Background: Biological control in integrated pest management (IPM) often overlooked avian predators until the emergence of the ecosystem services approach. Birds are now recognized as key regulators of pest populations in agroforestry landscapes due to their high mobility. The invasive yellow-legged hornet, introduced into Europe in 2004, threatens agriculture, beekeeping and native pollinators.

One undescribed fatty glyceride (), two unreported -acetyldopamine dimers ( and ), and four known structurally diverse -acetyldopamine dimers were isolated from adult Smith. Their structures were elucidated based on a comprehensive analysis of spectroscopic data, HRESIMS, and NMR calculations with ML_J_DP4, and the absolute configurations of and were determined via ECD calculations. Regarding their bioactivities, compounds and can inhibit the production of NO.

- An eco-monitoring program in northern Spain discovered the southern giant hornet, marking its first appearance in Europe, while assessing insect biodiversity related to yellow-legged hornet trapping.
- The study characterizes this new hornet using both morphological traits and genetic analysis, helping to distinguish it from other local hornet species.
- Concerns are raised about the southern giant hornet's potential threats to human health and ecosystems due to its predatory nature, underscoring the importance of insect trapping for early detection of invasive species.

The Asian hornet, , is an invasive species that has not only expanded its range in Asia but has also invaded European countries, and it incurs significant costs on local apiculture. This phylogeographic study aims to trace the evolutionary trajectory of and its close relatives; it aims to identify features that characterize an invasive species. The last successful invasion of into France occurred in late May, 2002, and into South Korea in early October, 2002, which were estimated by fitting a logistic equation to the number of observations over time.

(Lepeletier, 1836) (Hymenoptera: Vespidae) is a eusocial insect that lives in colonies of hundreds to thousands of individuals, which are divided into castes according to their task: queens, workers, and males. The proper functioning of the colony requires communication between the individuals that make up the colony. Chemical signals (pheromones) are the most common means of communication used by these insects to alarm and differentiate between individuals belonging or not to the colony.
