Green Gardener Beneficial Aphid Predators for use under-glass (Aphidius 500)

الوصف

Control aphids naturally by introducing Aphidius AS SOON as you see aphids (greenfly and / or blackfly) and the temp is 10°C/50°F. 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. This listing is for 500 Aphidius in a tube.
