Aphids are insects that suck the lifeblood of the foliage causing the leaves to wilt and turn yellow. As they feed, aphids exude a sticky honeydew that attracts ants, which feed on it. A much like ants that keep aphids producing this substance to them. When the infestation increases can be observed that excrete sticky honeydew aphids.
Usually attack weak and stressed plants. Some species prefer young shoots and succulent, and others like the older foliage and even floral buds.
Location and identification of aphid
Find rows of ants near the plants and find aphids. You can find them, too, under the leaves clustered around the nodes of the branches and shoots growing.
This plague carrying bacteria (uses vector), fungi and viruses. Aphids are vectors of more viruses than any other source. The destructive blackish mold also grows on the honeydew. They may be useful yellow sticky traps, for a scan mode of the area, if any appear.
Damage due to a plague of aphids
Aphids live to suck the lifeblood of the foliage, causing the leaves to wilt and turn yellow.They prefer to attack, weak and stressed plants, sprouts and succulent, and the leaves and even the flowers. OFTEN ants (attracted by the aphids secrete honeydew) will sample activity reaching around plants to transport the greenfly unaffected plants.
Removing aphid infestation
The aphid is not too harmful but it can cause some discomfort and damage to plants. If the pest is not large individuals can remove it manually.
If there is already a colony of aphids in our garden, it is important to act with an insecticide (systemic or contact) repeatedly to eliminate or reduce pest significantly.
Methodology for spraying insecticides
Fill the sprayer with water quality (ideally weak mineralization) and add the recommended product by manufacturer.
We are interested spray the plants (bottom-up and top-down) with a thin but consistent layer of the prepared mixture. When the aphid, a pest that spreads fast, it is important to properly apply the product with an attendance of 3-5 days until the total disappearance of the plague. We recommend applying the product late in the day outside and inside (using nocturnal hours, so that the product persists on the ground).
