Aphids may be better known as greenfly or blackfly. Almost any crop can be infested with them and they are particularly common. This pest family is one of the biggest on the allotment.
The most common signs that you have Aphids are:
- Leaf Distortion
- Leaf Yellowing
- Sticky upper-surface or leaves
- White skins on upper surface of leaves
- Sometimes, black sooty mould from sticky honeydew produced by aphids
Aphids can be active all year round but are most active at temperatures between 10 and 35.
How It Works
These tiny braconid wasps are released into the same environment as the Aphids and will lay a single egg inside the aphid, after 2/3 days the egg hatches and wasp larva emerge which feed on the aphid.
If you are aware that you have got an aphid problem, the sooner you release the wasps the more effective they will be. Even more effective if you do not have an aphid yet but are aware that they usually come around this time.
Using this method is a completely organic method to get rid of Aphids and is an effective alternative to chemicals.
How to Use
Once you are in your greenhouse next to the plant that needs protection, open the bottle and lightly sprinkle the contents of the vial onto the leaves of the plant. After this, leave the open tube on the soil of the plant so that the remainder can fly away.
If the husks fall off the leaves and onto the soil or bench, don’t worry too much, just avoid sprinkling them onto areas that are likely to get watered or cultivated. If you would only like to treat a small area, you may just lay the tube on its side with the top open and let the insects fly out once they have hatched.
If you need to wait before you put them out, make sure they are stored in a cool place to stop them from hatching and dying from starvation. The recommended temperature for storage is between 5°C - 10°C and you should ensure that the tube is stored in the dark, on its side. Do not store them for more than two days. The sooner they are released the more success you will have.
These wasps are the most effective when they are kept in temperatures above 15°C.
