Ongoing shifts in climate and land use have altered interactions between trees and insect herbivores, changing biotic disturbance regimes. However, as these changes are complex and vary across host species, insect taxa, and feeding guilds, they remain poorly understood. We compiled annual records of forest insect disturbance from 15 countries in temperate and boreal Europe, spanning the period from 2000 to 2022. The dataset comprises 1361 time series characterizing the dynamics of 50 herbivorous insects. We used this dataset to test whether insect disturbance has systematically changed during the 23‐year period across host trees and feeding guilds, whether it varies along latitudinal and climatic gradients, and whether synchrony exists among species in the same guild or among species sharing the same host. Since 2000, borer disturbance was predominantly concentrated on gymnosperms, while defoliators impacted gymnosperms and angiosperms more evenly. While 85.8% of gymnosperm disturbance was inflicted by a single species, Ips typographus , the majority of disturbances to angiosperms were caused by six different species. Borer impact on gymnosperms has increased in the 21st century, while defoliator impact has decreased across both clades. In contrast to diverging temporal trends, disturbance was consistently greater in warmer and drier conditions across feeding guilds and host types. We identified significant synchrony in insect disturbance within host types and feeding guilds but not between these groups, suggesting shared drivers within guilds and host types. Increasing insect disturbance to gymnosperms may catalyze adaptive transformations in Europe's forests, promoting a shift from historical conifer‐dominated management to broadleaved trees, which are less affected by insect herbivores. Our findings reveal a diversity of trends in insect herbivory, underscoring the need to strengthen monitoring and research in order to better understand underlying mechanisms and identify emerging threats that may not be apparent in currently available data.

Insect farming is gaining increasing attention because of the ability of insects to upscale a variety of waste and by-product biomass efficiently into proteins and lipids. In the European Union and in Norway, the use of insects is permitted in formulated pig, poultry, and fish feeds and more recently for human consumption. However, the European Food Safety Authority has highlighted the lack of data regarding the safety of processing pesticide-contaminated biomass by insects into feed or food products. Secondly, the presence of insecticide residues in plant biomass might negatively affect the growth or survival of the insects themselves. This study aimed to evaluate the fate of the insecticide pirimiphos-methyl (PM) in black soldier fly (Hermetia illucens, BSF) and yellow mealworm (Tenebrio molitor, YMW) larvae composting. PM is a dominant pesticide found in relevant insect biomasses. Newly hatched larvae were fed on a standard poultry feed substrate spiked with pirimiphos-methyl at different concentrations: 10, 20, and 40 mg/kg (wet base), under optimal breeding conditions. Poultry feed substrate spiked with methanol served as control group. When the feeding media were spiked with 20 and 40 mg/kg of PM, the survival of both BSF and YMW larvae decreased. Mean larvae mass for both species was reduced with increasing concentrations of PM. PM and 7 compounds were identified in a metabolites/transformation product screen that was aided by in silico predictions. One compound, dihydroxy-PM was uniquely detected in larvae. Neither insect species appears to accumulate PM metabolites, and 90% of PM was metabolised. Results indicate that these insects can be reared on PM-contaminated biomass without risk of PM accumulation.
