Hoverfly as a natural enemy
The hoverfly Episyrphus balteatus is the natural enemy of aphid. When the hoverfly is in the larval stage, it feeds with aphids. Using its mouth jaws, the larvae will grab its prey after which it empties it by suction. Hoverflies lay their eggs in aphid nests, to be able to easily reach their prey.
The adult hoverfly can be recognized by a slim body with a shiny, coppery chest with longitudinal stripes and yellow-black striped abdomen. That makes them slightly resemble wasps. The larvae of the gall midge are 10 to 20 mm in size and have a transparent body with an irregular color pattern. Even at a temperature of 8°C they are active.

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.
