The results suggest that a one-week trap replacement period, which is the current practise in carrot psyllid monitoring, is too long at the early growth stages of carrot. Regardless of the oviposition (laying of eggs) preference for a certain carrot cultivars, the possibility of a functional push-pull control strategy based on limonene seems unlikely, since the repellent effect of limonene could not be verified. Further field studies with possible repellent compounds, such as winter host volatiles, will be needed to develop an efficient ecological control method for this species. |

It is assumed that climate change will promote pest invasions and their establishment in new regions. We have updated the list of current alien invertebrate pest species in Finland and produced a list of potential new alien pests using a self-organizing map (SOM) that ranks species in terms of their risk of entry into Finland. The 76 pest species recorded included 66 insects, 5 nematodes, 2 mites and 3 slugs. Nearly half of the alien species appeared to have invaded Finland during the last 48 years. The SOM analysis is considered a viable tool for identification of potentially high-risk invasive pests from among the multitude of potential alien invaders, and represents a useful complement to local expert knowledge-based risk assessment of potentially... |
