Gonipterus platensis es un insecto plaga introducido que afecta a las plantaciones de Eucaliptus y constituye un importante problema, dado que las larvas y adultos se alimentan de las hojas. El uso de hongos entomopatógenos capaces de colonizar y matar a estos insectos constituye una alternativa a la aplicación de insecticidas para su manejo.

Diverse practices related to livestock intensification often have a deep impact on grassland diversity. Moreover, alternative degraded states that are hardly reversible can be observed, resulting in low-diversity communities, dominated by invasive alien species. Therefore, the need arises to understand aboveground vegetation dynamics in these communities, and the potential of the seed bank to revert this degradation.

ABSTRACT.- The major surface protein 1a (MSP1a) gene has been used to characterize Anaplasma marginale genetic diversity. This pathogen causes significant productivity and economic losses to the cattle industry. The objective of the present study was to report the first characterization of A. marginale genetic diversity in Uruguay based on MSP1a genotypes and their putative relationship with Rhipicephalus microplus. This cross-sectional study was conducted between 2016 and 2020.
