Aphids are small insects with long spindly legs and antennae. During the summer they are wingless as they feed on the plant, but as the population increases winged forms appear which help to spread the infection. Aphids feed by sucking the sap from the plant, this stunts the growth and causes distortion of the growing point. The aphid absorbs large quantities of plant sap and this sap contains excess sugar that the aphid excretes as honeydew. This is sticky and coats the lower leaves of your plants and often a sooty mould will develops on the honeydew, which is unsightly and reduces the plants ability to manufacture food causing further loss of vigor - this is usually the 1st sign of an aphid infestation. Aphids are fast breeders - each female is capable of producing 6-8 live young daily over a 2/3 week period. Importing just one aphid on a plant can quickly lead to severe infestation. It is essential to check all plants brought into the greenhouse or conservatory for signs of aphids and deal with them immediately. In summer winged females will come in through greenhouse vents, so during warm weather be extra vigilant. To control aphids :-
- Use Aphidius when aphids are active and the average temperature is 10°C/50°F.
- If the temperature is below 10°C/50°F, use SB Invigorator to hold the fort until temperatures rise and then introduce Aphidius.
- If the infestation is very heavy then spray with our natural spray SB Invigorator first to reduce numbers before introducing Aphidius - see our Aphid Emergency Pest Pack.
- Ladybirds and Lacewing Larvae can also be used to control HEAVY infestions in your greenhouse / conservatory.
Control aphids naturally by introducing Aphdius AS SOON as you see aphids (greenfly and / or blackfly) and the temp is 10°C/50°F. This naturally occurring aphid parasite is capable of attacking a wide range of aphid species. Ideal for use in conservatories / greenhouses / growrooms / hydroponic systems and safe to use on food crops.
Aphidius is supplied in small tubes, which are opened in the greenhouse / conservatory and the small Aphidius will fly out and search out the aphids. Once the Aphidius finds an aphid, it lays an egg in the aphid. As the egg hatches the resulting larvae feeds on the inside of the aphid destroying it. Following pupation, the adult leaves the dead aphid and will then search out its own aphids to infect. As the aphidius population increases the aphids will be controlled. As well as directly controlling the aphids, the activities of aphidius "upset" the aphid colonies and as a result they produce a warning pheromone which alerts the whole population, which try to escape. Many fall to the ground and die helping the parasite control aphid numbers. Introduce Aphidius as soon as aphids are present and the average temperature is 10°C/50°F.
N.B. If you have recently used a chemical spray i.e. within the last 2-3 weeks, please contact us (email@example.com) to check how soon Aphdius can be introduced?
