera, Acrididae, Leptysminae): aceitação de plantas alimentares por ninfas vivendo em Eichhornia azurea (Pontederiaceae) no Pantanal Norte, Brasil

open access: yes, 2005
Nymphs of all developmental stages of Cornops aquaticum were collected from their host Eichhornia azurea in northern Pantanal wetlands, Mato Grosso, Brazil. Nine aquatic macrophytes and two vegetable species were offered as a food source three times during a 12 day period in the laboratory (different seasons).

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 ...
