Abstract In northern central Chile, ephemeral pools constitute shallow isolated water bodies with a favourable habitat for fauna adapted to seasonal changes. Based on the limited knowledge about the fauna—particularly insects—associated to these ecosystems, the objective of this study was to ...

Percentage of importance indice-production unknown: loss and solution sources identification on system

Braz. j. biol; 84 (), 2024
Abstract Indices are used to help on decision-making. This study aims to develop and test an index, which can determine the loss (e.g., herbivorous insects) and solution (e.g., natural enemies) sources. They will be classified according to their importance regarding the ability to damage or to reduce the...

Introducción: Los Coleópteros acuáticos exhiben una gran importancia dentro de los cuerpos de agua, no solo por su papel en la cadena trófica, sino también por su papel como bioindicadores de la calidad del agua. A pesar de la gran importancia que representan, los estudios a nivel específico o sobr...

How omnivory affects the survival and choices of earwig Doru luteipes (Scudder) (Dermaptera: Forficulidae)?

Braz. j. biol; 83 (), 2023
Abstract Doru luteipes (Scudder, 1876) is an omnivorous predator that finds different food resources in the corn plant: eggs of Spodoptera frugiperda (J.E. Smith, 1797), uredospores of Puccinia polysora (Underw, 1897), and pollen. Knowing the survival and food preferences of this predator is essential to...
