WAGENINGEN – Insects are choosier than you might think: whether or not they end up feeding on a particular plant depends on much more than just the species to which that plant belongs. The quality of the individual plant is an important factor as well. As is the variety of other plants growing around it. But what, ultimately, makes an insect choose one plant over another?

It’s no secret that many insects are struggling worldwide. But we could fix these insects’ problems, according to more than 70 scientists from 21 countries. Their road map to insect conservation and recovery is published in Nature Ecology & Evolution this week. From urgent ‘no-regret’ solutions to long-term global comparisons.

Micro-organisms living inside plant roots team up to boost the plant’s growth and tolerance to stress. This research is featured this week in the scientific journal Science.

If you’re small, smells are a good way to stand out. A team of researchers led by the Netherlands Institute of Ecology (NIOO-KNAW) has demonstrated for the first time that two different types of micro-organisms – bacteria and fungi – use fragrances, known as terpenes, to hold conversations. And that’s not all. “We actually believe that terpenes are the most popular chemical medium on our planet to communicate through.”

Sorghum is the fifth most important cereal in the world. In sub-Saharan Africa, many farmers rely on this grain for food and feed. But Striga, a parasitic weed, can have a devastating impact on crop yield. With an 8-million-dollar grant from the Bill & Melinda Gates Foundation, an international team will now explore the potential of soil microbes to offer crop protection. The Netherlands Institute of Ecology (NIOO-KNAW) is coordinating this 5-year project.

Tiny predators in the soil can literally sniff out their prey: soil bacteria, which communicate with each other using scent. A team of researchers from the Netherlands Institute of Ecology (NIOO-KNAW) has discovered that these predators - called protists - 'eavesdrop' on the bacteria's communication. It's a discovery that opens up perspectives for agriculture. The results are available online this month in The ISME Journal, from the publishers of Nature.

Thiacloprid, a widely-used pesticide, can cause a large-scale decline in freshwater insects. This was discovered by a team of researchers from Leiden University, including current NIOO-director Geert de Snoo.

Microbes, like humans, can eat 'junk food' and grow fat. This even happens when you might not expect it, according to NIOO researcher Kyle Mason-Jones

Zonder gezonde, biodiverse bodem geen gezonde samenleving. Maar hoe vertaal je dat in goed beleid?
