Article Synopsis
  • - In February 2022, 16 Canary Island date palms in Mexico City displayed symptoms of pink rot disease, with a 27% incidence and 12% severity, showing necrotic lesions that progressed from the petiole to the rachis.
  • - Mycelia from infected tissues were cultured on potato dextrose agar, resulting in 20 fungal colonies that resembled the characteristics of a known pathogen, identified as (Biourge) Schroers.
  • - Genomic DNA was extracted from one fungal isolate, sequenced for the internal transcribed spacer (ITS) and large subunit (LSU) regions, and placed in a specific phylogenetic clade, confirming its pathogenicity through tests on date

Inquiline oak gall wasps from the genus Synergus Hartig (Hymenoptera: Cynipidae: Synergini) that occur in the New World should be classified into the following morphological groups: i) species with the radial cell of fore wings open; ii) species with the radial cell of fore wings closed and mesopleurae completely sculptured, always with transversal striae covering its surface; iii) species with the radial cell of fore wings closed and mesopleurae partially smooth, with the speculum always shiny and not sculptured. The latter group, which appears to be unique to the New World's fauna, is the focus of this study. An exhaustive taxonomical revision of all the Synergus species within this morphological group is carried out for the first time after the initial treatment by Lobato-Vila Pujade-Villar (2017).

Various studies have demonstrated that the foundation species genetic diversity can have direct effects that extend beyond the individual or population level, affecting the dependent communities. Additionally, these effects may be indirectly extended to higher trophic levels throughout the entire community. is an oak species with characteristics of foundation species beyond presenting a wide geographical distribution and being a dominant element of Mexican temperate forests.
