There are at least 25 species of aphids infesting greenhouse crops. Aphids have pear shaped bodies, can be winged or wingless. They are slow moving insects 1 - 4 mm or 1/25 inch long. The color can range from yellow, green, red, purple, brown to black. White cast off skins can be found in the presence of aphids. Aphids suck sap from plants, excrete honeydew, inject toxic substances into the plants and transmit viruses. Ants can disturb the biological control of aphids because Because of the fast reproduction of aphids, several natural enemies should be used at the same time.
