The poplar bark beetle (Coleoptera: Scolytidae) is a key pest of poplar trees (Malpighiales: Salicaceae, genus ) across northern Spain. However, among the more than 200 poplar clones available on the market, the clone USA 184-411 has the highest susceptibility to attacks. We tested the hypothesis that compounds released by the most susceptible poplar clone chemically mediate behavior.

- Trichothecenes are toxins from certain fungi that impact plant disease and biological control, and are characterized by a common structure called EPT, with variations in a macrocyclic ring formation.
- Recent research identified the TRI24 gene as essential for forming this macrocyclic ring in the fungus Paramyrothecium roridum.
- A mutant strain lacking TRI24 displayed reduced severity in plant disease and antifungal activity, highlighting the significance of the macrocyclic ring in the biological functions of these trichothecenes.
Article Synopsis
- Olivier 1795 is a beetle pest that damages grapevines in Spain by boring into the wood, leading to both direct harm and an increased risk of wood fungi infections.
- Research aimed to measure the extent of wood damage caused by the larvae and determine the wood's resistance using compression and flexural tests.
- Findings indicated that trunks have a higher effective section and stability compared to branches, suggesting that branches are more vulnerable to breaking when infested by the larvae; further studies are recommended across different grapevine varieties and attack periods.
strains used in vineyards for the control of grapevine trunk diseases (GTDs) present a promising alternative to chemical products. Therefore, the isolation and characterization of new indigenous strains for these purposes is a valuable strategy to favor the adaptation of these strains to the environment, thus improving their efficacy in the field. In this research, a new species, , isolated from vineyards in Ribera de Duero (Spain) area, has been identified and phylogenetically analyzed using 20 housekeeping genes isolated from the genome of 24 species.

The places studied belonged to the regions of Entre-Douro-e-Minho, Beira Interior, and Trás-os-Montes. To achieve the proposed objectives, buds were collected for egg and larva observation, galls were collected for larva, pupa, and adult observation and monitoring, and emergency boxes were used to identify the fauna present in the galls.
