Chrysoperla carnea as a natural enemy
The Chrysoperla carnea is a natural enemy of aphid. In the larval stage in particular, this insect is very effective against aphid. The larvae of the Chrysoperla carnea are very aggressive and after administering to the crop they will start searching prey immediately. The prey is drilled by their jaws after which they spray paralyzing juice into their prey. This juice causes the aphid to become fluid from the inside out, enabling Chrysoperla carnea to suck up the content. In the crop only the shriveled bodies of the aphid remain.
What does the Chrysoperla carnea look like?
The larvae of the Chrysoperla carnea are 2 - 10 mm in size and have a grey-brown body with big jaws. In this stage the Chrysoperla carnea are not yet able to fly and must therefore be released near their prey. An adult Chrysoperla carnea can be recognized by its slim, green body of around 12 mm long, with large finely-nerved wings. The Chrysoperla carnea is most active at temperatures between 12 and 25°C.

How to protect bumblebees from heat
When the sun is very strong, the temperature in the greenhouse increases. This can cause the bumblebees in the crop to overheat. This has a negative effect on pollination and, in the worst-case scenario, bumblebees can die.
