In this study, we used pheromone traps and cone inventory to document the phenology and population trends of three important lepidopteran seed and cone consumers, viz. the spruce seed moth, <i>Cydia strobilella,</i> the spruce coneworm, <i>Dioryctria abietella</i> and the cloaked pug, <i>Eupithecia abietaria</i>, in six south Swedish orchards over 6 years. The flight period of <i>C. strobilella</i> was concentrated in May, whereas <i>D. abietella</i> had an extended flight period from May to October, and <i>E. abietaria</i> mainly flew in June and early July. Population densities measured by trap catch and cone density fluctuated between years and orchards, despite these were located within 74 km of each other. For <i>C. strobilella</i>, but not for <i>D. abietella</i>, there was a significant relationship between the number of males captured per trap and the number of larvae per ha or the proportion of infested cones in the subsequent generation. No significant relationships occurred between larval density and trap catch the following year (within generation) for any of the species. Notably, the trap catches were high also after years almost void of breeding material, that is, cones.

The European spruce bark beetle <i>Ips typographus</i> is an important forest pest in Eurasia affecting spruce-dominated forests by eruptive outbreaks, which are likely to become more frequent and severe in a changing climate. It expresses a reproductive diapause to cope with harsh winter conditions. As diapause also affects the activity and voltinism of <i>I. typographus</i>, understanding its regulation by abiotic environmental factors can help to mitigate outbreak risks, for example, by coordinating management measures or adapting silvicultural strategies. While diapause induction in late summer and autumn has been shown to be mainly triggered by photoperiod and modified by temperature, information on environmental cues affecting post-diapause swarming in spring is scarce. In late winter/early spring 2021 and 2023, we conducted a laboratory experiment assessing spring swarming and reproductive potential of <i>I. typographus</i> after diapause termination, applying various temperature and photoperiodic conditions. We used mean temperatures between 13°C and 23°C with daily oscillations of ±5°C and daylengths between 9 h and 14 h (January–April). Post-diapause temperature sums had the strongest effect on spring swarming, modified by daily maximum temperatures, while photoperiod had only a small and ambiguous effect. In contrast, the reproductive potential of dispersing beetles remained almost unaffected by temperature sum, daily temperature and photoperiod. Our results show that spring swarming can potentially start as soon as cold temperatures have terminated diapause in mid-winter. Ongoing climate warming will consequently extend the reproductive season, likely increasing voltinism and population densities of <i>I. typographus</i>.

Our network analysis of interactions between 37 plant families and 14 nocturnal moth families or higher taxon groups indicated a matrix fill of approximately 18.7%, with significant nestedness pointing to generalist-specialist dynamics among plant and moth families. Modularity analysis identified distinct clusters of interactions, suggesting that specific plant and moth families engage in compartmentalised relationships shaped by ecological and evolutionary factors. Dominant groups, such as Asteraceae and Fabaceae among plants, and Erebidae and Noctuidae among moths, played central roles within these modules, underscoring their importance in maintaining nocturnal pollination networks. These findings emphasise the importance of both diverse and dominant pollinator groups in supporting Neotropical pollination dynamics. Our work highlights the need for pollinator-centred studies, the adoption of standardised methodologies, and deeper exploration of exclusive moth pollination to advance understanding of plant reproduction across the Neotropics.
