Researchers to fight killer slugs

10.06.2005


If you see men crawling around in the neighbour’s garden at dusk wearing headlights, it may well be that they are researchers hunting for Spanish slugs.



Spanish slugs were previously seen as a garden nuisance, but now they have started to become a serious problem also for commercial horticulture, affecting strawberries and cabbage. A glaring example is garden owners in Hordaland county, who has had up to hundred thousand slugs in their garden, while a lot of strawberry and cabbage crops were lost various places along the western coast.

The Research Council of Norway has recently awarded funding for four years to a project for mapping the spread of Spanish slugs, also known as killer slugs, Iberian slugs or Arion lusitanicus in Latin. They will study the biology of these slugs and try various methods to get rid of the annoying snails.


Therefore the researchers will be the busiest in well-kept villa gardens and in berry- and vegetable farming. They will crawl around with headlamps at dusk and in the dark, they will weigh, count and register Spanish slugs and also other slug species.

For the moment researchers do not know enough about the biology and living habits of the Spanish slug in Norway, even such fundamental aspects as life cycle, wintering and spread must be researched on much more.

In the first year of the project we will mostly do basic research and this can give us a much better understanding of how this species live in relation to factors in the environment, and consequently, how we can fight against it.

It is also important to increase our knowledge of which species of plants the slug prefers and which ones it avoids.

It is urgent to find efficient measures. Clear indications of crossing between Spanish slugs and black slugs have been found, just like in Sweden. Some have feared that such a crossbreeding can develop into a kind of superslug.

The brown slug, as the Spanish slug got to be called by “the people”, was first observed in Norway in 1988. It can be found naturally in many countries, but it creates a problem in Switzerland, Austria, Germany, parts of Poland, parts of the Netherlands and Belgium, and in Scandinavia without Iceland and the Faeroe Islands.

The natural enemies of the Spanish slug are investigated in many countries. A few methods have been observed and tested in a scientific way, these include both insects, animals and different slug agents. The Norwegian project on Spanish slugs has cooperation partners in several European regions, among other places in Sweden, Scotland and England.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
