One of the great things about working for Noldus IT is its involvement in scientific research projects. Because the tools that we offer are used in scientific research, it is logical that we also participate in projects for which such tools are developed.
Aphids and their natural enemies
Leaf sucking creatures like plant aphids are common and can cause considerable damage to plants. Therefore, quite a lot of effort is made to control these tiny creatures. And because of environmental awareness, sustainable methods to control aphids are well developed. Aphids can be controlled successfully with ladybugs (Coccinella septempunctata) and also with lacewings (Chrysoperla carnea). Both species are natural enemies of aphids.

We all know that the majority of plant species depends on pollinators, like bees and syrphid flies, for reproduction. What most of us do not know is that this process is far more complex than it looks at first sight. Think about it: pollinators do not visit flowers to transfer pollen, but to collect nectar. If the amount of nectar in the flowers is too large, the pollinators will not visit other flowers to collect more, so no pollen is transferred to other plants. Conversely, if the amount of nectar is too small, it will not pay for the pollinators to visit those flowers. So plants have to fine-tune the nectar production in their flowers to optimize pollination. And did you know that some plant species even add toxins to their nectar, which stimulates pollinators to move to other plants, bringing the pollen with them ?
