| | Aphid - Wikipedia, the free encyclopedia |
 | | Aphids, also known as greenfly/blackfly or plantlice, are minute plant-feeding insects in the superfamily Aphidoidea in the homopterous division of the order Hemiptera. | | | About 4,000 species of aphids are known, classified in 10 families; of these, around 250 species are serious pests for agriculture and forestry as well as an annoyance for gardeners. | | | It is possible for aphids to migrate great distances depending on the weather patterns, for example, the Lettuce aphid spreading from New Zealand to Tasmania. |

| | Aphids are small, mostly less then one tenth of an inch, soft-bodied insects of the family Aphididae. | | | The daylily aphid is light green in color and feeds in colonies between the leaves of the plant, inserting the mouth parts into plant tissue and sucking up the juices. | | | Aphids are especially partial to plants fertilized with large amounts of nitrogen. |

| | Aphids Management Guidelines--UC IPM |
| | Because many vegetables are primarily susceptible to serious aphid damage during the seedling stage, losses can be reduced by growing seedlings under protective covers in the garden, in a greenhouse, or inside and then transplanting them when they are older and more tolerant of aphid feeding. | | | Aphids are very susceptible to fungal diseases when it is humid. | | | Aphids are small, soft-bodied insects with long, slender mouth parts that they use to pierce stems, leaves, and other tender plant parts and suck out plant fluids. |

| | Aphid |
| | Aphids, or plant lice, are small, soft-bodied insects which are common pests of nearly all indoor and outdoor ornamental plants, as well as vegetables, field crops, and fruit trees. | | | Migrating aphids are attracted to the yellow-green color of unthrifty plants. | | | In most cases, the ants protect aphids that have already established themselves on the plant and these aphids or their eggs and keep them through the winter in their nests. |

| | Colonies of the aphid larvae, which carry tufts of white cottony fluff on their backs, look like snow covering the branches on which they are feeding (Figure 3). | | | For instance, there could be another insect, probably a fly or wasp, that n ormally parasitizes the aphids and controls their populations naturally. | | | There is a possibility that the widespread use of pesticides, or elimination of some important resource such as weedy flowers on which the adult parasites feed, upsets the natural balance and leads to an overpopulation of their potentially pestiferous prey. |

| | APHID MANAGEMENT |
| | Aphids may be winged (alate) or wingless (apterous). | | | Most aphid populations are moderated by natural controls that include environmental stresses (high winds, heavy rains, extreme temperatures, etc.) and natural enemies (lady beetles, green lacewings, syrphid fly larvae, damsel bugs, braconid and chalcid wasps and parasitic fungi). | | | For example, the cotton aphid occurs on chrysanthemum and cucumbers in British glasshouses, but aphids from chrysanthemums will not colonize cucumber, and vise versa - although both can be reared on cotton. |
