| We have studied the emission of volatile organic compounds (VOCs) from young strawberry plants, cultivars Polka and Honeoye, after feeding by several strawberry herbivores under laboratory conditions. VOC profile of strawberry plants is highly dominated by green leaf volatiles (GLVs), which are released also due to mechanical damage. Our results reveal that strawberry has potential for inducible VOC defence, and this encourages testing the attractiveness of these strawberry VOCs to predatory mites. |

| The black vine weevil (Otiorhynchus sulcatus) is a common pest in Central Europe but rather new on outdoor crops in Finland. Spreading of enthomopathogenic nematodes against weevils by drip irrigation was tested at MTT during 2003-2004. The results proved that at least in small-scale use the nematodes were easily spread through the irrigation system into the field. We were not able to prove the efficiency of the nematodes against larvae because of too low level of both species populations in the experimental cages in the field. |

| Worldwide interest in soil quality evaluation has increased rapidly throughout the past decade, prompting us to evaluate the long-term impact of four cropping systems on several biological, chemical and physical determinants of soil quality. We hypothesized that after 17 years several of the determinants would show significant differences between conventional cereal and low input/organic rotations. Four crop rotations were imposed on a silt soil from 1982 through 1999. Rotation A was a conventionally managed cereal rotation that received 100% of the recommended mineral fertilizer each year. Rotation B was also managed conventionally from 1982 until 1993, although it received only 50% of the recommended mineral fertilizer. From 1994 through 1999, rotation B... |

| 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... |

| An organic strawberry field experiment was started in 2000 at MTT Ecological Production in Mikkeli to study the influence of mulching materials on the growth, yield, microbiological fruit quality and strawberry mite. Mulching materials are black plastic, flax fibre mat, green mass, barley straw, buckwheat husk as well as pine and birch woodchips. |
