Article Synopsis
- Biological invasions, particularly by the Yellow-legged hornet, pose significant ecological and economic threats, especially to honey bees and beekeeping practices.
- The study used field data and modeling to assess the mortality risk to bee colonies and estimated that up to 29.2% of colonies could face mortality annually due to these hornets, leading to potential economic losses of €30.8 million per year for beekeepers.
- Findings indicate that there's a pressing need for better financial assessments of the impacts of invasive species on biodiversity to inform conservation policies.
The woolly poplar aphid, Phloeomyzus passerinii (Signoret) (Hemiptera: Aphididae), is a major pest of poplar plantations in the Mediterranean basin and the Near East. Aphids colonize poplar trunks and feed upon the cortical parenchyma. Despite the economic importance of poplar, little is known about the mechanisms involved in poplar resistance to this pest.

Species able to exploit woody parts have either specific adaptations, such as extra long stylets that allow them to reach the phloem, or the ability to induce galls. The woolly poplar aphid, Phloeomyzus passerinii (Signoret) (Hemiptera: Aphididae), colonizes the trunks and base of the lower branches of mature poplars and causes cortical necrosis leading to the death of trees where infestation is heavy.
