Seasonal Occurrence of Life Stages of Grasshoppers (Orthoptera: Acridoidea) in the Southern Pampas, Argentina
TLDR
The seasonal occurrence of life stages of grasshopper species of the Southern Pampas was studied through sampling of representative habitats for 5 seasons, with only 1 species (Sinipta dalmani) spent the winter as a nymph.
Survival and fecundity of Dichroplus maculipennis and Ronderosia bergi (Orthoptera: Acrididae: Melanoplinae) following infection by Beauveria bassiana (Ascomycota: Hypocreales) under laboratory
TLDR
It was observed that infection with 1×103 conidia/ml altered nymphal development time, fecundity and adult survival in both species and among survivors of both the species, control adults lived longer than infected adults.
Beauveria bassiana (Ascomycota: Hypocreales) Introduced as an Endophyte in Corn Plants and Its Effects on Consumption, Reproductive Capacity, and Food Preference of Dichroplus maculipennis
TLDR
It was observed that B. bassiana as a corn plant endophyte negatively affected the daily consumption rate, fecundity and food preference of D. maculipennis.
Longevity and fecundity of Dichroplus maculipennis (Orthoptera, Acrididae) at non-outbreaking and outbreaking situations
TLDR
Since the daily oviposition rate at low and high densities was not significantly different, the diminished fecundity rate at high density is attributable to the reduced longevity of adult female D. maculipennis.
Status of the alien pathogen Paranosema locustae (Microsporidia) in grasshoppers (Orthoptera: Acridoidea) of the Argentine Pampas
TLDR
Susceptible species with geographic distributions mostly restricted to the establishment area and with numerically small populations, like the melanopline Scotussa daguerrei, are predicted to be the ones facing higher risks of negative impacts.
Naturalized, newly-associated microsporidium continues causing epizootics and expanding its host range
TLDR
This work presents a meta-anatomy of the Ecosistemas y Desarrollo Sustentable of La Plata, a 60-year-old monument dedicado to los exploradores de arquitectura y ciencias naturales de Buenos Aires.
Postembryonic development and food consumption of Dichroplus elongatus Giglio-Tos and Dichroplus maculipennis (Blanchard) (Orhtoptera: Acrididae: Melanoplinae) under laboratory conditions.
Dichroplus maculipennis (Blanchard) and D. elongatus Giglio-Tos are two of the most important melanoplines in Argentina, both ecologically and economically. The postembryonic development and forage
The Biology and some Population Parameters of the Grasshopper, Ronderosia bergi, Under Laboratory Conditions
Abstract Some biological and population parameters of Ronderosia bergi (Stål) (Orthoptera: Acrididae: Melanoplinae) were estimated by monitoring five cohorts of the first generation (F1) of
Neo-sex Chromosomes in the Maculipennis Species Group (Dichroplus: Acrididae, Melanoplinae): The Cases of D. maculipennis and D. vittigerum
TLDR
Analysis of karyotypic character state optimization strongly suggests the independent origin and evolution of neo-sex systems within the genus Dichroplus and its Maculipennis species group.
